Ok, so were 3 days 5 hrs in on the 243.75's and I've noticed some drops in hash. I know machines have variance of +/- 10% sometimes but it seems like a steady but slow decline. What's weird is the time passed being only 2 days and change, compared to say a month or something.
Anyone else get this with OC'd machines ?
First image is the 237.5 machine that seems to be "leaking" as well.

Total loss around 27 Gh/s, 26 if you subtract the +1 on machine two.
The S3 exhibits inconsistent and confusing hashing patterns; at least in my case anyway.
At 243.75M, my units could be around 478GH/s within the first hour and slowly improve to reach a little over 491GH/s in the next 4 hours or so. But then again, in a different session, they could also be already at 491GH/s within the first hour and slowly deteriorate to around 488GH/s after an extensive period of time (a day or so) but only to eventually creep back up to between 490-491GH/s and stay there for a while. My pool side averages are much higher (generally a tad over 500GH/s) but just as erratic.
I miss the consistency of the S1s. They were always at 179.xxGH/s from week to week (up to a couple of months) continuously.
