Appendix A. System Memory Speed - Lenovo ThinkStation P520 Hardware Maintenance Manual

Appendix A. System memory speed

®
The Intel Xeon microprocessor families compatible with this ThinkStation computer feature an integrated
memory controller, which provides the microprocessor with direct access to the system memory. Because of
this design, the system memory speed will be determined by a number of factors, including the
microprocessor model and the type, speed, size (capacity), and number of DIMMs installed.
Notes:
• The actual system memory speed of the memory modules varies depending on the microprocessor
model. For example, your computer comes with 2666 MT/s memory modules, but microprocessor only
supports up to 2400 MT/s memory modules. Then the system memory speed will be no faster than 2400
MT/s.
• The microprocessor models supported in your computer might vary. For a list of supported
microprocessor models, contact the Lenovo Customer Support Center.
