Question Does it absolutely matter which Corsair Vengeance kit I pick out if I want to upgrade size?

I currently have a 2x8GB kit @ 3200MHz C16 kit with the following SKU: CMK16GX4M2D3200C16
My plan is to add an additional 16GB of RAM to my system but unfortunately I can no longer find an identical kit in stock (at least in my country). The only one in stock is the kit with this SKU: CMK16GX4M2E3200C16.
As far as I could find their specifications are 1:1 but I'm worried about any issues I could get by mixing two different kits. Has anyone tried them before? Would I have to manually redo the timings or am I better off getting a brand new kit altogether?

Mixing two kits, even identical ones, is not guaranteed to work. There is always some chance for various problems, from not being able to run at advertised speeds even up to the system not working at all. If you want safe option then you should sell your 2x8 kit and buy 2x16 one.

they says it is the new model but mixing ram could or could not work it is a trial and error .

Hit and Miss. You won't know till you try all of them together.
