Hey,

So here's my problem, I own several rx480/580 4GB and I used to be able to overclock the memory to get better mh/s for ETH.

However NOW, OCing the memory has NO effect, 1700 or 2250 has the same hashrate, Biosmoding has no effect on the hashrate aswell. WTF!

So I was getting 28 mh's with OC on 480 4gb samsung mem. Now I'm getting 25 with and without OC or Biosmod or both.

This is what I tried:

DDU uninstaller/reinstalling everything except OS
Older drivers
atikmdag-patcher
Extended overclock limits in MSI AB (worked for a short time, I always had max mclock without setting it, and couldn't change it)

Now I'm not using these in a mining rig atm, so I'm guessing it's either a setting in bios that forces stuff OR the OS (using win 10.

Anyone can help me with this?

So... since the bios sets the clock speeds, if after flashing the bios you're getting WORSE than overclocking that means you're not flashing the proper settings.

28mh/s is pretty good, I'd suggest trying to flash the cards (individually) again and double check all of the settings
