DDR2 Memory Question

Q: DDR2 Memory Question

I have a couple of DDR2-4200 modules that i would like to put in my dad's computer. The only problem is that his motherboard supports DDR2-3200 memory. i was just wondering if faster DDR2 memory is backwards compatible with the lower seed DDR2 stuff.

It seems logical to me that the motherboard would accept it and run my memory(DDR2-4200) at the lower DDR2-3200 speeds. Could someone verify this or correct me if i am wrong(wouldn't be the first time).

Thanks in advance

Hello.

I have a MSI K9A2 CF V2.

It supports Up DDR2 1066 and up to 8GB.

I have 2 2GB sticks right now which I will be moving to another computer. I wish to buy 2 sets of 2 2GB 10666. The board support 4 sticks of ram. If I buy 2 separate of the same memory will I have an issue meaning 4 total sticks of the same ram. Meaning will the sticks do there little duel channel thing??

Thanks,
Kyle

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.
 

A:Question on DDR2 Memory

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.

my motherboard is an asus m2ne-sli motherboard. It says ddr2 up to 800mhz. Would it run DDR2 1000 memory at its full speed?
Or would i be able to overclock the ddr2 800 to 1000?
 

A:1000mhz ddr2 memory question

You'd have to overclock to get the full 1000Mhz speed from the memory, and unless you overclock the CPU with the memory there is little gain in running faster memory.

A friend of mine is upgrading his computer. He has an XFX 680i lt sli motherboard. What is better in RAM: 2gb at 800mhz or 4gb at 667mhz? He has XP. Also, should he get ECC ram, buffered ram, or normal ram? He wants to play games such as WoW, DIablo II, and maybe Crysis.
 

A:Ram question: ddr2 4gb at 667mhz or ddr2 2gb at 800mhz?

Four. You definitely notice a 100% difference in amount over 25% in memory speed - which isn't really noticeable anyway.

That mainboard uses normal DDR2 memory.

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.

I have a 1GB stick of pc4200 (533mhz) ram in my comp at the moment, which is an AMD dual core w/ a 2000mhz MT FSB, in an AMD M2N4-SLI motherboard. Im wondering whether it would be better to start off by buying pc6400 (800mhz) RAM or sticking with what i have, the question is would 4 sticks of RAM running at 533mhz which adds up to 2132mhz total (533mhz x 4sticks) be the same as 4x sticks of pc6400 since the FSB would handle them running the same speed (3200mhz total, much greater than the fastest the FSB can run which is 2000) is having the more powerful ram better if i have so much that the FSB cant handle the speed? Im not really knowledgable in this field so i thought id ask the pros.

heres a link to the motherboard:http://usa.asus.com/products.aspx?l1=3&l2=101&l3=323&model=1266&modelmenu=1

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?
 

A:ddr2 memory

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?

A:DDR2 Memory

There's a couple of things working against us (my system also uses DDR2 RAM).

1. DDR2 is obsolete, and has been for a while. As stocks diminish the vendors are going to charge more it.

2. Even though the recent fire in the Hynix factory probably didn't affect availability of DDR2, it was a good excuse to raise prices across the board.

High density memory is basically factory seconds that will
only function on certain motherboards at full capacity.
Always better to stick with low density.
Branded memory,like kingston,corsair,OCZ,crucial and so on
are usually low density.

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.

Hello,
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...?

Thanks..!
 

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.

Just what it shows in CPU-Z v.1.53 > CPU FSB = 1333MHz and memory runs in 333MHz Thanks in advance

A:Can I get DDR2 memory match

PC2-5300 memory is 667mhz when you factor in double data rate. As far as adding slower memory your speed will automatically be reduced to the slowest memory speed provided other things like timings and voltages are capatible. Mixing memory is always similar to a roulette wheel when things are mismatched.

The ideal solution when going to add more memory on any system is the same make, type, and speed even from the same manufacturer's batch to avoid ending up with problems from mixing. You wouldn't performance memory with standard dimms being two different types. In some cases a minor difference in timings can see an adjustment in the dram timings setting in the bios.

These are all factors to consider.

yes

667 is the fastest that it is rated to run at, it will run at all speeds lower than that including 533

unless you're planning to overclock, then there's no reason to spend the extra money on thr faster RAM because it will still run at 533

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).

Can you just take a computer that is running DDR2 memory and change the memory to DDR3 or do you have to add other items?
 

A:Substituting DDR2 Memory for DDR3

Memory controller and DIMM slots have to be DDR3 compatible.

So no, you cannot.

With an AM3 CPU you would need a new motherboard.
With any other socket CPU you would need a new motherboard, and possibly a new CPU.

Currently, DDR2 is better for most systems anyway.

We have a GeForce 8400 video card with 512 MB DDR2 ram. Our PC's ram is DDR type.
I'm wondering if the two types of ram are in conflict or if the card is possibly defective. When we plugged it into the PCIe slot, nothing would appear on the monitor. I shut it down and restarted the PC with the cable hooked to the onboard monitor port while the 8400 card was still connected. We got no picture there either. When I unplugged the 8400 and restarted with the onboard port, everything was fine.

Is this a conflict with the 2 different types of RAM, or are the two types seperate entities?

I read that to mean you can install up to 2GB in the DDR1 slots or up to 2 GB in the DDR2 slots but 2 slots will always be unused. Is this correct? The manual should make it clear but but to my mind it doesn't. Thanks for any clarification.

Yes . . that is correct . . while the board can use either types, it cannot use both.

Hi Guys,

Acer T180 with 2 X 512Gb PC2-4300 CL4 sticks. CPUZ reports as running at 100.5Mhz?

I want to add more memory.

Can I add 2 matched sticks of PC2-5400 CL4 1GB each
or 2 sticks of DDR2-5300 CL5 1GB each.
Both of the above at 675Mhz.

I have 4 slots each max of 1Gb; 2 used as above, 2 free.

What are the rules and implications for matching memory?
Is it correct that whatever I put in will run at the slowest speed i.e. the original PC2-4300 above?
Does it matter which slot pairs are used for which sticks e.g should the 1GB sticks go in the first two slots rather than the last.

I also see specifications like 5-5-5-15 , does that matter.

Wow, sorry for all the questions!

Thanks
Hew

Probably not, since the module is 4GB and the only ones listed as compatible go upto 2GB. That said, the QVL list only details the memory modules and sizes that have been tested with the board. It is by no means exhaustive, and other modules/sizes may or may not work.

I have an Asus P5W64-WS board. It runs the 975X chipset. I have upgraded to the latest BIOS and installed an Intel E6850.

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.

A:DDR2 Memory Issues Affecting System Reliability

Hi Kris2fer and welcome to W7 Forums

I've checked the QVL list, and those modules are listed. Did you buy these modules as a dual-channel kit of 2 modules, or did you buy them individually? The fact that both modules work when installed individually, but that they don't when used together in either single or dual channel mode would indicate a possible timing issue between the modules. You could try loosening the timings in the BIOS to see if that makes any difference (see pp42-43 of the motherboard manual).

Hello everyone i got a quick question for you memory pro's .

I am currently running ddr2 800mhz but my board can support higher ,would it be wise to upgrade to the higher speed ram ?

Or should i stick with planing to buy a new board and new memory all together, meaning a board that supports DDR3.

Im wondering if it would benefit me anything since im having alot of bsod issues now that have a higher stock chip and my ram is at the lowest mhz the board offers and my card always crashes playing left for dead 2.

I have not tryed other games yet but im figuring i need to get higher ram to support the cpu better can someone give me a good opinion my specs are already listed .

I am prepared to do either or but im thinking picking up 8 gigs of higher ram would be better like 1066mhz

Hello all. This is probably a very easy question to answer but I thought I'd ask just to make sure.

I am running Windows 7 (x86) on a desktop and have 2 gigs of Corsair DDR2 RAM (800mhz) installed. I also have a spare 2 gigs of cheaper DDR2 RAM running at only 667mhz. If I add the extra RAM am I right in thinking the faster RAM will run at 667mhz?

Is the performance boost of double RAM going to outweigh the loss in speed from 800mhz to 667mhz? Do you think it is worth adding the extra 2 gigs?

Many thanks.

A:DDR2 RAM 667mhz Vs 800mhz Question

You are correct that the memory will all run at the slowest speed of the bunch. You would barely notice a difference, outside of running benchmarks, with the slight drop in speed. If you can utilize the extra memory with the software you are running, then it is worth it.

However, there are two things to keep in mind. First, since you aren't running Windows 7 x64, you are likely only going to see about 3.25 GB in total. Second, anytime you mix and match memory, there is a chance they won't play nice together. The only way to know is to try them. As long as both sets are compatible with your board, you won't do any harm. If you start having random errors or lockups, then remove the slower sticks.

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: http://www.valueram.com/datasheets/KHX6400D2LLK2_2G.pdfClick to expand...

A:DDR1-DDR2 Video Card Question

Welcome.

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.
If you are in any doubt then post your system/motherboard maker and model/specification

A:can a 533MHz DDR2 RAM and 800 Mhz DDR2 RAM work together ?

If your motherboard is limited to 533 mhz then a 667mhz memory stick will be automatically underclocked to 533mhz, defeating the object of buying the faster ram. As for if 2 sticks of 512mb and 1gb work together side by side, I've never tried it but suspect it would work. If you get any problems, make sure you put the 1gb stick into the 1st memory slot (the slot your 512Mb stick is in at the moment) and put your old 512mb stick into the second slot. I remember reading that the CPU is happier running a bigger memory stick in the 1st slot. It may be an old wives talke, but its worth trying if you get problems.

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.

I have a computer I built and used since 2010 running well. It has two matched 4GB sticks of DDR3 for a total of 8GB. I have two remaining slots (empty) for ram on the motherboard to add more ram. Do I need to find the exact same memory as the ram I am currently using or does it matter?

A:Question regarding Dual Channel Memory- Mix or Match Memory

If you can get the same kit again it would be best but if you can get a kit with the same timings, speed, and voltage you should be okay. You should use cpu-z to find out your kit model and timings it supports. CPU-Z | Softwares | CPUID At the moment your two current sticks should in the white slots.

Hi, I have a EVGA e-GeForce 7600GT 256 MB PCIe Video Card which supports the SLI technology allowing me to link up 2 or more graphics cards for greater performance. Now this card has DDR3 memory. I wanted to know if I can link it up with a DDR2 memory graphics card which also supports SLI. If I can, how will this difference affect performance?

But if it's not another 7600 GT you're trying to SLi, just forget it, especially if you're going to buy the other card.

Hello people

i used to work with 2G memory and while working with graphic programs
i have always reached to 98% usage of memory

so few days ago i installed 4g more (2X1G kit & 2X4G kit)

Now whats strange here is

1. when windows up it started with 20% which is 1.2G i dont remember that with 2G i started with 60%

2. when i use many program together and push my memory to the limit then when i close them my memory doent get back to the low percentage that it had before run the prgrams

3. what should i do with the pagefile do i need it now ?
Thanks a lot
Friends

A:memory question

1) I would put 1.2 gb at startup as normal. It really depends on the no. and kind of apps and processes running. Offhand, I remember startup usage on 2 of my machines- one is about 1.25 gb, another around 1 gb.

2) Win7 is no stranger to memory leaks (apps not freeing memory when closed or memory usage just climbing on prolonged system usage).

Microsoft details Windows 7 memory leaks, hangs, freezes

A specific hotfix is described in that article, but generally speaking, keep windows and drivers updated- that may help. Other than that, rebooting the computer is the alternative.

3) Keep the pagefile at the windows managed size, esp. if you have large, memory hogging apps like Photoshop, WMC etc. running simultaneously.

So i have 32x Win7 I also have 8GB of memory.

My question is how much memory can this architecture actually see? its 32bit, so shouldn't it only see a max of 4? in the my computer properties, it tells me i have 8, but a bunch of programs tell me i have the 3.25.

Do i need to move to 64x? and what happens with the drivers for my custom built pc? will i be able to find them? (most of my disks wont install 32 bit drivers on win7 beta) i cant really do the vista driver backup with driver max, because i use XP

any help? ideas? suggestions? Thoughts? Comments? Wize cracks?

A:memory question ... 86x??

See? 8 but not 100% sure about this.
Use = depends on your system

Maximum amount of memory you can use in a 32-bit environment is 4GB but because several hardware parts have memory on them the amount of memory available to programs to work with is lower.
For example if you have a graphics card with 512MB of ram on it the max you can use drops to 3.5GB.

A few years ago, I added more RAM to my Gateway 650 Select desktop. With the Everest Home edition I can see now that I installed pc133 memory into my system which is set up for pc100. The thing seems to work fine with no problems. Should I take out the 133 and put in a 100 or is it okay to mix and match 100's and 133's?

A:Memory question

Is this for your Gateway, if so see here: http://support.gateway.com/s/PC/FX530_Series/1009172/1009172sp3.shtml

The board only supports up to 667Mhz for memory, if you install faster memory it will likely work but only at 667Mhz.

If you are not running a 64 bit version of Windows then you don't need more then 4GB, if you are then it may help to go higher but only for very certain circumstances.

I can find Kingston at other locations but the price is much higher than the $33 at Newegg.

Does brand name even matter? Or is memory just memory and they’re all the same?

It shouldn't be a problem. The faster memory will just run slower. As long as the memory supports your 133Mhz bus (533/4) it should work fine. If you already have PC2700, just get more of that.

Will taking the memory out of the computer when it is running fry the memory and the motherboard or just the memory?

Cause i well, did that and uh, i had to send the memory in for a replacement and they are sending my a new one, will that work or will i need to replace the motherboard as well.

By the way, when i took the memory out, my system was in bios, and i unplugged the system just after i saw the smoke.

there was black stuff on the memory and there might be on the memory slot, the slot looks okay, some of the pins might be placed wrong, but i have another slot that i can use if need be.

I will try and post some pictures this afternoon although i dont think it will be of much help because i only have a 4.2megapixel camera.

What does this mean:

Max. 3 GB unbuffered PC2100 / PC1600 non-ECC SDRAM Memory (PC3200 Max. to 2 banks only / PC2700 Max to 4 banks only)

I know I can use 3 sticks of PC2100 memory, but what about the others? Here is the mobo: ASUS Mobo

Importantly what that means to you is:
1. You have three "spots" to put memory sticks in.
2. You can put in those three spots up to a total of 3 GB of memory.
3. You should buy PC2100 SDRAM memory.

I have two systems, one where the motherboard just went. I would like to take the RAM from this system and put it in another system. The system with the bad motherboard has 32M RAM and the other system has 64M RAM. The system with 64M does have another slot for memory.

I have never increased RAM and I'm not really sure where to start or how to know if it is compatible. I also don't know how to tell if this system recognizes the extra RAM.

Any suggestions would be great!
 

A:Memory Question

If it is the same length as what is in the other machine you can give it a try. If it does not boot up then chances are it is not compatible. The computer checks the ram at startup. You should be able to see the count as it does that on the forst screen. If the count goes over 96000 before it continues to boot then you know it recognized it or you can download the program Belarc from the link below and run it. It will tell you how much memory there is.

http://www.belarc.com/free_download.html
when you put the memory watch the notch and make sure it goes in lined up with the spot in the slot.

Currently i have

Cas Latency 4
Timing 4-4-4-12
Voltage 2.2V
Well currently with my motherboard (GA-M55SLI-S4) i did my best to make into that settings but I dont think I did it correctly. Right now on CPU-Z it says my frequency is 2001MHz but jumps to 320MHz time to time, my CAS Latency is 4, and my timing it at 5-5-18-24(im guessing thats what things below cas latency means) i have also set my voltage to +.3(max). I heard that my default voltage was 1.8V so with .3 it would be 2.1v. My question how do I change the timing and is there a way to make voltage 2.2v?
 

A:memory question

There should be. First of all read your manual as to bios settings and how to change them. Now see if there are any bios updates that address memory voltage and or overclocking settings. If so install the newer bios. Next it is common with memory to default to slower settings. The faster timing usually only work with higher vdimm ie ram voltage. Once you set the correct vdimm, you can then set the faster timings.

I would test for errors with either memtest or prime95 [set to test ram] Having faster ram timing does no good if the system is not stable.

In this case, you are limited by how much RAM your motherboard supports. If it only supports 4GB, then you'll have to replace the motherboard with one that supports more than 4GB.

Hi

I wonder if you can add memory sticks that are not balanced. For example, one stick of 512, and one of 1gb. They are the same though, except different sizes.
I wonder if problems can occur because of that.

Also, would you guys help me find out how much total ram I can add to my system?
Because the guys from HP told me I can add to a total of 2 GB, and the guys from PQI told me 1GB. So I don't know which is it.

My specs are as following:
Motherboard Name: MSI MS-6577
Chip: North Bridge Intel Brookdale-G i845G

I have 2 slots. I was told I can add up to 1GB per slot. Recently I was told that I can only add up to 512 mb. So, I'm kind of confused.
