980 Ti memory downclock?

[OhMyHolyToken]

Hi,

I'm trying to optimize the performance on 980 Ti for ZEC mining.

Each 980 Ti with 1.043v and the clock around 1300-1320 with power limit on 70-80% produce 450 sols and consume 390W for both GPU.

Memory overclock give nothing for EWBF zec mining. Somebody tried to reduce memory clock to reduce heat or power consumption? I can reduce -201Mhz in Afterburner.

Thanks
