Appendix A. System memory speedThe Intel Xeon® microprocessor families compatible with this ThinkStation computer feature an integratedmemory controller, which provides the microprocessor with direct access to the system memory. Becauseof this design, the system memory speed will be determined by a number of factors, including themicroprocessor model and the type, speed, size (capacity), and number of DIMMs installed. Refer to thefollowing table for the information on the supported system memory speed for your own computer model.Table 1. DIMM type and speed: UDIMM PC4-2400-EDIMM operating voltage Microprocessor model Memory frequency1.2 VIntel Xeon E5-2699 v4, E5-2698 v4,E5-2697A v4, E5-2697 v4, E5-2695v4, E5-2690 v4, E5-2689 v4, E5-2683v4, E5-2680 v4, E5-2667 v4, E5-2660v4, E5-2658 v4, E5-2650 v4, E5-2643v4, E5-2637 v4, E5-2650L v4,E5-2648L v4, E5-1680 v4, E5-1660v4, E5-1650 v4, E5-1630 v4, E5-1620v42400 MHz1.2 VIntel Xeon E5-2640 v4, E5-2630v4, E5-2630L v4, E5-2628L v4,E5-2623 v4, E5-2620 v4, E5-2618Lv4, E5-1650 v3, E5-1620 v3, E5-1607v4, E5-1603 v42133 MHz1.2 V Intel Xeon E5-2620 v3, E5-2609 v4,E5-2608L v4, E5-2603 v4 1866 MHz1.2 V Intel Xeon E5-2609 v3 1600 MHzTable 2.
