Hi Guys,

I am a new miner and am trying to figure out what is going on here.  With all of my 280x s, they average 15-20KHs slower when they don't have a monitor connected to at least one card on the motherboard.

As soon as I connect a monitor to anyone of the cards connected to the motherboard all the cards start hashing faster.

I am running 2 x 280x s per motherboard and using the Beta 9.5 AMD driver with CGMiner 3.5.1

Any ideas?

Thanks.
