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.
✎
The memory available may be limited by the operating system.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM DIMMs,
the DIMMs must be:
■ industry-standard 184-pin
■ unbuffered PC3200 400 MHz-compliant
■ 2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■ support CAS latency 3 (CL = 3)
■ contain the mandatory JEDEC SPD information
In addition, the computer supports:
■ 128Mbit, 256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies
■ single-sided and double-sided DIMMS
■ DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM
are not supported
✎
The system will not start if you install unsupported DIMMs.
