asrock h110 pro BTC+, celeron, 16gb ram, 120 ssd, windows 10, 5x1080, 5x1070, all new updates and drivers.
when i installed the cards, the first 8 went normal, 9 & 10, system locked a couple of times, had to reinstall but finally all 10 cards show up in device manager. everything looks normal.
no mining software (ccminer, claymore, ewbf) recognizes any cards… even the nicehash software says 0 gpus.
unplug 2 cards… mines like a champ. 9 or 10 = 0.
i’ve been working on this for about 2 weeks. many google searches… anyone got any ideas. is there a bios setting or a windows feature allowing only 8 cards. BitsBtrippin on youtube, has several build videos and it looks like plug and play. am i missing something?
