Inst alling Addi tional Memo ry The com puter comes wi th double data rat e 2 synchrono us dynamic random a ccess me mory (DDR2 - SDRAM) dual inli ne memor y modules (DIMMs). DIMMs The memo ry sockets on the sy stem board can be populated wit h up to four industr y-standard DIMMs.
Populating D IMM Sockets There are four DIMM socket s on the system boa rd, with two sock ets per channel. Th e sockets are labeled XMM1, XMM2, XMM3 , and XMM4. So ckets XMM 1 and XM M2 opera te in mem ory cha nnel A. Socke ts XMM3 and XMM4 operate in memory channel B.
should be populated with the two 512MB DIMMs. With this confi guration, 2 GB will run as du al channel and 256 M B will r un as sin gle chan nel. ● In any mode, the maxim um operational speed is determined by the slowest DIMM in the sys tem. Installing DIMMs CAUTION You mu st disconne ct the power cord befor e adding or remov ing memor y modules.
8. Open both latches o f the me mory mo dule socket ( 1), and in sert the me mory modu le into the socket (2). Figu re 2 -6 Installing a DIMM NOTE A me mory module can be insta lled in only on e way. Matc h the notch on the module with the tab on the m emory socket.
