The more memory you have, the more stress you put your CPU, motherboard, Memory controller, and system as a whole under. DDR5 at capacities of 32GB sticks or higher are all Duel Chanel, meaning each ram chip uses 2 channels of data flow with your cpu and memory controller. With ram, 2 sticks is ALWAYS > than 4 sticks and basically only going going to work with XMP, especially at high speeds....ram is all sold is in those packs of two because they all the chips were tested by the companies, and they then paired together all the chips that performed the same, so they woul dbe more stable.....then they also make sure they will run as whatever transfer speeds and timings they decide they are comfortable guarenteeing people will be able to use. There is no such thing as "running xmp with 4 sticks" because an XMP profile is the profile specified by the ram chip makers for those 2 SPECIFIC memory chips in that package and those 2 chips alone. So, when they were tested, and they wre able to get 2 32gb sticks to run at 7000mt/s and are confident anyone who buys them will be able to too, they put their stamp of apporval on it. But imagine motherboard/cpu/memory controller are all connected by a highway....each chip is 2 channels since as i mentioned 32gb or higher is all 2 channels per chip. so your 2 chips are taking up thje space of 4 cars on that highway already, if you put 2 more chips in there, even if they are rated for the same speed, you are adding 4 more cars to that highway, making itharder for traffic to get through, creating ALOT more data that needs to be sent through....more chips also means more voltage needs to make it way through the controller and through the chips, and to the cpu....more voltage is more heat, more heat is less stability....you see where this going. Chips are sold that way for a reason, and no where is it marketed or recommended to use 4 sticks of memory, at least if you are going to high speeds and want the be sure to achieve the rated xmp speeds. Its why 4 slot motherboards have favored slots they recommend you use when install just 2 Chips. Dont be afraid to ask questions about stuff, people will help. ALL ram manufacturers post their ram kits ont heir websites with a list what kits they gaurentee will run xmp on what boards....you can go to gskill's page, search for your motherboard, and it will show you exactly what they say will work, and it'll all be 2 chip kits....4 chip kits dont exist. Now if you are running just Jdec standard spec, and you do ALOT of digital design work and graphics rendering, go to town with 4 chips, at jdecc specc they will work jsut fine. If you are just gaming, first of att, you dont need and wont need more than 32GB total, 64gb if you really wanna be safe, for YEARS to come, if ever.....i have 64 and play very taxing games, and have never seen my computer use more than 10GB at a time. Also, with DDR5 and gaming these days....you would never be able tot ell if you were playing a game with 4 chips running 4400 mt/s or 4 chips running 8000mt/s. jdecc spec kits are performing less than 5 percent slower than high speed xmp kits in most benchmarks and modern games, especially so when playing at 1440p or higher, which is what more people are playing at now what basically all affordable displays makes are even using now as their base resolution now. Stuff is GPU bottlenecked most of the time gaming now, ram plays very little roll in the gaming performance now, unless you have unsupported memory installs, too much, or just bad settings....then you'll just be busy rebooting your PC after BSOD after BSOD lol
