Recently, I have encountered several computer problems. The first of all of my problems started before I installed the new RAM, when Windows XP got the BSOD before startup. Trying to fix the problem, I decided to attempt to repair. Unfortunately, I have several Window XP disks and each one was somehow corrupted. Then, I wanted to do a fresh install. Trying to get to the fresh install was a pain however, as I was put into an endless "Setup is continuing" every bootup.



Anyways, this is besides the point. I finally got Windows XP to install, and once I did this, I installed DDR2-Dual Corsair 800 5-5-18T RAM cards. So, the computer was running very smoothly, and in the middle of playing "Platform Racer 2" the computer crashed. Ok, no big deal, this happens with a custom built computer every now and then. Ok, so I go back to the computer and browse the net - CRASH! I decided it may be the RAM, and I tried switching the slots. However, when this happened, I recently realized I did something incorrectly and only 2GB are active. The time of the computer running is about 5X longer, and I have yet to see a crash.

Which leads me to the main point - Is there a reason that only 2GB works with the computer, and not 4? It may just be rotten luck, but I am unsure.

Specs:
ASUS P5ND2-SLI Motherboard - 4 Slots, 8GB Supported
Intel Pentium 4 CPU 3.2GHz
OS = Windows XP Pro. SP2 32Bit
NVidia GeForce 7800 GTX

Any advice would be greatly appreciated. I would love to fix the problem myself, but It was unfortunately my brother who built the computer (which honostly, he built terribly) and he doesn't know what the problem is

Try to check the frequency of RAM which is newly install . Is it match with your mother board?
The BSOD error mainly came with the problem of RAM.

could be a bad memory module, have you tried running memtest86?

Alright guys, thanks for the answers, but it turns out i made a blatant mistake.

The motherboard I have can only support 533 and 667 MHZ. I have RAM with 800MHZ

Anyways, as you can see I'm obviously not an expert at this. Does anyone know if it's possible to change the amount of MHZ to 667 or 533?

You can't adjust mem speed for mismatched mem types.

I would take a look in the BIOS and try a couple of different bus speeds with that RAM...nothing to lose but a few minutes of time.

Louis, very late I am aware, however, after a little tweaking in the BIOS I managed to find an option to change the frequency as well as latencies.

I am now running at the recommended 4-4-4-12 at 667MHz. Thank you very much for your assistance.

While Louis mentioned this. Faster memory can be run slower but slower memory running faster is overclocking and can cause problems.


Edit: PS. Thanks for responding with your results!
