1.2 Computer Components
System Memory Options
The main memory subsystem supports a minimum standard 128 MB of Synchronous
SDRAM, expandable to 640 MB. The minimum standard Synchronous SDRAM is
integrated on the system board. The upgrade SDRAM is accomplished with memory
expansion boards that are available in 32-, 64-, 128-, and 256-MB.
The memory expansion slot cover is secured to the computer by a slotted Torx T-8
screw. A tamper-resistant security screw, included with the computer, can be used to
provide added security. A security wrench, also included with the computer, must be
used to remove the tamper-resistant security screw.
System memory can be upgraded as shown in Table 1-2.
