Is there any way to support Hawaii cards (ie: R9 270x 2GB)?
I haven't had much luck finding a linux-based miner that can play nicely with these older cards
SRBMiner-MULTI, PhoenixMiner, GMiner they work at least with my R9 390 8GB and RX 580 8GB cards. Probably there are more but I know for sure these miners work.
TRM I must say did work with my R9 390 but I switched to PhoenixMiner.
But your R9 270x 2GB is way to old to be profitable anyway.
interestingly, they should be marginally profitable at vertcoin, possibly some other algos ($0.20/day/card; and I have these 4 cards lying around unused since 2018.. And living in the North, the electrical heat isnt going to waste!
without buying another mobo (already too many mobos catering to different RAM capacities of individual AMD / NVDA rigs using SimpleMiningOS (SMOS)); I was hoping to use my RX470(4GB) cards
alongside the R9-270(2GB) cards to mine Vertcoin but i think the drivers are substantially different. I can see the GPUs exist but they do not show/accept any clockrates and will not play nice with any of the miners i tested to date.
as FYI:
2x RX470 cards can make ~$2.50/day profit for me
2x RX470 + 4x R9270 can make ~$3.20/day profit for me (and the electrical heat further offsetting my natural gas consumption) so there's a bit of incentive to get the cards mining (plus the joy of seeing old GPUs still having some skin in the game!)
