Avalon 741 losing hash rate?

[nu1mlock]

Hi,

I have four Avalon 741's and whenever I mine something other than BTC/BCH they basically just mine at 2/3 their speed.

I'm going to assume that it might be because of rejected shares (I get lots when I don't mine BTC/BCH) but if that's the case, is there something I can do to remedy that?

I've already tried to increase the difficulty, in case that was the issue, but it didn't help.

Any ideas? Do you need any info from me?

Thanks!
