Problem with Overclock EVGA 680i Sli A1 + QX6700- HELP GUYS

Hi guys, it's been a while since I was here.

I am currently trying to overclock my brother's system and of course encountering all sorts of trouble.

My brother's system:

Case: NZXT Tempest
PSU: Ultra X3 1000w
MB: EVGA 680i SLI 122-CK-NF68-RX
Bios: P33
CPU: QX6700 Quad Core 2.66Ghz
CPU Cooler: Thermalright Inferno IFX-14 with 2x1900rpm Scythe slip stream fans SFF21G
RAM: Corsair XMS2 4x1024 DHX C5 PC-6400 DDR2
HD: Samsung Spinpoint 500GB HD502IJ
GPU: PNY 8800GTX
Optical: Samsung DVD RW

From what I have come across on the net, this is a very troublesome Mobo for overclocking purposes.

Nevertheless we will not accept defeat until death knocks on the door!

I have tried a number of different setting on the BIOS. Initially just changed the multiplier from 10x to 11x and was running no problem at 2.93 Ghz with all the voltages set to auto.

The trouble began when I tried 12x multiplier. It just wouldn't even load from the BIOS but that's probably because the voltage settings were on Auto.

We then read a lot of different threads looking for some ideas from people with similar rigs.

Of course all previous attempts prior to this wouldn't load at all or just freeze completely in the Microsoft Corporation bit whilst loading.

Came across some settings from the net and used it as a base to try and get somewhere with the System.

Currently the settings below are what I'm using in the Motherboard:

When I try and load with the above settings there is a short 1 minute freeze in the Microsoft Corporation bit and goes to the Log on screen.

After logging on it loads all the start up programs and I even start Everest to check temperatures (45 degrees Celsius on CPU Idle, etc.) and then it freezes completely requiring a reset on the case to reboot.

I assume the above is because the settings aren't correct yet to get closer to stable.

I would greatly appreciate any help trying to move further from where I currently am.


Many Many Thanks Guys!
