AMD HD 7970 hash stops after 10min

[gg234]

Hi,

I have two new MSI AMD HD 7970 cards and using multiminer to do dogecoin.One card seems to work properly and the other card stops hash after 10min to make it work i have to stop and start multiminer.

Can you let me know what could be causing this and i have also tried changing card fan speed,temp control settings but no use.

Thanks for your help

What are the temps of your cards? Are they inside your computer or in an open air rig? If you haven't done so already take the side panel off and point a fan into your case full blast. See if that helps.
