Installing System Board Options 8-58. If you are relocating or removing an EISA expan-sion card, start the EISA Configuration Utility,and delete the expansion card from the configura-tion information.See Chapter 5, “Using the EISA Configuration Util-ity,” in the User’s Guide for instructions.NOTE: If you removed a PCI expansion card, thesystem automatically performs any required re-configuration tasks during the boot routine.Adding MemoryThe eight dual in-line memory module (DIMM) sockets onthe system board can accommodate 64 to 512 megabytes(MB) of dynamic random-access memory (DRAM). DellPowerEdge 4200 systems use 72-bit, buffered, extended-data out (EDO) DIMMs in these 168-pin sockets. TheDIMM sockets are located near the right edge of the sys-tem board (see Figure 8-1).Memory Upgrade KitsThe system is upgradable to 512 MB by installing combi-nations of 32- and 128-MB DIMMs. The DIMMs shouldbe rated at 60 nanoseconds (ns) or faster. Memoryupgrade kits can be purchased from Dell as needed.NOTE: Dell PowerEdge 4200 systems do not supportmore than 512 MB of RAM. If you install more than512 MB of RAM, the excess memory will not be used.DIMM Installation GuidelinesStarting with the socket farthest from the microprocessorguide bracket assemblies, the DIMM sockets are labeled“DIMM_A” through “DIMM_H” (see Figure 8-1).When installing DIMMs, follow these guidelines:• Install a DIMM in socket DIMM_A before socketDIMM_B, socket DIMM_B before socketDIMM_C, and so on.• If you install different sizes of DIMMs, install themin order of descending capacity, beginning withsocket DIMM_A.• DIMMs need not be installed in pairs.Table 8-1 illustrates several sample memory configura-tions based on these guidelines.Table 8-1.
