If i use much faster ram than cpu supports will motherboard automatically adjust it?

[ninjaboyxd629]

im planning to buy a ryzen 5 1500x and MSI A320M-A Pro the mobo supports up to 3200 oc ram or 2666 but not oced im planning to buy a 2x8gb 3200mhz ram and it says on the mobo it supports it but the cpu only supports 2666mhz ram and ive done a lot of research and i found on a forum that the mobo will automatically adjust the ram speed in order for it to be compatible with the cpu and work is it true or i just have to find and buy a 2666mhz ram?

i belive it is as you say, if your mother board doesn't support 3200, then it will just run it at 2666 that it supports

do i have to underclock it in bios or the mobo will automatically adjust it to 2666?

not quite sure, but i imagine if it tries to run at 3200 then the motherboard will just either cap the ram at 2666, if it turns out that it doesn't automatically cap it at 2666 and your system crashes, then you can try to manually set it to 2666 in your bios (though i don't think that would be necessary)

im gonna change the question pls answer if you know 

is a 3200mhz ram going to work with a ryzen 5 1500x because it only supports upto 2400mhz or not? the motherboard will definitly support it but the cpu.. idk

if the cpu only supports 2400 then no it won't be able to run at 3200, but it will be able to run at up to 2400

so it will work but the ram will only run at 2400 not 3200 right?

According to AMD specs the 1500X supports "officially" memory speeds up to only 2667MHz. 

 

However many users on other forums have reported being able to run up to 3600MHz memory with others saying 3200MHz is attainable without issues on boards with AGESA  1.0.0.4 on both B350 and B450 chipsets if they manually set the frequency and dial in the timings. Unfortunately there was no mention of A320. So to answer your question, if you buy memory that is rated for more than 2667MHz, there is a good chance that the board will automatically underclock the RAM to meet specifications. That being said, "unofficially" you could possibly be able to overclock your memory (run it as pre-binned) if you have a supporting board (again not sure if this will work on A320 as well). 

 

Just fyi, while your particular mileage may vary depending on the exact memory that you get, most memory kits that are JEDEC 2400MHz or 2666MHz can overclock to 3200MHz if you loosen up the timings a bit. Therefore, I would advise not to overpay for RAM that might not work at the rated speed.
