cdawall, I had done the same thing with the factory cooler on my PHenom II, took the factory gay fan, and put a high flow 120mm on top :laugh: hey it cooled pretty good.

Last night (it was around 1-4 am) I got my system cooler than on the first time. I put a "demolished" cardboard box on top of my rig to control the air flow and avoid the warm air circulation. This time I tried to go as high as 1.7 Vcore but didnt get that 3.9 :D I was tired too...

@Full, as high as 1.5 Vcore and over, the blacbox showed nothing, it doesn't show anything below 0... So... Don't know about BS, I put a thermometer to measure the incoming air temp, the lowest was -13,3C. After I quit benching, I checked the outside thermometer and the outside temp was lower than -20. The cheap wireless weather station doesn't show anything under -20 :rolleyes:

my board dont go that high mate! but hell ya that's sweet man, and its still running :shadedshu

GBT can't change the CPU VID, so in theory the board could do some over crazy volts.



So 9950 has normal Vcore 1.25V +0.60V = 1.85V
AOD shows 1.25V, setting it to 1.45V = +0.20V = 2.05V
And if AOD registry tweak can be done, then maximum in AOD is 1.50V
2.05V +0.05V = 2.10V

With PhII 940 which has 1.30V... it would be 2.15V

I don't now if its possible but it sure looks like it.

tried 3.5 but that takes too much voltage, forces me to go up in the 1.53v region and up and that's too much volts fa me on air.

go for it i won the max clock last time but you had higher volts this chip doesn't seem to care so i'm game :D



stock copper cooler like the one that comes with the X4 940. mine however has a 120mm 130CFM zip tied to it.

is the x4 940 cooler basically the same? i have a few 120 mms lying around along with cable ties

yep it is

when I had my board on a custom bench table I had going, I also placed a 120mm where the factory slow fan would go. Temps were pretty good!
