VIA KX133 and 694X Chipsets With AGP 2X
On Athlon motherboards with the VIA KX133 or 694X chipset, such the ASUS
K7V motherboard, NVIDIA drivers default to AGP 2X mode to work around
insufficient drive strength on one of the signals.
• On Windows 9x systems, the registry key
HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System\
EnableVia4X
can be created to force NVIDIA drivers to use AGP 4X transfers.
• On Windows NT 4.0 and Windows 2000 systems, the registry key is
HKLM\System\CurrentControlSet\Services\nv4\DeviceN\ EnableVia4X
where the N in DeviceN is the system-determined number indicating the
current NVIDIA device. This number is normally 0.
These registry keys should only be used if there is reason to believe that the
motherboard has the appropriate drive strength.
