Doing “amdtweak --REF 65535 --RFC 300” at 1075 core 1107 mem was able to bring a few of my cards up to 45mh/s. Thank you GearheadNY for that.
A few of my cards have needed 900mv instead of 850mv to run stable, and a few of them have required slower clock speeds. The worst right now is getting 38mh/s at 1138/1028.
I tried using the B and C modes on teamredminer and I saw no difference in hashrate. If anyone has been able to coax more out of these cards I’d love to hear how you did it! I also bought these back in 2017, falling victim to the marketing that these were supposed to be good for blockchain applications.
