System specs:
Windows 7
Intel 990x 1366 socket
24 GB RAM
1300 watt EVGA PSU (Brand new)
2 Nvidia 1080 TI cards
1 AMD Vega Frontier
Nothing overclocked
CPU and GPU are water cooled, temps well controlled
Nvidia driver 388.0
Windows up to date.
This machine is used primarily for distributed computing (BOINC). I recently upgraded an RX 480 to the Vega Frontier, which I got used. Before upgrading I had a 1080, 1080 Ti and the RX 480. That setup was 100% stable. When I added the Frontier card I also replaced the 1080 with a 1080 Ti. The Nvidia cards are 100% stable.
I have two problems which are probably related. First, I've used either DDU or the AMD driver removal tool before installing new drivers, and I've tried almost all of them that AMD has released in the last year. No driver shows Wattman controls, except for the current 18.Q4.1 which does show the fan control, but nothing else. 3rd party tools like OverdriveNTool and Afterburner show the controls for clocks etc. but don't allow me to change anything. Overdrive gives an message about the function isn't supported by the driver.
The main problem I'm having is under compute load, Vega Frontier locks up the system but doesn't usually give a BSOD. I've let the machine sit idle after a crash for 8 - 9 hours before without it giving a BSOD. The one time it did, the message said the driver was in an infinite loop. If audio is playing it will continue to play normally until it's finished. This may happen in a few minutes or a few hours. When it happens Windows won't see the card unless I power the system down.
I have tried almost every driver released in the last year. I've tried swapping power cables from a 1080 Ti, which has been 100% stable. Since I'd have to tear into the loop to more significant testing, like swapping to another PCIe slot, I was hoping to get an opinion on if it's a Windows 7 problem, driver problem specific to me (perhaps conflict with the Nvidia cards) or a faulty card.
