RAM 信息与 dmidecode --type 17

Question

在华硕V-PRO Z77主板上安装了2x2（金士顿和海盗船）内存插槽。所有四个 RAM 板条都不会引起任何投诉。他们工作正常。但是，下面是运行 dmidecode 程序的结果输出，在输出中我对以下几行感兴趣：
错误信息句柄：0x0060
错误信息句柄：0x0063
这是什么意思？
这些错误的原因是什么？
不幸的是，我无法在 Google 中找到有关此的信息。

$ sudo dmidecode --type 17
# dmidecode 2.12
# SMBIOS entry point at 0x000f04c0

Answer 1

您可以查看可用的 dmidecode 源 online:

    case 17: /* 7.18 Memory Device */
        printf("Memory Device\n");
        if (h->length < 0x15) break;
        if (!(opt.flags & FLAG_QUIET))
        {
            printf("\tArray Handle: 0x%04X\n",
                WORD(data + 0x04));
            printf("\tError Information Handle:");
            dmi_memory_array_error_handle(WORD(data + 0x06));
            printf("\n");

好的，所以 Error Information Handle: 来自一些数据结构偏移量 0x06，可能是一些 dmi 数据，因为程序名为 dmidecode。
我们在 dmi 规范中搜索偏移量 0x06：SMBIOS specification section 7.18 Memory Device (Type 17) in Table 71 - Memory Device (Type 17) Structure 我们找到 Memory Error Information Handle with description:

The handle, or instance number, associated with
any error that was previously detected for the
device. if the system does not provide the error
information structure, the field contains FFFEh;
otherwise, the field contains either FFFFh (if no
error was detected) or the handle of the errorinformation
structure. See 7.18.4 and 7.34.

在 7.34 64-Bit Memory Error Information (Type 33) 部分，您可能会找到 Table 100 - 64-Bit Memory Error Information (Type 33) structure。

所以 dmidecode --type 17 中的 Error Information Handle: <handle> 输出意味着在你的存储卡的 dmi 结构的 Memory Error Information Handle 中有一个值。这意味着您的 BIOS 检测到与存储卡相关的错误，句柄 0x0060 和 0x0063 可用于检索有关上次检测到的错误的错误信息结构。无论如何尝试 dmidecode --type 33 进一步调查。
