Running prime 95 on my Q6600 and I keep getting an error on core 2.

[Mon Feb 01 17:54:26 2010]
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

Any ideas what might be causing that error and where stress.txt may be found (as far as I can tell there's no placement option?

Running 425 x 8 = 3.4ghz core voltage is showing as 1.288 in CPUZ but set to 1.3250 in BIOS.

RAM set to 2.2v as per manufactures setting. OCZ reaper at 850mhz (1:1). Had it running fine at 900 on previous OC (12:10).

I'd probably say you need a bit more voltage.
Have you adjusted the fsb term & pll voltages?

No they are both set to auto, I wasn't sure what voltages to put them on as I didn't want to kill anything.

I have:

FSB Term "AUTO" (1.2-1.5)
PLL Voltage "AUTO" (1.5-1.8)
NB "AUTO" (1.25-1.7)
SB "AUTO" (1.05-1.2)
Clock "OCV" (0.7-1) - What is this?
LLC "AUTO"
CPU SS "DISABLED"
PCIE SS "AUTO"

Any ideas on safe(as can be) settings?

Any idea what they're set to at the moment?
I usually add +.1 or +.2 to most voltages.
You might also need some more NB voltage

I dunno, what can I find out with? BIOS just states auto.

I'd say look in the manual for the default values and set them manually? Then you can start notching it up.

You're more likely to kill something on 'auto' voltage if my system is anything to go buy. The auto setting seems to massively overvolt the CPU. I reign it in by doing it manually.
