    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). The memory sockets on the system board can be populated with industry-standard DIMMs. These memory module slots are populated with at least one pre installed memory module. To achieve the maximum memory support, you may be required to replace the pre installed DIMM with a higher capacity DIMM.

  • Page 172

    Memory The following processor bus frequencies are required for the system to run at the supported memory frequencies. Memory Frequency 266 MHz 333 MHz 400 MHz If a memory frequency is paired with an unsupported processor bus frequency, the system will run at the highest supported memory speed.

  • Page 173

    The system will automatically operate in single channel mode or a higher-performing dual channel mode, depending on how the DIMMs are installed. ■ In single channel mode, the maximum operational speed is determined by the slowest DIMM in the system. For example, if the system is populated with a DIMM that is 266 MHz and a second DIMM that is 333 MHz, the system will run at the slower of the two speeds.
