Appendix C: DIMM COMPATIBILITY
In order to clear the memory recognize half of size to VIA CN700/CX700
platform, the following information is the description of chipset structure respect
to memory’s design affect to system board.
‧ Advanced High-Performance DDR2 SDRAM Controller
– DDR2 Mode
– Supports DDR2 533 / 400 memory
– Supports mixed 64 / 128 / 256 / 512 / 1024 Mb SDRAM in x8 or x16
configurations
– Supports CL 2 / 3 / 4 / 5 for DDR2 533 / 400
– Supports 1 unbuffered double-sided DIMMs (4 banks) and up to
1 GB of physical memory
As VIA CN700 chipset design only supports BA0~1 signals, therefore, it
supports 4 banks memory design. The 8 banks memory design can not support
due to chipset design without BA2 signals, on the other word, one DIMM socket
design support 1GB (max).
