R9 280

[OfficialS_Face]

I have a twin frozr R9 280X 3GB Card. I've seen various benchmarks hitting anything between 500 - 650 h/s but I can't seem to get mine above 307. Claymore says it should be getting 400 ,h/s which is still low. Am I missing something ?

P.S This is in a dual GPU rig alongside a 380x which running perfectly fine.

Video in Russian, but all the useful information is in the picture.
I myself do not use 280x for a long time.
Zcash (ZEC) on it can be more profitable

I don't have a R9280 but I've a couple of R9270x cards, one a 2GB and one a 4GB and I get 480 h/s on both cards.
I've set on Afterburner, Core Clock 1200 and Mem Clock 1450 on 4GB card and Core 1200 Mem 1500 on 2GB card.
Afterburner, out-of-the-box, will not let me lower the voltage on the R9270x (probably on the R9280 too) but with this tweak to Afterburner I've managed ot lower the voltage,
