Speed the USB flash memory up

Q: Speed the USB flash memory up

Hello guys,

I have an USB flash memory brand PNY. Its speed is very low, that is, when I copy or delete files into/from it, it takes a very long time to be done. Is there a way to speed it up?

Preferred Solution: Speed the USB flash memory up

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.)

NO. Most likely you have it inserted to a USB 1.1 slot when it needs USB 2.0.

A:speed the USB flash memory up

Well if you're using USB 2.0 with it, it's naturally pretty slow these days. I would just say use USB 3.0 when copying or moving files to it.

I have a motherboard that has a FSB of up to 400MHz.
My processor is an AthlonXP 2200 which can only run at 266MHz
My memory is 256MB DDR DRAM PC2700
SisSoftware Sandra testing tells me my memory speed and processsor speed do not match. Question is: Does this really matter? I know a processor upgrade would sort it but a)the computer seems to run fine and b) I daren't try to sneak ANOTHER pc purchase past the wife! (just yet);-)

I know the question is awkward. So hopefully, I can explain it.

Say that I have a 500 GB external hard drive. But as it turns out, there's only 465 GB according to it and my computer. Why isn't there 500 Gb, but rather only 465? This also applies to mp3 players like iPods.

Why is this?

Can I do something to get back the "hidden" memory?

Obviously higher is better, which is more important? Would a card with less memory (64MB) and higher speeds run better than a card with more memory (128 or 256MB) and lower speeds? If speeds are = then a card with more memor would work better, correct?

I've been looking at the Surface Pro and other tablet/laptop convertible machines fitted with Win 8. The top-end models usually offer only flash memory in stead of a hard drive. The standard 128 GB flash memory available seems hopelessly inadequate for storing Win 8, a full range of programs and a decent amount of data. Most of these thin, expensive models have only one or two USB ports available. Where must the necessary memory come from? Must an external hard drive be carried along? Nothing wears a USB port out more quickly than a fairly heavy external device such as a hard drive dangling from it in mobile situations.

A:Lack of needed memory on flash memory Win 8 machines

You can add extra storage with SD cards on some of them. It's not ideal but better than nothing I guess.

I want to upgrade the memory of one of the pc's in our house. I get low memory alerts often and I can't delete much else to create room. I have never opened up a pc before, and I don't want to screw up and make things worse. The pc in question is a HP Pavilion a1150Y with a Intel Pentium 4 (3.00 GHz). OS is Windows XP SP2. It came with 512MB RAM and I would like to go up 2GB. I went to, ran the system scan, and it says that this type of memory can go into that pc: "DDRII memory with support for DDR2 PC2-4200,DDR2 PC2-5300,DDR2 PC2-6400,DDR2 PC2-8500 speeds." I don't know what speed I should be installing. Any help would be greatly appreciated.

I have a Corsair Flash Voyager pen drive that I installed the W7 setup files on, before my DVDs arrived. I used it to install the RTM on my primary rig, and just a couple of days ago, I tried using it again on my secondary rig, but both times the screen where is says that it is loading Windows files moved like a sick snail across the screen. I thought that it would be faster than the DVD, but that definitely is not the case. I'm going to delete the files on it, to use it for general purposes, but it's performance has me wondering if there is something wrong with the drive, or if it's behavior is typical?

Is there any way to o boost the transfer speed of a 4GB i-ways Flash Drive ? Are there any utilities out there coz it takes me forever to copy small files in big quantities to it .. plz help !!!!

A:Usb Flash Speed Booster !

Sorry, but no. You can sometimes find that one USB port will be significantly faster than others. Do not connect other USB devices when you are scrambling for extra speed.
The fast ones are now getting down to very low pricees... See,,,, and others...
There is not way to speed up older technology, but the new ones are very speedy if you shop carefully.
The best ones have a five year waranty, and list speeds of 100X to 200X. These numbers translate to Read 6 GB/Sec, Write 3 GB/Sec on up to read 30 GB/Sec, and write 30 GB/Sec
When SPECS do not post speeds, warranty, etc., they are likely NOT fast.

The top ones will likely say VISTA ready, and have a five year warranty as well.
One good model is IronKey, others are OCZ, Corsair, and so on. There will be more postings soon as they are waiting until after graduation as they try to rid their excess stock of the unreliable and slow USB drives..

Hi all. I just bought a 1GB USB 2.0 hi speed flash drive to use as a Readyboost device. When I plugged it in, Vista auto install the driver for it (

The problem is that it Vista recognized it as USB 1.1 even though I have USB 2.0 support for my computer and I all of my other USB 2.0 devices work perfectly and another device I have (a mp3 player which is USB 2.0 complaint) works fine and operates at hi speed. I tried formating the drive, plugging it into other ports, uninstalling and reinstalling the driver, but nothing seems to work. I used SiSoftware Sandra 2007 to check the current operating speeds of the devices. I know I have USB 2.0 ports install in my system and enabled as I said before my other USB 2.0 devices operate perfectly. Help much appreciated.

I read reviews (mostly on Newegg) regarding USB Flash Drives and the reviewer will talk about the Read/Write speeds they experience with their USB drives.
How do they find out the Read/Write speeds of those drives?
Can you find that in Windows, or do you need to download separate software?

A:Determining Read/Write Speed of USB Flash Drives

There's many transfer speed benchmark tools out there. If you're lazy, you can do it the old-fashioned way. Get a BIG file. Then copy and paste and time it yourself. Then divide the file size by the time it took. Note that you're supposed to look at the light on the flash drive (some blink) to check when the transfer ends - not when Windows tells you so, because writes usually use a buffer, and although all the data has been copied from your HD, it may not have been copied from the buffer to the flash drive yet. Another thing to be careful is to do the write, but NOT do the read from the same drive again right after that. The reason is if you have a lot of memory, the data will be cached in memory, and read from there (as opposed to the flash drive) when you're copying back from the flash drive to the HD, totally invalidating your results. I don't know of how to manually flush memory cache besides rebooting and doing the read transfer speed separately.
For automated tools, google for flash drive benchmark

Iam trying to work out which speed stick to buy to boost the ram in my sisters laptop from 3Gb to 4Gb so she has 4Gb and better speed through dual-channel running properly

I THINK CPU-Z is mis-reporting the speeds, timings and type due to the way its working with 'symetric dual channel mode' with a 1Gb stick and a 2Gb stick

both sticks are reported as PC 10700 (667mHz) (yes that's 10700, not 10600)

but the running speed of the memory is 533Mhz and the operable speeds are:
457 533 609 685
ive never heard of such 'odd' speeds like 457, 609 and 685Mhz...

timings on 685 are 9-9-9-25

Crucial System Scanner says they are PC 8500 sticks?

Am I right in saying they are PC 10600 sticks and everything is mis-reported due to the mis-matched modules running at slower speeds?

should I buy a PC-10600 2Gb stick to replace the 1Gb stick?

Intel says the memory speed for the 3930k and the 3970x are both DDR3-1066/1333/1600.

In order to reap the full benefit of 1866, must the CPU be overclocked? If so, is it proportionate, so 15% overclock?

A:Memory Speed?

I would suggest taking the case off the computer and making sure that all components are reseated correctly. It could be that while you were removing and reseating the RAM a component was jiggled and is not making the proper contact. Also, did you ground yourself while removing the RAM? A wrist strap is good for this, or at least making contact with the chassis before going inside.

I went to the memory supplier website and it lists the memory that i bought as PC3200/400 mz. Thanks!

A:Memory speed

First question, what speed is the ram that was in there originally? If the original 1Gb of ram is PC2700 ram, your motherboard will automatically underclock the new ram in order to match the old.

If your old ram is also PC3200 ram, then please give us your full system specs (motherboard make/model in specific)

Hello from Greece! I own a G 50 30 / 80 g 0  my question is why cpu z is only showing memory speed at 666mhz can i change it in bios?  Thanks!

A:G 50 30 memory speed

Hi Dpota,
Welcome to Lenovo Forums.
1333 MHz is the effective clock rate. DDR means double data rate, data is transferred on both the rising and falling edges of each clock making 666 MHz effectively the same as 1333. CPU-Z is showing you the actual clock rate. That's perfectly normal you have nothing to worry about and the RAM is working correctly at the right speed.
(666MHz) 9-9-9-24 is the delay between certain memory operations (measured in clocks). Lower numbers are better, but they are also relative to clock rate. 9-9-9-24 is a little slow for 1333 MHz, but you should not try changing it as it can lead to system instability.
Let us know how you get on.

Hey guys,

Just looking for some quick advice... am putting together a piece-meal system from some spare parts and I noticed that our local CompUSA is running a special on memory... I was planning on purchasing a 512MB DIMM of PC3200 for ~ $100. BUT, they have a special going on 512MB DIMM's of PC2700 for less than $40 after rebate. Just curious as to how much difference would be noticeable between 512MB of PC3200 or 1GB of PC2700.

I do plan to do my fair share of transferring videos from my digital camcorder with this machine, so there will be some video editing and processing involved (which inclines me toward the faster memory). However, I'm doubting that the speed difference will be noticeable by dropping to PC2700 and doubling the amount of RAM (and for less $$ than the single PC3200 DIMM). Thoughts?

Re. a Duron Mainboard K7S5A - (Win 2k)

I have been discussing with a friend the upgrading of memory on my new Duron Mainboard - She wonders about the following, and says:

It depends whether we can take DDR-266, which runs then at 133mhz, and run it at 100.

The duron runs the memory at 100, but if you wanted to upgrade to an athlon later, you would need to run it at 133.

100 mhz memory cannot run at 133. We need to find out if 133 memory will run at 100.

Does anybody know, please? Thank you for any advice you may be able to give.

Hi All,

I currently have 3 DIMMS installed and wasn't aware till recently that the originally was 100Mhz and the two I added later were 133MHz.

The CLK speed is set to 100MHz and I've not had any problems but when the original 100MHz DIMM became unseated my BIOS recommended changing the clock speed to 133 (I hadn't immediately noticed the loss of memory!).

My question is, if I add more memory at say 400Mhz will this give me any problems?

Do you just set the clock speed to the lowest DIMM speed?

I don't really know what 'dual-interleaved' means and I read somewhere about it doubling the stock speed of the RAM or something. Anyway, does this mean that the speed of the memory is actually1066MHz or 533MHz? Bizarrely, the modules he's got installed are 667MHz so I'm curious as to what the speeds really are.

ok i have 3 sticks of ddr3 memory each stick is 2gb... my question is two of them are faster then the 3rd one.. would removing the slower stick and just using the two faster sticks give me better system performance then have 6gb with a slower reading... hope i make sense.....

this is what i have for ram... in my system right now
slot 1: PC3-12800 (800 MHZ)
slot 2: PC3-12800 (800 MHZ)
Slot 4: PC3-8500f (533 MHZ)

A:Question about Memory speed in my pc

For sure since the two faster sticks will have to downclock to match the slower stick. Better yet, buy another 2 GB of the faster stick for optimum performance.

I have an olympus camera. I use an xd or sd card and understand the sizes eg 1 mb etc. But think that some cards are faster so you can take your pictures in quick succession. How does one know how fast cards are?

I just finished building my new christmas pc . It runs great, but the only problem is that my memory is supposed to be DDR3 1600, but when I boot my pc on the black screen ( BIOS post? Something like that ) it says something like DRAM 800. My Motherboard supports up to DDR3 1333.

So my question is, how do I overclock this memory to 1333?
On the stickers on the side of the sticks it says 9-9-9 @ 1.65v, which is the latency I think.

This is my memory.

A:Wrong Memory speed

Download and run CPU-Z and go to the "memory" tab. (this is a handy app to have anyway)

Make sure the memory is in "dual channel" mode and if it's 800Mhz dual channel, you have 1600Mhz RAM.

You can also go into the BIOS...if you built the computer, you will know how to get into the BIOS. There will be memory configuration options there. Make sure you are at the right speed and voltage.

However, your POST screen "should" be showing 1600Mhz. Most POST screens I have seen tell you the actual speed. You could try using the "pause-break" key to stop the POST so you can have a look at it. Use the "print-scrn" button to continue with the POST.

I have an AMD dual core Opteron with 2.5G of DDR3200 memory, which runs at 400Mhz. If I jump to 3G or more, the speed drops to 333Mhz. I am still running WinXPMCE and am perfectly satisfied with it and no BIOS upgrade is available. My question is: Is the tradeoff between more memory at a slower speed worth it?

which stick will perform faster?

The PC3200 is the faster but if your MB doesn't support it - ie. if it only goes as high as PC2700 then the faster mem would do you no good really.

Just a curious question;

I ran winsat mem a couple of weeks ago and got a 13600+ read.

Ran it today and got 15985 read.

Only system change was adding a Radeon 6670 Video card.

Does memory speed change this much ? What might cause the disparity ?

A:Memory Assessment Speed

I assume prior to the HD 6670 you were using the onboard video, if so that would be where the difference comes from. The onboard video shares/gets it memory from the system memory (up to 512 MB), and it got freed up when you added the video card.

I got the same thing if I enabled the onboard video on my old computer (used for a third monitor). The WEI memory score was/is higher when the onboard is enabled and lower with it disabled.

I just need clarification, I have this Motherboard, currently I have PC2100 266 mhz (256 mb). The board says it has a bus speed of 400 mhz, so dies that mean I can use pc3200 400 mhz (1024 mb) memory (I would remove the 266)?
If so what is better keep the 256 mb + the 1024 = 1280 @ 266 mhz

Or just go with the 1024 @ 400 mhz (removing the 266 mhz)

The main thing I am intersetied in knowing is if the BUS speed is related to the memory speed

I did read this, but it didn't really explain things for me

It says effective speed is double core speed, which would make my effective speed 1066 if the frequency listed by black box were "core". But it's supposed to be 1600mhz

Corsairs C7D ram is advertised, and sold as 7:7:7:20. Black box reports it as 8:8:8:20?

A:CPU - Memory - Speed Matching?

you could use any speed memory your board can take with any speed processor your motherboard can take. although if the bus speed of the memory is slower than the processor bus your processor will be underclocked to match the memory, the board might run them out of sync, or you will need to overclock the memory(which i am not recommending) to match the processor bus. if the memory speed is faster than the processor bus it will be underclocked to match the processor. your best be is to get the DDR 333 or the DDR 400.

I am using computers for the last 20 years and know some basics about the hardware & PC operations, I am planning for a new higher end P4 PC with All in wonder graphics card & LIVE wire sound with speakers and all,
I need to clarify
1. should the processor & mother board speed be same?,
2. If I choose a RAM with (speed ?) of 333MHZ and use a mother board with 800MHZ, Is it a mismatch or underrating the board capabilities?.
4. To simplify my question what are the difference in using a
a.) 533MHZ processor / 533MHZ board with 400MHZ RAM
b.) 800MHZ processor / 533 MHZ board with 333 MHZ RAM.
c.) 800MHZ processor / 800 MHZ board with 400MHZ RAM


A:CPU, Mainboard & Memory speed

1) I'm not really sure what you mean by motherboard speed, its more about what processor your board will support. As long as your board supports the processor your looking at your good to go. I suppose its possible that a board won't be able to support certain special features of the processor if there are any, so its best to read the specs of the processor and board to make sure their compatible.

2) Again its really a matter of the board supporting a certain speed of memory. Usually boards will have a few configurations of memory they support, just make sure the memory you want is supported by the board.

4) b, I think means the board will not support the processor, a and c should both work fine but c will have faster througput performance.

If you find the exact brand and make of motherboard and processor your intrested in you can usually get a nice manual from the manufacturer's website. Just make sure everything is compatible before you buy it and you will be ok.

They are running at actual clocks of 400, = effective clocks of 800. (DDR2 800. Close to what you're supposed to run at) You will most propably need to go to BIOS, up the VDIMM to what the RAM's specs say and then put the frequencies and latencies to what they're supposed to be.

A:How do I test memory speed?

I found another thread on TechSpot that mentioned the utility I was looking for, it's called CPU-Z and I highly recommend to determine what your system can handle for RAM, etc. Now my question is, what is the maximum speed latency my system can handle? My CPU has bus speed of 100 MHz with Rated FSB speed of 400.0 MHz. So that means the fastest this CPU can handle is approximately PC2100 without any wasted bandwidth?

My system can't handle dual-channel BTW. Since it is non-dual channel will the increased bandwidth of my current memory (400 or PC3200) help in this regard? Thank you all for reading my post.

Hi, came across this forum yesterday and though I'd move in

It's been a while since I've assembled my own PC but that's what I'm doing now and have a couple of questions..

I have a Gigabyte GA-8AENXP-D motherboard (which supports a FSB of 533, 800 and 1066Mhz) - as I've bought a Pentium 4 640 (3.2Ghz which is a 800Mhz FSB Processor) what speed memory should I use?

I was told by someone that 533 (4300) would be okay - is this correct?

The main reason for doubt is that the manual says "to use a DDR2 600 memory module you must install a 800Mhz processor and overclock the BIOS"..

Can anyone clarify the most stable speed of memory to use and also tell me advise me on CAS Latency?

Friends this has nothing to do with which os, to my understanding, but I posted this on lesser forums and stumped everyone. I predict that will not happen on this forum!

In theory my 'project' notebook, having i945GM chipset, is supposed to run the memory bus at either/or 266MHz or 333MHz. I have the two slots populated with matched 1GB 667MHz ddr.
When I pull up SIW to check, it says "DRAM Frequency 266.0"
It shows the modules themselves as "667 MHz"

So I go run MEMTEST 4.0, and it shows:

RAM Speed = 221MHz [DDR445]
FSB 133Mhz
CAS 4-4-4-12

no errors....

On a lot of PCs the RAM frequency is set to DDR3-1333 by default. To get something different, you may need to set the BIOS to use the XMP (extreme media profile) settings, or manually set the RAM frequency and timings.

Hi guys after installing some new RAM i checked CPU-Z to see if all was ok, and it doesn't seem to be.

I bought some Crucial Ballistix 8Gb 1866MHz, however is doesn't seem to be running at 1866 more like 667MHZ.

Is there way i can force the speed on the RAM to 1866?

Any input is greatly appreciated.


A:Memory Speed Issue

CPU-Z reports the clock frequency of the RAM. DDR (DDR2, DDR3) transfer data twice per clock tick, so CPU-Z reports 667MHz for DDR3-1333.

Most motherboards seem to run DDR3-1333 and up at DDR3-1333 by default. To get the higher frequency, you'd either need to set the BIOS to use XMP, or manually set the RAM frequency and timings.

A:Chipset and Memory speed capabilities

A lot of the newer Intel based boards can support either DDR2, DDR3, or both - but only one type at a time.

If your HP documentation only lists DDR2 as being supported then HP has decided to implement the board with only DDR2 capability and its a wise move. DDR3 is expensive and offers little to no gain at the present time in real world environments.

will it also work with the 266 and 333mhz ram and just downclock to 266 and also the motherboard is suposed to automatically downclock to 400mhz and match the cpu right?
so if it works the system will run at 400mhz fsb, and the memory will run at 266....right?? will this work??

A:cpu memory and motherboard speed issues

The BIOS in most motherboards is set to automatically detect the processor and memory and set their speeds. One issue you will have though is that the 333 memory will run at 266 unless you overclock the 266 RAM to 333. Most RAM will do that. You cant run RAM sticks at different speeds.

more than likely you will have to up your ram voltage to 1.65v in order to get it at 1600.....most are the same way, 1.5v will do fine for 1333 but most of the older ram not being marketed for SandyBridge cpu will need the 1.65V to see 1600, give that a try with the 9-9-9-24 timings and see how it goes

What is the fastest speed memory this board will handle? 2133/2400?i know it has 2133 in it now but will it run 2400?I owned a toshiba and it said 4GB was max, but I put 8GB in it and windows recognized it and it ran what about thisHP Pavilion 15-au018wm  what is the max ram really? 32GB/ 64GB? the "official line is 16GB, i know. but what will work?

quot Memory Speed defines the minimum access time that your RAM can physically handle and is rated in MHz Higher speeds indicate that the RAM can be made to run to faster The actual speed of the memory will be determined by the bus speed of your system and will step down if your system only supports a slower speed quot Bus Testing Speed Memory Bigger for This is a quote from a website selling memory I think I get the concept but is there a mathematical equation for finding out how much memory Testing Bus Speed for Bigger Memory you can add My system info shows what I currently have for memory My maximum capacity is Thanks SIW mb gigs right My maximum memory module size is mb one gig right Here s how I understand this The max cap is just that how much my computer can hold and the module size is what each memory stick can be Now taking into account the bus speed how do I know if the memory will be fully functional or if it will step down Testing Bus Speed for Bigger Memory for the bus speed Thanks for your time nbsp

A:Testing Bus Speed for Bigger Memory

4096mb is indeed 4gb and 1024mb is 1gb, so you're spot on

go to and run their scanner, it will tell you the speed of your current installed ram and what your mobo can take

if this isn't what you want to know then let me know

My motherboard has the following specs:

Processor: Socket 478 for IntelŪ PentiumŪ4 processors
Chipset: SiS 661FX + SiS 963L
Front Side Bus: 800 MHz / 533 MHz / 400 MHz
Memory: Single DDR266/333/DDR400x2

This means that it only supports "single channel" memory configurations? Can someone please explain this to me and how it creates a "bottleneck" issue with the FSB ?

I currently have 2 x 512MB PC2100 memory.

I want to upgrade to 2 x 512MB PC3200 memory. But I cannot have them work in dual channel correct?

My CPU is a P4 3.0ghz w/ HT 800mhz FSB, so basically thats 4 *200mhz. This works with PC3200 memory because that is 2* 200mhz correct? What multiplier/frequency settings would work for an overclock. Nothing big just maybe a 10-20% increase.

But can someone also explain what DUAL CHANNEL is - and i guess my mobo doesn't support it?


A:memory speed vs CPU FSB and overclocking questions

Having your memory in dual channel configuration gives you a greatly noticeable boost. This is because the CPU and GPU can access your memory, escpecially in large quantities, more easily; giving a noticeable increase in responsiveness and higher fps per RAM stick in gaming.

I'm sorry I can't aid you in finding whether your motherboard supports dual channel. Perhaps your motherboard manufacturing site (or Computer Manufacturer if the mobo is OEM) will have the motherboard manual which will almost certainly tell you if your computer supports dual channel.

I Just Bought Another Stick Of Kingston 512ddr 400 Ram And Installed. System Sees New Memory And Everest Software Says That Im Running @ 200mhz. Best I Can Tell With 2 Sticks Of 512 I Should Be @ 400 Mhz.
I Was Running @ 200 Before Adding Kingston Also. Anyone Have Any Words Of Wisdom?

A:K8v Se Deluxe, Adding Ram But Not Sure About Memory Speed

You can only run as fast as the slowest RAM chip or as fast as your mobo can handle, either your other RAM is slower then you think or your mobo doesn't support anything higher. Idk to much about AMD but that's how it works w/ intel.

I have a 256mb ram @400mhz(elixer), and I have another 256mb ram @266mhz (kingston)
Should i install the second ram chip along with my first?
In other words:
Which is better? 256mb @ 400mhz or 512 @ 266mhz
And what is the risk of overclocking the 266mhz ram up to 400mhz? Would it be reccomended? (my cpu runs @ 30-40 deg. if that means anything)
I use my computer to play light games, dvds, word and excel.

So, i first had a difficult time trying to figure out the details on my own, even after the college courses managed to royally confuse me on the simplicity of DDR.

After reading through this nearly 2 year old thread (SEEN HERE) figuring the operating speeds was a simple reverse engineering of calculation used to get the rated speed...

Ok, so now i know something is off.
After a quick (not really quick) 3DMark test, the results post saying my RAM is running at 889Mhz (SEEN HERE)

But my RAM is DDR3-2133 which should be 1066Mhz...

Uh, right...

So how do i manage to configure it to function properly? The BIOS says it is 2133, but windows is only using 889Mhz or the available 1066Mhz...

I am fairly certain it is a windows related issue.

I have a Inspiron e1505 with a Intel Duo Processor T2400 (2M Cache, 1.83 GHz, 667 MHz FSB). My current memory is 2 x 512mb DDR2 533 (PC2 4200).

I plan to upgrade my memory to 2 x 1gb. I was going to get DDR2 667 (PC2 5300) to match with the 667 MHz FSB. I do have the option of getting DDR2 800, but I think this would be pointless since the FSB is only 667.

Is this the right way of going about it? I'm no expert, but just from searching around the web this is the basic idea I gathered.

Thanks for the help

A:Memory upgrade, matching w/ FSB speed?

I think this would be pointless since the FSB is only 667.Click to expand...

IMO DDR2 800 is fine if its only a couple dollars more expensive.

Hi, I have just bought, with the advice of a store technical person (ha, ha) a 512mb pc2700 memory, the speed I wanted was pc2100. This I was told would work yet only at the slower speeed of the existing 128 pc2100 memory already fitted in the pc. I have since been told by a friend that this may not work correctly as they are not the same size (512 & 128) and that I should get two that match. Can anyone shed some light please, I am running windows XP home ed & processor 1.7 celeron. Many Thanks Bigsey

I have amd 3200+ cpu on motherboard abit nf7-s2 with dual channel support
and 2 identical memory sticks each 512MB DDR400.

When I ran the latest sisoft sandra, it reports:
memory bus speed 2x200MHz (400MHz data rate)Click to expand...

But I have DDR400...
Does it mean that each memory stick should work at 400MHz and NOT at 200 as reported by sisoft sandra?

A:dual channel memory speed

DDR stands for "double data rate". So an easy way to look at it is that it does things twice every clock cycle. That's why it's 2 x 200 or 400MHz.

It is running at 1300MHz constantly and it is suppose to run at 1600MHz, any reason why? Specs at bottom.

I find myself now having do upgrades on my computer since my husband passed away several months ago.

Due to video editing, that I now are involved with, I feel I need to upgrade the memory in my system.

The system is a hp 7680 and has 4 slots. 2 slots each have 1gig 533 mhz ddr2 chips.

My question is, if I add 2 more single gigs sticks, do they have to be 533 mhz or can I go to a higher speed chip, like 633 or 800?

hi all,

i have a computer running windows xp sp1. it has p4 1.7 cpu and 1g ddr sdram memory.
recently i noticed that the computer was very slow in opening up programs or some other simple operations. i have norton anti virus running all the time, so it should not be virus. i also scanned the system using adaware and everything seemed ok.

so i am just wondering if it could be the memory, as i am using two memory with different speed, one 512 at 2100, and the other at 2700. could that be the reason? any help is appreciated.

I Low speed Solved: memory postings just replaced my DDR memory with a dual channel pack of Patriot PC - x gb ram Its marked for MHz but my pc bios has it set for My motherboard is an MSI NF -G and says it supports up to MHz DDR ram I am assuming that the MHz listing patriot has the ram at is the max they overclocked it to Now I m trying to figure out how to get it there I m new to overclocking so if that is indeed what needs to be done any suggestions would be appreciated I ve already stepped up the FSB by and I have a benchmark test being run But my goal is to hit the mhz its rated for and the max increase that the motherboard has built in is which would only get me to MHz Any suggestions or thoughts would be great My build is the above ram and motherboard AMD phenom II x processor two Nvidia geforce GTS graphics cards Solved: Low memory speed postings in SLI Let me know if you need any other info thanks in advance nbsp

Hi there If I have a data bus size of 4 and and address bus size of 8 how do I determine the amount of memory that can be addressed?

If I wanted a processor to transfer 7 bits per cycle how would I determine the data and address bus sizes?

I forget the equations
