Save it with the file name:
"viaagp4xon.reg" (without quotes) and run the file to edit your registry.
Be aware though that the P3V4x can be unstable at AGP4x and that is why it`s disabled by default beginning with the 4.16 nVidia drivers. If the drivers detects a VIA (Apollo Pro) chipset, it defaults to 2x.
I have a P3V4x and the difference between 2x and 4x is minimal at best (a couple of FPS on ocasion) and not worth the potential unstability.
On mine, I ran a GeForceDDR at 4x with absolutely no problems. Now, I`m running a GeForce3 and have to run at 2x due to some unstability.
Some games will run fine at 4x and others will simply not run.
My advise to you would be to try 4x and if there`s no trouble, fine. Otherwise, disable it and forget it.
