What's the highest hashrate for 280x with private kernel at this time?İf it's effective possible to buy ))... i have 25 280x for gpu mining.
I'm currently running 501MH/s, it's 280x @ 1140MHz.
If you can run higher clock, just multiply the hashrate.. It is directly proportional, because this algo uses no memory. Memclock can be set to lowest you can, hashrate is not affected.
