Pre-owned RX 580 came with unstable overclock

I recently bought an XFX RX 580 GTS XXX Edition from eBay. When I installed it, I realized that the screen would flicker every few seconds. I opened AMD WattMan to find out that the card came with a core clock of 1405 MHz, which is above what's listed on XFX's spec sheet (1366 MHz stock, 1386 MHz OC+). I turned the clock down to 1366 MHz, and everything was stable. However, problem is when reinstalling Windows or using Linux, which is when the underclock is inactive. Is there any way I can return the card back to stock speeds without the usage of WattMan?

Make sure it's in the first BIOS, not the second BIOS. You can toggle between BIOSes with the BIOS switch on the top of the card

Forgot to mention that in the second BIOS mode (switch pointing towards the video outputs), it just shows a purple screen on boot.

Sounds like the card got overvolted to death, I doubt there is massive amount that can be done if the card is degraded. Downclock it to 1300MHz and see if it's stable, and maybe look for a refund.

Yours faithfully

As I mentioned before, the card is stable with 1366 MHz. I've played several games on it and it hasn't had any abnormalities. I just want to permanently restore it back to stock speeds.

Derp, I forgot to mention to do it through a custom (or, stock I guess?) BIOS, there are guides online on how to flash video BIOSes

 

Yours faithfully

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad
