Appendix A. System Memory Speed - Lenovo ThinkStation P920 Hardware Maintenance Manual

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.
Refer to the following information about the system memory speed:
• Memory module types:
– DDR4 RDIMM
– DDR4 LRDIMM
– DDR4 3DS RDIMM
• Memory module operating voltage: 1.2 V
• Memory module frequency: 2666 MT/s
• Microprocessor models:
– Intel Xeon Platinum series
– Intel Xeon Gold series
– Intel Xeon Silver series
– Intel Xeon Bronze series
