Thanks Kaap
I'm happy with the clocks but it sucks being in the 60-club.
Tested in nearly every game/benchmark I could as you do. 3D Mark 2013 was the only thing to crash practically straight away beyond those established stable clocks. Heaven was more forgiving but my case got very warm. Summer is a terrible time to push GPUs
Voltage and power limit was maxed then screen froze leaving Nvidia display driver to recover, took it from that the chips were limited to those clocks. Nothing more I can do to push towards 1500MHz, no want to even do that on stock cooler because heat in SLI could become an issue.
Anyone with a MSI 980 TI Gaming flashed their card here? Read on OCN modified BIOS's were too noisy and huge increase in heat (sometimes boosting was too high and crashed out), the ones I read about all flashed back.
