Q: Is there any limitation of using DDR/SDRAM modules on AT7/AT7E?
A:
  1. Supports 6 banks up to 3 GB DRAMs for unbuffered DDR/SDRAM modules. (PC 1600/2100)
  2. Supports 4 banks up to 2 GB DRAMs for unbuffered DDR/SDRAM modules. (PC 2700)
  3. Supports 8 banks up to 3.5 GB DRAMs for registered DDR/SDRAM modules. (PC 1600/2100)
  4. Supports 6 banks up to 3 GB DRAMs for registered DDR/SDRAM modules. (PC 2700)
  5. When using DDR SDRAM, please use DIMM1 first ,or follow our recommendation in DDR memory test report which published on web page.
  6. AT7 does not support using both unbuffered DDR and registered DDR at the same time.
