Title: HASH rate not as expected Post by: tommywommy on March 27, 2013, 02:42:29 AM Hi, I'm running 2x5850 vapor-x (obviously not in CF). Using GUIMiner. My hash rate is combined 400 MHash/s (204MHash each). Isn't this a little on the low side? Table (https://en.bitcoin.it/wiki/Mining_hardware_comparison) reads 270 at least (and mine is factory overclocked). I've not OC past factory, so why is this low?
If it helps my proc is q6700 @ 2.66, my environment is windows 8. Any suggestions? P.S: Unrelated, but my MHASH dropped to ~ 400KHash/s and I had to restart the miners. Any idea why this happened? I'm leaving my system on tonight, hope it doesn't drop while I'm sleeping. EDIT: Found this, but it's not helpful: https://bitcointalk.org/index.php?topic=145265.0 Thanks Tom Title: Re: HASH rate not as expected Post by: tommywommy on March 27, 2013, 12:43:01 PM does bumping work?
Title: Re: HASH rate not as expected Post by: Gator-hex on March 27, 2013, 12:48:08 PM Use catalyst 12.11beta drivers from you cards manufacturer, disable crossfire, and overclock using catalyst overdrive.
I recommend mining on 50BTC or BitMinter pools. I get 260MH/s on 5830s you should be beating that. Title: Re: HASH rate not as expected Post by: tommywommy on March 27, 2013, 01:26:57 PM that 260 hash is on OC?
Title: Re: HASH rate not as expected Post by: Gator-hex on March 27, 2013, 01:42:51 PM Yeah, just a slight overclock, no voltage mods or anything that could harm the cards, though some people claim to get them to 300MH/s
