So I recently picked up a 290 unlocked to 290x from another forum member, and I've been having throttling issues, even when the temp is quite low.
In doing some testing, I've noticed that with WoW open, the core speed throttles alot. With the graphics turned down, the core went as low as 600mhz. After turning up the graphics and going to a more demanding zone, the core went up to 800, but still fluctuates down as low as 600. I've tried setting the 50% power setting in both CCC and AB. The clock speeds appear the same in CCC AB and GPU-Z.
The core temperature is very low (60C), and not approaching anywhere near the cap of 95C. The fan speed is set to 70%, but again, the fan isn't kicking in because the temp. is quite low.
I've noticed that in GPU-Z, there's a "render test". This 3d image causes the card to max the clock out at 1000mhz, even if wow is also open.
I've tried raising the maximum power limit, but this doesn't seem to have any influence over the throttling.
Does anyone have any idea what could be causing this?
I've done a bit of reading, and I can't find anything that would force a constant clock speed in 3d. In my EVGA overclocking tool there was something called "K-Boost" which would force maximum clocks 100% of the time.
Surely there is some way to make sure this card runs at 100% clock speed...
BTW I'm using 14.4 CCC
