內(nèi)存升級問題

xfgavin

大家好，

小弟最近想為我們的DELL R720升級內(nèi)存。 目前的內(nèi)存是Kinston 1333 8G 1.35v ECC+REG, 型號是KP9RN2-HYC。奇怪的是北京那邊很難找到相同型號的內(nèi)存條。所以只好試著用Kinston類似的條子，目前每個CPU多個了一根Kinston 1333 8G 1.5v ECC+REG，型號是9965434-058.A00LF。
服務(wù)器系統(tǒng)是Debian 8 64bit
服務(wù)器到現(xiàn)在沒有發(fā)現(xiàn)明顯的問題，即便用memtester2測試了幾天也沒出什么問題。不過在dmesg里有時可以看到如下的輸出：
請問這些輸出是什么原因造成的？是kernel的問題還是內(nèi)存兼容性的問題？
