Title: Expected Mhash/s a bit low? Post by: RainieDays on December 24, 2012, 12:17:48 AM Hi,
I'm new to BC mining and I have a rig with 2 HD 6850s (CrossFireX disabled) running GUIMiner. Both GPUs are GigaByte brand and have been factory OCed to 820 MHz and memory OCed to 1050 MHz According to online sources, https://en.bitcoin.it/wiki/Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison), I should be getting about 250 Mhash/s from a 6850 but currently I am getting only 150 Mhash/s from each of my GPUs What could be wrong? :-\ Thanks Title: Re: Expected Mhash/s a bit low?
