Appendix B. System Memory Speed - Lenovo 415711U - THINKSTATION S20 TWR W3520 2.8G User Manual

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.
