I have to use msi afterburner to put my R9 390x at 950 MHz to get stability. If I do not do this, my pc resets when I play games.
What does it means???
What make/model ?.
So,you are downclocking to make it work ?.
What make/model psu.
What is your windows power plan, and CCC power options.
Sapphire Tri-X R9 390X (default clock: 1055)
PSU: Thermaltake sp-750p (750w)
Windows power plan: high performance
catalyst is in the default settings
Won't go into your "bronze" psu.(don't try crossfiring).
Put your card back to factory spec.Un-install afterburner.Then in CCC(see pic)
Try increasing your power limit plus 10% and up(ignore my setting),use up/down pointers to avoid changing clock speeds.
Run Gpu-z(render test)(10 mins. should do, to check temps/volts.(below 11.75v,replace psu(below 12v is,well,your call)).
Some previous gen.cards have required the power increase to function correctly.
If that fails,and your not overclocking everything you got/and running dozens of apps at the same time ?
p.s.My suggestions ONLY apply to 7/8.1....Win 10,forget it (won't use it til they fix it).
I will not use amd overdrive. If this is the solution, then amd should fix the driver.
It makes no sense that the video card requires manual configuration to work correctly.
My suggestion was to possibly rule out a hardware fault.
Partner manufacturers make their own mods to the base AMD specs.
Are the cards 2 x 8pin power connectors firmly seated.
