Standard DRAM Memory

[jellybelly20708]

Recently upgraded from 4 GB of CM2X1024-6400C4 800MHz 4-4-4-12 in my Abit IN9 32X-Max motherboard. I had been running Vista 32 HP. I first replaced the memory with 8 GB of CM2X2048-6400C4DHX and brought up Vista which ran apparently with no problems for a short while. I then took the system down and then did a clean install of Windows 7 64 bit Ultimate. All went well until I started getting Blue Screens intermittently. I eventually ran memory diagnostics which told me I had a memory hardware problem. I then removed one module and rebooted with 6GB. Memory diagnostics ran fine. I then reinstalled the 4th module thinking maybe I got lucky and found the bad module or possibly it was seated incorrectly. Failed diagnostics. I then put the suspected bad module in slot 3 and ran with 6 GB again. Again diagnostics passed. So the memory modules seem to work at least as atotal of 6GB. I do not overclock or have not changed any clocking or voltages, etc. from defaults.

So I have concluded that I either have a bad slot on the mobo, a mobo problem or possibly a video card conflict (GeForce 7900GS).

Any thoughts or suggestions?

Thanks, Jim

To rule out the memory, or alternatively to verify which one of them it is that's causing the problem, test them one at a time in slot 1 on the motherboard. If they all pass, then install one of them in slot 2, and run the test again. Then move that module to slot 3, and so on until you have tested all four modules and all four slots.

If you have a bad module, we will replace it per the terms of our warranty. You can either contact our Customer Support department or use the links on our RMA page to request an exchange.

Thank you for your suggestion, however, I did that and none of the memory modules were bad. That is to say, any module in slot 4 would cause the BSOD. Since I had been running the systems for a couple of years with 4-1GB memory modules, I believe that the problem is not with the slot.

I have received suggestions to tweak the voltage a little which I will try soon.

Thanks, but a bad Crucial memory module is not the problem!
