Strange computer problem...

[jfrog]

My fairly new build listed in my sig is giving me problems:|

When I set the memory's command rate to 1T, if the system's cold, Prime95 will halt within a minute with FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

If I do a warm boot, Windows XP Pro will BSOD with DRIVER_IRQL_NOT_LESS_OR_EQUAL before it even finishes loading.

Now, If I set the memory to 2T command rate, everything runs fine and the system is stable.

However, I ram Memtest 86 with the memory set to 1T, no errors:Q

So, I tried my older video card(FX 5900), still crashes at 1T.

My memory(Corsair TwinX-1024 3200C2PT) is certified to run at 1T, but it ovbiously isn't a memory problem.

I'm at a loss here...

Anybody?

I need some guidance here, as my computer isn't running as it should be...

What does the stress.txt file say?

Read around , I heard that early users of the K8NS-Ultra had problems with 1T - possibly a newer bios revision would fix that problem

Corsair has a list of SPECIFIC recommended timing settings for their TwinX memory for each motherboard model they've tested. Go here: http://www.houseofhelp.com/v2/showthread.php?t=38150

Tried the newest BIOS AND the recommended settings from Corsair. I also read around, and set the HTT freq. to 4X.

It turns out I have CMX-512 modules, as reported by Aida 32 and on the sticks themselves. ZipZoomFly sent me the wrong sticks, but it's too late to return them now(my fault, should hav checked them). Anyways, my friend is gonna sell me his OCZ 512 sticks(2-3-2-6@2.7v) for a good price. I'm gonna move the Gigabyte motherboard to a watercooled setup and get a MSI K8N Neo2 Platinum. My friend has this MSI board, and it runs my Corsair fine at 2.5-3-3-6@1T, 2.7v. Also read that the MSI is a better board all around.

Thanks for the help. Much appreciated.
