Fully lapped Xeon x5675 CPU
I have lapped this cpu for around 2.5 hours to get it right, I got the ihs down to the minimum thickness to reduce temps, by exposing copper and lapping CPU to an almost complete flatness.
It ran at 4.49 ghz at around 46 Celcius in games on 10 cores besides of 2 cores that ran at 56 Celcius as many of you know it's the soldering on those chips. That is on basic Geminii S524 air cooler, on water or better cooler you will better deltas. Of course you can take this chip higher. Multiplier of 25 max + BLCK overclock (based on your motherboard). I ran mine on Asus P6x58D-E
Motherboard had a faulty ram slot, so I don't have a use for this chip currently. I took my time with lapping too, so I know someone will appreciate it here :-)
