What Sajin said is correct.
 
I've read all of this thread and I'm only getting that you've;
1.  RMAed the GPU three times
2.  You ran a bunch of test over and over again that doesn't really test the PCIe slot
 
So from that we can conclude that your motherboard is faulty and you're not willing to replace it because i'm guessing you don't have a backup/fallback machine to use when the part is out... 
 
I mean seriously if you don't want to replace your motherboard with a RMA or a another brand we can't help you.  You've already changed out your GPU THREE TIMES and every time it reported the slot you're running in is showing up as a GEN2 slot which we can pretty much again conclude that the MOBO is messed up.
 
 

I forced the motherboard BIOS to Gen3. GPU-Z confirms it is Gen 3 ("PCI-E 3.0x16@x16") as it did for Auto. NVCP still says it is "PCI Express x16 Gen2".

Why does NVCP disagree with GPU-Z? Nobody has answered this.

I've had to edit or delete several posts in this thread. Please respect each others opinions and post professional. It would be a shame if we have to lock down this thread.

 
Lol. You deleted my posts JUST as I edited them out for immature content lol.

You are jumping the gun deciding the mobo is at fault. I have had TWO video cards sofar both with very close serial numbers and the "replacement card" was obviously refurbished so I don't trust it. I bought my card new not long ago btw.

 
And you're jumping the gun in thinking its the GPUs fault.
 
In CPUZ is probably reading where the MOBO meets the GPU and nVidia is probably looking at where the GPU meets the MOBO.
 
1st off the peformance difference between GEN2 and GEN3 are negligible

But since you are worrying about it the only thing you can do now is to RMA the MOBO for another one and or purchase another model/brand.

If your 3rd card has the same issue I would try another motherboard. 

I assume you're talking to someone else. I haven't been "flashing the MB and vid card".
Nor have I had 3 cards. Yet. We'll see what happens.

Schayden,

I looked at your account and it appears there was a special testing request set before it shipped. I personally tested your card to make sure it was 100% functional before it left our facility. It appears to be out for delivery today. If you continue to have any issues with the replacement please let us know.

Thank you! An intelligent, helpful answer at last. Here's hoping this one works.

your partly correct ,since you highjacked someones  thread you did not notice,thats why this forum has a TOS about highjacking threads Granted you share a issue (and the flashing comment was directed towards the OP,you would have known that if you read it instead of highjacking the thread lol _but you completely took over his thread and turned it into your own lol .The points on the Mobo stand .Ask Asus to make a tool that tells you what you want as the mobo is the issue.Gpu sends the info to put it simply

You never reported the display driver was crashing.
 
Dude you can bang your head against the GPU wall all you want but after switching out your video card that much the only other route you have left is the MOBO.
 
But so far its like beating on a dead horse since you don't even want to consider it.

Read what I said:
"I have run memtest86+ for 19 hours, no errors. 

I have run Prime95 for 2 hours on the blend torture test, no errors. 

I have run 3DMark 11 and had the display driver crash. 

I have run OC Scanner Tessy and had the display driver crash. 

I have had over 50 display driver has stopped responding and recovered errors, and maybe a dozen outright lockups where I have to reboot the system. 

My power is stable, my system memory and CPU work. 

My motherboard BIOS is set to Gen3, GPU-Z is set to Gen3, but NVCP shows Gen2. 

I am on my second RMA with no solution in sight, and no real help troubleshooting this."

what much? twice?

 
You appear not to understand the issue
The problem is not the videocard or the drivers as they are 100% PCIe gen 3 compliant
 
The problem is related to the motherboard
You are thinking that because the BIOS says Gen3 it -must- be working fine.
This is not the case with many motherboards, as they were designed before Gen3 cards were available.
After Gen3 cards were released, it became clear that many "so called Gen3" motherboards could not operate correctly with a Gen3 card. This is a widespread issue and well known.
 
You must replace the motherboard
 
If you fail to do so, you cannot continue to blame the card and RMA because that is NOT the problem.

Provide a link please where this is discussed.

I have a P8Z77-V PRO Thunderbolt

 
 
What CPU do you have installed

schayden

Intel i7-3770K (ivy bridge)

 
That CPU supports Gen 3 PCIE  -known to work perfectly under the spec
Your videocard is a Gen 3 card  -known to work perfectly under the spec
 
That leaves only a config or motherboard issue
 
I suggest you start you own thread with a -exact- and complete listing of your hardware config
for review, to rule out any possible config issues.
 
There are many possible config issues that can relate to the increased bandwidth when using Gen3 PCIE
They should be tested and ruled out.
 
If the config is found to be free of issues, then that leaves only the motherboard.
 
Proper testing of Gen 3 issues is critical, as the the spec will revert if not properly stressed
There are also known user errors possible with driver installs
Along with the known problems of many programs used to detect PCIe Gen 3 spec 

He is a she. I have used Driver Fusion in Safe Mode. I told you earlier I would reinstall Windows as a last resort if this 3rd video card fails also.

lets keep going with RMA's till either we hit 100 RMA's on the same card or 1,000,000 people tell you its the Mobo ....

@Schayden

"According to NVCP System Information it looks like this driver forces you to run in PCI Express x16 Gen2 even if you have a Ivy Bridge CPU and a single GPU. Going back to driver 306.23 corrects this issue. So if you are running a SLI setup it would read PCI Express x8 Gen2 which isn't good at all.

It sounds like it might actually be the most current video drive if I'm not mistaken. Honestly though... The motherboard can cause crashing if the PCI-E lane is bad, it will definitely effect the way the videocard acts. I had an Asus Maximus Exreme IV and it was a disaster. Caused blue screens everywhere, and Asus Tech Support was absolutely horrible. I moved to evga because of them, and never gone back :) Truly though, I am sooooooooooo sorry that you're having these issues. I understand not wanting to spend more money, and believe me, :P I know the pain of troubleshooting a veeerry expensive computer... I hope for the best for you, but please don't rule out that it may be the mother board :P It could totally be possible, it really could. Even the professionals are suggesting it.

JUST IMAGINE if it was, and you got the new one, AND IT WORKED :D I'm sure you'd be totally happy.
