Vengeance ram difference serials?

[mbt9000]

Hello, my ram on my pc is corsair vengeance ddr4 16gb (2x8gb sticks) my serial is cm4x8gd3600c18k2d

The problem is I'm wanting to upgrade it to 32gb (2 more 8gb) and I've put the serial In amazon and Google and it shows my ram but with this serial - CMK16GX4M2Z3600C18

Does this matter? as I can't find the matching serial on amazon UK

You can just order two more sticks through your PCS account/upgrades?
Tends to be a competitive price and that way you shouldnt have teh same issues either.
