After couple of hours and sometimes even the next day computer locks up while on desktop,doing nothing or sometimes while playing the game.

First I've tried with higher VCore but it's all the same from 1.375 to 1.45. Then I moved on to adjust the other voltages and tried different voltage combinations for SPP, MCP, FSB and HT, and noticed that they are best if left at AUTO(which is completly different from my previous Core2Duo E4300 that needed these voltages set manually for decent overclock). If I set these voltages at anything else then AUTO computer restarts or fails Prime in matter of minutes. Memory is out of question because it's completly stable(tested with Memtest 86+).Also, tried x8 multi with 450 FSB and it wouldn't even boot.

Does anybody have any suggestions on how to resolve this? All help is very much appreciated.
I'm not sure if you actually have a G0 or not, since you copy and pasted your message in two threads, and it looked like you were spamming. Sooo, I'll assume you don't. Even though that thread says G0 people can easily wander into the wrong place...

3.6 might be tricky if you are using a B3...
For 3.6, which I wasn't very comfortable with, it needed 1.5475 vcore, and 1.55v for the MCP <-> SPP, and 1.5v FSB. It was stable in the tasks I did, except for long duration heavy load.

My B3 did 3.3 easily. Here were my settings (with vdrop mod).
Vcore: 1.45v
VFSB: Auto/1.4v (1.5v set manually in here works great too)
Memory: 2.1v
SPP: Auto
MCP: Auto
MCP-SPP: 1.45v

The vdrop mod is very important on the 680i board. Since it drops pretty badly. These worked VERY well for 3.3. It did a full 24/7 Prime Small FFT, and ran WCG just fine as well.

I also have a G0 that I got yesterday, it's an L727A. It's doing 3.6 @ 1.45...still doing small FFT's right now. Going on 7 hours. Will do a full 24 though!

The only difference now is that I can do 3.6 with my vFSB @ 1.5v. And it's looking good!

And two hours prime is NOTHING. Make sure you do small FFT's at least..

You also need to keep in mind, NOT every chip is a freaking winner. And don't be lame and return it because it didn't clock the way you wanted it to. Testing to find your max clocks is better, and then once you do, lower it a bit until it's stable 24/7.

you need to read through this thread for volt settings...i can boot at 450 x 8, but i see no dif in running 400 x 9
QFT. One guy in this thread also left some voltages on Auto, and that works just fine also. I believe he left his MCP-SPP auto, as well as the actual volts for MCP/SPP. You absolutely don't need to shove so many volts at it to get it to run STABLE. As long as you do the VDrop mod, you are a-okay! That's what matters most when you overclock the quad.
