Topic: Not fully working cards (only 70%) (Read 1010 times)
Temps are 72 for main one and 62 for other. Difference between f2 and f16 is 15 MHash (430 vs 415 if card is working alone). Thing is that even with both card set at f16 Im getting lower values. Cant get main card below f30 or they'll both throttle down. (If only one card is working f0 is fine)
maybe GPU overheating and throttling ? what GPU temps during mining ?
note: lower "-f" mean more GPU saturation. so "-f2" in you case is really hard saturation[basicly IMO, going under "-f8" isn't safe on some drivers combinations[GPU/mobo/CPU/storage drivers and some appz], so try check/improve GPU cooling and stick with something like "-f16" or around.

Have new problem.
Added second card to my rig. Now have 5850 on PCI-e 16 and 5870 on PCI-e 1. Cant change places of cards, cuz getting lower hashrate if 5870 is in higher slot... Even now I have to use higher -f values (-f40 for main card and -f2 for second one), cuz otherwise main card is working at around 60% and other around 90-95%. Any idea how to solve it?
