Well for ethereum that may work fine, but I guess for Equihash - that has more core demand - the settings may not fit so well, especially the low voltage. Try to go for 1200 / 1850 at a slightly higher core voltage (-100mv vs stock may be good point to start) . Ethereum is not sensitive for memory and regist bits flipping - that may cause the one or other hash to be invalid, but its a rare occurrence. In Equihash one defect bit can cause the miner to stuck, because its more using data dependent loops.
Nah, doesn't work.
I've been trying different settings for the past half an hour, all failed. Now the miner gets stuck even sooner, after listing all the gpus.
I think it just doesn't work well under Hiveos and that's it.
