Prime95 error

post #1 of 5
Thread Starter 
First, my specs:
Intel Quad 2.4Ghz Q6600 B3 stepping
EVGA geforce 8800 gts 512mb
Team Elite 4x1GB 800Mhz RAM
Antec Neopower 550w
Abit IP-35e Motherboard

Today I had problems playing some demanding games, such as DiRT and Team Fortress 2, which always crashes during cpu intense parts, (for example, on DiRT, I can access the main menu, but when I am about to race, it crashes). The thing is, my CPU is at its default settings, with no overclock. I ran prime95 in its blend test and I got an error immediately, "Fatal error rounding was 0.5, expected less than 0.4." I switched to the test which is less RAM intense and so far after 1 hour it didn't get any errors.
So my conclusion is that my RAM is defective? I ran Memtest and it didn't report and errors, but I heard cases like that before. Should I try bumping up the VDimm voltage? I currently bumped it up at 1.85V when it's recommended setting is 1.8V. Thanks for reading!

With the 4X1GB of RAM you may need to bump up your NB voltage.(MCH)

Bummer homie, but $10 and my left pearl say your RAM is busted up. I had some bad RAM, and a 14 hour memtest couldn't get it too fail, but 'real' life always did. I RMAd, and now I am

Try testing your stick individually, both in memtest and in real applications.

It is still possible you need to up voltages, but if it was fine for awhile and now it's not, sounds like you have a cavity...

Thanks for the replies! I built the computer with this RAM at about last November/December, and it usually only has problems when I overclock the CPU. It's probably worn out because of it tho. But upping the MCH voltage from 1.25 to 1.33 really helps! I also upped the VDimm to 1.9 volts and I have to say that Team Fortress 2 works flawlessly without crashing, although Dirt is still unplayable and crashes right after the loading screen.
