Hi all,

Spent the last 2 weeks now messing about trying to overclock my 920 D0. I have an Asus Rampage 2 Extreme motherboard, Corsair Dominator 1600 6GB (3x2). The cpu is water cooled with a heatkiller and I have a 4870x2 also in the loop.

It's really getting me down now because all I seem to be doing each night is testing, testing and more testing.

I managed to get 4ghz stable in Linx and Prime 95 using:

Vcore - 1.275
Vtt - 1.275
Vdimm - 1.65

All other voltages are set to manual, lowest.

I have LLC enabled for this clock. When I check the idle voltage load in cpu-z it says 1.264 and under load it stays the same in cpu-z but in everest is goes upto 1.32-33 (load).

I thought LLC kept the voltages more or less the same, regardless of load, when it was enabled?

Is CPU-Z correct as in the voltage stays the same under load too or should I take what everest is saying as true?

I then read it's better for the cpu and motherboard to disable LLC as it gives a much cleaner power and voltages will drop on load.

I tried to get 4.2 stable with LLC off, I set the vcore to 1.375 and in cpuz it showed 1.36 and under load it went down to 1.256 which is a massive drop and the inevitable bsod occured. I then set vcore to 1.4 and again it dropped massively under load.

I'd really appreciate it if someone could explain LLC to me in simple terms and whether its better on or off?

Why is my load voltage dropping so much also, do I have a potential fault?

Really hope someone can help me, just about come to the end with it.

Many thanks,

RoEy
