“Acer says "This model supports DDR4 2666/3200 SODIMM." The Best Buy specifications show the memory speed as DDR4 2933mhz. What type of memory should I buy to match the existing 8gb? Has anyone upgraded their memory and what did you buy?”

I just bought this laptop (model AN515-55-53AG) because the description stated max of 32GB and it already has 8GB of 2933MHz installed. Great. I also checked the RAM via Task Manager and it says it has 8GB of 2933MHz RAM installed. Great. Now I want to pull that 8GB out and install two 16GB 2933GHz RAM sticks inside (32GB max) but hold up... Before we do that, lets check how much RAM this laptop can use. You can check this by opening up cmd and typing in "wmic memphysical get MaxCapacity, MemoryDevices"... what?! only 8388608KB of max RAM can be used for this device? (8388608 / 1048576 = 8GB). So what's the deal here? The BestBuy description says max of 32GB RAM and its coming with 8GB of 2933MHz RAM. But the Acer folks on here says it can only support 2600/3200MHz RAM. And both BestBuy and Acer are saying this model (AN515-55-53AG) has a max of 32GB of RAM. But the computer itself just showed me that the max it can use is 8GB... So is this a BIOS issue? Or an Acer limitation? I know the 10th Gen i5 can handle at least 64GB of RAM as I also bought another laptop with the same processor (by ASUS) and it's showing me it can handle 64GB of RAM (with only 8GB RAM currently installed). I'd like to know more about this before I return this laptop back to BestBuy.
Sorry, there was a problem. Please try again later.If your cpu is a 10th generation i5, (mine is an i5-10300h) then your cou memory bus speed is 2933. Crucial's 3200mHz ram came stock in Nitro 515-55-53. I replaced the 8gb stick with a pair of same spec crucial 16gb memory sticks. Nice boost in performance. The 3200 speed memory automaically adjusts down to the clu bus speed. The 2666 speed will stay at 2666mHz. The nitro's mobo will not allow overclocking. If you want every ounce of dram performance buy the 3200. If you want to save a few bucks get the 2666. The crucial is recommended and works well and is stable. No crashes.
Sorry, there was a problem. Please try again later.I wish someone answered your question. Im confused as well. The specs on the website say one speed of ram comes with this but the posts all say two other speeds. I dont want to open mine up until I know for sure and have the memory in hand to upgrade. I also don't understand if its dual channel or not. One person asked if the second stick had to match the original 8g stick and the answer was it doesnt have to it will run fine either way. That doesn't answer the question. If its duel channel it would run far better with equal sticks and just run somewhat better with just adding a large one. Is it dual channel or not and why do the specs say on memory speed but the posts say otherwise.
