After 2h5m no rejected
impressive!
Thank you! After filtering for a few random rejected shares due to new jobs there shouldn't really be any rejects though, so we're just where things should be
.
Also, the kernels are designed to handle a downclock of mem all the way down to 300 MHz on Polaris cards and 500 MHz on Vegas, this without hashrate being affected. It probably won't save more than 1-2W per gpu, but always something.
Lower mem clocks on their own don't do much for power use, because the true mem voltage is static - set in the vbios. However, you can actually save some pretty significant power on vegas if running mem <= 800, just by disabling mem_p3. p3 only scales down to 1107 SOC, while p2 will go to 800 (maybe less - haven't tried,) and a lower SOC allows lower core voltage.
I've not seen similar SOC clock/voltage design on polaris, so don't think the same can be said for that platform.
