2 PC's .. 1 with 2 280x's and 1 with 2 290x's ..all running 1 WU each for now and latest vulkan beta drivers on both. no cpu crunching at all


when i look at my tasks the 280x is getting WU's of 120,000gflop and finishing in 10mins or so.. 290x is getting 20,000gflop WU's and finishing in 6-8mins. if i look in the individual tasks it shows peak speed 10,500gflops on 280x and 3,500gflops on my 290x's ....something is wrong here is it not?? i dont really understand this stuff..just doesn't look right to me

Looks normal to me.
Dont worry about those GFlops values.

Your 290x MB times look very similar to my 390x times. Also the only tuning parameters I'm using are: -hp -cpu_lock

Your 390 has 80 MHZ higher core speed.
Of course its faster in particular.

both 290x are also overclocked to 1150/1400
both 280x's are overclocked to 1130/1600

both 290x are also overclocked to 1150/1400
both 280x's are overclocked to 1130/1600

My 390x is running at its factory clock. 1080MHz / 1500MHz
My i5-4760K is overclocked from 3.4GHz to 4.0GHz

I'm running 0 tasks on CPU & 1 task per GPU. Also I'm using Cat 15.7.1.

I did test overclocking my 390x to 1134MHz / 1575MHz (5%) but I didn't see any gain in doing so compared to the increase in power.
