GART isnt' support on PCI from what I understand (PCI-e it is)

For TESTING purposes, I would try another motherboard to see if a different result is gathered.

I am not sure I understand what you wrote.
I used the ali agp driver 1.60 and 1.66, I was thinking it was the gart, if it is not, well my bad.

I have not another ali motherboard, was searching for a P5A but I am not able to find one.
I think the Gigabyte is ok anyway.

My settings are:

Thank you Elianda, I assume you use drivers 1.90?

Hope it will be enough, but I am afraid it will not cause the fallback is done by the forceware drivers, not the ail driver.
As soon as install them and windows98 opens, a dialog box pops up telling me that the card has problem with AGP and that it will be set in pci mode.

try searching for the ali agp driver 1.72, works best for me.

Have you tried using RivaTuner? I remember it had some compatibility options I had to use in my Duron way back.

Look up Ali AGP Utility 1.40 for an easy way to see the Aladdin AGP parameters.

I'm not sure how stable any geforce or radeon can be on this chipset though.

As I feared, the fallback is done directly by the forceware drivers.
I can force turbo mode of the AGP utility, or even set it manually, it won't change anything, in nVidia control panel the AGP is set to pci, I can see that with coolbits.

Drivers are 52.16

I think I need to modify the registry of the forceware somehow to prevent them to do it.
Don't know how.

Have you installed the chipset drivers before?

Rivatuner can change the NV AGP settings but you are likely to have problems....

I will try Rivatuner.
I didn't have this problem on winXP or 2000, so I don't think it is strictly related to the hardware.

Thank you.

Hi all,
little update.

I installed 56.64 drivers after ali drivers 1.82, it appears that this procedures succesfully enabled AGP acceleration.

BUT

performace wise, the system is really slow (2800 3dMark2001 points)

I reverted to 52.16 but AGAIN, even forcing the registry, I am in PCI mode.
I launched 3Dmark2001SE anyway and I obtained those results:

VGA is at 390Mhz core, 700Mhz mem.
As you can see, the VGA is in PCI mode, can't do nothing about that.
If I can enable AGP I'm sure I can squeeze more....

What do you think?

I have never noticed any performance degradation when running a Socket 7 boards AGP port as a 66 MHz PCI slot.

Don't know man, maybe you are right in theory, but here, there is a malfunction a want to overcome, I can't be happy with this.
