My 7 card machine has been stable for a good couple hours now on 0.6 at Flypool using two instances. Four Hawaii cards on one, two Tahiti and one Pitcairn on the other. Huzzah!
which card are?
which driver?
which windows?
Three reference 290s with Stilt bios (one Elpida, two Hynix), one Elpida 290 Windforce flashed to a 390, one Gigabyte 7970, one Gigabyte 7950, one Asus 270X TOP. 16.1.1 using 16.10.3 dlls, Win 10.
The machine is still not hashing at full speed - I'm suspecting a bottleneck at the CPU, the slowest Celeron I could get for it. Board is a Z87-G45 Gaming.
