I am having a issue with monero mining on claymore where I get "Lowdifficultyshare" I have set my -a and my -h but still get the error and I have switched pools and drivers and claymore versions and still nothing. I am mining with one 7970 and one 7950.
I was getting the same errors right after switching over from mining ETH with Core/Clock speeds set at 1150/1950 (strap-1500 modded 470s). After seeing this, I went it and changed from 1150 to 1200 and have not seen that LowDiffShare error since... over 24 hours ago. Of course, upping to 1200 sucks more wattage but also gives a bit more hashes and no errors... and still my 6-card rig is at 830 watts, but 2 of the GPUs are not strap modded yet so after that and a bit of tweaking, pretty sure I can get it back in the mid 700's wattage wise. So, bottom line... try upping your core speed a bit and that should get rid of that error.
