Combining AMD GPU's in miner

[Jos-T]

Hello all,

Because of power usage I would like to combine different cards in one rig.
I read some stuff about it on the internet, but I can't find a definitive answer.

Is it possible to use a R9 270 and a R9 280X in the same rig and have cgminer configure the cards seperately?
Will installing the drivers give me any problems?

Thanks in advance!

I have a rig currently with a 7970 and 2 R9-270, soon with 2 more cards. Of different brands.

I have no problems configuring separately, for scrypt. I had a few issues mining Vertcoin, sub-optimal performance either on the 7970 or the R9-270's.

Install Catalyst 13.12

You do have a point. It can be convenient to, for example, have "3 and a half cards" on that 1 KW PSU ...
