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.
The vast majority of games work just fine with 16gb RAM. I recommend running your higher speed modules as dual-channel and selling/repurposing your previous hardware.
Unless they are the same brand and specification, patchwork RAM tends to have compatibility issues leading to software hanging and potential crashes. YMMV.
This… also, use your motherboards QVL when selecting your new kit.
