Appendix A. System memory speed

® ®
The Intel Xeon or Intel Core
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
or memory type/configuration. For example, if your computer comes with three or four dual Rank 3200
MT/s memory modules, then the system memory speed may be no faster than 2933 MT/s.
• Processor DDR4 2DPC is supported when channel is populated with the same DIMM part number.
Symmetric configurations are required for 2DPC within one channel. Vendor mixing within a channel is not
allowed.
• The microprocessor models supported in your computer might vary. For a list of supported
microprocessor models, contact the Lenovo Customer Support Center.
• The ECC memory modules are not supported on the computer models with Intel Core i3, i5, i7, or i9
microprocessors.
Refer to the following information about the system memory speed:
• Memory module types:
– DDR4 ECC UDIMMs
– DDR4 non-ECC UDIMMs
• Memory module operating voltage: 1.2 V
• Memory module speed: 3200 MT/s
