Memory
CP PIV memory uses DDR SDRAM technology. The CP PIV provides
a maximum of two GBytes using two verticall DIMM sockets to install
off-the-shelf DIMM modules. CP PIV only supports DDR SDRAM DIMM
memory with a supply voltage of +2.5V.
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.
