Yeah I did not concentrate on tonga cards.
I can reach 430H/s on stock 390X. Or I can try to add Pascal coin to dual miner, or improve CryptoNight miner. Need to select.
This is bad, people have a lot of Tonga cards in hands and wait for speedup for these GPUs
Agreed, I'm hoping Claymore will take care of this and spend some time working on the Tonga chipset. It's really popular and it's been around a long time, a lot of folks run them like you said.
