Intel ISP1100 manual Memory, Supported Processors

Processors

The server board supports a single Intel Pentium III processor or Celeron processor that plugs into a PGA370 socket connector that secures the processor chip with a zero-insertion-force (ZIF) arm. The host bus speed (66 MHz or 100 MHz) is automatically selected. Table 2 lists the processors supported by the server board.

NOTE

The server board supports Pentium III processors with a 100 MHz host bus and Celeron processors with a 66 MHz host bus. Processors with a 100 MHz host bus should be used only with 100 MHz SDRAM. The server board may not operate reliably if a processor with a 100 MHz host is paired with

66 MHz SDRAM. However, processors with a 66 MHz host can be used with either 66 MHz or 100 MHz SDRAM.

Memory

The server board has four DIMM sockets. The BIOS determines the SDRAM size and speed using the serial presence detect (SPD) data structure programmed into an EEPROM on the DIMM. Memory size is 16 MB to 1 GB. DIMM board memory size can be mixed but must be either all unbuffered or registered. Slot vacancies are allowed.

The server board supports the following memory features:

∙168-pin SPD DIMMs with gold-plated contacts.

∙66 MHz or 100 MHz unbuffered or registered SDRAM, 72-bit ECC, 3.3 V only memory.

∙Single- or double-sided DIMMs in the sizes listed in Table 3.
