motherboard/vid card issues

[jon1117]

Specs:

P4 2.4 GHZ
Asus P4P800 motherboard
Abit Siluro GF4 Ti4200 8xAGP video
512MB PC2700 ram

After putting this system together I installed a few of my regualr games and was shocked at the lousy FPS i was getting. For the heck of it i installed Sisoft Sandra2003 and did a performance test on it and a few worrisome things came up like that my AGP bus wasn't enabled and that the frequency was too low. So I started digging around.

1. My Nvidia driver states that the bus that the card is installed on is AGP(PCI mode).

2. Device manager states that its installed on PCI bus 1.

3. When i view devices by connection it shows that the vid card is installed on PCI Standard PCI-to-PCI bridge, and that its sharing IRQ 16 with a USB host controller.

Nowhere in my BIOs does it have a setting to switch from AGP 4x to 8x, as a matter of fact nowhere in the BIOS does it say anything about AGP except for boot options for AGP/PCI. I haven't seen this before every other PC has always stated AGP in drivers and installed on Standard AGP-to-PCI bridge. Does anyone know if these 3 things sound correct or if it sounds like i have a problem with my chipset? thanks in advance

Does your board maybe have an onboard video card. If so then disable it in the BIOS. If not then look if there is a BIOS upgrade available or try to get an other board.

Well, as for the PCI mode thing, that is because you probably need to install the chipset specific AGP driver.

As for the AGP thing, AGP 4X is fine because there isn't anything commercially available that I am aware of that actually will utilize AGP 8X. However, if you wanted to enable AGP 8X I would suggest you try upping your apeture size to 256MB (as apeture size is directly proportional to the AGP Mode that's used).

I would also go to the display properties and turn off anti-aliasing because of it's negative impact on framerate.

Make sure your directx and video/sound drivers are current.

Cheers!

Ok...and now i'm going to play dumb. Where so I get the Chipset specfic agp driver from? Its not on the motherbaord CD and I can't find it anywhere on Asus site download for the motherboard
