Hello , I was looking to buy a new atx gaming mother board under or around 150£ . And I was wondering if there’s any good mother board you guys can suggest and if there’s anything else important in a motherboard then it’s size , ddr , intel/amd comparability, and so on . And I was wondering for ram , if I can stack 2 different rams at onec for example if I have a 8 and a 4gb stick do I get 12gb’s? Or is it only 8? And are rams from different producers compatible?
