This is by far the best settings I tired.
4x Vega 64 with waterblocks.
Core
1300@0.950V and
1100@0.95V Normally it was 19.24kH/s/Vega. After the timing set is about 21.85kH/s/Vega.
Max temps: Core 40*C, HBM mem 53*C.
Team Red Miner v0.4.3 L22+22. HWinfo GPU chip power 157W. I don't have a power meter.
almost 4h no errors.
https://ibb.co/R7CWKjwvega64 lc is happily mining 21.2kh/s with 1230/1090@800mv showing only 115 watt in HWinfo GPU chip power
I will get to that eventually.
For now I'm testing other settings.
On normal timings the best intensity was L24+24. at the same core/mem freq I had consistent 19,24kH/s on all cards +-0.05kH/s.
On new timings this intensity was not that stable. After that L22+22. After 4,5h of hashing first HW error showed up and speed was 21.85 kH/s but with the spread od 0.4kh/s betwen cards.
After that I have tested L20+20 but that was ruled out because of decrease in hashrate of about 0.5kH/s/cards.
Now I'm using L18+18 and got result of 21.83 kH/s +-0.03kH/s between cards.
Using Adrenalin 19.4.1.
Please, can you write, in a few lines, how yo uset up your rig with 19.4.1, are you using power table, odn tool, if not, what you do? I tried 19.4.1 but frequencies are jumping all over the place, hbm goes from 1100 to 800 and 500 and this drops my hashrate. I returned to 18.6.1 and then it works ok. Thanks!!
