    Dear Sirs,

    What I experienced;

    4 gpu (1x assus strix rx470 + 3x msi rx470).

    Claymore was showing me 2100 h/s on screen but pool hashrate is 1700 h/s. (after 12 hours test)

    After start use xmr stak, screen hashrate and pool hashrate almost same. (after 9 hours test)

    When I was using 3 gpu (all msi rx470), there was no such a gap between pool and machine.

    there was only memory overclock, from 1650 to 1745. Now I stop this oc as well. Started new test with claymore. But according first hours, still same problem.

    What could be the reason?

    All 4 memory brands are hynix. There is no bios mod.

    Sorry, I don't want to be like in argument. But;

    Why I need to be flash bios, if I did not make any mod? By the way; xmr-stak gpu miner has no same problem. When xmr-stak works well, I try to understand; claymore' s problem.

    Hi,

    As I mentioned before, I stop memory OC. After 5 hrs test. Claymore reports 2100 h/s. And minexmr pool result is 2070 h/s. Seems, claymore runs good now.

    Can I say, memory OC main cause? If I can, why?

    BR

    Sounds like your OC was not as stable as you thought
