I am going to upgrade my 8gb desktop pc. I have 2 free slots and 2 slots with 2x4gb 2400Mhz. I will buy 2x8gb with 3600 MHz. Should I put them together and have 24gb at 2400Mhz or should I remove the 2x4 in favor of the 3600Mhz.

I’m asking because I read that when you have 2 different ram speeds it will default to the lower one.

Edit: it’s for gaming and I have a Ryzen 3 1200 with a b350m as a motherboard

    Ryzens, especially earlier gen are quite picky when it comes to using 4 RAM modules. Sometimes even RAM that seems to work in 4-module configuration causes memory errors, even if every module is good. I had a case like that where I was running 4x Corsair from QVL on an 1800X. The QVL only listed this RAM in a 2x configuration. Running it in 2x would produce no errors. Running it in 4x would produce errors. Whatever you decide to do, make sure you test it using Memtest86+ for 3-4 passes. In my case the errors would only show in the 2-4 pass. The first pass is a shorter and lighter one which allows for catching obviously defective RAM quickly.
