Hey guys, any chance that someone could take a look at these settings and see if you can recommend any changes?

Currently trying to get Q6600 G0 stable at 3.4. Running on a P5KC motherboard with 4x1GB of OCZ 800MHZ 2.1v 4-4-4-15.

Prime 95 will fail on worker #2 after a minute or so on small FFT's.

CPU Ratio Setting 9
FSB Strap to NB 400mhz
FSB Freq 377
PCIE Freq 100
DRAM Freq DD2-754mhz
DRAM Command Rate - Auto
Dram Timing info (Relaxed) 5-5-5-17
CPU Voltage 1.45
PLL 1.5
FSB Termination voltage Auto
Dram Voltage 2.1v
NB Voltage 1.55
CPU & PCIE speed spectrum - disabled
C1E Disabled
TM Disabled.

Any help would be greatly appreciated

What is your CPU VID?

Are you running a stock cooler?

VID is 1.2375. I'm using an artic cooler freezer pro 7. Current temps after playing FSX for 4 hours at 3.4ghz are 66-69. Still cant get through a small fft test or a blend test though.

VID is pretty low. I think that you are being limited by your cooler. By today's standards, the ACF7P is at best, an average cooler.

Here are three under

$50 heatsinks that are pretty popular:
COOLER MASTER Hyper 212 Plus
Xigmatec Dark Knight

They all require a somewhat different approach to applying thermal compound.
