I recently purchased an Aopen AX4C Max motherboard, a Chaintech XF Geforce 5200 Ultra video card and 2 dimms of DDR 400 memory. This board has the Intel 875P chipset and does dual memory so the pathway is 128K instead of 64K. The system would not run with both Dimms installed even with the latest nVidia drivers. It runs nicely with only one Dimm installed. Earlier nVidia drivers tried as well. It appears to me that nVidia is unable to handle the dual DDR memory at present. Does anyone know what I can do to make the Dual DDR memory work?
