nforce3 & Error 43 on AGP Video Card

[Brian K Lamb]

Has anyone seen upgraded chipset drivers for the nforce3? Currently have the
Vista included drivers installed.

I'm running the MSDN 64bit version of Home Premium on a Giga-Byte K8NS 939
Ultra MB with an AMX X2 4600+. Under the graphics card in Device manager, I
am getting the infamous Error 43 (Your device reported a problem and Windows
has disabled it) with both an ATI X800XT and an nVidia 6800GT. Workaround
is to limit Vista to 1 cpu core though MSCONFIG, but that leaves the system
a bit hobbled on horsepower.

I assume that you have the latest BIOS update for your MOBO and the latest
X2 driver update for your AMD CPU and are using the graphics card drivers
that installed with the RTM version of Vista.
What happens if you try using only 1 graphics card at a time?

Hi Brian,

install VistaBootPro and choose to use only one CPU.
It works.
