Seems to be working now, hashing on one blade at 1.4TH which seems a bit low to me.

I would agree with you normally, but these machines dont normally just drop like that without a reason, and in my experience a faulty PSU is far and away the most common problem. Im not guaranteeing thats it, but there is the first thing I would check if I was you.
OK, I'll check it out. Should be OK since it was running 2 BFL Monarchs before this. Maybe one of the cables are loose.

As I mentioned the red on the miner itself is normal when it is not at full strength. I am not sure why you would get a reboot cycle like that. It sounds like your PSU might not be up to snuff, even for a single board.
Its a corsair 750 watt PSU and the power config is at -1 so I would have thought that it should run alright.

Just power the board you want to hash with and leave the other disconnected. You do not need to disconnect anything internally, just dont power up one of the boards.
I am currently powering only the right board (when looking at the back). It seems to be powering up and down and sometimes connecting, hashing to a few TH and then going back down again.
The miner led is red, while the connector is blue or sometimes green.
It seems to power up and down, with everything randomly cycling through the colours which is very strange.
Any suggestions?

No you cannot adjust the speed like that. The miner is made to run within its spec.
Is it possible to run it with only one board active?
Yes, each board can power the controller on its own. The machine will show a red status light with one board missing but it will hash just fine and not damage the unit in any way.
Would i need to run this with only one board powered with just 3 6pin, or does the other one need to be completely disconnected to work correctly?

Does anyone know how to or tried to run the Avalon 741 under-clocked at around 700w?
I've attempted to lower the frequency in the cgminer config however it seems to have no effect.
Cheers
