Front panel connector pin assignments 165MemoryCP PIV memory uses DDR SDRAM technology. The CP PIV providesa maximum of two GBytes using two verticall DIMM sockets to installoff-the-shelf DIMM modules. CP PIV only supports DDR SDRAM DIMMmemory with a supply voltage of +2.5V.are supportedThe memory data path is 72-bit wide. The Intel 855GME HostBridge supports 64 Mbit, 128 MByte, 256 MByte and 512 Mbyte SDRAMtechnologies with a maximum ROW page size of 16 Kbytes and CASlatency of 2 or 2.5. The maximum height of the DIMM modules possibleon CP PIV is one inch or 25.4 mm.The DDR interface runs at 100 MHz synchronously to the front side busfrequency. The SPD (Serial Presents Detect) -SROM available on DIMMmodules provide all necessary information (speed, size, and type) to theboot-up software. The SPD-SROM can be read via SMBUS connected tothe Intel Hance Rapids South Bridge.Front panel connector pin assignmentsCOM1 and COM2 portsThe physical interface for the COM1 and COM2 ports to the front panel isthrough a stacked dual Male DB9 Connector.
