Question about my AGP8X.

[tedthebear]

I have an nVidia nForce2-IGP chip set on an Asus A7N8X-LA mobo. I had a computer shop install an Asus AGP-V9180 graphics card with 64 mb memory.
My nVidia System Utility says my AGP bus is running at 66 mhz. Since my new graphics card uses the NVIDIA GeForce4 MX 440 with AGP8X how come the AGP bus is only running at 66 mhz?

AIDA32 says my AGP slot is empty but one of my PCI slots is full. Could the computer shop have stuck my Asus graphics card in a PCI slot by mistake or is that where it is supposed to be?

Why did I buy an AGP graphics card if they don't insert it in the AGP slot? My monitor plugs into the back of the graphics card through an opening in the case. Is it possible my AGP slot didn't offer an opening for the monitor plug and that's why my shop used the PCI slot instead?

Help!

P.S. I am wondering if all AGP buses run at a maximum of 66 mhz and the 8X refers to the speed of the GPU.

Yes, the AGP bus runs at 66MHZ.

Run DXDIAG and see if AGP texture acceleration is enabled. If it's not, you need to reinstall your motherboard chipset drivers.

I don't think it's possible to put the cards in the wrong slots, btw. Perhaps they gave you a PCI card?

The AGP slot is brown and set back further than the white PCI slots. It will be the topmost slot, or the rightmost slot if you have a desktop PC.

8X refers to the data transfer rate of the AGP port, and it is not any faster than 4X in reality.

It's normal, 3DMark03 does the same when listing a AGP card as a PCI and 66 MHz is also normal. If you really want to find out you could always open up your case and see if the gfx card is occupying the top expansion slot assuming the system is enclosed and correctly installed into a tower type ATX case.

Yes all AGP buses run at 66MHz. 8x just means that it theoretically has eight times the bandwidth of the original AGP (1x). As stated above, just pop open the case and see what slot the video card is in, if it's a short, brown, slightly offset slot you're fine. Here's a picture of which slot is the AGP slot on what should be a motherboard similar to yours:a7n8x-vm_l.jpg

You don't have to open the case to tell if you have a card in the AGP slot as it is always the last slot right next to the I/O ports. So you just have to look at the back and see if the video card is in the very last slot next to the I/O port panel. If yes, then AGP; if no, then PCI.

You cannot install an agp card in a pci slot. it simply won't fit. if you picked out and bought the agp card yourself
for the shop to install the chances of them installing a pci version instead of yours is not likely.
As mentioned above just look at the back of the computer and make sure your card is in the very top slot
which normally the agp slot. some cases, like my two have one cover above the agp that's not
used for anything so you might see your card in the second slot from the top instead of the first.

Thank you everyone. Yes, it does look like the aida32 DMI was wrong. They did put it in the top AGP slot and there are three PCI slots below it; two empty, and one with the dial-up modem installed. I knew I would get to the bottom of it thanks to u guys.

Also AGP is listed on M/B's as PCI slot 0 not AGP slot.
