lol I hate when that happens. Still, 16 loops says its likely a banker, so all good.

Like you im running a single loop - 2 x gtx260, mb and cpu on a PA360 and a PA240 (10x1800rpm yates). I maxed out heat wise at 4.675ghz 1.52v. 4.7 would continually fail on about loop 17 or 18 when core0 hit 96c. Dumped the gfx cards out my loop and went mad on fans for a weekend and made it to 4811.6, but with low uncore and memory speed. Your temps look bang on for a well setup single loop, I reckon youve got the heat capacity for a bit more . Looks like your cpu isnt quite as good as mine but I'm putting my money on about 4.65 totally maxed out. Id be happy with that for a 920!! My best "only" did 4420mhz (c0 stepping - best d0 out of 5 only did 4.38ghz ). Had to get a 950 to get over 4.5ghz, but lucked out and got a golden one.
