I originally posted this question as a reply to a past thread of mine, but I think this actually qualifies as a new question, so am creating a new thread:
I'm upgrading RAM for my laptop 'HP 15-AY014TU', which has its compatible upgrades on this Crucial webpage:
http://www.crucial.com/usa/en/compatible-upgrade-for/HP-Compaq/hp-15-ay014tu
And the said webpage lists the following information:
Notes about your system:
Upgrades may need to be performed by an authorized service center.

Nontheless, the reference manual for my laptop model available on the HP's official website states otherwise:

The official reference manual of my laptop says it supports up to 12GB of memory (8GB + 4GB), but the crucial website states that up to 16GB of memory is supported..
Well... Obviously having only 12GB of memory installed will be safer, so I deem that part of the issue resolved.
Now, I already have ordered a 8GB RAM stick from the above Crucial webpage for my laptop model:
Crucial 8GB DDR3L-1600 SODIMM
CT9400088
DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 •
upgrade for HP - Compaq HP 15-ay014tu system.
The link for the above RAM part redirects to the following Crucial 'Where to Buy' webpage:
http://www.crucial.com/usa/en/wtb?ps-sku=CT102464BF160B
which refers to the Amazon item page for 'Crucial 8GB Single DDR3/DDR3L 1600 MT/S (PC3-12800) Unbuffered SODIMM 204-Pin Memory - CT102464BF160B at Amazon.com' I ordered from, last week.
The problem is, I don't know which of the following 4GB memory part models, listed on the above Crucial webpage for my laptop, is best for the other 4GB RAM stick I have yet to order:
Crucial 4GB DDR3L-1600 SODIMM
CT9400081
DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V •
upgrade for HP - Compaq HP 15-ay014tu system.(Whose 'Where to Buy' page is http://www.crucial.com/usa/en/wtb?ps-sku=CT51264BF160BJ)
Crucial 4GB DDR3L-1600 SODIMM
CT9400101
DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V •
upgrade for HP - Compaq HP 15-ay014tu system.(Whose 'Where to Buy' page is http://www.crucial.com/usa/en/wtb?ps-sku=CT51264BF160B)
They seem to have the same specs according to the above information, so my question is, what are their differences?
Namely,
1)Which one works best with the 8GB RAM stick I've already ordered?
2) (In case there's no difference between them as regards the above question 1),) which one is the superior model?
Best Regards.
