Hey,
All night I had average 279.383 h/s with my amd radeon r9 280x, but 2 hours ago decided to try how another pool ( https://zec.nanopool.org/ instead of https://zec.suprnova.cc), restarted Claymore and speed dropped to 211 H/s.
So I restarted Claymore again , now with original Supernova bat file… but speed is still low - 211 h/s.
I didn’t change any settings, what could cause such drop?
