Best BIOS ROM for Sapphire Nitro+ RX 580 8GB Special Edition Hynix Memory 31+ MH/s

Here is another BIOS long waited for most of you, but thanks to Igor i was able to test the Sapphire RX 580 8GB Special Edition remotely via teamviewer. I must say that the Special Edition GPU is awesome, just like the Limited Edition and Nitro+ with great hashrate, stability and undervolt control.

I didn’t had an energy meter to check power consumption from wall, but based on GPU-z reports i can come up with something very close to reality.

In this case, for some reason I wasn’t able to set the clocks via .bat file and I had to split the commands. I set the clocks to 1130/2150, undervolted the GPU to -100mV via MSI Afterburner and added –mvddc 900 to the .bat file.
