Hi all,
This is the first overclock I am trying in my life...
Been playing with the PC since last Friday, and although I got somewhere, I am not quite there yet.
The problem I am having is memory related basically.
First of all... the equipment is the following:
- i7 920 D0
- Gigabyte EX58-UD5 - F12 BIOS
- 6GB Corsair Dominator 1600MHz 8-8-8-24
- ATI Sapphire 5870 (stock settings)
- Prolimatech Megahalems CPU Cooler
What I want to achieve...
BCLK 191
CPU Clock Ratio 21x (~ 4 GHz)
RAM close to 1600 at 8-8-8-24
The problem...
Right now I am running the memory multiplier at 6.0, so 1146MHz and I managed to get it stable (18 hours prime95 blend and 10 counts of maximum stress on IntelBurnTest) with these settings:

Ch-A Address VRef. 0.750v [Auto]
Ch-B Address VRef. 0.750v [Auto]
Ch-C Address VRef. 0.750v [Auto]
The problem is that I want the RAM to run at 8.0 so 1528MHz...
What do I need to tweak in order to get it stable... I tried various settings but only managed to get random freezes (before or shortly after getting to desktop) and random restarts.
Any help is appreciated as I am basically against a wall as this is my first overclocking and don't know what to try anymore :(
Thanks
