AMD 30925 manual Memory Guidelines for AMD Opteron Processor- Based Systems

Page 35

30925 Rev. 3.04 February 2004	Builder’s Guide for AMD Opteron™ Processor-
	Based Servers and Workstations

AMD strongly recommends that the operation of the power supply is investigated and fully understood by the system builder to meet the requirements of each configuration. Verification of mechanical fit with the selected power supplies and other system components should also be investigated by the system builder prior to purchase.

Additional information on AMD Opteron™ Processor configuration is available at

www.amd.com/configuration. In EMEA, please visit http://www.amd.com/opteronhardware. These

documents that are additional resources designed to provide guidance to you with the configuration of a stable AMD Opteron™ processor-based platform.

5.4Memory Guidelines for AMD Opteron™ Processor- Based Systems

AMD Opteron processor-based platforms may be designed to leverage industry standard DDR registered DIMMs. 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 and view the recommended memory module list for the specific 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 Opteron processor-based motherboards currently support some of the following memory features:

•PC1600, PC2100, PC2700, and PC3200 registered 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.—Only registered- type memory modules should be used.

5.5AMD Opteron™ Processor Information

AMD Opteron processors are identified by a three digit model number, xyy, where: x—Indicates the maximum scalability of the processor. In other words:

100 series = 1-way servers and workstations
