using a spare GPU 0 to improve hashing
« on: February 03, 2014, 02:59:37 AM »
On my 3x7950 rig I get ~5% reject ratio when all 3 are running and they run at about 600 kh/s. However, when I turn gpu 0 off the reject ratio drops to ~1% and the hash rate raises to about 620 kh/s. This is independent of which gpu I have as the primary one.


Does anyone else notice improved performance when gpu 0 is turned off?


I'm thinking of putting an extra gpu in my rig so that I can get the others to run better, but I'm not sure if it's worth the extra space/energy requirements.
