I got a R9 290x TRI-X 4gig SC( 1040 / 1300 ) and i have this problem with my gpu clock that drops while gaming and i know its not a
temperature issue because on full load i run beteween 65 and 71 celcius. my PSU is a EVGA supernova 1000watts . My cpu is a I7 4770k
oc at 4400mhz and i got a MSI board GD65 . My OS is WIN 8.1 X64 on a mSATA and game on a mecanical hd seagate 7200rpm.
I dont know if it throttling but my drop are not regular and it can go to a drop of 50mhz as well as 400mhz .
What can i do ?? Any suggestion.......
I think it's supposed to be doing that as that is powerplay at work.
Dynamically changing the clocks based on the load.
You can download RadeonPro to force full 3d clocks on the games you have it with.
I'm not crazy, my mother had me tested! Dutch Overclockers Unite
