MSI Suprim X: Have 2. One will cause a crash at more than +1000 memory, hashes around 92 only. The other one is perfect at 99-100mhs, 35-40C on 1200 memory -500 clock, 60% PW 60% Fan
Palit Gamerock: 6 of them in total, all run 98-101 at 200W, by far the best card for mining. +1200 mem, -500 clock, 60%, 60%
