Statistics on 2F 8 * 1070Ti in the miner 36.5 900mV + 200 / + 200 P0 +
On one riga all 8 cards are the same. On the second 8 cards from different manufacturers. And on the second riga with version 14.1, I got an error 999 with a dump of cards. He rolled back for 14.0 days without errors. But the first rig works on 14.1 without errors.

Magic.
