Yes. But, you don’t need to reflash the bios. All it does is to change the power play table values in the registry. Perfectly reversible. 5000 series has red bios editor that can flash the bios, but I’d much prefer to keep the stock values.
Two values you need to change is the Power Limit GPU and TDC Limit GFX under power and voltage. You will have to find out what is the max voltage 5600XT can take and back down a little. Mine is 330W/350W typically, but I pulled back by 10W not to push the limit.
What’s been surprising is that my card actually pulls less power after the mod, and runs cooler with less voltage. Also all the mini stutters and pauses are gone, and I feel like the card is breathing better.
I am not sure if this is AMD’s driver issue or HP’s ridiculous power draw or Asobo’s software bug, but hope they can fix this soon. Give it a try and report back. I’d like to report this to ASOBO/MS developers.
