Re: RX580 Benchmarking and Results: 29.3Mh/s @ 77.5W (Sapphire Nitro+ LE)

which bios editor you used??, I used polaris bios editor 1.4.1 but it can't read memory strap entries for my Sapphire RX570 4G Nitro+

I used this fork which seems to work:

thanks it works, sapphire rx470-4g has two kind of memory? memory strap shows 1:xxxx and 2:yyyy

One is for Samsung memory and one is for Micron memory, only one of those sets of straps affect your timings. I believe the 1:xxxx is the Samsung straps by my tests

Yes, I can corroborate this as I have MSI RX580's with Samsung memory and had to use the 1:xxxx straps. I also seen a video with cards using Micron memory where the guy had to use to 2:xxxx, so I think the 1: is for Samsung and 2: is for Micron theory is correct.
