I have just built my new system got it all running and i noticed not all my ram is registering. i have 4x4gig kingston 2400 ram modules and windows only sees 12 gigs. Ive tried reseating the cpu and ram. testing individually they work fine,there's no bent pins on my socket. I tried mem test and it only sees only 12 gigs and tests fine. If i look in cpuz it sees 16 gigs even 3d mark sees 16 gigs and all 4 dims post fine in bios. Does anyone have anymore ideas for me to try PLEASE HELP its driving me crazy im starting to think its the mobo.
