内存升级问题
大家好，小弟最近想为我们的DELL R720升级内存。 目前的内存是Kinston 1333 8G 1.35v ECC+REG, 型号是KP9RN2-HYC。奇怪的是北京那边很难找到相同型号的内存条。所以只好试着用Kinston类似的条子，目前每个CPU多个了一根Kinston 1333 8G 1.5v ECC+REG，型号是9965434-058.A00LF。
服务器系统是Debian 8 64bit
服务器到现在没有发现明显的问题，即便用memtester2测试了几天也没出什么问题。不过在dmesg里有时可以看到如下的输出：
请问这些输出是什么原因造成的？是kernel的问题还是内存兼容性的问题？
