Mining hash dropped by half 6800

I started mining with a new 6800 a few weeks ago and it was running great ..I also have a 6800 xt and the 6800 was getting a better pool hashrate than my xt. They were both sitting at about 63 current.

This all changed yesterday when I noticed my average hashrate was down a good amount and was bouncing more than I've seen it before .. for some reason my 6800 was getting around 33 hashrate now. I tried raising the core clock from 1200 to 1250 like my xt. It seemed to go back up to around 61. I came back a couple hours later and it was down in the 40s again.

I just unplugged my system and checked all wires and re did all my overclocks. Running about 61 hash with my other gpus running at what they normally do.

I'm using the mining chambers oc settings at about 114 w.

Any help or advice would be greatly appreciated
