Hi All,
Recently i got 12 vega 64's and mining xmr on cast miner with blockchain drivers.
I tried using every video + articles tweaks to make my vega power efficient at the same time hash more but almost every video tweak ended up dropping my hash rates from 2020 to 2000 or even further between 1990-1950. 1st card - 2010-2020, 2nd card 1990-2000, 3rd card 1950-1980 and so on.
Allthough all my cards having the same wattman settings and vega registries configured (got them downloaded online) yet all aren't staying stable at 2000+ hashes. I can understand that 1 card always performs less then the rest but considering all cards defer in hashrates by 20-50 is really frustrating to see when one pays 500$ per card.
I eventually ended up tweaking with my own settings and i achieved hashrates between 2050-2070 with lowest being 2020-2030 (last card in series) but this was possible only after increasing the power limit by 15% and now my total power draw is 1950w
even though the vega's are hashing above 2020.
I even reached 3000+ hashes per card but with errors.

My wattman settings :
Clock
min1262 max1407
Volt
min1150 max1150
Memory
1100Mhz
Volt
850Mhz
Fan
min3500 max4900
Power limit
+15%
My concerns are :
1 - How long my cards with above tweaks would last as the temps are between 70-75 degrees C. Are these temps safe and normal for the vegas & HBM ? What are the safest temps for vega to last 2+ years ?
2 - Does anyone has any settings that can yield higher hashes then 2000 or 2020 + with lower tdp's ? (I tried the youtube videos settings but failed to keep the hashes stable even though tdp & temps were under control)
3 - Lastly does limiting the temperature settings in wattman to min 40 max 55 or any other figures would cause the vegas to crash/malfunction/deteriorate as it restricts it limits to go at higher temps ?
Note : I know that vegas perform better undervolting unlike other cards, but this trick just doesn't works with stable 2000+ hashing in my case.
Any suggestions are highly appreciated, pardon if my settings are noobish.
Thanks.
