Scores go down on three way 580'S? What am I missing? LN-2?

Got to bring more power to the party :ohcrap:

You mean volt mode and subzero temps or..............if I use the three way bridge the board shows the middle card as X1?

Overclocked 3930 = 175 to 200 TDP

3x overclocked 580 = 900 TDP

hard drive fans and so fourth, willing to bet you are low on power

what PS are you using ? just piggy back another one on you have laying around and run the two fo the cards off of that and see if it helps

LOL I already was, I have the corsair AX1200 but can only run two cards as all the CPU power plugs take all my extra pony tails. So I jumper pinned my test PSU for the third 580. It still seems like it's starving, any other hints? I'm open fer blowing stuff up :clapping:

Well if you ask me it can only be three things here

1. Power supply dieing

2. Video card dieing

3. Both Dieing

:ohcrap:

something is dying i beat three 580's with two 4890 :ohcrap: What about when I'm in windows i hit the thing on my GPU-Z and it show the middle card at 1X?

Inching along :cool3:

o yea there is a problem if that is the case bro ?

working it bro , awesome :thumbsup:

OK, well assuming the best, when I add the bench test PSU is when I have issue's. This AX is not even two years old, I bought it shortly after joining here. You are right the 580's draw a TON of power, I may need to invest in a second GOOD PSU. SO any way, I'm bringin out the guns............

You can see in this photo the PSU plugs on the mainboard, there is a third plug near the I/O/sound for multi GPU'S. with that plugged in I can only power up two GPU'S with double 6 pin's each. Second photo is the gun's, I was to lazy to unwrap them. First up is my 6950's, just two.
