Windows 98SE not 4X AGP, but 2X AGP

[egbertjan]

 

If I install a higher driver from Nvidia for my Geforce 4 ti 4600 on my Windows 98SE PC than version 45.23 then the PC switches back to 2xAGP. I have this driver version 4.38 from Via on it for the AGP port. Others via drivers unfortunately do not help to turn it into 4x agp again.

This is My Windows 98SE PC

Pentium 3 1400 mhz |
Video card: Geforce 4 ti 4600 128mb
Memory: 512 MB Memory
Motherboard: Shuttle AV18
SCSI adapter: Adaptec 29160N
HDD: ST373455LC
Sound card: Creative soundblaster live 1024

Here with 56.64

and here with 45.23

Who knows what I can do about this?

I need newer drivers from Nvidia for The Sims 2 and 3d mark 2003 to work properly.

Does Sims 2 & 3DMark03 work with the newer drivers? If the game works with newer drivers then it might be nothing too concerning. I know that the AGPx2 supply voltage is 3.3V & AGPx4 is 1.5V but this should not have changed with the updated driver as it would be a BIOS setting. The AGPx2 cards had a better chance of working in an AGP Universal slot than did the AGP cards slotted to fit AGPx4 port/slot only. It would be the maximum transfer clock divided by 2, 4 or 8 for different AGP modes. See if BIOS is set up for AGPx4 because the 56.64 driver says AGPx2 bus. It might be set for auto or a driver reporting error. Although it will not be a concern, I have used AGPx1 or x2 setting in BIOS & chose a small video memory window when card is not working properly. Your card is good most likely. Check 3Dmark03 and see if it gives a reasonable result. When updating driver install a standard graphics driver first, reboot then install other driver, this is important.

Did you try the 77.72 drivers? By the way, in my experience its better to reboot first after driver installation in safe mode and remove ALL Nvidia entries in MSconfig/ Startup.

I have tried different Via drivers, but nothing helped. I have the idea that the Nvidia drivers do something that makes them fall back on agp 2x

Already tried this fix?

You may also try RivaTuner, I think it has some options related to AGP:
