I have had a Terraminer IV hashing well for quite a few months. All of a sudden the speeds are sub-par. I am getting 550Gh/s on CTA1 and 225Gh/s on CTA2.
I have seen some old threads that mention the original thermal compound drying out and core's overheating therefore running slower. If that was my problem would I see higher High temps on the cores? If I reboot the speeds seem to be higher initially, then reduce down over time.
I have posted a screen cap of my status, Dropbox link
