4Gbs of Memory Installed Only 2Gbs Showing

[sohilurs]

Hello guys today i bought a 2GB DDR2 Ram for my GA-G31M-S2L Motherboard. I already had a 2gb ddr2 ram installed on the motherboard. I went to MSY and bought this new ram and installed it. I turned the computer on and was expecting to see 4GB of ram but all i see is 2.75GB!! I have no idea what the problem is becuase i have 2 DDR2 Slots and they are both installed with 2gb rams.


Can someone please help me?


Thank you ALOT!

I also used RAM Memory Upgrade: Dell, Mac, Apple, HP, Compaq. USB drives, SSD at Crucial.com and found out the maximum ram capacity is 4gb. A possible resolution to this could be that windows xp cant support more than 2.75gb of ram...

If you want to see the full 4GB, you would need a fresh install of XP 64 bit. It sounds like you have the 32 bit version installed.
If you are going to try that, then I would suggest you at least try out Windows 7 first. My G31M motherboards run that well, it might be a better option for you than the XP one.
That was using a Pentium D at 3.2GHz and a Pentium E5500.
You might still see some of the ram "missing" due to the built in graphics chip using some.

Any 32 bit operating system only supports a max of 4gbs of total system memory. This not only means the RAM, but the graphics card memory and memory within a few other components. So depending on the graphics card you have that could account for the drop.

As Paul said the second possibility is that your on-board graphics is now using more system memory, you might want to check the boards bios to see what the settings are set to.

Have you double checked that both of your sticks are actually 2gbs? It could be possible that they accidental sent you a single 1GB stick. Try removing the old stick and verifying that the new one is actually showing as a 2gb stick.

PS - note that I changed your thread title, please help or I need help isn't very descriptive and often leads to members not wanting to bother clicking on the thread. When posting to forums a descriptive title helps us know what you are looking for and might even help others with a similar problem.

IIRC that board does not seem to run with mismatched ram sizes, although the ones I had tried were a 1 gig and a 512 meg, but it is still worth checking. Speccy from piriform.com or CPU-z from cpuid.com should help you dig deeper without needing to pull the memory out.
