Running Windows 10.
i7 9700k
DDR4 RAM
Gigabyte Z390 motherboard
Original PSU is Corsair Hx650 (idk if gold or platinum)
New PSU is Corsair Hx850 platinum
My one Vega 56 is a powercolor, the other is a sapphire
I've previously created This thread over at amd forums but the solutions offered there did not solve my problem. I have now tried two different Vega 56 graphics cards and it happens to both of them. The screens go black - or whatever color was most prominent on the screen at the time - anywhere from 4 hours to 3 days after booting the computer up. I've never had it last longer than 3 days in the past 4 months.
The original thread that describes my problem pretty much to the T is RX Vega64 Liquid -- Possible HBM2 Downclocking and I've been unable to implement the solutions of downclocking the HBM2 using the new wattman.
I've tried the following:
Swapping a new vega 56
Flashing the bios to vega 64
Flashing to a different Vega 56 bios
Using old drivers
Using the newest adrenaline drivers
Using the Professional series drivers found here
Changing the core voltages using the GUI (wattman?) to the following values:
+ Change the State1 core voltage from 991 to 1000.
+ Change the State7 core voltage from 1200 to 1162 (or 1175).
+ Change the State7 frequency from 1630 to 1600 (or 1590 or 1580).
I've found no solutions for this problem. The computer crashes and leaves a blank screen no matter what activity I'm doing, whether its playing games or idling overnight when I fall asleep watching netflix. It isn't overheating, I've logged the temperature and it is never over 55° and even that is quite high for what I'm normally doing.
If you have any reasonable suggestion, please shoot it my way and I'll give it a try. ty for reading.
