Upgrade Sockets

The system board has the following upgrade sockets:

Tprocessor socket DIMM sockets.

See the following paragraphs for socket descriptions.

Processor Socket

The processor Slot 1 socket is designed for easy processor upgradeability through use of a Single Edge Contact (S.E.C.) cartridge and a universal retention mechanism. The cartridge contains the processor, second level cache, thermal plate, back cover, and heatsink.

The 242-pin edge connector Slot 1 socket on the system board holds the processor cartridge. The cartridge is held in place in the socket by the universal retention mechanism.

To remove or install a processor cartridge, see Section 3, “Disassembly and Reassembly.”

DIMM Sockets

The system board has two, 168-pin, gold-plated DIMM sockets (locations are shown on the figure at the beginning of this section). The sockets support up to 256 MB of high-speed SDRAM memory. The sockets support DIMM modules in 16-, 32-, 64-, and 128-MB unbuffered non-ECC memory configurations.

The DIMM modules

can be installed in one or two sockets

size can vary between sockets

Tspeed must match the processor bus speed (66 MHz or 100 MHz) can be single- and double-sided.

See the following tables for supported DIMMs and for sample DIMM upgrade paths. To determine the memory needed for a memory upgrade, see “Checking System Memory” in this section. To remove or install a DIMM, see Section 3, “Disassembly and Reassembly.”
