are supportedThe memory data path is 72-bit wide. The Intel 855GME Host Bridge supports
64 Mbit, 128 MByte, 256 MByte and 512 Mbyte SDRAM technologies with a maximum ROW
page size of 16 Kbytes and CAS latency of 2 or 2.5. The maximum height of the DIMM modules
possible on CP PIV is one inch or 25.4 mm.
The DDR interface runs at 100 MHz synchronously to the front side bus frequency. The SPD
(Serial Presents Detect) -SROM available on DIMM modules provide all necessary information
(speed, size, and type) to the boot-up software. The SPD-SROM can be read via SMBUS
connected to the Intel Hance Rapids South Bridge.
