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. System memory speed DIMM Type and Speed DIMM Size (Capacity) Number of DIMMs Installed Microprocessor Model Intel Xeon E5502 Intel Xeon E5503 Intel Xeon E5504 Intel Xeon E5506 Intel Xeon E5507 Intel Xeon E5520 Intel Xeon E5530 Intel Xeon E5540 Intel Xeon E5620 Intel Xeon E5630 Intel Xeon E5640 Intel Xeon X5550 Intel Xeon X5560 Intel Xeon X5570 Intel Xeon X5650 Intel Xeon X5660 Intel Xeon X5667 Intel Xeon X5670 Intel Xeon X5677 Intel Xeon X5680 Intel Xeon W3503 Intel Xeon W3505 Intel Xeon W3520 Intel Xeon W3530 Intel Xeon W3540 PC3-10600U 1 GB, 2 GB, 4GB 1 to 3 4 to 6 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1333 MHz 1066 MHz 1333 MHz 1066 MHz 1333 MHz 1066 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1333 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz PC3-8500U 1 GB, 2 GB, 4GB 1 to 6 800 MHz 800 MHz 800 MHz 800 MHz 800 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz 1066 MHz © Copyright Lenovo 2008, 2012 257
