Can I get DDR2 memory match

Q: Can I get DDR2 memory match

Need help. On my Gigabyte EP43-UD3L mobo ; Q8200 2,33GHz I have 2x1G OCZ PC2 9600 [1200MHz] memory. My question is can I add two more 2Gb sticks let's say PC2 6400 [800MHz] or PC2 5300 [333 MHz]
Just what it shows in CPU-Z v.1.53 > CPU FSB = 1333MHz and memory runs in 333MHz Thanks in advance

Preferred Solution: Can I get DDR2 memory match

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 http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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.

I find myself not really understanding what the best optimal memory config is for this little rig based on the available parts I have laying around this is an older Dell Dimension Intel G chipset Pentium GHz Dual channel memory four slots total mhz FSB I have x GB PC - U- - mix/match Dual-channel DDR2 in banks? Best -ZZ x PC - U- - -C and or x Best mix/match DDR2 in Dual-channel banks? PC Best mix/match DDR2 in Dual-channel banks? - U- - -C to mix match The first question I have is how do I know which bank is bank ' ' and does it matter the banks are color-differentiated physically thankfully Second which config will deliver the best performance A - Dual channel GB each in first slot of each channel or does it matter which slot as long as its dual channel Total GB B - Dual Channel GB each in one slot of each bank pls one each PC - U- - -C mb in the 'other' slot of each channel bank total gb C - GB each in one slot of each bank plus one each PC - U- - -C in the other slot of each bank total gb

A:Best mix/match DDR2 in Dual-channel banks?

I'd stay with the 2GB of DDR2-800 (PC2-6400) only. All of the RAM will run at the frequency of the slowest RAM. It's not worth the performance hit to only add 512MB.

That assumes that the PC actually runs DDR2-800 at its nominal frequency.

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 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.

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.

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?

Go here, click scan my system, it will show what RAM you have in there, as well as what RAM (of Crucial's products) will work in it.
You can also go to Corsair's site or www.kingston.com and manually insert your PC model number to find out which of their products work in your PC (to do some price comparison)

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.

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.

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.

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.

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?

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).

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.

FSB Speeds on CPU and Memory don't match-is that a problem?

I had a guy help me build a computer last fall and I was looking to upgrade the memory when I noticed that the speed on the CPU and the Memory don't match. Here is what I have....

ECS KT600-A mobo
AMD Athlon XP 2400+ Thoroughbred 266MHz FSB Socket A
Kingston ValueRAM 512MB 184-Pin DDR SDRAM DDR 333 (PC 2700)

The Mobo will support a CPU with speeds of FSB 400/333/266 MHz
and memory of DDR400/333/266 DDR SDRAM

My questions are

A. Will my computer run faster if the CPU matched the Memory?

B. Given the choice should I get an extra stick of 512MB ram at DD333 OR upgrade the CPU to match the current Memory?

C. (least likely (read no $) option) Scrap both the RAM and CPU and shell out for a new CPU and Memory that run at 400MHz?
Thanks for any advice you can offer.

A:Solved: Memory match

No, not every stick will work (not for sure anyway). I guess though, Kingston is your best bet. You should match the timings and of course the speed. Usually matching the timings will do the job (3-3-3, 3-3-5 etc, you should find those numbers on the sticker of your RAM or printed on the module itself. Just get RAM with the same timings).

As for the speed, RAM runs at 200Mhz which equals to 400Mhz DDR. It has nothing to do with the 64bit CPU, it's just the way DDR RAM works.

Hope I helped!

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

Just had a new P4 motherboard installed: ECS P4M800PRO-M478 (V1.0) which replaced the original Celeron board that died suddenly. The new motherboard has 4 memory slots, 2 for DDR1 and 2 for DDR2. This board has a maximum 2GB capacity. The manual says you can't mix memory types. 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.

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).

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.

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: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.

Its best to match the speed at which you know your motherboard will operate.

DDR2-533
DDR2-666
DDR2-800
DDR2-1066
Which motherboard (computer model number would suffice) do you have?

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?

Now this card has DDR3 memoryClick to expand...

Which card?? "A card with DDR3 memory", or "A thingy with a red switch on it" tell us just as much.
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.

Q: Ddr2

I have 2x2 Gb DDR2 memory, but I would like to have a total of 8Gb, is it possible?

A:Ddr2

Hello Stefi,

Yes, it sure is. Looking at your Asus P5QLD PRO motherboard specs at the link below, you could just add another set of 2x2 GB DDR2 RAM modules of the same MHz timing to have a total of 8 GB.

If you are not sure of what your RAM timings are, then the free program Speccy can help show what they are.

I have 2 gigs pc3200 ddr 400 on my mobo and I'm looking to up grade my ATI 9550 256mb AGP card, which has DDR mem.

My question is will an AGP card with DDR2 memory be compatable with the DDR on my mobo?

If not what AGP card would be a better upgrade?

No problem. Memory on a video card does not have to match your MB memory.

I have a 6GB mix of OCZ Reaper 8500 DDR2 and 9200 DDR2 running at 857mhz, 4-3-3-5-2T in my system and it's great. I also happen to have a 2x 2GB kit of G.skill around here.

I am contemplating swapping the 2gb of 9200 in my system for the 4gb of G.skill giving me 8GB instead of 6GB. I'm mainly just curious if I can make it work more than anything, but curious if there is any real point of 8GB vs 6GB of DDR2.

Thoughts?

A:8GB vs 6GB DDR2

If its just an experiment go for it and have fun, but unless you really need the extra 2gb, I doubt that you're going to see increase in performance...

A:Which DDR2 Ram

I think its much of a muchness but heres the qualified vendors list from Asus P5Q-PRO-QVL.pdf

anything not on that list may give issues and need manual setting for timings and voltages but may also give no problem if you carefully match them to the motherboard

If i get a 2GB DDR2 will it perform any adavantage? I am currently using 4GB DDR2. Will the 2GB be over taken by my 4GB? Im wondering this because one of my games doesnt look as good as i want it plus i want to enhance performance.

EDIT: I have a dv4 1275mx will the DDR2 fit?

A:If i get DDR2...

looking good and performance are two different animals, more so when it comes to laptops.

More memory might be able to yield more FPSs (Frames per Second... speed!) if by that much, better visual of graphics comes from your Video card & CPU and I am thinking that having an Onboard chip as a card, does not do well when playing games.

Now, if you give us a little more feedback of what kind of games and what you use the laptop for, we can perhaps help better?

A:DDR2 Ram

You need the RAM that is compatable with your motherboard.
The CPU and Windows version give no hint to that.

As Windows MCE was OEM, its likely to be a brand name (HP, Dell etc), so if you could supply the actual maker and exact model, we could probably help more here?

I have an ECS P4M800PRO-M(V2.0), Pentium D 915 OC to 3.2GHz, 2GB PC2-5300, and I am running Windows XP Pro. My board supports up to 2gb of PC2-4200(533MHz) and that is what I ordered on Ebay but I received 2GB PC2-5300 instead. I'm not complaining except my board only reads 1GB PC2-4200. I know the speed is backwards compatible, but I do not understand why the BIOS only reads 1GB. DX Diagnostic Tool, PC Wizard 2008, and CPUID all read 2x1GB PC2-5300, but the BIOS does not. Can anyone explain this to me.

A:DDR2 Ram

RAM will only work at the FSB of the motherboard, or at the speed of any slower RAM fitted. Fitting faster RAM will not make it run faster than the FSB of the motherboard.

Wish to upgrade my memory in my desktop by a further 2 Gb. Currently have 6 Gb of DDR2 800mhz memory in a Advent Centurion cq9204. problem is dunno how many pins the memory sticks have, it aint written anywhere on them.
Any thoughts.
 

A:Ddr2 ram

you currently have 6gb of ram, what are you doing that you require another 2GB? for majority of people 4GB is enough. So unless your doing some heavy photoshop graphics your probably wasting money on more ram, you may want to use that money toward something else to see more of a performance increase.

I just bought a Gateway tower at a garage sale with no hard drive or no memory. I inserted another hard drive from an older gateway machine but I have no idea what kind of Ram I need to get. It has a Pentium 4 CPU. The serial/model number on the box reads : 0025768844/MFATXSTL ELP 500C.

From what I've hard it needs DDR or DDR2 ram but which kind will work on this machine?
 

A:Do I need DDR or DDR2 Ram?

From the gateway site it uses pc2700 ddr memory.
BTW if you input the serial number into the gateway site, you can see everything you want to know about that system.

All,

What does the following mean:

Registered/Unbuffered
Voltage
Cas Latency
ECC/Non-ECC

and what areas will make it more faster (example will Cas Latency 4 be faster then Cas Lantency 3; ECC vs Non-ECC)? Is higher the voltage better?

Thanks!
 

A:Ddr2 Ram

You'll want to match RAM voltage to your MOBO, 184pin 1.7v for example.
Lower Cas letency is faster, you can find 2, 2.5 and 3 usually, but the lower the latency the less stable the RAM is. Usually if you find a 3 it is Buffered and/or ECC for stablity.
ECC is error correcting code, it detects when your RAM has errors, which is nice, and can even fix single bit errors. Usually ECC is used in servers and isn't of HUGE importance in most home PCs, registered RAM is recommended if you plan on breaking the gigbyte barrier with ram though.
