Mining ETN at nanopool with RX580 8GB , intensity 60 on each card 890h/s! Is there anyway I can further tweak it or that's the maximum? Do you guys have some BIOS mods for RX580 Sapphire Nitro+ Special Edition's with Micron memory for cryptonight algorithm? I am currently mining it with my ETH, which may be causing this not optimal speed.

MSI Armor RX580 8GB - Micron, using one click patch timings in Polaris Bios Editor.

Getting 1010 h/s using:
Intensity: 51, threads: double (Constrained by the Virtual Mem Size, out of space on SSD, could be higher)
1160 cclock / 880 vcore
2220 mclock / 880 vmem

Double threads are very important, it increases occupancy. Make sure you have sufficient vmem space, check out vmem usage using HWINFO, make sure there's at least 10% free vmem left during mining.

Microns are good, I like'em. One click patch timings in Polaris is very good for ETH mining (31-32 Mh/s) and it's possible that there may be timings that will take one to the moon at 2100 mclock catered for Cryptonight, but I don't want to play with BIOS everytime, it's really stressful because I'm afraid of bricking cards, so not going to touch'em for now.

Also, you need to close gpu-z or hwinfo during mining, it slows down the mining slightly but the losses would accumulate over time.

I modify strap from Polaris bios editor one click timings with cclock 1240 and mclock 2150 CN-V7 got 1010 h/s and CN-Heavy got 1080 h/s.
if you like to try I will post my strap here. with your card which can set mclock 2220 most likely can reach CN-Heavy 1100 h/s.

Thanks! I don't want to flash anymore as every time I do it I get shivers down my spine Cheesy

But here's one thing about flashing, two of my cards failed flash... Bios write failed multiple times, gpu's no longer listed as AMD, bios read was not even working. Then I continued a few hours of operation with other gpu's, reading about fixing bricked cards, and then they literally fixed themselves, with the original bios. I don't think MSI Armor has dual bios so I don't know how that happened. You guys have any ideas??

Maybe if I increase the Core clocks to 1240 it'd do 1050-1100 but it gets too hot and I have to crank up vcore so I think I struck a nice balance here, will try those after I get the hardware cost covered lol Cheesy
