hello , i also had same problem. try swapping memories into different slots and make sure they are correctly connected.My all slots were functional,but after installation of new hyper 212 x CPU cooler, I found out that the last memory slot is not working rest 3 works fine.
Can someone help me with the issue?
Thanks.

What do you suggest unscrew completely and screw it again or just loosen it.Happens sometimes when you over-tighten the HSF. I would try not screwing it down so tight.
