I can run this q9550 on AIR to, This q9550 is such a good overclocker, that my Voltage for running 4Ghz completely stable is only 13mv higher the the VID of the chip itself, Time to brag.

I got to 4.630Ghz at only 1.44volts which a Your TRUE or my H50 can handle.
at 4.5Ghz i achived that at only 1.408volts
at 4.3Ghz i ran 3dmark06 at 1.312volts
at 4.0Ghz im 24/7 stable with only 1.232 volts and my temps stay below 50c and on cold days, i see one of my cores drop to 19c idle T_T.

*step 1*I booted my computer at stock voltage and stock 2.833Ghz and ran Super PI and got 16 seconds. The voltage 1.184volts.
*step 2*Reboot the computer
*step 3*Then I just changed my FSB to 471 and didnt touch my voltages exept on the memory, and the memory clocks and timings.
*step 4* I booted up at 1.184 volts stock voltage but at 4Ghz
*step 5* I ran Super PI and it ran just fine and from 16.8 seconds i went down to 11.5-11.8 seconds at stock voltage Lols!!!.

Im contemplating on running my q9550 at 4.2Ghz 24/7 and let my loads hit 65-70c. I probably will when i get my SLI bridge up.

I might go for 4.7Ghz suicide later on but i want to keep this golden q9550 for a long time because its with the big hitters.

*NOTE* We should make a overclocking club on mod, but i dont think alot of people here overclock there hardware.
