I've discovered that when I have 3 7970's on the same motherboard they run slower do you know why this is?

I'm thinking about putting five 5870's on an asrock extreme 6 board

My question is will using an x1 to x16 riser cable impact the kh/s i'm getting per card? or just the card that is on the riser.
Also should I get a powered? Also can anyone tell me a good cheap board that can handle five cards or is mine it?

I haven't gotten a stale yet.  been mining for the last couple of hours.  Good luck

I don't want to get into the China - USA debate; but I just hope people are aware of the pitfalls of an exchange with low volumes.

Seems to me since the hacker couldn't withdraw; he used the gap in the buy/sell orders to get money from me. Luckily I saw in time and saved 60% of my FTCs. Hopefully will make up the WDCs in the lotto.

What I dont understand is why  BTG is not on traded on cryptsy yet...I mean with such an active dev and interesting concept.

can this be right i'm showing no network hash
