Question

you are trying to quickly determine if a memory card is ecc - enabled by visually inspecting the card. what can you do to find out if the card is ecc - enabled?
determine if the number of memory chips is divisible by 3 or 5.
determine the memory cards capacity.
look for the memory standards printed on the card (such as ddr3 or ddr4).
check to see if the memory is single - sided or double - sided.

Explanation:

Error - correcting code (ECC) is related to memory standards. Looking for memory standards printed on the card (such as DDR3 or DDR4) can give clues about ECC - enabled status as some standards support ECC. The number of memory chips being divisible by 3 or 5 has no relation to ECC. Memory capacity does not indicate ECC - enabled status. Whether the memory is single - sided or double - sided also does not determine ECC status.

Answer:

Look for the memory standards printed on the card (such as DDR3 or DDR4).
