Morning all, I am fairly new to the OC process, but I have been reading tons and tons and I think I am at a point where I am just not sure where to go next. I can not get OCCT or Prime to run longer than 5 seconds give or take. I can run 3d Vantage and Mark with out issues and it has been stable all day like this.
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!
