System instability caused by RAM

Hello,

I bought a new 1gb stick of RAM for the comp i was putting together. The RAM specs are

-PC3200 DDR
-Unbuffered, Non Ecc
-CAS Latency 3
-Chip density: 128x4

The mobo is a PCChips M861G.

So, when I got the PC put together and starting installing XP, things started going wrong. The installation would blue-screen at random points and/or the installer would say that it could not read from the CD. I could not finish installing.

I guessed that it was a memory issue, and changed one of the BIOS settings. I set the memory to 100Mhz instead of the regular 200Mhz.

After doing this, I managed to get through the installation. Windows is working now, but it is unstable. The programs I am using sometimes crash, and every so often I get a BSOD.

Memtest86 reveals that the memory is still having problems.

I have read that 128x4 chips are incompatible with certain motherboards. Could this be the problem? Or if the module was incombatile, would the computer not even boot? BIOS recognizes all 1gb, although I don't know if that means anything.

The reason I need to know is so I know whether or not to return the RAM. They only accept returns on defective modules, and incombatibilty is not considered a defect.

To sum up: how do I know whether the problem is a bad RAM module or whether it is incompatibility?

Thanks!

Where did you buy it? Most stores will take back memory if you say it's defective. If they ask "how do you know?" you say "it wouldn't pass MemTest86."

Most of the time they'll say "uh...ok" 'cause they won't know what you're talking about.

Make sure you say you bought replacement ram somewhere else so they'll give you a refund or at the very least store credit. You don't want to take the chance that it IS an incompatibility issue and receive the same ram as a replacement.

Is this fraud? No. You're not knowingly ripping off a company. As far as you know, with the tests you've run, you have bad ram. You have no way to prove whether it's an incompatibility issue or defective.

The problem is that the eBay seller states that he will not accept returns on defective modules unless I can confirm that it is indeed a defective module and not an incompatibility issue.

So how can I find out which it is--defective module or incompatible mobo?

LOL. Have I stumped everyone with my question?

a. You bought used RAM from someone on ebay - LOL
(you should have bought from newegg for an easy return avenue)
b. You gave no info on video used or RAM brand. LOL
This mobo comes with el crappo unichrome onboard graphics which shares with system RAM - LOL.
If you are using it - go and buy a ti4200 for $50 and turn off embedded video in bios.
c. Did you install latest 8-30-05 BIOS? LOL

d. Did you check to see if RAM needs more than 2.5V to be stable? LOL
e. Did you install nothing-but-grief VIA 4 in 1 drivers? LOL
Only use Win XP generic chipset drivers, and nvidia graphics for ti4200
f. Did you check to see if your CPU (unspecified) is compatible with mobo? LOL
