Hello!
I'm mining on HD 7850 (it's about 4.7 CPD).
Anyone tried to use new analog of this card - R7 260X (or another R7 series, there are no R7 in "GPUs supportes" at the first message of this topic).

Maybe you mean R9 270 which is analog 7850 i guess

R9 270 ~ 5,4 CPD (950/1400) Downvolted to 1,0v

Hello, qqqq!
I mean exactly R7. Is it supported with this miner?

I don't have R7. And my results was obtained with Claymore miner.

Hi - Yes it is supported.
I mine with such card R7 260X and it gave me about 3,4 CPD

gollumist, qqqq, thank you for your answers!
hmm.. 3.4 CPD is very small. I thought that it would be the same as hd7850 (4.7 CPD).



The 260X is effectively a 7790 (Bonaire core) with 892SP and only a 128bit bus.

OTOH, the 265 is a what amounts to a 7830, or R9 270LE.  It is a Pitcairn class chip with a 256bit bus and 1024SP.  Frankly put, the 265 has no business being labeled as a R7 class chip and/or in 26x nomenclature. 

If you think back to the 5xxx series, the 265 is pretty much the 5830 where your R7 260/260X chips are the 5750/5770 and your R9 270/270Xs are the 5850/5870.

So, your results are inline with expectations given the 265's bump in hardware resources over the 260X.
