With SRB Miner 1.6.4, my Vega FE rig is currently doing a stable 11060 H/s. Each Vega FE gives a minimum 2205 H/s and a maximum of 2222 H/s, each card is slightly different as you know. Now the temperatures are between 58 and 60 C, only one card rarely goes to 61 C and then gets back! So I think this is pretty cool. I set memory clock of 1100 MHz and memory voltage of 810 mV for all of them. I set slightly varying core clocks however as each one behaves slightly different but generally it is in the range of 1502-1552 MHz and core voltage of 950-1000 mV.

Using OverDrive when I had Blockchain drivers, I could set core clock to 1600 MHz and core voltage to 890 mV which is weird, memory was 1100 MHz along with 880 mV, this would get me 10910 H/s (even with SRB Miner 1.4. with slightly higher (extra ~5 C) temperatures. So I'm not sure if the rig is consuming more power now than before, but extra 160 H/s must be mostly related to SRB Miner 1.6.4 and the new drivers.

I also noticed fan readings are jumpy at times both in the WattMan and the SRB Miner so this must be sensor readings from the driver or maybe really the fans are aging already. These hashrates that I've mentioned are for CN7 only.

Thanks for the great Miner! I think some extra features may be handy and will dig it later.
