What is this PCIe Slot?

[EposVox]

I got my motherboard for my new project in today. It has normal PCI, shorter PCIe, and a graphics card sized PCIe slot, but this top one...

what is it?

Mini PCIe?

Looks like an 8x and a 1x right next to each other, weird

That's what I had thought, but I couldn't imagine how that could be used, haha.

I am assuming this is a server motherboard?

Yeah, the  Supermicro Server X8DTi-F.

 

I guess I could read and it says:

• 1 (x16) PCI-E 2.0,
• 2 (x8) PCI-E 2.0,
• 1 (x4) PCI-E (in x8 slot),
• 2x PCI 33MHz slots

Just don't get why they're next to each other.

Certain industrial cards will use it, on older boards there was something similar such as PCI 64bit slots (PCI-X) and different voltage PCI slots. I believe this serves the same purpose for cards that need 2 different lanes.

Interesting.. thanks.

but those are pci-x and the slot he has are pci-e

Alright, those are primarily for custom add-in cards. Sheldon has a good example of something that relates more closely to this motherboard. Some other motherboards have split PCI-E slots and use something like this.

They would just be manufactured to look like his example.

Interesting.. thanks.

Np, also on SuperMicro's site it say this:   1 (x4) PCI-E (in x8 slot)

 

I assume it is for industrial cards like I said that need 2 different lanes to operate instead of just one full x16 slot.

but those are pci-x and the slot he has are pci-e

Yes but I am explaining that server/industrial systems have these type of expansion slots to accommodate proprietary cards and in some cases custom ones for certain work loads. PCI-X is just an easy example of how to explain it for me  

[iHardware Shelden]

It's for HP's KVM hardware in reality.

Ahh well there we go

Thanks guys. I'll just ignore it for the most part, then.

You could always use a riser card to turn it into a physical x16 slot to use a GPU or something else.
