I seem to be having a high hardware error rate and a high invalid share submission rate. 7600 hardware errors in 1.5 hours, 93% efficiency rate, however the mining pool still shows over 200GHS from my worker. Is this normal? I am used to 1 or 2 hardware errors a day and much higher efficiency when GPU scrypt mining (on the same pool).
The status page on a lot of these miners are hit and miss as far as calibration is concerned.
I just let mine run for 10 rounds on my pool and go by whatever it says just like your doing.
