@Marvell2 -- I dont have any CPU rigs. I know that Cryptonite and Neoscrypt can be mined via Ryzen with good results. However I dont think this is feasible anymore because Claymore's latest project is a kickass Neoscrypt miner for AMD GPUs, including Vegas - I am currently testing it and its a winner vs GTX GPUs. I am keeping track with Claymore thread on his latest project. I only have 2 x Vegas64 left after selling 8 Vegas to one of my buddies last month. The miner is driving the Vegas hard at 200w and runs hot.
I haven't really kept abreast with that thread for the simple reason that my 6x Vega rig is "only" powered by a 1500W PSU. Going full beans Neoscrypt (+50% power limit) as per Claymore's suggestions would drive the Vegas a lot harder than 200W actually. We're talking a lot closer to 300. So I'd have to actually lower my PL to mine NeoScrypt on the Vegas, which kinda lowers hashrate quite substantially.
