Yeah its boost clocks. It's an XFX R9 290 DD. Yeah it can go that high Bisjac, just look at my furmark score. It ran that stable with no artifacts whatsoever, with 5 back-to-back benchmarks to test temperature cap. It works 100% on benchmarks, but when I run Grid 2, it barley goes above 600MHzz. I get 20-30 FPS on Grid 2, but get this- no matter what graphics settings I use. BF3 runs at 10 FPS with no GPU activity listed at all. Counter Strike GO actually works fine at the highest settings (70 fps), but it still hovers around 600-700 MHz, it just isn't a massively demanding game.
The CCC's little "activity graph" will stay at 0%, then jump to 70% or maybe even 100%, but it will never stay up there and actually run the loving game with good frames. Can't believe I paid $1200 for a machine that can run a game that my laptop could and a benchmark.
Before you tell me to use driver wiper and redo the drivers, let me tell you the hell I've been living.
The "stable" driver from AMD for my card will crash the system every 2-3 minutes, even in idle, with a kernal power error. I reinstalled Windows 7, and did drivers, no dice. I installed Windows 8.1 and had all the drivers ready to go on a flash drive. I used the "beta" driver from AMD and that will actually work and let me play SOME games.
