V3.1 stable on all machines except one, which is a 7 card rig. Few minutes in one of the GPU's ( always at index 1) would report 0 sols/s, the watchdog will restart the miner, and "Desplay driver stopped working, has recovered" error pops up, and then the system just crashes.
Some people pointed out that it could be a riser issue, but I've tried isolating the faulty card by running each card on its own thread, and they work fine. Its only if I run one instance of claymore's with all 7 cards that this problem occurs. I've tried moving from modded bios to stock, different driver versions, and this keeps happening still. Any clues?
The same thing here. I got all rigs except 1 working with v. 2.1-3.1 with -i 2. The problematic rig has 6 R9 390 which work about 20 min with 60-ish sols (and over 1% rejected shares) then 1 card stops. Curiously, with -i 0 there is no problem and the cards give 70-75 sols! I tried everything but it is not the card nor the riser.
