Edit: @ donmarkoni

i owe you one, got stable @ 1.270v first with 1.84 CPU PLL, think 1.3-1.4 was bit too low, and now i tried CPU PLL 1.7 and yeah atm 10passes stable which looks promising, most of the time i pass the first 5 LinX runs the other 20 runs stable too . Idle temps are pretty low now 36-38-34-32

Great! Very low vCore, almost default.

donmarkoni - can you post up ur BIOS settings please? Really interested in ur settings. Just cant get over 220 blck stable. Thank u very much in advance.

No problem, just to check them out once more and I'll edit this post.

Don, how high can you get with QPI Slow Mode disabled? I noticed in your screenie that it was enabled.

225MHz, maybe a couple of MHz higher, but didn't tried. 230 is a no go, whatever I do. Tried max 1.4V IOH. I don't know if I should go higher just with air cooling.
BTW, check this post again in couple of minutes if you want to see BIOS settings I used.
