GeForce GTX 650 Ti Boost Runs in PCI-e 1.1 mode

Greetings,

I have a newly bought computer with the following specifications:
Motherboard: Asus P8H77-V LE
CPU: Intel Core i5-3470, 3500 MHz
VGA: nVIDIA GeForce GTX 650 Ti Boost (MSI)

My problem is the following:

As you can see, my card runs in 1.1 mode according to GPU-Z and neither GPU-Z nor Aida can determine the memory size, gpu clock rate, etc. I've tried various Nvidia drivers but none of them helped me out with this issue.

In Aida it says the VGA is using a PCI-E 2.0 x16 port, but it's installed in the PCI 3.0 port on the motherboard.

Could it be a problem with the hardware? Motherboard/VGA issue? I don't have another computer to test it with, I hope you guys can help me out!

Thanks in advance!

the gpu automatically idles itself to pcie 1.1x16 when not in use. Try to run a windowed 3d application(any game, windows experience index test, or even benchmark like furmark/3dmark) but make sure you run them in windowed mode and while your running the application, take a look at gpuz window. It should be showing pcie 3.0x16

Your gpuz version is up to date but I think a newer version should be able to detect the memory when it comes out.
try downloading the beta drivers from here http://www.geforce.com/drivers/beta-legacy

I've tried that already, but the VGA stayed in 1.1x16 mode and the rendering was extremely laggy and slow. I wanted to test the VGA with Furmark too, but I've received the following output:
Detected graphics hardware:
- OpenGL renderer (main graphics card): Microsoft Basic Display Driver
- OpenGL version detected: 1.1
- Full device ID: ROOT\BasicDisplay

oh I see, I am leaning towards the hardwares being faulty. But still as a last resort try the beta drivers from the previous link. And the bios and chipset drivers from here http://www.asus.com/Motherboards/P8H77V_LE/#support_Dow...

Otherwise, I would have to say either the moetherboard or the vga is faulty.

Also try putting that vga into the PCIe 2.0 x16 (x4 mode) black slot just to see if it makes a difference. That would mean your PCIe 3.0 blue slot is damaged/faulty

See the blue question mark next to it? Click it and do the render test to see the full speed.

Okay, we've plugged it in the black slot and GPU-Z changed the Bus Interface to PCI-E 2.0 x16 @ x4 1.1, so it still runs in 1.1 mode. I've installed the Nvidia Beta driver too that you've mentioned, but even the Nvidia Control Panel displays an error message saying that: "You are not currently using a display attached to an NVIDIA GPU.".

I'm downloading the Chipset drivers, but it seems the VGA might be faulty. I'll respond as soon as it's done.

Edit: As soon as I wanted to install the Chipset drivers, the setup told me that I have the latest version installed. I'll contact the shop then, thank you for your help shamsmu!

"You are not currently using a display attached to an NVIDIA GPU.".

This alone proves the gpu is faulty, seen that message too many times. Had to RMA every time I saw that message.

Hi folks,

I don't have any solutions, but I have questions of you can help, please.

I have been looking for some time at the very same Gigabyte GTX 650 Ti Boost. My current motherboard is quite old with a PCI-E 1.1 slot. Can you say for sure this Gigabyte will work for me?

I have searched lots and found that PCI-E 3.0 should be compatible back to PCI-E 1.1, but not PCI-E 1.0.
Also the Zotac website GTX 650 Ti Boost is specced 3.0 (compatible with 1.1 - specifically).
I have my eye on the Gigabyte though.

Also I read the GTX 650 works on a PCI-E 1.1, and doesn't bottleneck on bandwidth. I'm hoping fully the Ti Boost will be OK.

Well I went ahead and bought a Gigabyte GTX 650 Ti Boost. My GPU-Z reads the same as Bhawk1990: it says PCI-E 1.1x16@x16 1.1

Nvidia Control Panel sees my GPU.

Oddly I wonder too it should say PCI-E 3.0 x16@x16 1.1, as Bhak1990 thought. I suggest that because when I installed the card, Windows did its thing and started looking for drivers. During that time, the screen resolution was low, and fuzzy. Anyway I opened GPU-Z at that point, and it did say PCI-E 3.0 x16@x16 1.1.

Now with correct driver installed, I see PCI-E 1.1x16@x16 1.1
I get the same laggy performance, and a weak 3D Mark '06 score.

I did lots of reading before buying a card, because I feared problems. The following page assured me I should be OK. http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI...

It says specifically, quote, "Everything down to x16 1.1 and its equivalents (x8 2.0, x4 3.0) provides sufficient gaming performance even with the latest graphics hardware, losing only 5% average in worst-case."

As I have 1.1x16 I expected a good result. Any ideas anyone please?


@Bhawk1990, also, when you moved the card to the other slot, you said you see x4 1.1
That would slow stuff down lots. Anything below x16 1.1 impact lots on new cards. (See the link I added here for info on that.)
