Claymore, Hashrate and Overclocks

[nabil24]

Hello,

Just set up my rig and intalled windows 10 pro, installed AMD mining drivers for my 2 RX 580 Saphhire nitro + 4Go Elpida, overclocked it to 29.5mh/s. I'm using clayemore and nanopool for mining.

The problem is : After a while of mining, claymore crash and restart automatically but set down my hashrate to 26mh/s

Anyone faced this problem ?

Thank you !!
