The DRAM Controller uses the JEDEC standard Serial Presence Detect (SPD) mechanism to detect memory and array configurations; no jumper settings are required for the memory size. Memory is automatically detected by the system BIOS.
Rules for adding SDRAM memory modules to the DIMM memory array are as follows:
■The DIMM sockets support either single or
■The installed DRAM type can be 32 MB, 64 MB, 128 MB, or 256 MB DIMMs.
■The installed DRAM can be either PC100 or PC133. The maximum operation speed of the memory array is 133 MHz.
■DIMM sockets can be populated in any order.
■The DRAM Timing register, which provides the DRAM speed grade control for the entire memory array, will be programmed to use the timings of the slowest DRAMs installed.
Memory Module Installation
CAUTION: Your memory module sockets have gold metal contacts. When upgrading your memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.
CAUTION: Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. Refer to Appendix C, “Electrostatic Discharge,” for more information.
CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.
