Default Re: Nvidia Linux Driver + 8800GTX + 4gigs of ram = No write combining

You don't need to tweak the MTRR configuration, the NVIDIA Linux graphics driver will ensure that the correct memory types are used when it creates CPU mappings of video memory. Have you tried setting the InitialPixmapPlacement NV-CONTROL property to "2"?
