Hello friends! i really need your help!

my system is:
MB: striker II formula 1.7.0.1 bios
CPU: q6600 @3.0 ghz --->cooler zalman cnps 9500a led
Ram: ddr2 ocz reaper hpc 1066mhz@1000 mhz 5-5-5-15 4GB (2+2)
HDD: St BARACUDA 320 gb 7200 rpm
GPU: BFG 260 MAXCORE OC2

when i run prime 95 i got this error:

FATAL ERROR: Resulting sum was -1.547425047703786e+026, expected: 1.590712368459496e+017
Hardware failure detected, consult stress.txt file
Torture Test ran 0 minutes- 1errors, 0 warnings.
Work thread stopped.


please tell me what could it be and if it can damage system? how i can solve it?

Your overclock is not stable...

Running like that will slowly corrupt data on the drive and blue screen.

You need to see if it's the cpu or the ram doing this. Run stock and re-test.

If OK at stock, start your OC slowly. You may need to change voltages. Read the OC stickies for info.

The stickies will really help you out.

Best "shot-in-the-dark" is that either your RAM voltages are too low or your RAM timings are too tight. Loosen them or raise the RAM voltages (Not above the manufacturer's recommendation) and re-test.

First step is definitely to read the OC Stickies.

I've checked the voltages and used memtest (3 passes) and everest ultimate (6+hours) to stress the system and it had no errors, or blue screens, the problem is only whith prime 95, maybe something wrong whith this program or it is not compatible with vista? x64? quad?

nothing new in this guide. tried so many combinations so i don't know what else can i do.
i can get stable only with maximum 3%cpu oc (2.48ghz)

here my voltages

cpu voltage: 1.13750
cpu pll 1.54
cpu vtt 1.30
memory 2.20
nb core 1.28
sb core 1.55
1.2 HT 1.2
Bridge core 1.2

CPU gtl_ref ---> auto
NB gtl red----> auto
ddr II controller ref----->auto
ddr II chanel a_ref---------->auto
ddr II chanel b_ref---------->auto

loadline calibration enabled

well thats an easy fix. Your cpu voltage is very low, start increasing that and you will be able to get a higher stable overclock (as stated in the OC sticky).

anything below 1.3750 will not even post if OCed @3.0ghz. as kyeana said i raised my voltage, set the cpu voltage to 1.5v. i succesfully passed the test for 1 hour which i couldn't pass before (prime 95 gave me an error after less than 5 minutes of stress). and max temps were 2-3 lower. i will check the system tonight for much longer time .
thank you!

below 1.1375?? the previous poster said to increase it to 1.35

wait.. CPU: q6600 @3.0 ghz <- what stepping is it? G0 or B3?
I'm running q6600 @ 3.6 at 1.45v.
I still think its the ram - Asus has issues with OCZ. Try updating the bios with the latest version.

I had this issue once where stress test failed @ 1.53v... I somehow accidentally changed the wrong settings and changed the cpu voltage to 1.4 and it passed.... lol... stroke of luck i guess.

Your mem timing might be too tight.
Auto.. not good... find the base line and enter the details manually
NB gtl red----> auto
ddr II controller ref----->auto
ddr II chanel a_ref---------->auto
ddr II chanel b_ref---------->auto

right now his ram is probably fine, just keep it at a 1:1 ratio and keep the timings loose until you get the cpu all worked out, then you can tighten those.

In terms of vcore it is looking much better now. :) keep increasing it as necessary to acheive a higher overclock, just make sure not to push it past 1.5 volts and make sure to keep those temps down.

Good luck

You're not by any chance running ASUS Probe during the stress testing are you? I'm in the middle of OCing my E8600 on my ASUS Rampage Formula, and I had all sorts of trouble stress testing on Prime using ASUS Probe to monitor my NB and voltages.

Now that I no longer use it while stress testing, it's been stable for 12+ hours on much lower voltages than I had initially. With the ASUS Probe, I couldn't get it stable for more than a couple of hours, even with higher voltages.

No idea if this is related to you, but I saw the Striker II Formula so I thought I'd throw it out there. Good luck with the OC!

whith 1.35v my temps are very high, something about 51 idle and up to 68 at load.

can someone tell me in two words what is cpu/nb/ddr2 GTL REF? what it does? i saw the article about this but because of my english i didn't understand much from it.

thank u

base line? how can i find it?
