My 3770k at 4.5 pairs with 1866mhz ram and it requires 1.28v to be stable. When I use the 2400mhz ram kit, I have to increase the vcore to 1.3 coz it cant boot to window with 1.28v. Why?
I bought some 2400 and messed with it for about an hour and a half trying to get it to run.. I got it but my cpu did not like it, so I sold it for what I paid. With my cpu it doesn’t mind 2133 but at 2200 it starts getting cranky.
The motherboard quality matters quite a lot to get max speed.
I tried 2 motherboards before the one I now use, both mid/low end Z170 and neither board would let my 3000MHz ram run faster than 2500MHz.
It wasnt until I bought a mid/high end board it finally ran at 3000MHz and then overclocked like a beast.
