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.
