My set up is:
Ram- 4GB (2X2GB) Patriot EPP 6400LL Series 800MHZ O/C to 926 on 5-5-5-15 2T @ 2.20V
CPU- Q6600 2400 O/C to 3340 idle 34 degress according to core temp (Stepping B3 Rev G0) Can't run a load to see what the loaded temps are
Mobo- Asrock 4CoreTwins P35 Bios 1.40
Water Cooled with Swiftech 220 Kit

Bios settings-
RAM- 5-5-5-15 @ 2.20V CPUID shows the 926Mhz with 4:5 FSB:DRAM
CPU- 371 CPU Freq 1.50 CPUV CPUID shows 3340 -371 Bus 1484FSB @ 1.488V
NB/SB/VTT all set to Auto.

I have played with voltages for a while now.
I had to losen my RAM from 4-4-4-12. (Ran MemTest for 2 hours straight with out errors) To get it to boot properly.

but no matter what it wont run a stable test past 2900. I can boot fine, and I can use the PC fine, just not sure why none of the tests support the over clock. I can drop core volts to 1.48 and I get the same results.. any ideas? I would like to think I should be able to run at 3.3 or even higher given my temps.

Any advice / replies are appreciated.

Thanks!

The test of stability remains some sort of stress testing. Since you have 2 different stress testing programs bothing indicating a failure I suspect it is a real stability problem and not a SW glitch. 371MHz isn't that high a FSB for the P35 chipset. My ASUS P35 board will do over 500MHz.

Maybe as an experiment try determining what the FSB limit on your board is. Lower the multi to 6X and then start raising the FSB until you see stability issues in OCCT or Prime. For example if you lower the multi to 6X and try a FSB of 400 you would be at the default clock of the CPU (2400MHz). If it won't run stable there then it indicates a limitation of your motherboard. Keep going until you know your FSB limit of the board. Then at least you know its limits. You may have to play with voltage settings as you go. Since the FSB is highly dependent on the NorthBridge P35 you may need to bump it's voltage for FSB > 400MHz.

The P35 runs fairly cool (compared to the Nvidia chips anyways) but keep an eye on it when bumping its voltage. A simple finger touch test can suffice. On metal, if you can keep your finger on it, then it less than 60C (rule of thumb... or should I say finger).
