Re: One rig different GPUs

Mixing AMD & Nvidia GPUs isn't really a problem for the HW, it just complicates managing drivers & software.

There are no problems in Hive OS and similar systems, but you just have to run 2 miners and configure the numbers of video cards in each miner that will mine the required coins.
But of course it’s easier to mine so that the farm mines only 1 coin.

If you mine ETC with PhoenixMiner you can run one instance for Nvidia and AMD. And Claymore's Eth Manager also reads PhoenixMiner's stats.

I think that you understand that the problem is not the mixing of video cards, but the different profits on different coins, so you will have to mine different coins on Nvidia and AMD video cards. But Ethereum classic has long been unprofitable for mining on video cards due to ASICs.
