I just installed the 17.10.2 driver for my Vega 64 x 2 and R9 290 system. It does have the DAG performance of the blockchain driver and I can easily get the same 44Mhash per card. I can also undervolt... to a point.
With the blockchain driver voltage control was lacking, yet applying a registry tweak and using OverdriveNT allowed me to achieve 44Mhash at 0.8125 vcore and 130w power draw.
I can't get my vcore down that far with the new drivers. The lowest I can go is 0.92v. I've tried fiddling around with the core clock, leaving the voltage on auto, changing the power limit, changing the voltage to manual and putting the core voltage and memory voltage at various combinations. I've tried core/memory voltage combos of 850/800, 800/800, 800/850, 950/900, 900/950, etc. Nothing works. OverdriveNT does not work. Applying the registry tweak makes my computer not boot into windows.
If I leave the voltage on auto and decrease the power limit to -45 and the core to 1000mhz, I can get to 0.92vcore. I can also get to 0.92 vcore by lowering the voltage manually and then applying a -45 power limit.
Any ideas on how to get to lower voltage with the new drivers? I'd really love to be on the latest driver chain again so I can play games too.
