AGP Texture Acceleration Help

[BamaMike]

Hi All,

I ran the dxdiag.exe and noticed that the AGP acceleration was disabled. Shouldn't it be enabled? But the option is grayed out and I can't use it. I have an Asus P4G8X Deluxe motherboad with a VisionTek 9800 pro 256mb. Any help would be appreciated.

Mike

P.S. Thanks for all who recommended me buying this video card. It's awesome!!! (Hurt my wallet though)

Hi,

Here's my problem. For some reason I have two radeon 9800 pro video cards listed in my device manager. One says radeon 9800 pro....and the other says the same but has "secondary" on it too.
Both entries are listed as being located in a PCI Slot instead of AGP. I've tried removing the drivers and uninstalling both entries in device manager. Everytime my computer reboots, windows xp locates a radeon 9800 pro and an additional video controller which is the "secondary". I have my BIOS set at 8x and aperture size 256mb. Also in the ATI control panel, in the smartgart tab, it won't let me set it to 8X probably because its listed in a PCI slot in the device manager. And of course in dxdiag.exe....agp texture acceleration is disabled. Please excuse me for the long message, but i'm a newbie at all this and learning as I go. Any help would definetly be appreciated.
Thanks alot. Mike

dont worry it says pci bus 1 right? well thats what the motherboard names its agp slot on itself. Theres no problem there, ur graphics run fine right?

i forgot to mention that in your motherboard settings, somewhere should be the agp setting, switch it to AUTO, not 4x. Thats probably what its on.

My Radeon 9500pro is in the AGP slot, and Device manager shows "PCI bus 3, device 0, function1". As R_1_Oh_Seven already mentioned, it's the AGP slot, and all functions fine.

As far as the "Secondary" display device, that is expected. If I'm not mistaken, you have 2 'output' connectors on your vid card (one analog D-sub, one digital DVI). Your card supports two monitors.

Right-click your desktop -> Properties.
Click on the [settings] tab, and click [advanced...] button. Then, find the [Troubleshoot] tab, and ensure the slider is all the way to the right.

The settings that R_1_Oh_Seven mentions (agp setting AUTO/4x) are in your BIOS. If I'm not mistaken, you can hit [tab] when you see the ASUS logo when you boot, and then press [Delete] key (or whatever it mentions).

Good luck! Someone out there has a solution!

yes i forgot to tell him its called BIOS, plus again but all the crap wev said is worthless right now cuz you have it all set right. To get agp texture acceleration update (flash) your bios. Find ur motherboard dealers site, and download the drivers for ur chipsets and stuff. You then should have agp texture acceleration if your flashing process didnt permanently crash ur pc(yea it can happen)

Try this, download and install Intel's chipset INF driver, ATI's Catalyst drivers (version 3.7 or greater) and Microsoft's DirectX 9.

Once installed, verify again with dxdiag.exe. If it still lists no AGP acceleration, goto your BIOS setup menu at boot. Disable AGP fast writes, set the AGP aperature to 1/2 your memory (or greatest setting), and drop the transfer rate to 4x. Drop the transfer rate to 4x for ATI's SMARTGART control as well.

The Intel E7205 chipset features a few signal timing issues that don't meet the AGP 3.0 specifications. The tVALmin or data valid window are slightly skewed in early revision chipsets, thus meaning AGP 8x transfers are not recommended if you have an early revision motherboard. The latest Intel Chipset driver works to correct these issues, but it does not work in all cases, thus forcing a 4x AGP rate to be used.

As to any performance difference between 4x and 8x, it is not appreciable enough to even detect outside of synthetic bechnmark testing. Frame rates in most games may change by 1-2%, especially since you Radeon includes 256MB of onboard memory.

Hope this helps,
