GTX680 not working with my new MOBO

Well try to do a bios reset even update and check if it works.

I have not changed anything in the bios, so how would I update the bios?

I don't think its likely, but could it be my psu? I have an 850 watt, gtx 680, x79 with 3930k, a corsair h100i, a hdd, an ssd, and 7 fans.

Well that psu seems good with W but what model ?

Also what mobo ? You can look the bios update in the mobo website

whats the brand of your PSU?

I put the mobo on the top, and its a TX850M from corsair.

Well the psu is good,

And here is the bios

I doubt this would have anything to do with it. But 2011 doesn't support PCI Express 3.0. Only your 3770K or any other Ivy Bridge Processor will support 3.0. Now you can try the card in a different slot and just give it a second it might work.. Because I know someone with a PE 670 on a R4E and 3930K so you shouldn't have this issue

My mobo is PCIe 3.0, or atleast thats what it says on the box, not to mention the gtx680 is backwards compatible with the PCIe 2.0, so I don't think thats the problem, but I will change ports and try it out.

Why would the BiOS work with the other card, and not the 680 though? the 680 is a newer graphics card by far..

What other card ? Did u try any card on that mobo ?

Changing to a dif pcie port didn't work.

Not sure, but it came with my comp I got in 2001, and it runs off of the pci slot at the bottom of my board. The Gtx680 worked on my z77 mobo, but have not tried anything else.

Well u can try a card and see if it works. Maybe the slots are faulty ?

Try the other card and tell us

Nice find rockdpm

I searched deeper and found people in the forum using the 3.0 hack and working perfectly

Found 3 with sli 680

Well to be honest. Its kinda like Cool bits..you know the program that allows you SLI a 2gb card with a 4Gb card... But it has prooved to be....unstable so its not used much. I don't recommend doing BIOS hacks but if you do. do it at your own risk. as once you do... your on your on. The company won't fix it (Unless you can get the BIOS back to the original flash)

Well there is the key to get it back if it fails   Always at your risk

I forgot that my card is the 4GB edition, could that affect anything? Also, on the x79 should I change to AMD since their cards are ready for PCIe 3.0 on the x79 platform?

Dude, It wouldn't matter which card you have. AMD or NVIDIA. they are both PCI-express 3.0 ready... What I was saying is you have to have a "IVY Bridge PROCESSOR" to even be able to utilize 3.0.. You don't have Ivy Bridge. you have the Sandy Bridge-E which is a better choice IMO since 3930K is a beast chip. I think it is either your PCI-e lane on your motherboard having a shady issue with 3.0 cards or your card is bad.. most likely its your 680

From what I understand is that its the drivers for NVIDIA that is preventing the use of PCIe, and I knew the gtx690 MUST have pcie, and the 680 had 4 GB of ram, which is unusual. The concern I have is that the 680 worked on the Z77 platform, and of a sudden it doesn't work for the x79 platform.

Right but your still not listening.. IVY Bridge Processor's are the only thing that will enable you to use PCI EXPRESS 3.0... Not the drivers from NVIDIA... I mean I'm sure you can do some sort of unstable back end dark side of the web hack that will enable 3.0 for the X79 platform to do it. But all those things are done at the users risk as there is no guarantee it will work.

Ivy Bride=1155 Z77
Sandy Bridge E=2011 X79
