user is sure that the physical memory is 8GB and not 16GB.

 

Solution

why there is difference between the actual memory and log?

we found that the issue is that server didn't start successfully. and the memeory information in the log is the old memory information on this motherboard. so it could be different.

 

if the server didn't start successfully, we can't trust the configuration in the logs, becuase the logs only refer to the configuration last time when this motherboard start.
