@crutsy yeah 12 is ok to set it at, I have the same CPU and use 12, reporting is Threads not cores a 12 Core would be 24 Threads. I get about 10,000 nonces per minute.
@neatcrypto-com The version windows uses always comes from IE so updating that may get rid of the error. I tried to do all my updates and it still didn't help the error though.
