So I have a msi z87 motherboard and my ram when I bought it said 1866mhz, but when I check how fast its working it says 1333mhz, how do I make it go up to 1866mhz? Thank you
go into the bios and go OC.
if you go down a little there should be ram speed and ram base speed.
just click on ram speed and go to the frequency you want.
I will make a video tonight if you need any more help.
ps you can go further than 1866 I have mine set to 2400Mhz
