Memory

DDR4 memory voltage limitations

We recommend using memory that adheres to the JEDEC memory specification. Anything over the specified voltage can damage the processor or significantly reduce the processor life span.

For DDR4 memory: 1.2 volts, plus or minus 5%.

Error Correcting Code (ECC) 

ECC support depends on the motherboard and chipset.  If your processor is supporting ECC, you need to check with your motherboard vendor if they are also supporting it.
