Detonator drivers turn off 4X AGP

[bluezebra1098]

Using Guillemot's 3.77 I get 4X AGP in SisSandra but using Nvidia's 6.26 the AGP setting is turned down to 2X AGP. The games look better using the Nvidia's drivers and my 3dMark score went from 4870 to 5231 but why are they turning the AGP down to 2X? I am using the VIA AGP 4.03 installed in "turbo" mode.

P3 667mhz, 256mbCrucial, P3V4X-1003, Guillemot 3d Prophet DDR,

I would think after looking at some threads it has to do with sidebanding being enabled in the bio also fast writes... try turning them off and check it then... .02

Yes, the Det3 drivers (6.xx) turn off the AGP4X.
To re-enable it, you have to hack the registry.

Navigate to HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System and create a new DWORD called EnableVia4X and give it a value of 1.

This should get you back to 4X.

Let us know how you make out.

I'll let you in on a little secret...AGP4x doesn't mean Jack Squat anyway

Hmmm... With 6.18 my Geforce2 MX wouldnt run 4x on my A7V, but with the 6.26 my Geforce2 MX runs at 4x. I didnt even do any registry changes, guess im lucky or something if Det3 suppose to disable 4x.

KGB MAN is the hero on this one....
Did the registry hack and I'm back to 4X!!!and yes I know it doesn't make that much of a difference but it makes me happy!

I am running the 6.26 with 4x and fast writes no problems at all - YET! 3D Mark went to 7102 from 6967 with 2x and the 6.18 drivers.

I'm running 6.26 with my DDR and my registry doesn't have the Registry Hack. But my CLAP is running 4x. Must be because of Creative's AGP Wizard....
