Good work! I couldn’t get my settings for amdmemtweak to stick with 65535 (at the time), so I moved it to 17500. I apply 890 to both core and memory. I have a couple cards that are showing their age, but to be fair I need to refresh the thermal paste and thermal pads on them before I can pass that judgement. Most recently, I replaced the thermal paste on all of my cards and am seeing a much more stable hashrate. Furthermore, I was seeing a lot of invalid shares, so I bumped the RFC up to 320 without any real adverse affects to the current hashrate of ~44.5-44.6 MH/s.
Soon, I’ll be moving these off to a Cryptonight GPU algorithm for some further testing. My estimates on that algorithm are pretty promising for these cards since CN-GPU is independent of memory speed/timings. I’ve always been a bigger fan of CN algorithm because privacy matters to me a lot more. Sadly, Hive seems to be failing me on getting CN-GPU miners set up properly. Might be back to Winblows until I can figure something out.
Happy Hashing.
