poweredge 12G r720是dell的机架式服务器，俗称刀片机。

一）当使用1个cpu，也就是单cpu时，32G内存的内存槽插法：
2条16G内存的话，分别插在A1，A3内存槽。
4条8G内存的话，分别插在A1，A2，A3，A4内存槽。
8条4G内存的话，分别插在A1，A2，A3，A4，A5，A6，A7，A8内存槽。

二）当使用2个cpu，也就是双cpu时，64G内存的内存槽插法：
4条16G内存的话，分别插在A1，A3和B1，B3内存槽。
8条8G内存的话，分别插在A1，A2，A3，A4和B1，B2，B3，B4内存槽。
16条4G内存的话，分别插在A1，A2，A3，A4，A5，A6，A7，A8和B1，B2，B3，B4，B5，B6，B7，B8内存槽。

DELL R720手册第44页开始，有内存安装的基本原则和单/双CPU时内存的插法。

单CPU：
2x16GB，A1，A3
4x 8GB，A1，A2，A3，A4
8x 2GB，A1-A8

双CPU：
与单CPU时A槽对应插在B槽位。
