AMD Ryzen 7 3750H different memory modules

[juliobozek]

Hi everyone. I have a ASUS FX505DT laptop which came with 8gb 2666mhz ram. The cpu is AMD Ryzen 3750H. I bought one more memory module, 8gb 2400mhz. Every module is in its own channel. Sometimes i see very minor sound shutters while browsing web or similar. Is this due to different ram speeds? In theory, it shouldn't be a problem cuz max memory speed defined by AMD is 2400mhz and the 2666mhz module should run slower. I attached CPU-Z ram details. Thank you for your response. Sorry, my english isn't perfect :)
