Is this good performance for 1080ti?

Hello guys,

Im running 8 x 1080ti (7 x Palit Gamerock +1 x Gigabyte Aorus Xtreme) cards on ethos, mining zcash with DSTM miner. Just started mining few days ago, would like to check if Im getting best performance from my cards? I`m not after max hashrate, but good balance between performance and power consumption.

I tried lot of different settings, green ones are best, I`m using ones from column L.

Thanks
