You want to upgrade the memory in a database server, and the system documentation states that the motherboard requires ECC memory. Why is ECC memory important?
A) ECC memory is faster than non-ECC memory
B) ECC memory includes built-in error correction
C) ECC memory uses less power than non-ECC memory
D) There’s no significant difference between ECC and non-ECC memory
Answer: B) ECC memory includes built-in error correction
Error Correcting Code (ECC) memory can detect and correct memory errors in real-time. ECC memory is often used in large computing environment or on servers that require the highest level of uptime. ECC memory is generally more expensive than non-ECC memory, so you won’t usually find non-ECC RAM on a normal workstation or laptop computer.
There’s no discernable difference in power consumption or speed between ECC and non-ECC memory, but that doesn’t mean they aren’t functionally different. If you’re planning a memory upgrade, be sure you’re using the appropriate memory type and remember that you’ll never find ECC and non-ECC memory mixed together on the same system.
