memtest86 +：跟踪奇偶错误，需要精巧的想法

好的，我真的希望有个聪明的人会向我提示正确的解决方案。我有一个HP Z420工作站，并且已经升级了内存。我之前有4x4GB，然后又购买了4x4GB。所有8x4GB都相同：“ Samsung 2Rx8 PC3-12800E-11-11-E3”。所以我的主板上有8个DIMM插槽。这些DIMM插槽是双通道的。DIMM插槽1 + 3 + 6 + 8涂成黑色（通道1），DIMM插槽2 + 4 + 5 + 7涂成白色（通道2）。我的旧4x4GB条位于黑色通道1 DIMM插槽内。我将新的4x4GB条形插入白色的通道2 DIMM插槽中。运行memtest时，出现以下消息：

929-Fatal MCA error.
    HA error detected CPU 0 DIMM Slot 5 or 6
    Memory read error - DB parity error

之后，我尝试了不同的配置来跟踪该错误，但是到了死胡同，我需要聪明人的帮助：)这是我的测试摘要的图片，其描述如下：

Column B: old bars inside the black channel 1, new bars inside the white channel 2. Fails with the message that I have posted earlier.

Column C: testing only the old bars with memtest, it works

Column D: testing only the new bars with memtest, it works. that "4 / 78%" means that I let memtest run until pass 4 at 78% before I stopped it. I forgot to document that at column C.

重要的临时结论：旧的和新的内存条都可以工作！因此，当我混合它们时似乎出现了问题。

Column E: mixing 3 new and 1 old (only black / channel 1): works!

Column F: mixing old and new in dual channel slot 5+6: fails! (forgot to document the slots from the error message though, that's why there's only a red field without description)

Column G: mixing old and new in dual channel slot 3+4: fail!

Column H: mixing old and new in dual channel slot 1+2: fail!

临时想法：在双通道中混合新旧总是失败的，难道是我需要将新旧通道放到自己的双通道中吗？不应有任何区别，因为所有8个钢筋的规格都相同，但看起来确实如此。

Column I: swapping the bars between slot 2 and 3 from column H. So now the new bars are in the same dual channel: works! yay, my theory seems right.

Column J: group the new bars in a dual channel and group the old bars in a dual channel: fails againnnnnnn omg I want to cry ;_;

我的想法用光了，我在错误消息中看不到任何模式。有人有个好主意/评论吗？我的意思是看C和D栏：所有RAM棒都很好！然后我在F列至H列中进行混合，但它们失败了，但是一旦我以“正确的方式”对其进行混合（列I）。但话又回来了（J列）。这是怎么回事，我太笨了：/
