AGP Slot

[cutlass]

I just purchased a MSI KT4V-L..and an Abit KD7....both are brand new....it's been about 2 years since I bought a new motherboard....is there some reason that the AGP slot on both of these boards seem to be backwards with the smaller slot to the rear of the board..would appreciate come help before I start on the vendor..thanks...

That's the Audio Modem Riser slot (AMR) I believe...the AGP is still the first slot on the board down from the CPU.

it's not the amr...this is the agp slot ..first in line after the cpu....

They could possibly be made for the newer AGP Pro, so they would look different than your older AGP slots.

The KD7-RAID has an 8x AGP Pro video card slot, and my Radeon 9200 Pro works very nice in it

that explains it..I checked the new one I built for the wife a few months ago...bought it barebones with card already installed..problem solved..thanks everyone...

It's not backwards, it's keyed.

What you got there is an old board whose AGP slot was 3.3V-signalling-only, indicated by the 1.5V-signalling compatibility key position blocked by the plastic tab you see. And you got a new board that supports 1.5V signalling but not 3.3V, and thus has the other key position tabbed.
Universal AGP slots have no tabs at all.

Cards must match that by having a notch in their connector edge for each of the two signalling voltage modes they support.

So if your stuff cannot be plugged together, it's not compatible.

3.3V signalling is for AGP 1x and 2x modes.
1.5V signalling is for 4x modes; 8x mode is thrown in here too although it uses .8V signalling.
