Combined rig with 6970 and 7970

[Frizz23]

Hi,

I already have a host with two 6970. Now I am about to get a 7970.

Question: What Catalyst, what SDK version to use for such a 6970/7970 combination?

As for the miner: I plan to run the 6970s on CGMiner, the 7970 on DiabloMiner.

cheers,
F.

OK, so summarized:

- don't use Catalyst 12.1 (it's the newest driver!) - since it won't show the 7970
- download 8.921.2 RC11 AMD Radeon™ HD 7900 driver (amd_radeon_hd7900_win_64.exe) instead - and pray that you still see your old 6970s.
................... btw: AMD sucks balls! pure driver hell  
- 7970 should be in PCIe slot #0. Use "cgminer -n" to get details.
- SDK 2.6 sucks - but it's needed for the 7970.
- keep old .bin files (pre SDK 2.6) to use with your 6970s.

According to Micah Villmow / AMD with Catalyst 12.1a preview it should be possible to run 6970 and 7970 in one host.

But this posting also states that the 100% CPU load bug is back. *grrrrrrrrrrrr*
