I"m using vega 56 .
These are my oc setting.
I’m getting this much hashrate however , it’s fluctuating. I"m using trm.
These are my oc setting.
Hey,
I started mining today and was able to get up to 180MH/s on my Vega 56’s. They are a mix of factory 56/64 that I have bios flashed to stock 56’s.
I have shown the overclocks and memory timings below for both the samsung (image 3) and hynix (image 4) memory types.
Took me a while getting these dialled in, hope they are helpful!! 
Continuation of Vega 56 screenshots - Samsung memory timings:
I cannot attach the hynix memory timings image due to new member limitations so I will copy & paste both below as well here
Samsung: amdmemtweak --i [GPU_ID_BY_TYPE] --CL 20 --RAS 30 --RCDRD 14 --RCDWR 12 --RC 36 --RP 14 --RRDS 3 --RRDL 6 --RTP 5 --FAW 12 --CWL 8 --WTRS 4 --WTRL 9 --WR 14 --REF 65000 --RFC 249
Hynix: amdmemtweak --i [GPU_ID_BY_TYPE] --RAS 15 --RCDRD 12 --RCDWR 11 --RC 34 --RP 13 --RRDS 0 --RRDL 0 --faw 12 --REF 65535 --RFC 176
Nvidia 7x GTX1660S 6GB
Miner: NBMiner 37.5
440MH/s (6h/24h averaged)
Core: Stock (+0MHz)
Memory: -502MHz Hynix
Power: 502W (PL 56%)
same config as with eth,on eth 220MH/s and 540w Power
What OC settings you using on the 6800? Im only getting 42 MH on mine… my 3060ti are getting 170, so obviously thats not right.
Does anyone have good OC settings for RX6800? Im only getting 42 MH, whereas my 3060ti cards are all getting 170MH. I just switched over to ERGO and i need help with OC settings for the 6800 cards PLEASE!
Thanks man! Made an account just to thank you. Went from like 120 to 180, though i had to switch to teamreadminer… what miner are you using?

No problem, happy to help! I should have said before, but I am also using teamredminer. I haven’t tried any others so you may get better results on NBminer, I’ve seen a few people using that one.
I also found that you can reduce the memory clock down to 920 and keep the same hashrate. It makes the rig a lot more stable and I’ve had zero bad shares the last 24 hours (touch wood).
I guess its just the memory above 1000 that causes the problem. Seems to be ok at 950 right now, thought the hashrate is down to 160 =/ what tuning software are you using in the pictures?
i figured it out, it was just msiafter burner reverting the settings everytime i opened it, though im only able to get close to 180 on 1020 memory

I use RaveOS and it performs the afterclocks in the OS. Not too sure how you would go about resolving that on windows sorry!
Cards, settings, miner, power draw?
Vega 56, settings various as the cards are different brands and memory types. Using custom timings, 900mv aiming for 1400 core. Power draw for the whole thing is 2650 for 11gpus.

Thanks! Any experience with hashrates and power draws on the 64s?
Should be similar, might be a bit higher for less power draw… Who knows…

Hey do you possibly have the settings for amdmemorytweak? highest im able to get is 190 with 1400 core and 930 memory.
good night does this work for RX 5700? I need a good setup for micron memories .
