4.4 Memory Guidelines for AMD Athlon™ 64
Processor-Based Systems
AMD Athlon 64 processor-based platforms may be designed to leverage industry standard DDR
registered DIMMs and unbuffered DIMMs, depending on processor type and motherboard design.
An independent testing company, Computer Memory Test Labs (CMTL), has conducted memory
compatibility testing. CMTL is an independent test facility and is able to test RAM modules from
different module suppliers. System builders should access the CMTL web site at
http://www.cmtlabs.com
motherboard manufacturer and motherboard model.
Note: The CMTL website is provided for informational purposes only, and AMD recommends that
a system builder conduct its own testing and validation to confirm that the memory modules
are suitable for its systems.
Several AMD Athlon 64 processor-based motherboards currently support some of the following
memory features:
• PC1600, PC2100, PC2700, and PC3200 registered and unbuffered memory modules
• 184-pin 2.5-V and 2.6-V DDR DIMMs
• 28-bit DDR memory bus
• 64-Mbyte, 128-Mbyte, 256-Mbyte, 512-Mbyte, 1-Gbyte, 2-Gbyte and 4-Gbyte memory
technology
• Production DIMMs from industry standard DRAM memory manufacturers—The use of
registered or unbuffered types of DIMMs should match the type for which the motherboard
was designed.
