I have 6 xfx 470 4G, was running 158.
I try the beta one, and my experience is:
I modded the cards, set the gpu voltage to static 930 all stages, but when running Claymore, the voltage up to ~1080. I could not understand why.
+ Claymore cannot control voltage and frequency of both gpu and memory.
+ Claymore 9.7 can run 28 each card, resulting 168 MHz in total, can not control fan + temp
+ Claymore 9.8 can also run 28 each. It can control fan + temp
I try AB beta, it helped to to reduce 3 first cards to ~980 mV, and 3 remaining to ~880 mV. I could not understand why there is a difference between 2 card groups, because physically all 6 cards are the same: same version, same bios. All cards show -96 mV in AB.
+ I tried many way but cannot reduce the first 3 cards to 880 mV.
+ I could not also reset all cards to 1080 to try again.
Removing & reinstalling everything (driver, AB) does not change the situation: 1080 mv then down to 980 for the 3 first cards, to 880 for the remaining.
So now I run all cards consistently, but 3 with 980mV, 3 with 880 mv. Very stable,
but not happy because I want to reduce all cards to 880, or keep 930 mV untouch in the Bios setting.
Anyone has any idea?
