我的 DX58SO 主板上有一个 i7 920 CPU。
阅读这些规格后，我得出结论，最大 RAM 容量应该是 16 Gb。 https://ark.intel.com/content/www/us/en/ark/products/37147/intel-core-i7-920-processor-8m-cache-2-66-ghz-4-80-gt-s-intel-qpi.html https://www.intel.com/content/www/us/en/support/articles/000005844/boards-and-kits/desktop-boards.html
但是，Linux 上的 dmidecode 报告最大容量为 8 Gb。
有人能提示一下这种差异可能来自哪里吗？也许应该更新 BIOS？提前谢谢。
以下是 dmidecode 的一些输出：
