Good article, the customer's system also encountered the same problem, linux5.4 only recognized 32g, the system boot has seen the recognition of 64g, but only 32g on os.

A question and answer from Baidu:

How does linux recognize more than 32 GB of memory

In theory, a 64-bit CPU can use more than 32 gigabytes of memory, but if you install a virtualization service, more than 32 gigabytes of memory is missing. You can remove virtualization services to solve the problem. Special statement: because my computer doesn't have that much memory, I haven't tried it. I just know it.
