Hey, i just recieved my sapphire nitro+, its a hynix memory and I'm trying to figure out what modifications should i do to get a better hashrate, i started with flashing my bios to anarok's mem strap bios version, it went up from 22 mh on 120W to 25mh on 110W, is there anything else i can do to get a better hashrate? I'm kind of new to mining so if there is any guide i can read about memory strapping, under volting or overclocking i would appreciate it, i tried searching on the forum but i got nowhere, probably using wrong key terms
On *solo* mining ETH you should be getting 28+ with that card. Don't stop until you are. Google it, search the forum, it's all there. Also, install GPUz, and go in the settings/info page to make sure your ASIC quality is above 70%. I got all mine above 80% by returning, rebuying, but it's a pain. You get more stability with undervolting if you have better asic quality. Don't install other bios. Just do your own with polaris. Takes a few seconds. Flip the card bios into the side facing the monitor out (slow mode bios by default), and use ATIFlash (orWinFlash) to save a copy. Back that up, then copy/paste the file and rename to "modded." Open it in Polaris, copy the 1500 line, paste values into the higher lines, then ATI that bios back to the card. Reboot once or twice. Then use afternburner to -100mv (AB will show as -96), underclock core to 1100, and overclock mem to 2000. With that much undervolt, it'll crash once a week, but I have scripts to make the system reboot and restart mining within 2 minutes flat. Worth it for the energy savings at -100mv. Once in a blue moon have to set -100mv again in afterburner if a reboot caused it to lose that setting, but it's easy peasy lemon squeesy with teamviewer mobile app. No harm whatsoever to occasionally crash and reboot with -100mv.
The rest is on you. Learn, read, study, try, fail, try again. Good luck.
