[SOLVED] SSD & Compatible RAM..?

[ArmadaCas]

Good morning guys.

A couple of quick questions:
I currently have 16GB (2x8GB sticks) of Viper Patriot RAM in my ASUS Z170 Pro Gaming/i7 6700k system (as shown here).
https://www.amazon.co.uk/dp/B0157UQ...olid=3U7C7X0WQMAU3&psc=0&ref_=lv_ov_lig_dp_it
If I want to upgrade, do I need the same set of RAM again, or can I use a different brand such as Corsair Vengeance, as long as it's 2x8GB at 3000MHz..? Also, could I instead add 2x16GB of Viper Patriot as long as it's the same brand and at 3000MHz..? I'd probably much rather add the 2x16GB, so hopefully that's possible. At the moment I can have 2x16GB Viper Patriot at 3000MHz for €199, whereas 2x8GB of Corsair Dominator Platinum is around €160-€170.

Last question. As above,:

and
https://www.amazon.it/dp/B07MBQPQ62...olid=3U7C7X0WQMAU3&psc=1&ref_=lv_ov_lig_dp_it
As can be seen the 2x16GB of RAM is currently €199 and the 1TB Samsung 970 EVO Plus is €236.
Should I buy both now, or wait because they'll become cheaper still sometime later..?

Thanks for your time, guys.

2x16GB option would be a better choice.
With 2x8GB + 2x8GB it's possible to run into ram compatibility issues (mixture of different ram kits).
Also with 4 ram modules on dual channel board you get slight performance penalty.
