EVGA GTX 680 SC+ SLI, not posting

Frozenn · Dec 24, 2012, 04:01 PM

I just recieved my second gtx 680 today and once i installed it, the screen goes black right before it boots into windows and then restarts. ive tried both video cards by themselves and it works great. but it doesnt post once they are both installed. im not sure whatelse to do, ive checked all the settings in my BIOS and i cannot get it to post with both cards installed

Sounds like a power supply problem to me.

Did you try one card in the second slot to see if it's faulty?

Frozenn · Dec 24, 2012, 04:11 PM

yes i did i tested the new card alone in both slots in my motherboard and ran games on both to make sure the card was working properly, and both of the 680s are clocked the same.

the other gtx 680 ive had for about 2 months now with no problems.

Need more info on the hardware, fill the UserCP/System specs

My guess, PSU you need more power/amp´s 12V Rail

Frozenn · Dec 24, 2012, 04:29 PM

my corsair TX850 V2 can put out 70A on a single +12v rail

Frozenn · Dec 24, 2012, 06:46 PM

ok I updated it

MxPhenom 216 · Dec 24, 2012, 07:01 PM

Theres something else going on thats plenty of amps for 680 sli.

Asylum · Dec 24, 2012, 07:13 PM

Try another sli bridge.

Frozenn · Dec 24, 2012, 07:24 PM

it should still boot into windows if i dont use an SLI bridge. for example i could just set it as a dedicated phys X card. right??

i dont have another SLI bridge i only got 1 with my motherboard the 3 video cards i bought
asus 6950, evga 680 sc+ x2. didnt come with sli bridges

Rei86 · Dec 24, 2012, 07:30 PM

Turn it on with both GPUs installed and power connected. Than go ahead and turn it on WITHOUT them connected with the SLi Bridge.

Frozenn · Dec 25, 2012, 04:35 AM

ok ive tried doing that and im getting the same result. on boxing day ill be trying out a new motherboard and powersupply once my friend comes over. it just keeps restarting before it goes into windows, im not sure what is causing the problem, unless something is broken? but the motherboard slots work fine alone just together they dont work and with the power supply i cant really say, it works with 1 card and doesnt with 2 but the motherboard is also a factor for possible failure. so im not sure how to proceed?

AthlonX2 · Dec 25, 2012, 04:45 AM

Maybe its an issue with the PCIe slots going to x8 + x8? Do 680s require x16 to work correctly?

Frozenn · Dec 25, 2012, 02:54 PM

no it does not you can a 680 in 4x mode aswell if you are doing 3 or 4 way sli for example.

nope, mine are running x8 x8.

If it works with one connected to power and won't with two connected to power, the only thing that comes down too is the PSU.

Frozenn · Dec 25, 2012, 07:05 PM

I agree thats also what i think the problem is, i will be using a friends corsair ax750w instead of my tx850w it's possible that my PSU is faulty ill contact corsair about a RMA.
