So I have ddr3 kingston 99u5474 4gb 1333 frequency but bios changes it into 1600, its set to automatic, should I change it back to 1333?
I'm currently running 1 ram slot, I have another 1333 different ram and when they are both plugged in it sets to 1333 in bios.
I also plan on buying another ram but there isnt another same ram only really similar to it with same voltages frequency and kingston maker.
