Appendix B. 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. Refer to the following table for the information on the supported system memory speed for your own computer model. Table 1.

Appendix B. 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. Refer
to the following table for the information on the supported system memory speed
for your own computer model.
