Guys, i have two 1080 ti, im trying to use the perfetct --mt + overclock settings, to use less energy with maximum hashrate

Sometimes i mine the entire day without cuda crashes, and then, with the same settings it starts do crash each hour...

any tip to see which card is making cuda crash using logs?
maybe exists a log option to log only cuda crashes?

Im mining with nicehash, i can use Nicehash logs or NBMiner log,
