Too much stale shares Claymore etherum mining / GTX 1070 / ethermine.org

[N0pr3s3n7]

Hello I\m recently getting too much stale shares (arround 3-4 %)which results in me having LOWER avarage effective hash rate (my system has arround 325 mh/s and I got arround 300 mh/s avarage effective ) and I dont know how to troubleshoot this and find which cards creates them / whole system ? , and how to minimize them. Im running 10x MSI 1070 and 1x EVGA 1070 , all of them are running at  65 % TDP (Tried higher arround 70 % tdp but still got same amount of stale shares) , + 20 core , + 600 memory (tried also 570 / 550 / now they are running at 540 )  - 75 % fan , they all sit at under 60 degrees or max 65-66 in peak day hours when outside temp is 35 + . Is it normal to have so much stale shares ? Just to mention I got few rejected shares ( dont know if they count towards stale ) because I saw that claymore somehow lost connection to the pool , but overall shares rejected are arround 5 for 3000 shares , but every hou rIm getting more than 2 % stale shares. Any ideas guys ? Thanks in advance

When you have Claymore open press 'S' and it will show statistics.

It will show submitted shares per card. If there is a card that has significantly less shares submitted than the others, you know it's causing issues.

Also, if any cards are generating invalid shares, that will lower effective hashrates, too.

In both cases, slight underclock usually fixes the issue. I drop the memory by 10mhz, restart, and look at it again in 24 hours.

This is for AMD cards. Not sure if it would be different for nVidia cards.
