Prime95 v.25.5 FATAL ERROR

Hi, I'm new to the this and I'm using the program to stress test my machine for ocing purposes

I downloaded Prime95 25.5 for 64 windows

I went into Test > Worker threads and changed the Priority from 1 to 10

then I ran a torture test and received this when choosing In-Place large FFTs and blend




[Wed Mar 05 15:13:23 2008]
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
FATAL ERROR: Rounding was 4, expected less than 0.4
Hardware failure detected, consult stress.txt file.



when I run small FFTs, it works


my specs are as the follows without overclocking

vista 64 bit ultimate
asus p5k deluxe wifi ap
e6700
4x2 Gskill pc2-8000 5-5-5-15


Can anyone explain that error to me? I'm running Prime95 off my desktop and I couldn't find this stress.txt file it directs me to

the only thing I can think of is that I'm running the RAM at 1066 through my BIOS?

any help would be greatly appreciated!

First of all, download the latest beta version of Prime95 (25.6).
Also please explain why do you want to change the priority from 1 to 10.
If 25.6 also fails on your PC, then download the latest official release (24.14) and put it into 2 different directories. In each directory set CPU affinity to different core. Run both executables choosing one of the following scenarios:

1. small FFT test on both of them
2. small FFT test on one and large FFT on another one
3. small FFT test on one and blend test on another one (if you encounter an error here it would most likely be related to RAM or chipset)
4. large FFT test on both of them (error may be related to RAM or chipset, or CPU cooling)

BTW: did you overclocked your PC? If yes, then reported errors simply mean that your machine is not "prime-stable" and you have to experiment with your settings (there is no easy answer then).
BTW2: what are your voltages (Vcore, Vram, etc.) in BIOS and under windows (especially under load) + what PSU do you have?
BTW3: what are your temperatures in idle and during stress?
