Upgrading the Ram and having a heat sink

[LedLoaf]

Hello,,

I just have 2 quick questions.

1. I have 32gbs and I want to upgrade to 64gbs. Do I buy two 16gbs for a total of 64gbs? 16GB DDR5-4800 SO-DIMM x 2

2. I have an SSD drive with a heatsink on it. SAMSUNG 980 PRO SSD with Heatsink 2TB
I'm hoping this will fit, and if not, is there any way to make it fit without buying another one? This is from my old MSI GT73VR 7RF laptop.

2a. How many SSD's can this thing hold?

Thanks

I guess I should give more details since I thought this forum was strictly for my laptop.

I have a ASUS ROG Strix Scar 16 (2023) Gaming Laptop. It supports all the above, but I haven't found information if a SSD WITH a heat-sink will fit or if it only takes ones without the heat-sink, similar to the ASUS ROG Maximus Z790 Hero motherboard I have for my desktop. Well, you could use it with the heat-sink, you would have to leave off the panel with the heating pads though, which I didn't want to do.

Lastly, I was told you have to use the same brand (or at least it would be better) of RAM. I have found no information on the brand of ram they use and I'm just going to assume that website did its research and it's the Crucial brand.

Thanks!

EDIT: I'm also trying to figure out if the laptop supports higher than 4800mhz for the RAM and if you can go up to 5600? It's based on the CPU, right? Therefore it should support 5600, being a 13th Gen Intel^® Core™ i9-13980HX Processor? I'm not sure if laptops are different though.

Can anyone help me on the follow up questions?

Thank you.
