1.3V@4.9G Dual Superpi32M,CPU temp 50 degrees celsius
http://coolaler.kj.idv.tw/651c1/1.gif
when 9 loop , the temp. is reaching at 50-51 degrees celsius
http://coolaler.kj.idv.tw/651c1/2.gif
1.37v @ 5G running dual SP2004 with Large setting 9 , the temp. of 651 is only at 64 degrees celsius :banana:

1.40v@5.1ghz next
when IDLE CPU temp 39 degrees
http://coolaler.kj.idv.tw/651c1/4.gif
but when 5.2g,Vcore must 1.47v@Superpi32M
CPU temp 61 degrees

It's limit@air cooling maybe :woot:
5.3G@Superpi1M
http://coolaler.kj.idv.tw/651c1/10.gif
return to 5.1Ghz
dual Superpi32M pass@1.42v
http://coolaler.kj.idv.tw/651c1/11.gif
3DMark05 and then
http://coolaler.kj.idv.tw/651c1/12.gif
1.42v Could Superpi32M pass
but Vcore must adjustment up to 1.45v@3DMark06 CPU test passed

Awesome work, fantastic CPU! Intel's looking nice, even the Netburst! lol, 5.1 Ghz on air is fantastic :toast:
I take it you have plans to get her cold? ;)
That's amazing! Did prime fail during 5ghz?
I've been hanging out for these "C" stepping Cedar mills for a while now... now how long till' for sale in Australia ?
change ram to Corsair D9 512X2,16*319mhz=5.1G@32M 21m50.328s
