Yeah I think you should go back to the old firmware.

Why did you upgrade anyway?
Was it broken?

Long story, but one has never clocked to 400 without 10% more errors than the other. They have the same cooling (lots), I've tested power supplies, switched control boards (I also got one replaced by sushi) and can't narrow it down... the only difference is the larger capacitors on the newer boards, which I noticed after breaking some off, so technically one is now broken, but is working exactly as it was before the repair. I figured the upgrade wouldn't hurt, but it hasn't helped at all.

My thoughts are that you should go back to the old firmware and also do a moderate overclock something like 375 and take it from there.

Yeah thanks for the input, tried all the steps, found the sweet spot: 196Gh/s @387.5mhz with 0.9%HW... not bad... I'll reload the old firmware... just waiting on an announced 7hr internet downtime :-(
