When deciding on which type of RAM to add, which of the following considerations are TRUE? Choose all options that are TRUE.
A.
You can use Error-Correcting Code (ECC) and non-ECC memory modules interchangeably.
B.
If your server boards are designed specifically for use with ECC memory modules, you cannot mix ECC memory modules with non-ECC memory modules.
C.
If your server boards are designed for use with non-ECC modules, you could install ECC memory modules because there is a possibility that it might work.
D.
All of the above.
Explanation:
The rules for using ECC and non-ECC memory modules are simple: If your server boards are designed specifically for use with ECC memory modules, you cannot mix ECC memory modules with non-ECC memory modules. You should always avoid situations that require mixing of ECC and non-ECC memory modules. However, if your server boards are designed for use with non-ECC modules, you could install ECC memory modules because there is a possibility that it might work.
Incorrect
Answers:
A: The recommendation is to NOT use ECC and non-ECC memory modules interchangeably. This is because of the chipset installed on the server board indicating the use of one memory module or the other.
