AMD Phenom II X4 965 BE had a locked core, could this mean my CPU is faulty?

Q: AMD Phenom II X4 965 BE had a locked core, could this mean my CPU is faulty?

So I purchased a new CPU a couple months ago and didn t bother to mess with the Bios after installing it Anyway the CPU I purchased was an AMD Phenom II X BE which as I understand is supposed to have all four cores unlocked from start with no need to do anything yourself Anyway some time had passed and about a month ago I was in my Bios messing around with some settings and noticed that under CPU Settings it showed something like this Core - Unlocked Core - Unlocked Core - Unlocked Core - Locked I started up my computer without making changes to check what my computer said and sure enough in task manager it only showed three cores I m almost positive that I d remembered seeing four cores in the task manage on multiple occasions before but of course couldn t be sure So I m not sure if it was always like this from when I installed the CPU or if something changed it for the first month or two I had it installed Anyway went back into Bios and changed it to Unlocked and now all four cores show as unlocked and my computer seems to be running fine but now I am unable to see the temperature readouts for each of my cores--which I understand is a side effect from unlocking cores though I shouldn t be having that problem considering the BE is supposed to come with all four cores unlocked AFAIK I m not too concerned about the temperature thing really but I m just wondering if this would have any effect on my computer or if it could mean that the CPU is faulty or something along those lines I appreciate mean CPU 965 locked core, had BE AMD a faulty? this Phenom X4 is could my II any help thanks nbsp

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

A: AMD Phenom II X4 965 BE had a locked core, could this mean my CPU is faulty?

I think the the X4 BE is supposed to have 6 cores, with 2 of them locked out. It almost sounds like you have an X3, with 1 of 4 cores locked out. My 970 BE showed 6 cores, with 2 locked out, when I first got it. But I think I may have over-cooked it, or something, when I enabled all 6 cores, and overclocked it, because now it only shows 4 cores. None are locked, though. It runs fine at 4GHz, with 1.5V to it, and 17V to the cooling fan.

I'm looking at new laptops and would like to know what ppl think of the AMD Phenom II Quad Core Mobile Processor N930 VS the Intel Core I3 350M Processor.

Thanks for the input.

So I'm looking into building my first computer, and saw that Phenom II 6-core was much better than a Core i7 quad core, plus it cost much less? I'm wondering why this is. The links for both:

Phenom II 1055T x6

Core i7 920 Bloomfield x4

I know there's something I must be missing, but I can't quite tell.

A:A question about Phenom II vs Core i7

Don't believe all of the marketing hype. Both have their strengths and weaknesses, and the fanbois of each will tell you why one is better than the other.

The i7 has eight virtual cores, the Phenom has 6. The Intel will perform better at certain tasks than the Phenom. In the end, it's a price/performance issue.

My personal machine has a Phenom in it. The machines I spec for work have i7's in them. If I had the money, my own machine would have an i7, simply for the multi-threading features and better resource usage. Intels also run cooler in my experience.

I consider myself fairly unbiased, so there's my $.02

EDIT: As stormy13 has pointed out, my statement that the i7 has eight virtual cores is incorrect. I often mistakenly think of it as an 8 core CPU. In reality, the i7 920 has 4 physical cores, and 4 virtual cores, not 8 as I have stated above.

So I have a little question, which one would you choose and why?

I'm building a new computer but I cant decide which one to use,
the price is the same so it's even harder to decide...I think I would
take the Phenom but which would You choose?

AMD Phenom II 1090T Black Edition (HDT90ZFBGRBOX)


Inte Core i7 930 (BX80601930)

A:AMD Phenom II x6 or Intel Core i7

I am an AMD convert and own the 1090T, so guess which way I recommend .
If you are into overclocking, these things are great. Had mine running @ 4.5ghz and will run 4.0ghz 24/7 on 1.35 vcore.
It may depend on what motherboard, RAM etc costs are. i7 uses triple channel RAM so the costs will be more for that. Mobo's are generally more expensive for the i7 series too.

Hi guys I was wondering what your thoughts are on this plan of mine to buy one of these i5 X4 BE, II vs AMD 955 Phenom Core recommendations? processors and to compare a Biostar mobo to an MSI one which seemingly have very similar features I have a small table comparing their Core i5 vs AMD Phenom II X4 955 BE, recommendations? price points but I need an expert opinion on which one is better to spend my money on because I am limited to a budget of CAD - Also I need to know whether in the future I can count on processor upgrades from either without having to switch boards and what are my options I am hinting at core processors for both Intel and AMD that are planned for release this year I really appreciate your thoughts guys PS I already own a GTX core and an Earthwatts W PSU cert My Case contains fans of which are LED and out of them are Thermaltake Blue smart fans I wasn t sure if that info would be a factor in choosing the correct CPU Mobo combo nbsp

A:Core i5 vs AMD Phenom II X4 955 BE, recommendations?

The Core i5 750 is definitely a better processor. However, being an AMD fan, I also love the the Phenom II 955BE. If your budget permits, then go for the i5 setup.

Both the Phenom II and the i5 cater to each manufacturer's flagship socket. The LGA 1156 from Intel and the AM3 from AMD are here to stay. So you wouldn't really have to switch boards if you upgrade the CPU in the near future. However, in this regard AMD is more reserved. Intel seems to come up with new sockets fairly quickly.

The 6 core processors are Intel's Gulftown and AMD's Thuban. The Gulftown will be based on the LGA 1366 socket. The Thuban will be AM3. So if you would like to upgrade to a 6 core system without swapping the motherboard, AMD is the way to go.

All looks fine in your system. Just feel that you may be cutting it a little close with that PSU.

AMD's six-core Phenom II X6 CPUs will underclock three cores and automatically overclock the other three

Posted by Sean Portnoy @ 7:57 pm

More details have emerged about how AMD?s forthcoming six-core desktop CPUs, the Phenom II X6 lineup (a.k.a. Thuban), plan to handle all that processing power when most applications still can?t make use of four cores.

Hi Guys,
I'm, trying to decide which of the said two processors to buy for my new machine. They are the same price. I've seen reviews of both but now direct ones. I've heard good things about the phenom's power consumption.

Any thoughts anyone?

Hi, I have a AMD Phenom X4 Quad Core 640 3.0GHZ Overclocked at 3.3GHZ

On the AMD website it states that the maximum tempruture is 62 degrees, is this for the processor, or the cores?

The cores together are the processor, thus, 62 degrees celsius is max for the whole chip.

I can either get a i7 920 or phenom II. Which one should I get?
I am using then for gaming.

A:Core i7-920 vs Phenom II x4 3.7GHz for gaming

Which stepping is the i7 920? The D0 overclocks much better than the C0 stepping.
But if they're the same price (including the price of the motherboard) I'd say go for the i7 920, mine still plays all modern games without any problems. Or if you can find an i5 2500K or 3570K for around the same price then go for those because the 920 is already 2 generations old and a bit of a power hog.

I was just wondering: I read it is possible to unclock the 4th core, but I also read that
only some bios versions and motherboards supported it. So my question is, Does my motherboard (M4N78 SE) support unclocking that core?

And if it supports it, how would I be able to unclock it?

Thanks in advance,

I am working on building a new PC for myself I tried to be very careful when I installed AMD Phenom Installation Core Quad CPU the heat sink I slipped slightly causing a slight side and maybe a little up down movement after the heat sink thermal compound had touched down on the CPU Question Should I try the PC for a while with it like it is It is my understanding that modern motherboards will shut down the PC automatically if the CPU gets too hot I am thinking to give it a try tomorrow evening and watch the CPU temperature in the BIOS for a while on first boot Common sense says that although the CPU installation may not be perfect that the thermal compound will over time spread into any gaps that may be present I am sure that people that build PC s for a living occasionally slip when installing a heat sink on a CPU I have some Artic Silver on hand in the Fridge I am just trying to get out of extra work Thank You In Advance nbsp

A:AMD Quad Core Phenom CPU Installation

It will be OK , for a little side slippage happens. The close proximity of heat sink and cpu surface is paper thin, so it will be fine, as long as you started with a good compound layer. When using a tube of thermal compound, I only spread it on the surface of the cpu. The thermal compound will fill the slight gaps. Everyone should re-apply new compound every two years, for it hardens with heat over time.

I recently bought Phenom II x4 960t, and I asked someone to install it for me.
She accidentally bent 1 of the pins in the processor. We manage to straighten the pin and the processor works fine.

Now, when I'm starting my PC, BIOS shows that it has 4 cores, but in CPU-Z and MSCONFIG it only shows 1 core. In MSCONFIG>BOOT>ADVANCE OPTIONS.., there is no options for the number of processors. My Motherboard is ASROCK N68 S3 UCC,

Thank you!

A:Phenom II x4 960T, only 1 core is used or working. HELP!!

Welcome to SF.

I'm sorry, but CPU-Z should show 4 cores and 4 threads. If it doesn't the bent pin may indeed be the problem.

The A8 is a pretty new chip, so not many people have much real experience with it. I'm sure if you Googled it you could get several reviews. I don't know if it has made it on the list, but here are the Passmark ratings of CPU's. I believe a few are mobile. Don't confuse the desktop ratings with the laptop ratings of the same chip.

Sup all, A friend of mine has a Phenom II X2 550, that he Unlocked to a Quad Core.
Then in MSCONFIG, i Enabled all 4 Processors upon boot up.
He restarted, and lines appeared throughout the POST screen and the resolution in windows was set to low.
So he immediately reverted back to one core.
Then he tried to play Call of duty world at war and was experiencing Low Fps and allot of lag.
Some games wont even Load.

CPU-Z shows 1 Core.
Windows Device manager Shows 4,
Resource Monitor shows activity on all 4 Processors,
The BIOS shows 4.......

Tried a system Restore.
The latest Drivers have been installed for Mo/BO.

A:amd phenom x3 triple core processor 8650 2.3 ghz toliman

Assuming that they are in working condition, those two guys are good general-purpose CPUs although not anywhere near the top of the scale. 15 bucks apiece is a low price for them.
Look here. Use their score to compare to other CPUs you have that they benchmarked. Your current processor is here.

Also, from here there are more comparisons. It appears to be around 1/3 the power of a modern top-dog CPU.

Still, please note that they are compatible with AM2+ and maybe AM3 sockets ONLY (being from AMD), so you won't be able to place them in your current PC nor use your current CPU cooler on them.
Then again, good AM2+ boards can be found for pretty damn cheap in thrift shops (look inside the used PCs they have too) or on ebay.

A:Processor picking, AMD Phenom 9600 VS AMD Phenom II X4 940 Black Edition

Between the two, it is a no brainer. Get the 940. Next IMO you use an amd chipset board for an amd build and an intel chipset board for an intel build.

When you use third party chipset boards ie nvidia, sis, or via, you are asking for problems.
Nvidia makes fine video cards; their motherboard chipsets.... that is another matter.

Or faulty motherboard? it s been stable and temps have been fine lt My motherboard is a Asus P N-E SLI board The computer is dual boot to Vista for general use and XP x for games ONLY XP IS OVERCLOCKED Vista is not overclocked at all Only the GPU is overclocked in the computer Now the problems started when I moved the computer All the games on x crashed unless I underclocked the machine except UT ancient game which garbled the graphics weapon textures on walls etc I found out it was because somehow the card wasn t plugged in properly - so I pushed it back and I was able to play again Since then sometimes the card is alright and other times it isn t The other day I was playing fallout graphics intensive game for around hours without any problems But right now I boot to vista and within a minute it crashes Other times I was programming not even using graphics and the mouse suddenly has a flickering box around it - then the computer crashes When it crashes the screen goes weird colours like its rendered the screen as bit colours rather than bit and shortly after I get a blue screen with it complaining about a graphics DLL At first giving the card a wiggle in the PCI-E slot fixed it Now I ve discovered that when the garbled graphics come up if I physically push the card upwards in the PCI-E slot whilst the PC is still on they go away by this time the computer has crashed amp so I have to reboot anyway It s nothing to do with the drivers I ve reinstalled them on XP and besides the problem happens on both of the OS on the computer Vista seems to be considerably worse though - XP only crashes once in a while whereas Vista seems to be more unstable If you push the card up quickly sometimes Vista quot recovers quot It says quot the display ddriver stopped responding and has recovered quot or something like that You can then use the computer normally If I push the card down when the computer is working fine the computer crashes Any suggestions whether it s the card or the motherboard I removed the card blew dust off it etc put it back into the machine and the problem still happens although it initially solved it I don t want to spend on a new card to find that it s the MB that s the problem I m wondering if the card is fine since it doesn t have an issue with hours of gaming on a good day If it s a lose connection what can I do about it it s fully pushed into the motherboard If you ve read this far thanks nbsp

I believe drivers? faulty BSOD 116 card or graphics faulty the initial crash was caused by overheating Based on the fact that I have gotten it to work for a short amount of time more on that later Booting up with the drivers for my graphics card enabled causes BSOD to appear but when it is disabled everything is fine I can boot into safe mode and I have already reinstalled windows My motherboard is Asus B M-e and my graphics card is Nvidia EV A GTX How I got it to work for a short amount of time I reinstalled windows and then installed my integrated Ethernet driver After that was out of the way I installed and used driver booster to install the rest of my drivers I then noticed there was a missing driver that the program could not install that was named Simple PCI Controller So I thought I should install that driver using my motherboard's driver installation disk It then worked up until I decided to change the settings in Nvidia Control panel I also do not know how faulty graphics cards behave so it might be my graphics card The game I was playing when this started was Life is Strange if that is needed

I recently bought a new, 3rd party power cord for my Toshiba Satellite L300 from eBay.
Recently I've noticed that my battery stops charging earlier and earlier. At first it stopped at 87%, then 83%, then 80% all in one week. I've had the computer for about a year which seems a bit early for it to start degrading so fast, so could it be the power cord?

The Toshiba cord says Model: PA-1750-29, Input: 100-240V~ 50-60Hz 1.5A, Output: 19V[solid line above a dotted line]3.95A
The 3rd party cord says Model: PA-34671ACA, Input: 100-240V~1.5A 50/60Hz, Output: 19V[solid over dotted]3.95A

If the new cord is harmful to my battery, I can just solder its input plug onto the Toshiba charger (that's the only bit that was broken) but I'd rather not risk breaking two power cords if I don't need to.

Two times in the last week my monitor (a KDS visual sensations CRT) has come on with the image looking like an hourglass (wide at the top and bottom, pinched in the center). This happened imediately upon boot up and both times rebooting has returned the monitor to normal, leaving the computer running does not bring the problem back. Which is more likely, that my monitor is beginning to fail or maybe my graphics card (a saphire, ATI radeon 7000) is failing? Is there some way (other than swaping my monitor out and trying another as this seems so far to be an intermitent problem and may not arise when a new monitor is conected) to check and see which it may be?

I am going to upgrade to a new processor soon and I was just wondering if my motherboard will run a Phenom II processor. It will run a Phenom processor and also Phenom FX, which hasn't even been released yet, so it seems like it would run most new AMD processors.

Here is the motherboard:


A:Will a motherboard that will run Phenom also run Phenom II?

It most propably won't. You will at least need a BIOS update. Actually it will. :O
Go here: search for your motherboard, choose WinXP (or any other, as it doesn't even matter), choose BIOS [BIOS history], choose the latest, 1001, BIOS, download. Then... I'm not sure, but you might need a floppy drive to update the BIOS, though some newer board can be done with a USB drive.

Hmm, I guess you should read some reviews. But just from the specs the AMD has 6 GB ram instead of 4. Has a DVD burner where the Intel shows no optical drive. It only has W8 8.0 where the Intel has 8.1. But some people may prefer 8.0.

Read reviews. See how each performs. If you don't wish to use it to burn DVD then the optical drive, or lack thereof may not matter to you.

Edit: Oh, and the AMD is about $80 cheaper.

Hi, Currently I'm using a dual core 6850 and I'm thinking about buying a quad core. I have a PSU of 500 W as spare.

Can i replace the CPU to a Quad Core without changing the cooling system?

A:replace dual core CPU by quad core what about heatsink? in Mini Tower 755 Optiplex

These are the specs of the spare PSU. Aren't they better than the original Dell PSU?
That power supply is ATX and not EPS12V
Better is not the issue.  Dell power supplys are 80 percent efficient not 70 percent ATX.  The -5v rail is an issue as well as this may cause a motherboard fire or damage your system.  Its a dead giveaway that this is a power supply from 1990 to 2000.
What current is on which rails is not trivial. There is a single 12V RAIL on that unit and its max is 17A
EPS 12V units have multiple rails of 12V @ 18 amps each.  MAX Power on the 12V rails is 264w not 204w
That unit has a lot more on the 5V and 3.3V rails at the expense of the 12V rails and CPU 4 pin connector. So no that spare unit is not likely to work well if at all.

Recommended update or replacement is EVGA 750B1

Hello friends,
I m very eager to know that whats the actual difference between a Core 2 Duo processor and a Pentium Dual Core processor, other than their proceesing architecture?

According to most benchmarking sites including Tom's Hardware, Core 2 Duo E4300 or 6300 performs better than Pentium Dual Core 820 in almost all benchmarks.....whereas C2D E4300 or E6300(1.8 and 1.86 Ghz respectievely) are having MUCH lower clock speeds than Pentium D 820(2.8Ghz). Why like this???

I have 2 systems, one with C2D E4300 1.86 Ghz and another(from which I am writing this thread) is Pentium D 820 2.8Ghz. But I dont see any MUCH performance difference in reality, although in multi-tasking and gaming C2D system still performs better.

Can anybody please explain me in details.....
Thanks in advance.

A:Why Core 2 Duo outperforms Pentium Dual Core even when C2D has lower clock Speed??

The Core 2 Duo doesn't share the same architecture as the older NetBurst architecture of the Pentium D, which is also shared by the Pentium 4. The Pentium D is effectively a pair of Pentium 4 CPUs on one die. The Core 2 Duo architecture allows for a lot more processing to be done in one cycle, hence more information can be pushed in, say, 1 million cycles by the Core 2 Duo than the Pentium D. As for 'reality', there obviously won't be much difference when both systems are used for stuff like playing music etc. But the real differences will show up when you tax them, such as when playing an HD video without a video card supporting HD-decoding where the Core 2 Duo will be able to process information much more quicker than the Pentium D and so you will have a smoother image. Check on Wikipedia for more in-depth details.

I have two laptops made by the same manufacturer and same year, but one is a dual core laptop with an SSD harddrive and the other is a quad core laptop with a regular hard drive. Both laptops run Windows 8.

I would like to transfer my programs and files from the dual core to the quad core. However, obviously the quad core has different hardware.

I am wondering if I simply remove the SSD from the dual core and put it into the quad core (replacing the quad's primary hard drive with the SSD) and simply boot up the quad core, would that be sufficient? Will the quad core recognize the hardware mismatch and automatically correct the drivers, while keeping my programs and files?

Or is there some other, efficient way to make the transfer? I really want to avoid having to reinstall all my programs.

Thank you

A:Transfer programs and files from Dual Core to Quad Core

There are a lot of third party tools designed to move a Windows installation to new hardware. I prefer using native Windows tool Sysprep for this, mainly because the method is the one and only Microsoft supports and recommends but also because it has never failed me.

The method is described in this tutorial on our sister site the Seven Forums and works also with Windows 8: Windows 7 Installation - Transfer to a New Computer - Windows 7 Help Forums. Method One in tutorial would be ideal for you for moving the SSD to new computer.

Read the information and warnings in the beginning of the tutorial carefully, especially the warning about Windows needing to be reactivated is important. Come back if you have any questions.

Bearing this in mind what would be the best Processor for the Intel Core i5 3.4 GHz Quad-Core (BX80637I53570K) Processor and what would be the maximum Memory and Storage I could attach to it? ( I preferably want 8GB of Memory and 1tb of storage ) but I can be flexible.

A:What would be the best motherboard for a Intel Core i5 3.4 GHz Quad-Core (BX80637I53570K) Processor?

The CPU you want is the i5 3570K. That runs on the socket LGA 1155. When you are on a budget, any mid range mobo will suit your needs. Use the savings from the mobo towards a better HDD or even an SSD. You will also need a GPU.

I would recommend the ASUS P8Z77-V LK motherboard. As for RAM, 8GB is enough. As for the HDD, 1TB is great. I recommend the WD Caviar Black 1TB HDD.

Make sure you can get in a GPU.

I'm trying to decide between two different Acer Aspire Notebooks.
One has:
2.20 GHz AMD V Series V120 single-core processor with 512 KB L2 cache and 1066 MHz front-side bus
250 GB SATA hard drive (5400 RPM)
3 GB of installed DDR3 RAM (1066 MHz; expandable to 8 GB)
ATI Radeon HD 4250 graphics (with 256 MB of discrete video memory) It provides up to 1919 MB of total shared system memory

The other has:
AMD Athlon II X2 dual-core P320 processor
2.10GHz, 1066MHz Front Side Bus, 1MB L2 Cache
2GB DDR3 system memory
250GB SATA hard drive
ATI Radeon HD 4250 graphics with 256MB of dedicated system memory

Which would be better for simple computing, surfing, and streaming videos?

IMO the dual core, but it obviously takes more power, though you don't mention battery life or portability.

I am about to buy a new CPU. What CPU would be better, Core 2 Duo E8400 or Core 2 Quad Q9400, considering I do the following things on the computer:

- A lot of Visual Basic and Photoshop
- Surfing
- Listening to music
- A little *gaming* (some old games like CS or something).

Is it possible to change the dual core processor I have for an i5 processor, is this type of motherboard capable of taking it? I have some screen captures from CPUID of my system specs, hopefully that will be enough info. If it can't take the i5 could it take any other quad-core processor?

I have a Compaq Pressario desktop PC, Windows 7 64 bit, 4GB DDR3 RAM.

Title says it all. Before I installed Hyper-V, Windows shows all 8 threads. . . After, only 1, and VMs were definately sluggish. Has anyone else had this issue or know how to fix it? This Windows 8 pre-release would otherwise be perfect for me as it's the only way I can have Hyper-V AND my internal mobile broadband card fully functional at the same time...

Thanks in advance.

A:Core i7 w/7989 M3 x64 only shows as 1 core after Hyper-V installed???

Welcome aboard, Joey

Actually I have never used hyper V ..... I use VMWare for my visualization needs . There is a settings menu by which I am able to fit the number of processors and number of cores per processor for the guest os . I guess hyper V also have such a setting .

Moreover, in VMWare, you are to install VMWare Tools to make the vm run flawlessly, and it makes mouse integration and network etc drivers workable in the guest . Is there such an option in Hyper V ? If so , do it .

Okay, here is the scenario.
There are 2 laptops.
One has a 3.0GHz single core.
The other has a 1.5GHz dual core.
The thing I'm asking is: When you buy a laptop that says it's 2.66 GHz triple core, does that mean there are 3 processors each clocked at 2.66 GHz? Or does it mean that there are 3 processors and in total they add up to 2.66 GHz?
Also, is it better to have a 3.0 GHz single core or a 1.5 GHz dual core if you want to run games?

which model pentium 4 has socket LGA775 was implemented.
I mean which model brand hp or compaq or HCL or ibm ? year & model required.
I prefer to buy that model so that i can upgrade to latest processors.

Another question:
Will Pentium 4 with Socket LGA 775 supports any chipset model for upgradation to
1.Core 2 Duo
2.Dual core processors ?
If not pls give me the Chipset models support for the upgradation.

My plan is buy used pentium 4 LGA 775 & upgrade to new processor(only processor using same motherboard of the old one) which eliminates/reduces cost for upgradation.

Is this right plan or is there any complication in upgradation.

A:Pentium 4 lga775 upgrade to Dual core or Core 2 Duo

pathardware first please read this:

The list of processors using LGA 775 are listed on that page. As for your question, YES some P4 motherboards might support Dual Core and Core 2 Duo.

My Current motherboard is an ASUS P5B-MX/WiFi AP and I'm running a P4 Prescott on it. The CPU support list on the ASUS website lists Dual Core, Core 2 Duo and Quad Core support (With BIOS upgrade). My P4 actually was part of a Compaq system purchased way back in 2005. After that the rest of the system (barring monitor and processor) has had major overhauls.

But, as for your plan, I would suggest you go about building an entry level new system by yourself.

I would like to ask you guys if there is a wide difference between Intel Pentium Dual Core T4200 and Core 2 T6400 laptop processors.

My dad recently brought me a new Dell Studio 15 laptop as my high school grad gift. Its equipped with T4200, but as I read in Dell's website T6400 comes as an option. He selected T4200, and now before I set my hands on the new laptop I would like to find out if those processors make much difference in performance and power consumption.


A:Pentium Dual Core T4200 vs.Core 2 T6400

Core 2 Duo is better in my opinion other people might argue they opposite or that they are the same.

I have a dell with Pentium Dual Core and another with Core 2 Duo, same amount of RAM, pretty much the same computer all around. The Core 2 seems to run faster and cooler.

about 2 years ago I have upgraded my computer with a new motherboard, rams and a processor and since we moved in between I cannot find the boxes or bills from that time.

The problem:
I am 90 percent sure, that at the time I wanted a quad core processor and my computer properties say that I have Intel Core i5-3450.
I googled around and all retailers as well as Intel list this processor as quad, but I whenever I use aplications where cores are displayed (i.e. playclaw or some kind of benchmarking), it only ever shows core 0 and core 1.
When I go to task manager > processes > and go to select affinity on a random process, once again only 2 cores are aviable to choose from.

Any ideas what might be causing this? Because if I am not mistaken I have had my computer on a leash for 2 years...

Hi there, I was running Vuze and it became almost impossible to do other tasks so I checked the cpu using Everest and it said one core (no. 2) was running at 24% but the other core was running at 0%. There was no warning sign beside it so I presume nothing is wrong, I just don't get it. Is this normal behaviour? I had Firefox open at the same time so I thought the cores would share the workload?

Firstly, in task manager, there is only one core recognised (one cpu graph). I have no option to select "one graph, multiple cpus".

Secondly, in device manager, there is only 1 core with no option to select 2 or box for detect HAL.

Lastly BIOS doesn't detect more then 1.

I have processor box unchecked and have uninstalled my CPU from device manager in hopes a restard would re-detect it. I have also updated my mobo & vid card drivers from the site and updated my bios to the latest.

I just bought COD: Black Ops for $60 and it requires a dual core processor to play it, anything else I can try short of re-installing windows?

Ok, I'm building a CPU and I'm stuck between Intel's Core 2 Duo E8500 and their Core 2 Quad Q9300. I was going to go for the quad-core, but I heard things about how apps still aren't optimized for four cores. I will mainly be gaming, occasionally using photoshop and flash.

My problem is
a) I want games and apps to run good today
b) I want have a solid CPU that will give me excellent performance for the next 2-3 years.

What's the consensus? I have to go with Intel as I already bought a mobo, and $270 is my absolute price maximum for a processor.

I'm wondering if it is possible or pratical to upgrade the Core i5 processor processor in my Inspiron 17R 7720 to a Core i7? The processor in my computer is a Core i5 [email protected] 2.5GHz; I am seeing multiple Core i7 3630QM SR0UX processors on Ebay for $100 or so. I am not worried about the mechanics of changing the processor, I am confident in my ability to swap one out. I just want to make sure the new processor will fit and work with my existing motherboard. If I do this will the BIOS automatically detect the new processor or are there some software hoops to jump through as well?

A:Upgrade Core i5 to Core i7 in Inspiron 17R 7720?

While the CPU will work, you won't see $100 worth of performance boost from the CPU -- if the system is running  a conventional hard drive, the $100 spent on a solid state drive to replace it will be far more bang for the buck.

i have a Intel E5400 Overclocked to 3.23GHz and was going to upgrade to a Q9400 quad and was wondering as i mainly use my PC for high end gaming is quad core as important as it is used more for multitasking and i was told dual would be better for gaming is this true?

A:What is better for PC gaming Dual Core or Quad Core?

It's a little confusing. I'd say in general, quad-core processors are more powerful than dual core; however, that doesn't necessarily mean faster.

Certain programs are written to take advantage of multi-core processors, like many games and power-hungry programs such as Photoshop.

However, not all are. Windows does its best to distribute the load evenly, but it's not the same.

Furthermore, many quad core processors are clocked at a lower rate than dual core. Your dual-core processor is clocked at 3.23GHz; the quad is clocked at 2.66.

Bottom line: if the programs you will be running can make use of all the cores, you will very likely see a performance increase. If they are not designed that way, there is a good chance your performance will actually decrease.

In your case, I suspect the programs you will be running can make use of the 4 cores well; many games do. But use your judgment!

Because there are two cores on...for instance, my AMD Athlon X2, does that mean that since there are two cores, the normal FSB for one core which would be 2000mhz, would be x2 so i can put in 4 sticks of pc 6400 at 800mhz? or does the FSB not change when you add another core? Also is there somewhere i can learn more about how the cores work together? Im pretty new to the whole concept. Thanks!

A:Dual Core Front Side Bus x2?? or the same as 1 core?

You can only put in RAM that your motherboard supports, and only as much as it supports.

This should get you started in Front Side Bus architecture, and you can like off to other Wiki entries from there.

Also, poking around on will help you pick up a ton of good information, although most it is written assuming you know what all of that means. You should be able to infer lots of new info from their articles and reviews, though.
