买了4条三星64GB DDR3 1600Hz LRDIMM
AIDA64得出结果如下

我看之前的帖子别人E5-2670双路两个四通道能跑100GB/s
BIOS Auto是行1066 Hz
似是1066 Hz刷1600Hz的...

插两条双通道呢?

应该是插槽插错了,只有双通速度
人家那是双路四通

双通道跑不到30g。

以前用过x79四通50g

8r*4,直接降到1066了

你这个等于一个槽插了四条,当然降速了
 楼主| 发表于 2022-8-21 00:05 | 显示全部楼层
看来这速度是正常的
如果四条插满双通道会不会好一点?

按1600频率算,1600 × 4 × 64 / 8 = 51.2 GB/s。这样也就基本上匹配了你说的别人双路跑超过100

看看是不是Hyper-V开了或者Memory Integrity开了,这两个都会对内存测试形成不小的影响
