what am I missing here? pcie 2.0 x8 vs pcie 1.0 x8 slots

Travis Moore · Apr 2, 2016

I have obtained a Supermicro X7DB3 motherboard with everything on it, cpu, ram, hdd.
I want to use this for media in my home but the graphics capability is lacking.

The specs state that this board has three PCIE x8 slots, however when I purchased a PCIE x8 gpu it does not even come CLOSE to fitting. Which I figured it wouldn't based on the picture of the gpu...

My question to you is how does a pcie x8 card, not fit in a pcie x8 slot?
Is there any way I can modify it to work?

GPU
motherboard

Regardless of what that description says that is a X16 card. Never seen a X8 video card not saying they don't exist just never seen one.

PCIE is an architecture, it has nothing to do with size.

it'll fit in one of the three bottom slots won't it?

you do know how old that board is don't you?

I correct myself a X8 video card.

sorry those are the pci-x's. for pci-e you only have short slots. x8 and x4. your card should be twice as long as a x8.

it has a built in gpu, so you don't really need the card?

Those are PCI-X slots. https://en.wikipedia.org/wiki/PCI-X
PCI-X is often confused by name with similar-sounding PCI Express, commonly abbreviated as PCI-E or PCIe, although the cards themselves are totally incompatible and look different. While they are both high-speed computer buses for internal peripherals, they differ in many ways. The first is that PCI-X is a 64-bit parallel interface that is backward compatible with 32-bit PCI devices. PCIe is a serial point-to-point connection with a different physical interface that was designed to supersede both PCI and PCI-X.

When you say it wont fit, do you mean it wont fit in the slot or because of the design and/or the size of the card it wont fit?

Spotted that when I found a better picture

His video card is a PCI-E 16 card that was listed wrong as a X8 card.

The motherboard does have pci express 8x slots.

Zerk2012 · Apr 2, 2016

As old as that board is I'm not even sure the card I listed will work, but the MSI card he linked from Newegg is a X16 card not a X8 as listed.

Zerk2012 :

and it only has short x8 slots, so it'll not fit

Yep found a true X8 card but not sure a 7XX series will work with that old of a board.

It's got USB 2.0, USB GPU? or a pci-e usb3.1 card and USB GPU?

Travis Moore · Apr 2, 2016

Oh wow, you guys responded way faster than I expected.

I want to put a gpu in it because the video output is incredibly blurry. it scores at 1 on the windows 7 experience index.
I did find a card that fits in PCIE 1x slots, but they wanted a fortune for it.

I have never tried a USB gpu, how well do they tend to work?

Don't know, but the true 8x above should be ok

what am I missing here? pcie 2.0 x8 vs pcie 1.0 x8 slots
