So far single cards work best. Going to try running separate batch files for each card over night (6 hours approx) and see how it fairs. Seems to be a strong miner for nivida though when it's hashing.
Can you confirm if this works? Is the CPU usage higher with multiple batch files?
Short answer is yes and yes.
CPU usage % fluctuates dramatically 11- 100% given any other applications being used, windows open, broswers, etc. since I'm running video off of the cpu as well. Plus side is I can trouble shoot the cards giving/causing errors, keeping uptime on the other cards hashing perfectly. Since this is a dedicated mining rig and uses only a 960i, I'm not CPU mining with it either. Works pretty well for the application.
Place in the batch file " --cuda_devices X" in reference to each GPU as EWBF's miner relates to it, "0" being GPU 1, etc.
I'm having flawless run time so far, I"ll let run though the day today and see if some slight down clocks on a couple cards will keep from crashing and see if I can up clocks on those that aren't. Once I feel stable I'll try and run a single batch file again for all cards.
