Hey Guys, so I have two RAMs of corsair, one 1333Mhz and other 1600 Mhz. I was using them for quite some time. Then I didn't use my PC at all for about a year. So funny thing is now my bios shows only one ram. Individually installed it shows both of them, but when I put both the sticks together. Only one is shown in bios. I'm confused?!
