Ram:
G.Skill - Trident Z Line-Up, Flare X, Sniper X, Performance(Budget Ram)
Klevv - ALL (Korean Brand)
TeamGroup - Delta RGB, Nighthawk RGB (not sure bout other models)
Corsair - Dominator (For standard Vengeance, do ensure that it is AMD compatible, NOT Intel compatible as they have 2 different set. If u purchase an Intel compatible, 40% chance for AMD system to work at stated speed); however for Vengeance RGB, may work on AMD as they don't have different set like their non rgb sibling
Adata - maybe all
Gigabyte - Majority of their SKUs uses Samsung B-Die (super expensive)
Patriot - not sure as not widely available in my country as there's no local distributor/supplier carry it
Kingston - maybe all (not 100% sure if the standard HyperX & Savage work for AMD or not. Their RGB line up do work)
Crucial - Never bother research as stocks not much readily available in my country
Geil - IDK (All I know their rams are kind of ugly for my own preference)
Might missed out some of the Brands as can't remember all of them.
