do you have igpu in your cpu and has the card tried to mgpu with that please?
as for overclocking, I have two of the gigabyte ones that came pre-overclocked at 950-1070mhz boost, the 950mhz should work fine as all three of my R9 280 do that clock.
it should get around 7000+ fire strike score for a single gpu.
anything you require me to do , be glad to help?
Strange. Mine is just weird I guess. I've tried using different secondary monitors as well, no change. Seems to be a card and or driver issue for sure.

Also make sure the card is stable at stock, maintains stable overclocks when gaming and not overheating.
Tried that. Installed 19.4.2 and tried a few mem clocks. 1300 through 1700 all did the same thing. At no load it would drop back to 300/150 until a load was put on it. Gaming it works fine, no flicker what so ever when it runs at 3d clocks. Youtube is pretty much a 300/150 - 500/1250 switch-fest. It will just switch back and forth continually and the second monitor goes nuts.

It does. No change.

I actually tried that. Anything above 015.045.000.010.000000 will not boot. I haven't tried lower revision tho. I guess I could force clock the 2d clocks (assuming it will let me, UVD clocks just revert back when you change them) but that seems drastic.
The only real "fix" I've found would be to throw a spare HD7770 in for the secondary monitor. That seems kinda ridiculous however lol.
*I revered back to 16.11.5 last night. This driver works great with the second monitor. But I'm sure being a 2.5 year old driver doesn't help any with gaming.
