Page 175 Memory AMD-Based Systems Computers equipped with AMD-based processors come with Double Data Rate-Synchronous Dynamic Random Access Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs). DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 8GB (1-Gbit Technology) of memory configured in a high-performing dual channel mode.
