Title: Combined rig with 6970 and 7970 Post by: Frizz23 on February 09, 2012, 09:26:53 AM 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.

- 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.

See: http://devgurus.amd.com/message/1278533 But this posting also states that the 100% CPU load bug is back. *grrrrrrrrrrrr* |
