Memory upgrade: ECC or non-ECC? Buffered or unbuffered?

[hpinvegas]

Hi group,

My Pavilion has 16GB of memory; I want to take it to its maximum 32GB, so I'm looking to buy two 16GB sticks of memory.

The specs say I should look for PC4-21300, DDR4 2666. 

It says nothing about ECC or non-ECC; also, unsure whether I'm looking for buffered or unbuffered memory.

Any help would be appreciated. Thanks.

Hi:

You want non-ECC, unbuffered memory.

Here is the link to the Crucial memory report for your model PC.  They guarantee compatibility...
