Thanks for all the feedback, the Gen 1 setting in Bios worked and I can get past post but with only 5 GPU's. After some testing, I think one of the 480's just does not like risers since it works fine in another PC on the X16 slot. Anyway, I installed Win10 and it sees the 5 cards, less the flaky one that does not like a riser. But now when I start claymore, the display driver crashes and thus crashes Claymore. Using AMD 16.7.2 driver and Claymore 6.2 BETA.
Anyone running the same versions of driver, claymore, BTC Pro MB and 480's?
Have you tried the 6xGPU Mod?
https://lbr.id.lv/6xgpu_mod/6xGPU_mod_download.htmlIf worked for me with Win7, 6 x R9 380X and 15.12 driver.
I don't know if it works with Win10, RX480 and 16.7.2 driver.
Win10 should support 6 GPUs anyway.
Regards!
