Predator PO5-600s add ram what type of ram can i have and if possible

hi, new to upgrades and got few questions.
I got Predator PO5-600s with 16gb ram (DDR4 2666)
Planning to change them to 2x16gb / or add ( depends if that's ok to have two different size rams running at same time. PS: i know that high value ram must be in first slot)

One more thing, i know some of ram have cooling case on them , On my PC I'm quit limited with space so don't need all the RGB and just minimum case or to none.
So, the main question, what type of ram can i have and if possible with full name so i can search in big shops/online.

Ask if need more details.

[Edited the thread to add model name to the title]

Not for RAM modules, heatsinks are more for SSDs.

If you want maximum recommended RAM (32GB) you should use all 4 slots 4x8GB (see table above) that will run in Dual Channel Mode. https://www.crucial.in/memory/ddr4/ct2k8g4dfs824a/ct15616510 Buy 2 kits (2x8GB/kit) with identical specs, if you mix the modules it may run in Single Channel Mode.
