You are replacing failed ECC RAM sticks in a server that currently has ECC RAM installed. The only replacement RAM available is non-ECC RAM, which is otherwise identical. Mixing ECC and non-ECC RAM in the same server is possible, but error checking will no longer function for any of the RAM, though the server will recognize and use all RAM installed.

You are replacing two failed sticks of memory in a server- The server (2).docx
1. You are replacing two failed sticks of memory in a server. The server has ECC RAM installed
because of the error checking feature available. The only replacement RAM you have available
is non-ECC RAM, which is otherwise identical to the RAM in the server. Should you replace the
failed ECC RAM sticks with non-ECC RAM, mixing both ECC and non-ECC RAM in the same
server machine?
A. Yes. As long as there are at least two pairs of ECC RAM in the server, the error checking
feature will remain active.
B. Yes, but although all of the RAM will be recognized by the server and work with no
problems, error checking will not be available.
C. No, because the server will not recognize the non-ECC RAM. All of the RAM needs to be
either ECC or non-ECC.
D. No, because none of the RAM will be recognized and the server will fail to boot.
Solution
B. You can substitute non-ECC RAM for ECC RAM and mix both types together, but all the
memory will run as non-ECC and error checking will not occur.
