4gb DDR2 1066 or 8gb DDR2 800

Q: 4gb DDR2 1066 or 8gb DDR2 800

I just realized I have some extra ram laying around. Here is the question. I was wondering if [email protected] with my AMD 9950 Black Edition OC'ed to 3ghz would be better than [email protected] with my CPU stock at 2.6ghz. I play things like WoW and Battlefield: Bad Company 2. Mostly new stuff.

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: 4gb DDR2 1066 or 8gb DDR2 800

Definitely better off with just 4Gb, and having your CPU OCed than to have 8Gb, and running stock.

The difference probably is minimal anyway.

This is a different scenario if you do alot of photoshopping or RAM intensive stuff, those games won't take up gobs of RAM.

This is the link of my motherboar.......

I want to know whether I can use a DDR3 Graphics card on my DDR2 motherboard and if its certain to work. Please provide detail and whether it'll be compatible.

A:Can a DDR3 graphics card run in a DDR2 Motherboard?

The DDR2 slots on the motherboard refer to the desktop RAM sticks. GDDR3 on a graphics card doesn't make any difference, it's the connector (PCI Express 2.0 probably) that slots into the mobo.

I have a HP dv7-1285dx(Windows 7 64bit) laptop that has 6 gb ddr2 ram in it installed factory. I was considering getting maybe ddr3 (2)4GBs sticks to put in. I mostly use my laptop for video watching(twice, youtube) and ofcourse games.

Is it worth the upgrade?

Why all of a sudden does ram seem to be so expensive?

Any help/advice is appreciated.

I got myself a new mainboard that is based on the ATX DDR3 AMD standard. But I also thought that the old NVIDIA Sparkle (GTX260--896MB) that is based on the DDR2 internal memory set still would work since the connector on the card is PCI-express. Does the DDR2 memory (896MB DDR internal graphics memory) stop the communication with the DDR3 mainboard? Its a bit unfear since this was not the case between DDR1 up to DDR2. Why has there come up such a brickwall between DDR2 and DDR3. Or am I wrong?

A:DDR2 video card on a DDR3 mainboard?

I think you're confusing system RAM with video RAM, they're separate things. What's the model of your motherbaord? If it has a PCI-E slot your GTX 260 should work.

OK! I am a noob at this!
I am running XP Pro 32-bit. I want to replace the Video Card. Nothing great or expensive...just a decent one. It for a friend (senior, that is why XP). I just got him a Dell Vostro 200 slim, added a 1TB HD and installed all drivers and XP. Please let me know 3 things:

1. Does ddr2 or ddr3 matter on the video one better to run on XP
2. 64-bit or 32-bit. I assume 64 will run on 32-bit XP
3. Any suggestions on the card or where to buy (PCI Express 2.0X16)
Thanks! Ynot

A:Does it matter if you use a DDR3 or DDR2 video card?

The only thing you need to know about buying a single graphics card:

Do I have a large enough power supply for this card?
Do I have the appropriate card slot for this card?
If the card is 2 (or 3) card slots wide do I have room in my case?
What monitor cable connector will I be using?

Everything else may be important for choosing the card you want but not needed to get the card working.

1) Graphics card memory type is irrelevant as far as the operating system is concerned.
2) I'm not sure why you are asking the second question.
3) We need to know what you will be using the card for. (A slim form factor doesn't give much options)

You can't just pick and choose the memory type you want. The memory type must match the design called for by the motherboard. DDR3 is the latest memory design and DDR4 will probably be available before long.

The only way my PC let's me run it on 1066speed and 5-5-5-15 timings all day with no problems is if I let it first run to Window with the 800 speed an then restart it and change the speed and timing in the Bios.

A:Another gig of DDR2 or upgrade to DDR3?

Unless you are running a 64bit version of Windows you won't be able to address the full 4 gig of memory. That aside, don't believe it's really worth investing in another motherboard for socket 775 as it is coming to the end of it's life cycle. Might want to consider upgrading a core component like your graphics card that could be carried over to your next system.

Hi Guys,

Just a quick question... the differerence between DDR 1,2 and 3.... in terms of pin placement on the motherboard? and am i correct in saying there is no motherboard that supports 2 different types of RAM? also... i wanted to find out the different speeds of RAM eg: 400MHZ,660MHZ 1333MHZ etc.. does that change the compatibility with the motherboard? For example, DDR2 400MHZ is installed can you insert DDR2 800MHZ and it will work? and if so will it work together with the 400 or must you have the same speed with all your RAM?

A:Difference between DDR, DDR2 and DDR3

There is no reason to post two identical threads.

DDR1 is 184 pin, while DDR2 and DDR3 are both 240 pin, so some motherboards support both DDR2 and DDR3.
If the speed is not supported by the motherboard, it will revert to the highest supported speed.
All RAM will run at the speed of the slowest module. In theory, it should work; I wouldn't count on it.

So, this is my problem, I set it in the BIOS to utilize this RAM at 1066 at 7-7-7-20/2.0V according the Corsair's specs, but when I run Memtest I get tens of thousands of errors within a few minutes. Memtest on the other hand is picking it up at 7-5-4-8-32 also, the things I'm setting are the CL-tRCD-tRP-tRAS, I believe those are the right things to set.

Any Idea's here guys?

A:Getting my Corsair XMS2 to DDR2-1066

If Memtest is picking up errors, one or both RAM modules would seem to be defective. If they are a matched set, you probably should RMA them both.

By the way, in trying to do some research on your Biostar motherboard, I discovered your CPU was not supported by your motherboard even though it evidently works. I don't know if this is in any way related to your problem. See this CPU support list: Biostar.

Hi all,

I currently have 3Gb of DDR2 memory, in 2 slots (1x 1GB, 1x 2GB) - however i wanted to increase this to 4GB or even 6GB. Basically i was wondering if the following factors would affect my choice:

1-Is there a limit of how much RAM i can have in my motherboard?
2-Can i cross between DDR3 and DDR2 memory in the two slots, or do i have to keep the same type in each? - (and also, whats the difference between the two)

Thank You

If your motherboard currently supports DDR2, then you can only add DDR2. They're not slot compatible.

A:DDR2 RAM voltage and OC

Hi wert56boom
if you are OC'ing via an FSB push, the weak link can be any component or chipset. the fact that you have mis-matched ram modules could be a likely suspect. is you are at 2.1 now...I would stop just shy of guaranteeing you that 2.3 will not give you stability, and probably burn up your ram. A few of the high performance brands have an overvolt guarantee up to 2.1v Take what it will give you @ 1.9v and call it good unless you are prepared to replace it.
I would try removing the lone Transcend module and see if that yields better results. you will lose 1 Gb fd ram, but gain dual channel until you get different memory. and it will let you know if the mixed modules are the limiting factor. The 880-890 Mhz you are referring to is the effective DDR rating 2x400Mhz = 800Mhz DDR2

A:DDR2-800 vs DDR2-1066

Actually selecting between 800 and 1066 RAM in the same brand doesn't present to terrible price penalty.

For 5 bucks more I'd go with the DDR2 1066. That's whether I could tell the difference or not.

Truth is, DDR2 10666 generally runs @ 2.0 volts or better, if you set the BIOS @ 1.8 (the generic DDR2 voltage), it's liable to default to 800Mhz anyway.

There are no DDR graphics cards made anymore-not since about 2000-2001.
If your AGP slot is x4 or x8 you will be fine with the card if it's within your budget- the only compatibility problem you would run into is if your AGP slot is generation 1 ( i.e AGP 1x or AGP 2x) as these use 3.3volt signalling. Your computer would most likely have to be 1998 vintage for it to have that.

Hey Mose,
you will not notice a performance difference between DDR2 and DDR3 for the purposes you stated, so 4 gb of the DDR2 make sense. and if you are going to upgrade in three years then you will undoubtedly be building or buying a new system anyway, so the DDR3 you would purchase now would have no place in an upgrade three years from now anyway.

Yes the DDR2 modules and the DDR3 modules both have 240 pins. The keyways are in different locations so you can only install DDR3 modules in a DDR3 motherboard. DDR's highest speed is 400MHz. DDR2's highest speed is 800MHz. DDR3 highest speed is 1000MHz

I have a problem with my computer... first, here is my pc:

AMD Phenom x4 9600 Processor
2X2GB A-DATA VITESTA Extreme 1066

The ram is new.. i used to have 1x2GB Kingston @667Mhz and everything worked fine.
When I changed the RAM, i started getting random blue screens and crashes.
Windows only detects 3.25GB of RAM. But i already read why that happens.

I tried removing 1 stick of RAM and i haven't got any blue screens but games just randomly crash.
I don't know if there is any other info i should provide.
Can anyone help me with this?

A:8600GT DDR2 vs 8600GT DDR3 vs Sapphire Hd 3850

DDR3, here's more info, stands for "double data rate."
Ok, here's how I see it, I may be wrong. Ok, DDR is the transfer of data correct, well DDR3 would transfer 3 times the data than the DDR(with the invisible 1 after).

Also about crysis, I'm not to sure about the performance of that card, but it will run HOT on medium... Try the very low or low setting or you better get some cooling ready.

EDIT: I've looked around on the web and found that crysis alone uses like 1 GB of memory on medium setting, that excludes other programs.

Running Corsair DDR3 1066 memory on an Intel DX38BT board. Very glitchy, problem being that occasionally I turn on the box and get the three beep error code "no memory". The memory came bundled from Tiger Direct with the motherboard and a Q6600 processor. I assumed the memory was compatible. Default on the motherboard is 1.5V. For some reason, I think the memory is 1.7V. The BIOS gives me the abilty to reset the voltage, have used the default and the 1.7V settings and still get the beep codes from time to time. I did a search and cannot now find the specification for the voltage for this memory. Checked the Corsair website but very little informaion available. The Corsair memory does not appear on the Intel tested memory list. Does anyone know the voltage on this Corsair memory?

Im just curious, has anyone ever pushed their DDR2 RAM to 1333?

Also is it better to have, say, 1200 and latencies of 5-5-5-15 or 1600 and 6-6-6-18?

I know that was short but i have nothing else to really say.

A:Has anyone pushed DDR2 to 1333 or comes 1333 stock?

It is reported that there are some applications where lower RAM timings would be more beneficial, but seriously, like what Zenosincks said, running your RAM at 1600mhz and higher timings would be much better.

Btw, I won't be able to tell you in what situations that would be better. I just read it somewhere, and there's that. Don't quote me on that.

About pusing the RAM to that speeds, I think I might have surpassed it. I haven't quite got to 1600mhz, but I think I've got 1540 or thereabouts (slightly lower if I recall).

However, I throttled it back somewhat, I can't remember why. Probably because it wasn't 100% stable.

I have an Asus P5W64-WS board. It runs the 975X chipset. I have upgraded to the latest BIOS and installed an Intel E6850. All is well, and not unexpectedly my temps have dropped about 8 degrees centigrade. My bus speed is reported as 333, FSB as 1333, and my multiplier as 9. My question is, what is the optimal DDR2 memory speed that I should pair with this processor? I am not going to overclock or game, so I am not as concerned about latency or tweaking, I just want to know what the optimal memory speed would be to match the FSB, etc. This computer is used as a trading workstation, so stability trumps wringing the last bit of speed out of the the system.

Thanks for any suggestions.

But I am trying to figure out if that would be the best buy for me. I do lots of gaming and downloading. I want the Ram for the games and for Vista. The Egg has it listed at $337 for 4GB. But I have also read many people say if you get 4Gb to try and get 2 X 2GB. But the dominator only offers it in 4 X 1GB. I do plan on overclocking. So should I get the 4 X 1GB of the Corsair dominator or something else? I have a Maximus Formula motherboard.

Im throwing together a machine for my GF.. I have a processor but need to get a socket 478 mobo.. The one I was looking at uses DDR2-400 memory and I have some DDR2-800 memory sticks laying around..

Will it work ok to use the DDR2-800 sticks on a mobo that accepts DDR2-400 memory?

A:Ok to put DDR2-800 memory on a DDR2-400 mobo?

"Typically" you can run faster memory in a machine rated for slower memory - the memory simply runs ate the mobo spec. That said, memory issues are always subjective to the varying tolerances of the memory itself and the motherboard.

I just combined 333 and 266 rated memory in a laptop that's spec'd at 266 - it flies with no issues.

I think you'll have no problems.

Just make double-sure that all the other specs are identical such as voltage, both unbuffered, both unregistered, same latency/speed specs e.g. 2-5-5-5, hopefully both with or both without SPD (or maybe all memory come with an SPD these days?).

Try to run it with the memory, it won't cause any damage. If you start getting errors/crashes, you know it doesn't work.

From the newegg comments:

I feel as like I should clear up the confusion about this memory. This ram is programed to default to DDR2-667 at 1.8volts instead of the DDR2-800 at 2volts. This is because most motherboards default to 1.8v, and it would suck if you were trying to build a new computer and you couldn't boot because your memory only ran at 2v. That's why kingston made it so you can run it at 1.8v(although at a slower speed) and change it to 2v later. YOU NEED TO MANUALLY SET THE VOLTAGE TO 2VOLTS AND SPEED TO DDR2 800 @ 4-4-4-12 IN THE BIOS. If you don't do this then you are wasting good memory. If you don't believe me then read the data sheet here: to expand...

So that makes sense...

yes any system can handle a new videocard just depends on your motherboards compatibility also do you know what the wattage is on your power supply (incase if you dont know a powersupply is the box were u plug u power cable to at the back of your computer.

second question :Will I notice any significant graphics/speed difference if I were to upgrade, assuming my system only has an AGP4X compatible slot? What if it has an 8X slot? yes you will notice a difrence because the x1300 pro is a newer card then the Geforce 2.

What's the approximate value of a used Radeon card?
i would personaly say $50 CAN or roughly $40 US (still cant belive things arent cheaper in canada even with the CAN dollar being higher then the US)

In your opinion, is it worth it to upgrade?

Thankful for any useful tips

A:DDR or DDR2 and other questions about RAM

Im not sure if the amazing people here at techspot can answer this without knowing what your motherboard is. I AM NOT AN EXPERT, I KNOW LITTLE OF MEMORY, but I will try to answer these questions.

1. I can't very well use DDR2 or can I/should I?

Depending on what your motherboard suports you should be able to use DDR2. DDR3 Is new in the market but still costs a lot, and your motherboard may not suport it so I would stick with DDR2 unless you have a couple hundred to spare.

2. Should whatever memory I buy have the same CAS latency and frequency?

I dont think It has to be the same but I would recommend not switching it up to much becuase of errors that may start occuring, buying a pack of ither 2x 1GB or 2GB would probably be best.

3. Should I buy a 1Gb and keep my 2 512's or should I buy 1 2Gb or 2x1Gb?

Im not sure if this has any effect on performance but as long as you have a total of 2 GB I dont think it matters, but I would either try to keep my slots free and go with the 2 GB stick, or spare the memory you already have and add on 1 GB. I would just be aware that If you keep the 2x 512's and buy a new 1 GB stick there might be errors due to the differences.

Again dont make and major dessicions baced on my responce because for all I know everything I've just said is completely wrong.

Anyway hope this helps.

A:different fsb of ddr2 ram

Hello and welcome to Techspot.

It`s not considered to be a good idea to mix ram speeds, as it can cause stability issues on some systems. However, there`s nothing to stop you from trying. Please be aware that the faster ram will automatically be downclocked to the speed of the slower ram.

Hi there. I'm not quite sure what you are asking in your first question.

Virtual memory is exactly that, its not actual RAM memory (DDR & DDR2 etc) it is a section of your harddisk that your OS will use as make-shift memory when you have insufficient RAM memory. This in turn means that it is slower and doesn't perform as well as normal memory, due to your harddisk being much slower write/read than RAM memory.

So, in conclusion, RAM memory > virtual memory, however if you don't have enough RAM memory then you can edit how much virtual memory you would like to have (at least in windows you can, although not sure about Vista).

Q: Ddr2

Hi, lately i have been hearing that the DDR2 RAM has been becoming standard...Can someone explain to me why? I always though that DDR4 was the more advance ones.


i think you're being confused with DDr4 with ddr 400. DDR400 is basically ddr. With 2700 and 3200 version etc...

DDR2 is faster.

Hey guys, i was just wondering what if I bought a Motherboard that takes DDR2 800 or whatever but slapped on a PC3200 Ram, would that mobo read my ram? Will there be conflicts?

Also I was thinking of building a new PC and was wondering what is better. A E6400 or AMDs 5600?

Thanks in advance

A:DDR2 Motherboards compatible with a PC3200 Ram?

First, you cannot use DDR1 RAM on a DDR2 motherboard. Just won't work. If it does, why bother make a motherboard with slots for both RAM? (sorry no link, but I've seen them before).

Also, the E6400 is definately way more powerful than ALMOST any AMD CPU out there at the moment, and definately more powerful than the 5600+.

A:Using DDR and DDR2 Memories simultaneously

Ralphmex said:

The risk is it simply won't work.
If I remember correctly, all motherboards that support both DDR and DDR2 will only work when using one or the other -- never both.
Asus emphasizes the warning not to use both types of memory simultaneously because it simply will not work. It is never recommended to mix different speeds of memory for any given system, so the possibility of mixing two generations of DDR-RAM (and for it to work) would be highly unlikely.

The good thing about these types of motherboards is they provide support for multiple types of memory modules. The bad thing is you only have two DIMM slots to use at any given time, and must remove other older memory modules before installing new, (maybe larger) ones.

If you want a memory upgrade, chances are you'll have to remove your current 2x512MB of DDR memory. After that, I would recommend getting 2x1GB DDR2 modules, a superb upgrade from what you currently have (both in terms of speed and amount).

to run dual channel do I have to have my sticks in slots 1 and 3? Right now I have my sticks in 1 and 2 right next to each other. They still register as 2 gigs

A:ddr2 ram

In most cases, you need memory in the same-colored slots in order to ensure dual-channel mode. If it's a newer Asus, chances are you have two yellow slots and two black slots. Make sure you have dual-sticks (same size) in the same color slots for dual-channel.

The best way to tell without opening the case is to download/run CPU-Z and check the "Channels #" for Dual. If it's not Dual, then you can swap your memory around to get this working.

I need to buy memory for a ECS P4M800PRO-M v2 motherboard with a Pentium D 805 CPU. This system normally runs a 133 MHz bus clock giving specified 533 MHz memory speed.

However, I am planning to experiment with overclocking, so thinking to buy 667MHz (PC2-5300) or even 800MHz (PC2-6400) memory.

My question is, will this faster memory work at the normal 533 MHz speed, in case the overclocking does not work...?

Has anybody run a system with faster memory than specified... or have any comments...?


A:DDR2 Memory -- faster = better?

this should work; the memory will just run at the slower speed.

Make sure you buy high quality memory. Check the recommended memory list for the mobo, and buy sticks that closely resemble the recommended ones if you're buying faster ram.

Okay I'm a noob, we all know this. When I buy ram and it says ddr 1000 or 1200 is this the native speed that it runs at from factory. Is the concept same a cpu's as you buy a cpu that runs at 800fsb or 533fsb or w/e. Then you change the fsb through bios etc? Same concept right? I was wondering if I bought pc 10000 ddr2 would I be able to run it in a mobo that stats 6400 is the highest I can run. So is it more so dependent on the ram or the mobo?

Now your problem is which RAM to buy? What does that MOBO say for you to buy? Look in your manual it should tell you, but better yet go to the MOBO and see what you can buy?

Hello all.

This is my first post here, and thank you for the opportunity to do so.
I hope this was not asked before:

I bought an Asus P5N32-SLI Deluxe mobo. It states that it supports 667/533 DDR2 memory.
I can get 2x 1GB 800MHz on special in my country {Patriot}.

Now, question one:
I need {and I mean REALLY} to know, will my board support them, and if it does, will it just downgrade the speed to 667? I have an idea it might.

Question two:
If it supports it, and downgrades the speed, will it still run dual channel?

Can anyone give me an idea to one/both of my questions? I woulds really really appreciate it.

A:Installing DDR2 on my mobo

DDR2 800 modules are backwards compatible with slower motherboards. the ram will work, but it will run at the slower DDR2 667 spec. you would, however be paying a higher price for the DDR2 800 modules than you would for DDR2 667. your motherboard will run two DDR2 sticks in dual-channel mode, provided that they are installed in accordance with the manual's specifications for dual-channel operation.

A:Will DDR 400 RAM work in a DDR2 800 standard motherboard?

Welcome to Techspot!

It won't work @ all, because DDR400 RAM has 184 pins, and DDR2 RAM has 240 pins, and uses less voltage than DDR.

After asking a few questions last year in this forum I figured that there was somthing up with my motherboard (hdds come up as removable media, wont boot from cd, BSOD when add 2nd hdd) and still havent got round to replacing it.

Now the system has stopped recognising the mouse or any other USB devices so I have motivation to do somthing about it (might not be related but I wanna get it all fixed so i thought id start with mobo)

The only thought that occured to me was when I read that most DDR2-800 was overclocked 667Mhz, so should I try increasing the voltage on the RAM slightly and see if the system becomes more stable (less blue screens etc) before i go buying a new mobo??? Or is it designed to still run fine at 1.8v???


Edit: Memtest has shown no problems with RAM

A:RAM voltages for DDR2-800

If memtest runs fin then raising the memory voltage shouldn't change anything. If you want to be sure, look for the specifications of your memory modules & see what voltage they're supposed to be running on.

The x1300 is a little faster, so I'd recommend it more. I have a pci 6200 128mb, which I got before the x1300 came out, and it isn't too bad considering it's a pci card.

Okay, i just wanted to double check that im a noob.

I have a Asus p5b, with core duo e6600 and patriot 1ghz ram. the ram is currently running at 800mhz or somthing, and everything is stock. timings are the factory settings on the ram.

I think that means i should oc the cpu and ram to be

6x500 and ddr2 1000 but i dont know. i want the ram to runat the ghz, and i would like some oc on the cpu, as i've got a big typhoon 120mm sink on it, keepin it chilled.

thanks for the impunt~!~!~

A:OC E6600, Asus P5B, Patriot ddr2-1067

the core2's o/c great, but i doubt your memory will be able to keep up. increase the FSB clock in small increments, verifying that the system is fully functional after each increase. before long, you will get to a point where the system crashes upon boot or will not POST. you may need to reset the BIOS, so make sure you know how to do that and that you write down your settings. once this happens, revert to the last clock speed that worked. run memtest to ensure that the system is really functioning properly.

in addition to increasing the clocks speeds, voltages can be increased to allow for higher speeds. increasing voltages will cause a lot of extra heat to be produced, and a dramatic increase can damage/destroy parts. i wouldn't mess with the voltage until the system has stayed running for a few days with a maxed-out FSB. leaving the voltages alone is a good idea for novice overclockers.

overclocking can irreparably damage and/or destroy your hardware if done wrong, so it's important to be patient. remember that you are going to need to keep close tabs on your CPU and northbridge temps during the entire process. if you see temps that exceed the mobo's specs, back off. even if the system seems to be running fine, heat will, in time, kill it.

it would not hurt to consult some online literature on overclocking and to familiarize yourself with your mobo's manual and BIOS.

I am considering buying the new Macbook Pro Core 2 Duo that was announced a couple of days ago. One of the configurable options is to load it up with max DDR2 RAM of 3 GIG in 1x2Gig and 1x1Gig arrangement.

I heard about the dual channel memory benefit of accessing in full 128 bit mode when the RAM are installed in pairs.

So my question is if I upgrade to the above configuration, would that wipe out the benefit of 128 bit access?

Thanks very much.

Yes it would. Get 2GB in a 1GBx2 configuration i.e. one 1GB stick in each slot and it will enable u to use dual-channel mode for increased performance.
