Now newbie overclocker...
I got this on an X58 UD3 mobo with a lot of other nice stuff all for $600 on ebay a couple of weeks ago.
After buying a Noctua D14, last night I managed to get it up to 3816Mhz - 18 x 212. (18 is max).
Temps under testing are around 70 max.
The only other things I touched were uncore (12) and memory (x8).
Couple of software crashes this morning. My theory is memory, so I might loosen the timings. does this sound right?
I use this machine for Archicad renders which use all cores, so very pleased that now it clocks 867 on the cinebench R15. To do that with stock new bits would cost a LOT more.
One thing I don't know is why whenever I up the cpu voltage (or play in any way with any voltages) I get bsod.
I've tried a lot of things mentioned in this and other forums but no good.
So I read on....
Meanwhile I'm happy in the knowledge that my cheap chip can play with the big boys.
Also happy that quite big renders take minutes instead of hours so more money
