Worked.
Ram is made up of silicon chiplets stuck to a pcb. All ram is, regardless of manufacturer or vendor. Those chiplets are punched out of a sheet and every sheet has different impurities and levels, no 2 sheets are the same, no 2 chiplets are identical.
So each stick is truly unique, responds differently, uses different amounts of voltage etc. It's those impurities that also change the 40 odd Secondary timings.
In the factory, they have access to thousands of sticks, all the same type, so can mix/match to find as many sticks as needed for a kit and compatibility.
But.
Asus tested one to 4 kits on that mobo, not hundreds of the same kits. That one test worked with 4x sticks. There's no guarantee that a different kit will work, only a high likelihood.
QVL is Quality Vendor List, not Quality Ram List. It only really says that Corsair ram worked without issue, Adata, Patriot, Samsung etc and that there were some issues with Crucial. Beyond that, isn't much difference, because even if you have ram on the list with a blue heatsink, the exact same ram might have nothing more than a red heatsink, but be a totally different serial number. The color of the heatsink is totally immaterial to how the ram works, but Asus tested the blue, so it's on the list, not the red.
Doesn't mean anything beyond 'We tested these, and they worked', you just have a good chance if using the same type (like Corsair LPX or Corsair Vengeance etc) that they'll work too.
