Dear EWBF,

I use EWBF's Cuda Equihash Miner 0.5 mining algo 144_5 with my two 1080ti cards,but why tow cards have different hashrate GPU0: 65 Sol/s GPU1: 37 Sol/s,what wrong and how should i to solve

First of all check risers and TDP/core settings.

Correct, but before doing the first thing, ensure you have a powerful enough PSU (those 1080ti are quite electricity hungry).
Then swap cards' positions to eliminate bad riser/PCI port.
