Lenovo ThinkStation P920 Tower Workstation - Manual (Page 153)

Appendix A. System memory speed
The Intel Xeon ® microprocessor families compatible with this ThinkStation computer feature an integrated
memory controller. The memory controller provides the microprocessor with direct access to the system
memory. Therefore, the system memory speed will be determined by the memory module type, frequency,
size (capacity), the number of memory modules installed, and the microprocessor model.
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.
