Howdy folks,
I was asked by Hellae to try mining Monero on my new Threadripper 1950X + 4x Vega FE build. Well, I'm new to mining in general and probably am missing some optimizations, but here's a screenshot of xmr-stack-amd mining on the 4 Vega cards only:

Getting about 4800 H/s at stock.
I read earlier in the thread about needing to enable HBCC? The crappy thing is, Wattman is only installed with the intial release 17.6 Vega FE drivers from June 26th. Neither the blockchain drivers or RX Vega drivers include Wattman, so I don't have any of those options to change frequency, voltage, power, etc with the FEs unless I install the 17.6 drivers.
Any tips?
EDIT:
I reverted to the 17.6 drivers so I could undervolt and enable HBCC, and getting 6460 H/s now at 1602 Mhz core and 945 Mhz HBM clock. I guess the remaining 1600 H/s I'm missing is due to me running the 17.6 drivers instead of Blockchain? And perhaps the stock clocks?
Finally someone with Threadripper and four gpu builds. What is the temp? Do you use risers? I was asked by Hellae to try mining Monero on my new Threadripper 1950X + 4x Vega FE build.

That's why I called him here for... science! We need FE's tested with all the new discoveries here.

No risers... but 128 DDR4 and 16Gb HBM2 per GPU will allow some cool tests on HBCC, I HOPE.
Yep, I got HBCC enabled and with the slider set to max (80-something GB) my hash rate hit almost 6500 H/s with the four Vegas. I haven't tested the 1950X yet... its temps reach almost 70 degrees with the Corsair H100i v2 so I'm waiting to test anything else on that until I get it into my water cooling loop.
I didn't monitor my temps while running the miner, but when maxed out during the LuxMark stress test, the core temps stabilize in the high 50s with the HBM2 and "hot spot" reaching high 60s. This is on watercooling with only 2 280mm rads -- I hope the temps will come down after I added another 280+120 rads. Even now, I'm not hitting any thermal throttling so my 1602 Mhz clock is solid after a slight power budget increase.
