Hello all, and thanks Claymore for new miner version!
Though, I have a problem and hopefully one can help me about that.
I got several rigs of 3x470, 4x470 (4 GB) and 4x470 (8 GB) videocards.
After updating the Claymore ETH from 7.4 version to 9.0 I got a strange problem.
Decred increased *2, that's a fact, but hashrate of both ETH and DCR became floating. Usually my cards give 21 or 24 Mh/s (nothing is overclocked/modded, all stock) depending on whether its Asus strix 4gb or Sapphire nitro 8gb, but now once in several seconds one or two cards in the rig drops hashrate to 17-18 mh/s on eth and to 400 mhs (instead of usual 600 mhs) on dcr.
Added to OP:
- AMD cards: On some Polaris cards you can notice non-constant mining speeds in dual mode when ASM mode is used; you can also see in GPU-Z that memory controller load is not constant, it drops for a few seconds.
This issue is related to hardware and I cannot find any good workaround for now. Try to increase "-dcri" value a bit, it will reduce ETH speed a bit, but speeds will be much more stable.
