Core i7 975 XE Breaks 5 GHz Barrier, With Air Cooling (http://www.techpowerup.com/92543/Core_i7_975_XE_Breaks_5_GHz_Barrier_With_Air_Cooli ng.html)
Intel's newest high-end processor, the Core i7 975 Extreme Edition is gearing up for launch later this year, on course of which, it already passed a milestone. Xtreme Systems Forums member PcCI2iminal scored one with overclocking a Core i7 975 XE D0 stepping chip past the 5 GHz mark, 5015 MHz to be precise using only air cooling for the processor, with an ambient temperature of 20 °C as claimed by the overclocker. Its cooling was care of a Thermalright Ultra Extreme 120. Its partners in crime were Biostar TPower X58 motherboard, and Corsair Dominator DDR3-1866 memory. At that speed, the setup made it through a CPU-Z validation (http://valid.canardpc.com/show_oc.php?id=553302). PcCI2iminal was further able to put the chip through SuperPi 1M at a speed of 4750 MHz, where its crunch time was measured 8.672 seconds.

This is stupid insane, right? I would like to know his ambient temps as well as CPU temps.

20c ambient apparently

I will beleive it when the retail chips hit the shelfs. To many times these early chips received by certain OCer's perform far better than any retail chip.

Oh damn! I wish I had known that a pic of your POST screen and your rig was good enough proof...I would have taken a few pics of a certain e8600 running just past 5ghz with 23c ambient.
