The GMCH supports a maximum of four rows ofmemory. For the purposes of this discussion, a “side” of a DIMM is equivalent to a “row” ofSDRAM devices.The memory bank address lines and the address lines allow the GMCH to support 64-bit wide x8and x16 DIMMs using 128-Mb, 256-Mb, and 512-Mb SDRAM technology.For the DDR SDRAM interface, Table 25 lists the supported configurations. Note that the GMCHsupports configurations defined in the JEDEC DDR DIMM specification only (A, B, C). Non-JEDEC standard DIMMs (e.g., double-sided x16 DDR SDRAM DIMMs) are not supported. Foradditional information on DIMM configurations, refer to the JEDEC DDR DIMM specification.Table 25.
