紧接着我们的一个测试大项就是内存性能测试了，这里我们选择的是AIDA64 Memory & Cache Benchmark。其中我们选取内存性能测试的4项成绩：读取、写入、拷贝和延时。其中前三项成绩越高越好，延时成绩越低越好。其中带宽性能以100MB/s为一档，延时以0.1ns为一档。测试的实际结果如下：

在内存测试中，可能会有人队评分标准不解。在内存测试中由于有4个小项成绩，所以我们先对每一小项的成绩进行排名并打出小分，然后4项小分的成绩相加、排名，并最终根据排名给出最终的分数。虽然各款主板的内存性能差距并不大，但是映泰和华硕仍然技高一筹，获得最终的胜利。介于IVB平台强大的内存内存性能，所以各款主板的表现均让人满意。
