P8P767 Second PCI-E Slot Running Slow than Primary?

post #1 of 10
Thread Starter 
So I own an Nvidia GTX 295. It's an old card, but a fast one, and I love it. The card itself works fine, and is fully powered. Unfortunately I have been having some issues with it not working properly on the primary slot recently. Turning on my PC gave me a black screen~ PC was working fine, but I could not get the screen to show. I thought my video card was dead~ but as a test I decided to put it on the second PCI-E 16x slot, and it works fine as long as it's on that slot.

On the primary slot (top slot) I get a vga-led error on the motherboard. I'm not sure if this is an indication of a motherboard failure or a video card failure, but the card works fine on the second slot.

Problem is, games are running WAY slower on the second slot than they ever did on the first. I get dramatic FPS drops in modern games now with it in the second slot. Which makes no sense to me as the P8P67 Evo is supposed to be PCI-E 16x on both slots. To be clear, I now have the GTX 295 (An sli video card, dual pcb) on the white slot of the motherboard.

Can anyone tell me why I would be suffering lower fps on games? Is my video card damaged? Is there a setting I can work with to get this slot to work as good as the primary slot? What gives?

(Asus P8P67 Evo. I can not edit the title, sorry.)

Isn't the second x16 slot only wired at x8? It shouldn't be a huge difference but that might explain part of it.

WHen I was running SLI, if I ran a card at x16 and x8, it was noticeable, try running in a x16 slot

The P8P67 Evo to my understanding has two x16 slots. I have it in the second. So~ I should have it already in a x16 slot...



It's currently sitting in the white slot.

Stats according to specifications~

Expansion Slots 2 x PCIe 2.0 x16 (x16 or dual x8) *1
1 x PCIe 2.0 x16 (x4 mode, black) *1
2 x PCIe 2.0 x1
2 x PCI


I currently can not run the video card on the primary top blue x16 slot. The black one will just run at x1...

That second slot is only x16 physically. It's not connected as such. From the manual:

The "PCIE 2.0 x16_2 Single VGA N/A" doesn't look too promising either.

So what could be causing my video card not to work on the primary slot? I've tested another video card and it works fine on the primary slot, but this one won't. I get a black screen on boot, and on the motherboard a tiny red led pops up that reads "VGA_LED" on it~ but only with the 295.

Putting a GTX 260 in it works just fine though, as well as a 9800 GT. For whatever reason, even after a year of flawless use, it won't accept the 295. frown.gif

That I don't know. Since the card works in the other slot I'd think there's a problem with the top slot, but since other cards work fine in it, you've got yourself a bit of a mystery I'm afraid.

I've never heard of this problem before, thus I can't find an answer on Google. It does seem like the slot is as fault, but since it accepts "older" cards, I don't really know what gives. The slot may not be able to handle the power requirements for it anymore? I don't know, it makes no sense to me. I unfortunately don't know anyone with a rig with a power supply capable of powering the 295, so I can't test the card on a separate motherboard to see if it's a fault with running the card at its maximum.

It's a very unique issue~ but it seems motherboard related so I posted it here... perhaps the nvidia board may know more?

So nobody in all of OCN/Intel Motherboards has ever run into this? :< I have a crippled system and it's going to elude the most techsavvy people I know. I would love to understand why this is happening.

For one, I keep hearing x8 shouldn't hurt performance of my 295 too much in the second slot. Yet Guild Wars 2 has gone from like 100+ frames to nothing more than 8-10. That's pretty severe~ Why would a video card work on the second slot, but not the primary one... when the primary one works with other cards?

I'm going to send this to Asus, as I believe it's under a 3-year warranty but I need something to tell them, and the peace of mind of knowing this won't happen with the replacement and being away from a computer for weeks. -.-

Have you tried pulling the CMOS battery out and running all settings at stock? I had a problem with a ASUS board and that's what customer service made me do before they would issue an RMA. Not really sure if it helps. Have you tried the card on another MB?


If you have tried other slots on the board and the only slot that doesn't is work is that one than it's time for RMA.
