Just like the previous miner version, there seems to be something finicky about the SOL/sec rate on the GTX 1080. When I first updated the EQM miner i bench marked 535 SOL/s on my overclocked 1080. I mined at that speed all day, but when I restarted my PC the 1080 only mines at ~ 455-460. The weird part if that nothing changed as far as OC settings are concerned.
With the last miner version, sometimes the 1080 would mine at 505 SOL/sec , but then other times it was ~430. I really dont understand what could be happening to cause such a huge difference, but this tells me that there is a huge untapped potential left in the GTX 1080 that has yet to be fully utilized.
