PCI-E slot detected as an AGP slot

I only have PCI slots but shows that I have an AGP slot.
My motherboard has 2 slots
- PCI 32bit
- PCI-E 2.0 x16



This programs (speccy) shows that one of them is an AGP slot, replacing the PCIe x16 slot which is confusing

I'm starting to think that this is the cause why my GPU isn't found in Device Manager and not working. The fans are spinning, I also tried 3 different GPUs but nothing works.



Motherboard:
Manufacturer: Emaxx Technologies Inc
Model: EMX-MCP61D3-iCafe
Version: V2.0
OS: Windows 8.1 Pro 64-bit

Given the limited info available on the motherboard (their website no longer lists it), I can only speculate...

I would assume the board is ultimately manufactured by ECS and, given the relative age, may utilize their proprietary AGP express interface.

That being said though, AM2+ launched in late '07 IIRC.... so AGP support wasn't really necessary at that point, but I guess a nice marketing feature. If you needed AGP support, there's not many options. If you didn't, it didn't restrict the functionality of the PCIe slot.

From Wiki:

From Wiki:
Not a true AGP interface, but allows an AGP card to be connected over the legacy PCI bus on a PCI Express motherboard. It is a technology used on motherboards made by ECS, intended to allow an existing AGP card to be used in a new motherboard instead of requiring a PCIe card to be obtained (since the introduction of PCIe graphics cards few motherboards provide AGP slots). An "AGP Express" slot is basically a PCI slot (with twice the electrical power) with an AGP connector. It offers backward compatibility with AGP cards, but provides incomplete support[12] (some AGP cards do not work with AGP Express) and reduced performance—the card is forced to use the shared PCI bus at its lower bandwidth, rather than having exclusive use of the faster AGP.

It's still a PCIe slot.... just capable of accepting both.

That explains a lot. Thanks for the info

But can you still help me with this GPU problem, I keep resetting the bios and cmos, nothing works.
the GPU I use can't be detected or be listed on device manager. As I said, I tried using 3 different GPUs.

Without knowing too much about the board, it's hard to say.

I'd take a wild guess that the "default" configuration in the BIOS is for that particular slot to = AGP
You may have to manually configure it to be PCIe?

Have you tried each of the GPUs in both PCIe slots? I would assume if ^ that is the case, then one would "work" by default and the other wouldn't.

I'm currently using the On-Board Graphics Card, Not the GPU, because it can't be detected.

So GPU-Z would only detect the On-Board GPU.

I just went on my BIOS settings, I don't see any PCI settings or slot configuration.




It only have one PCIe x16 slot, the other one is PCI slot

True, but the problem was already answered by Barty1884
