I had 1 PSU powering the boards and the controller.  I put another psu on the controller and booted up the boards first, and now it is running at full speed.  Thanks for the advise you two..Smiley

This makes you wonder if it would be worth installing a cut-off switch on the power cable that connects to the controller.  This would be helpful if you are using a single large PSU...

Why would that matter? My guess is that the 1 PSU alone didn't have enough power?

Regarding adding multiple PSU's etc, I can recommend add2psu adapters. http://www.add2psu.com/
You could get these to power the hashing boards first, and controllers later.

I used them on my GPU rigs back in the day.

Edit:

DO NOT use these on multiple circuits!

Are you sure about that ATCkit? I guess you are if you're doing it! ^^

Its not really necessary. If you're using 2 PSU, you just flip its power switch in the back. If not there's those flip switch sure, but its added hardware that's ultimately superfluous.

You just power the PSU that is NOT connected to the controller first, then flip the one that is connected to the board last. It doesn't matter if its also connected to boards.

Its just that the boards don't actually power up and start running even though they are connected to a power line until the controller "wake" them up.
