linux - 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，因为程序被命名为 dmidecode。
我们在 dmi 规范中搜索偏移量 0x06:SMBIOS specification节7.18 Memory Device (Type 17)在 Table 71 - Memory Device (Type 17) Structure我们找到Memory Error Information Handle附描述:

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)部分你可能会发现Table 100 - 64-Bit Memory Error Information (Type 33) structure .

所以 Error Information Handle: <handle>在 dmidecode --type 17 output 表示 Memory Error Information Handle 中有一个值你的存储卡的 dmi 结构。这意味着您的 BIOS 检测到与您的存储卡和句柄相关的错误 0x0060和 0x0063可用于检索有关最后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。
