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.
