OCCT 1hr stable, Prime95 fails/crashes in minutes?

post #1 of 9
Thread Starter 
First off. Here is my CPU-Z validation so you can see my specs I'm running. http://valid.canardpc.com/show_oc.php?id=1670546

I can run OCCT 1 hr full stable with max CPU temps below 45º @ 4GHz. Error free. Within a few minutes of Prime95 Blend running 9 times out of 10 I get "Prime95 has stopped working" and closes down. The other 1 out of 10 times, i get Worker #5 error. It always seems to be worker #5, and none others.

When OCCT/Prime runs, the cpu volts jumps to 1.500V due to LLC. My NB frequency is set to 2869mhz, and my Cpu/NB frequency is set to 1.30 or 1.325 if I recall correctly. My DRAM volts is set to 1.55V on my Gskill Ripjaws DDR3, running underclocked at 765mhz..

My computer runs fine 100% of the time, in long intense games and everything. I am wondering if I should really worry about being Prime95 stable if OCCT runs for 1 hour and everything works as it should?

Are you using Blend in prime ? It's probably your cpu/nb or ram.

I don't understand why underclocked RAM would need extra volts? I'll boot into my BIOS and see what my cpu/nb volts is set at, i cant remember

Sometimes needs, even if underclocked. My old G.Skill 2000 6-9-6-24 @ 1.65V, needed 1.7625V for 1870 6-9-6-24

I had issues with Prime95 in blend... it would fail.. sometimes quick, sometimes after multiple hours... but it would only fail in Blend. Never had an issue with small FFTs... But Blend would screw with me

i hate searching. i just read a couple nights ago, if a worker fails, its nb voltage or ram voltage. its memory related from what i read. could go back to cpu voltage too. i dunno. definitely voltage somewhere from what i gather.


@IOSEFINI like my 1066mhz 5-5-5-15-23 geil will not run at that speed even with 2.2 spec volts. it will however run at 800mhz 4-4-4-13-18 at 2.19*volts.

If you can pass small fft, but fail blend that means one of these:

1) Too high NB frequency
2) Not enough CPU-NB voltage
3) Unstable memory (too tight timings or not enough volt)
