I had been able to overclock the cpu to 2.7ghz, or 1200FSB with default voltages on everything besides the Memory voltage which was manually set to 2.1v (I have 8gb on 2x Corsair TWIN2X4096-6400C4DHX) as i have all the banks full. I achieved rock solid stability but it thought it was a measly overclock (everybody i've talked to has got this proc minimum to 3ghz).

The problem now is that at those settings mentioned above anything past 1200FSB means that the computer will not post.

So what i did was set System clock to "Manual", DRAM clock to "800" and CPU
voltage to "+0.0250" , changed NB voltage to "1.35", SB voltage to "1.6" as i have 3 hard disks and 3 optical drives, DRAM Ref. V. at "0.975" and all limiting features disabled (C1E, EIST, Spread spectrum, D.O.t.).

Now the computer always posts but as soon as it show the desktop and all the application/processes are loaded it freezes, shows a black screen or resets after a BSOD.

Any tips?

This are my specs:

MSI P7N Diamond bios v.12
Intel q6600 B3 with Coolermaster Hyper TX2 cooler
8gb on 2x Corsair TWIN2X4096-6400C4DHX
2x 8800gtx (BFG and Sparkle)
3 x HDD (WD raptor 74gb, WD raptor 150gb and WD Caviar SE 160gb)
1x Plextor Premium CD-R\RW 52x/32x/52x
1x Plextor DVD-R\RW PX-760SA
Lian-Li PC1200B plus
Thermaltake Toughpower 1500W Modular PSU
Windows Xp x64 sp2

Cheers!!

If you read through the thread alot of people were using a Q6600, there is alot of good info here. You should find a good starting point. Keep in mind auto does not mean stock. Once you start overclocking stuff like your pll and vtt gets almost dangerously high on most boards. I never tested this with a multimeter. You might need to replace the TIM on your chipset with something like MX-2 since you have all of the dimms occupied. The northbridge runs hot and that seems to have helped alot of people out.

You may have hit a FSB hole they are random and huge on these nForce boards. My e8400 hit one around a 440fsb. It sounds like you got a good board though. With some tweeking and research you should see good results. Good luck.
