@vh I don't run Windows, my data point is Linux (Ubuntu 18.04)
@os2sam just another data point. With the new build (8e62f0b)
On my Ubuntu 18.04 low power celeron 1.83GHz x 4 box:
my R606 at voltage level 4 and 575 MHz
I am seeing 780 GH/s right now connected to ViaBTC.
The previous build would not get all three GSI units up to 575. I would see something like 568/568/568 ...
Very happy with the new build on linux anyway. Can't speak about Windows performance.
Also, on the Ubuntu box I do have to run with --gekko-lowboost , leaving off that option will cause all GSI units to eventually go offline.
Likewise, I reloaded my Linux box to Linux Mint 19.1 Tessa Mate 64bit edition. Took a bit to get xvnc to work properly in order to remote into it. But holding strong on volt 5, at 725 Mhz averaging at 973Gh/s per unit. I have one that is being a little troublesome that requires a little more testing. Believing to be a weaker chip possibly in the unit. As at this Mhz and volt setting, one of them eventually will drop on the work % from 100% down to the mid 80s and then status changes to DEAD. I do not believe it's thermal related as I have plenty of additional fans on the unit with a push/pull setup and room temp of 74 degree's F. May have to either lower the settings or give the --gekko-lowboost a try. As I had forgotten about the low boost option.
