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. DIMM type and speed: PC3-10600U DIMM size (capacity) Number of DIMMs installed per microprocessor bank 1 to 3 1 GB, 2 GB, 4 GB 4 to 6 Microprocessor model Intel Xeon E5502, E5503, E5504, E5506, E5507 Intel Xeon E5603, E5606, E5607, E5520, E5530, E5540, E5620, E5630, E5640, X5647 Intel Xeon E5645, E5649, X5550, X5560, X5570, X5650, X5660, X5667, X5670, X5672, X5675, X5677, X5680, X5687, X5690, W5580, W5590 Intel Xeon E5502, E5503, E5504, E5506, E5507 Intel Xeon E5603, E5606, E5607, E5520, E5530, E5540, E5620, E5630, E5640, X5550, X5560, X5570, X5647, W5580, W5590 Intel Xeon E5645, E5649, X5650, X5660, X5667, X5670, X5672, X5675, X5677, X5680, X5687, X5690 Memory frequency 800 MHz 1066 MHz 1333 MHz 800 MHz 1066 MHz 1333 MHz Table 2.
