I posted this yesterday in graphics card section but i realised overclocking subforum would be a better place to put it.

So i was overclocking my XFX R9 290 Black today, using MSI afterburner.
Now i am using an aftermarket aircooler combined with the original heatsink of the card, meaning i can keep the VRM temps really low together with the GPU chip itself even after overvolting.
I had reached a stable overclock with my Core Voltage +100mV and aux Voltage +18mV. Core clock speed was at 1050Mhz and Memory clockspeed at 1500Mhz.
I stress tested 2 hours with Unigine Heaven and Core temperatures never went above 78 degrees and VRM1 was about 81 and VRM2 around 68.Now as far as i am aware these temperatures are totally within limits.
During this stress tested there were also no artifacts what so ever, no crashes or black screens. So i assume it's stable.
Yet when i turned off my computer it black screened right after the Windows 10, loading screen. I managed to fix it by removing MSI afterburner in safe mode and using DDU to remove all drivers.

Now my question is, how is this possible after a seamingly stable overclock? What could be going wrong that it runs perfectly smooth when overclocked, yet when i reboot it doesn't launch anymore and goes into black screen.

Thanks in advance

System specs:
I7-875k @4Ghz
8GB RAM
XFX R9 290 Black Edition
CM 850W Silent Pro
Asus Sabertooth 55i

Wouldn't that also make the overclock itself unstable?

I think i might have found the problem, just not yet the solution. It appears that my GPU is saving it's overclocked core and memory speeds on startup, even when i tick off, apply overclock on startup in MSI afterburner it saves the overclocked speeds. And because it doesn't save my overvolting, and only applies it when MSI afterburner is launched, the computer instantly black screens because it's running high overclocked speeds without overvolting.
At least that's what i think the problem is.
Now how do i stop my GPU from saving it's overclocked speeds even though MSI afterburner is set to not apply overclock on startup?

I just left it stock. A way to do this would be to flash a custom BIOS in which the voltage would be +100mV standard, so with or without OC programs the card would run standard at 100mV more.

If you want to know how i got past the black screen, at startup i hit F8 allot and then choose a boot device, after this it put's me in a windows 10 recovery screen in which i can choose to boot in safe mode. and then in safe mode i deinstall MSI afterburner and run DDU to remove my drivers. After this i can always boot back into windows 10, i do have to reinstall the drivers then
