I have a i7 920 cpu on a DX58SO motherboard.
Reading the specs of these, I concluded that the maximum RAM capacity should be 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
However, dmidecode on Linux reports that the maximum capacity is 8 Gb.
Does someone have a hint about where this difference may come from? Maybe the BIOS should be updated? Thanks in advance.
Below some output from dmidecode:
