GeForce GT 730 PCI Express x16 not supported?

[kowal15]

Hi!

I bought a brand new mainboard ASRock FM2A68M-DG3+ and graphic card Zotac GeForce GT 730. Is it not support PCI Express x16? When render test in GPU-Z is running in the bus interface I can see PCIe x8 2.0 @ x8 2.0. Is it everything ok? I think it should be PCIe x16 2.0. Screenshot link from GPU-Z and CPU-Z: https://screenshot.net/ll9d3fo

Thanks for reply.

Most MB's downclock the lanes until it's needed, so under idle GPU-Z always shows a lower usage. Trying running the built in benchmark and see if it goes up.

Regardless, a 730 isn't even close to fully using anything near 16x anything.

No,the PCIE is fine cpu-z seems to show you half of the pcie,if you go to the ram tab you will see that its cuts your ram frequency to half too

Where can I run the build benchmark? In GPU-Z it is only x8 2.0 @ x8 2.0.

There is a small question mark - after Bus Interface info field in GPU-Z.
Press it and you'll have option to start a render test.

No information about x16.

I don't know about the 730, but I have a GT710 and although it is installed into a pcie x16 slot on the motherboard, the connection on the card is only 1/2 the length of the slot on the motherboard, and it also says PCIe x8 2.0 @ x8 2.0.

Is the connection on your GT 730 (the gold contacts) full length or half length like mine is?

It is full length

The info GPU-Z showing appears to be normal. Here are some more screenshots:

I see your card, and yes, it is full length:

Perhaps GPU-Z is reporting it incorrectly?

In NVIDIA settings looks the same: https://screenshot.net/0gp4kt0

What does Nvidia Control Panel show (system information button is on the lower left corner of the main screen)? Mine shows correctly there.

Maybe the mainboard has a limit? I found this in instruction: https://screenshot.net/r3oegc7

 

[mjslakeridge]

I think it is a limitation of your motherboard. I just looked at the Mainboard Tab in your CPU-Z screenshot. Says Max supported x8.

What motherboard did you have before? Did you just install a new MB and not reinstall Windows? Could be an after effect from not reinstalling, and/or not installing the chipset drivers.

That all said, as I said before, it doesn't matter, that card can't even come near to saturating 8x, nevermind 16x.

Sigh, all Kepler GT730 are PCIe x8 electrically. Zotac even makes one in x1 which should tell you how unimportant this is at the low end of the performance spectrum.

People get confused about this because the card appears to have the full complement of pads on the x16 connector, even if half of them aren't hooked up.

Before I had Gigabyte GA-945GCM-S2L, but i bought new few days ago. I did a clean install of OS.
