On a vega 56 do this for near 47 mh/s rate:
Memory clock at 950 mhz (yes even if you have hynix memory. I have a large quantity of samsung as well as hynix reference cards working at this frequency just fine).
Turn your core voltage down to 835mv and your core clock to 1000 mhz. Throw in your own favorite amdmemtweak settings (–CL 18 --RCDRD 12 --REF 15000 for samsung and --cl 18 --ras 23 --rcdrd 22 --rcdwr 11 --rc 34 --rp 13 --rrds 3 --rrdl 4 --rtp 6 --faw 12 --cwl 7 --wtrs 4 --wtrl 4 --wr 11 --rfc 164 --REF 15000 for hynix memory)
If you’re running hive either off of the vega image or the beta, it doesn’t really seem to matter including their different 19.10 and 19.30 drivers respectively; so have faith and remember to apply aggressive undervolting AFTER you have applied and hive has completed your oc settings.
Now start your miner and with AU now applied you will most likely your vega tach lights (for reference card models) will show 3 steady red lights instead of the full five. This is what i run and its by far the best quality of hashing (i have 4000 accepted shares for every 1 invalid share), best reported hash rate and best compromise I’ve found for power draw since the fucking utility companies are what suck out most of our profits due to expensive electric rates.
Ive fucking scrapped, cried, broken shit, cried again, pathetically wallowed, wandered through at least one spiritual and one existential crisis all so i could share Ted’s secret stock Vega 56 parameters. I stand on the shoulders of the hiveos devs, the teamredminer devs and the coolest dude of all… the guy whose name i cannot remember that created andmemtweak and like a modern day Prometheus, decided to take his very valuable code and give it away for free. Its through his own example that I share my small amount of vega mining with the rest of you. Hash well and ill see you on the other side of Eth 2.0 where I’ll be running a Cardano stake pool and cheering for ethereums ultimate terminus.
