getting 4gighz with xq6700

[silveralx]

well i might be asking for to much. I bench 18500 on 3dmark 06 with 8800 gts in sli but i still can not get my chip to hold 4 gighz
qx6700 intel
nf68 evga board
evga 8800 gts
ocz 4 4 4 12 at 800mgz
can any one help?

why do i get artifacts is the board temp a possible problem?
well i leave the video cards at a speed i tested at before i try clocking up the chip.
i only get it when i push the chip past 3.9 gighz

well for power supply's i have the pcpower 550w and the thermaltake pci-e sli power of 250w
here are my scores http://service.futuremark.com/compare?3dm06=1467548

3D artifacts are due to the VGA cards themselves, your motherboard dosn't cause these. Your VGA core/mem clocks must be too high, or you have a bad card.

What cooling is this?

QX6700 at 4GHz produces a tank load of heat, if it's throttling then it's no use trying to make it work for the long run.

What are your CPU temps? What Vcore?

I would probably aim for around 3.6GHz with the QX6700, but this needs ace cooling.
