I've been using SP2004 (Stress Prime 2004) in Blend mode to verify the stability of my overclocks. It is but one of the tools I use but I like it because it is one of the most rigorous tests for determining whether an overclock is stable or not.
Here's my scenario. If I run SP2004 standalone it will run absolutely stable, well over 24 hours. But if I run something else while SP2004 is running then it fails. For example, I had SP2004 running absolutely stable for over 5 hours. Then I went on the Internet via Firefox and also open up Nero to burn some DVDs. It was shortly after this when SP2004 failed. Here's the SP2004 log file:
"FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 5 hours, 38 minutes 33 seconds - 1 errors, 0 warnings.
Execution halted."
This only happens when I run other apps. The test does not fail when I just let it run, even over 24 hours.
So my question is, do I need to run SP2004 standalone for proper results?
The overclock:
Venice 3000 core @ 2700 MHz, hovering between 1.61-1.63v.
G.Skill memory @ 270 MHz (540 DDR), 2.62v; DRAM Freq = 180; 3-4-4-8
LDT = 1.3v
PWM IC = 50C
