Can you help? Questions in comments.

So I got these two stick in my lenovo c365 (all in one)

The computer come with bottom ram stick

So I order a copy so I could have 8gb but a different stick arrived.

I've checked bios and says it's running at 8gb 1600mhz

Checked computer properties says 8gb

It's running fine but I'm not sure if I down the right thing.

So I have a few questions...

• they both start with M471B5173 but the last 3 letters/numbers are different does that matter can I still use them together?

• One says 11-12-B4 but other as 13. What's that mean and does difference matter

• G2 logo on one but not other what's does that mean/do

• QR code and numbers are different on each what does that mean/do?

• Does it matter what stick goes in each ram slot?
