I recently purchased a Dell XPS 8930 with i7 9700 and 16GB of installed RAM (2666mhz). Looks like it has Intel Z370 chipset.

I am a bit of a newbie, but assume this is 2x8gb installed by Dell?

I am looking to upgrade to at least 32gb ram. This is not a gaming rig, just require more ram for lotsa browser windows, large Excel sheets, and occasional audio/video editing.
I have found this: https://www.dell.com/community/XPS-Desktops/XPS-8930-Compatible-RAM/td-p/6093588

Are these really the only manufacturers with compatible RAM?

Would something like Corsair Vengeance LPX 2x8gb work to add into the other two slots? https://www.amazon.com/Corsair-Vengeance-3000MHz-Desktop-Memory/dp/B0134EW7G8/

Or should I replace the existing ram with 4x8gb?

Budget is +/- $150.
