I7920 stock ghz + true = 62-64 under prime 95

pay attention to core temps. I don't know about your cooler (plus the brand is useless without the model number) but you are performing better than stock, from what I have read (I don't own a core i7).

Those sound a bit high with a TRUE (Enzo: that's a ThermalRight Ultra Extreme). What fan are you using?

What is your ambient (room) temperature?

Not hot at all. Not even warm, probably around 20 degrees.

Thats the cooler.

Now I managed to clock it to 3.8 and core temps remained around the 70-80s with the cpu at 58 if I remember correctly.

Then it was saying I only had 4gb of ram....

So I took it all back to stock to make sure the ram was fine, so now its back to normal ( 6gb 2.6 )

Then I ended up choosing that preset on the rampage which takes it to 3.2 I think.

Given up tbh. Running fine as 3.2. Think I will do some more reading before attempting to overclock again.

I think I had 1.25v at 3.8 and that was fine. Just said I had 4gb ram. It was stable though with prime 95 etc.

TBH I have been building, installing etc that computer for the past 8 hours now so I think I will just relax  

Hehe, you can always reseat your heatsink and reapply thermal paste, if you haven't tried.

+1

most likely a badly seated cooler, or badly applied TIM. clean both surfaces with isopropyl alcohol, and reapply. dont just blob it, use a bag or razor method.
