Switching 2 x AGP 2 to 1x AGP in W2K

[Hike]

Is there any other way for setting AGP Modus to 1x then with Powerstrip, With that the PC just hangs, when I try to set it to 1x AGP.
I want to try this because I got random lockups in 3D (NFS Porsche, 3DMark 2K) with my system at 133MHz FSB. Everything in 2D Modus is working w/o a problem.

My specs:
P3B-F P3-600 @ 800MHz, G400Max @ 89MHz 2xAGP

KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Service s\G400\Device0\Mga.AGPFlags
04 01 00 00 ¡¡autoset 1x/2x
01 01 00 00 ¡¡force AGP1X
00 00 00 00 ¡¡force AGP2X

just run regedit. and change the key to "00 00 00 00 ¡¡force AGP2X ". and reboot system.
ur g400 must be 2x agp mode.

Howdy AVP, it seems I have only AGP@1x on W2K, yet 98 is purring along with 2x. I have ACPI enabled, can i still enable AGPx2 through the registry?
Mga.AGPFlags
01 01 00 00
with no other entries, with regedit I could not figure out how to add extra entry lines in the Mga.AGPFlags Key
I also have this Key:
User.AGP is set at
01 00 00 00
