Guys, all of you don't tweak Engine/Memory clock much? Because in 14.6 Beta you just can't.
Same goes for fan speeds, sgminer doesn't control anything, so even I said holding them at 75% it went 100% on X*290 machine one time.

Pretty much what kozmos pointed out here: https://bitcointalk.org/index.php?topic=658975.0

Also the temps spark +10*C (up to 80*C; 14.6 beta vs 13.12/14.4) which I feel a bit of a struggle to manage under 40*C outside summer temperature.
As far as I remember I had several times when temps were going just around 70*C under same conditions with same external fans.
