Q: Solved: DDR2 memory in DDR motherboard ?

Hi, I'm about to but a new motherboard and the specs say it takes dual-channel DDR3 memory. Will it be backwards-compatible? I'm hoping to use DDR2 mem as these RAM appear quite a bit cheaper at the moment. Thanks all,

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.)

I'm back with most of my parts for my new build.

I have the memory, but I didn't get the dual memory, they sent me just one, one gig memory card. Does this have to be dual memory where the two cards come together or can I order another one just like it and it work the same.

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.

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!

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:need new motherboard socket 775/DDR2

I use Newegg as a measure of what's currently available. (They only ship to the US and Canada, though.)

With your list of requirements, you get Hobson's choice (no choice at all): - ASRock G31M-GS R2.0 LGA 775 Intel G31 Micro ATX Intel Motherboard

You'd get more choices if you were willing to go to DDR3. (At Newegg, 2X2 GB of DDR3 1333 is available for less than $20US.)

I hope that an industry standard motherboard will fit in that HP. (I have no reason to believe that there will be a problem. I just have an abiding suspicion of appliance PCs.)

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.

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?

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

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.

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

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'm helping a friend upgrade his HP Pavillion a1030n computer. Right now it has two 256K stick installed in the No. 1 and 3 slots (from left to right). I was going to upgrade with two 512 sticks. Would adding those up the RAM to 1.5 Gigs or do all four have to match? And it adding the 512 will work, do I put those in the 2 and 4 slots or put the 512s side by side in the first two slots and the two 256s in the 3 and 4 slots? Or do I just add two more 256Ks to have a total of 1 GB?

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.

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.

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).

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: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.

I have a Dell 4700 Desktop with two sticks of 256MB (PC2-3200) DDR2 RAM. These are installed in the 1 and 2 DIMMs in order to take advantage of Dual channel memory.

However, I am planning of adding two more [different] sticks (1GB each) to DIMM slots 3 and 4. Will the system still take advantage of the dual channeling, in this setup?

Also, I am wondering greatly if I buy this new RAM, and it operates at PC2-4200, 5200, or 6400, will this disable the dual channel? What PC-xxxx RAM should I go for?

Also what is a good CAS latency to look for on RAM? What exactly does the PC2-xxxx number refer to?

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?

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 all! I recently bought an HP 15-e043cl laptop with an AMD A6 Richland processor. I want to know what frequency the memory controller runs at so I can install the fastest RAM compatible (is this right or do I have it backwards?)

I used Speccy and CPU-Z, and they both said my motherboard was a "Hewlett-Packard 1982". Google searches were futile as they'd only show either boat motors or old computers. I also checked the manufactures website, but it only provided me with the max amount of RAM (8 GB). The frequency of the RAM chip that came pre-installed is 800 MHz (PC3-12800).

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...

Also I think your 2nd link is the same as your first

A:Solved: Motherboard Not Detecting Full Memory Capacity

You have 64MB of RAM going towards onboard video. Onboard video shares the system RAM since there is no dedicated RAM available for the onboard video. On most BIOS's, you can set how much RAM gets shared with the video card. Hope this helps.

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.

Hi all,

I have Intel's D-915 processor, D102GCC2 Mob, 512 MB 533 Mhz DDR2 (UMAX)

I want to put another 1GB of DDR2 RAM in other slot. Can both work together well.

Also if I will go for 1Gb 667Mhz DDR2.. then ? Any problem..

Plz Suggest..


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.

I just purchased 4GB G.Skill DDR2 1066 MHZ RAM and installed it into my motherboard (Gigabyte GA-MA78GM-S2H). I have tried fixing the problem by readjusting the vdimm voltage to 2.1 volts after reading on the G.Skill website that 2.1v is compatible with most motherboards. After doing so, I tried to change the settings in my BIOS to manual so i could reconfigure the RAM to a 1066 mhz option but the max still only shows as 800. Please help me out if you know any way i can change the frequency to the 1066 mhz my ram is actually supposed to be .

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.

I'm looking to upgrade replace my current 2x2GB DDR2-667 modules with 2x2GB DDR2-1066 modules in a couple days but I'm wondering if I really need that!

I mainly write software and run linux on virtualbox on that particular machine and so far everything works really well but I'm looking forward to game a little on it as well, after a video card upgrade of course!

So, would I get like a reasonable performance increase with those ddr2-1066 modules or should I just forget about them and keep my current setup?

Does your motherboard support the DDR2-1066?

A:BSOD's Memory I think... Maybe Motherboard memory controller?

We do need the actual DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

It is almost impossible to spot trends from a single DMP file so if you have more than one please upload them. If you only have one please wait until the computer crashes again then upload both.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

I'm buying some corsair xms2 ddr 2 does anyone know which cl is better 4-4-4-12 or 5-5-5-18 and which one might over clock best? thanks for your time.

A:Solved: Ddr2 cl ?

The lower timings are "quicker" As for overclocking, it would be best to buy faster ram; ie if you are going to buy 800, then buy 1066. This will leave you a LOT of room for upping the fsb.
