Apparently, not an amazing one. It is cooler than my previous 920 by about 4-5 degrees at the same voltage (Or maybe the cooler is sitting better this time), but it doesn't clock much better apparently. The memory controller is far better though. The one on my 920 didn't like DDR3 speeds over 1500Mhz much, this one ran my RAM at 1866Mhz (9-9-9-22-2T, 1.635v) with no issues (This is with 6x2Gb, to boot).
I spent half the day I had spare overclocking it. I managed to POST at 4.7Ghz, but there's no way to get it anywhere near stable there on air cooling (Took over 1.4v to POST it). Highest stable I got was 4.17Ghz at around 1.33v on the cores. Highest memory clock was 1866Mhz. Fastest QPI was 3600Mhz (7.2G/T) or so.
At the end of the day I just decided to dial it down to a nice and cool 24/7 setting running 133x25 at 1.056v (The same clocks as the above pic) but with the memory running 1333Mhz at 6-6-6-15-1T timings. Passed 20 rounds of Linpack like that, so I'd call it stable (And fast enough for anything but a larger e-peen
). The best part at these settings is the load temp. I am loading to around 55c in LinPack, but under, say, prime64 it tends to keep below 50c under load (The ambient in the room is around 24c, and I have the Mugen 2 over AC MX-2 with a pair of Scythe S-Flex 1200RPM fans in a push-pull config on it).
Sorry for no more pics/screenies, I am gearing up for vacation (And have tons of things to finish up) so I don't have time for a full pretty report.
In other news, my oldie P4 died....*sniff*. It survived for so long, but it looks like the olde P4P800-E Deluxe just gave up and died. It was a good board, too. Did 280FSB (Around 4.2Ghz with my S478 Prescott was the setting it died at), pretty good for its day. No idea what I am going to do with the AGP HD3850, the EL OCZ DDR1 (Does 400Mhz at 2-2-2-5 timings at 2.85v) and the rest of the stuff.
Also, the stock 975 might have given it away as well...
to Thrackan for pointing me to a great UK site...
