Corsiar Vengence 4GB x 4 only showing 1 avil.

Hello,

Recently purchased 4x4 Corsair cmz4gx3m1a1600c9 memory modules. When I first installed them they showed up with no problems. Recently I had to reset my BIOS settings for my Sabertooth 990fx and now only 1 module (4gb) is showing up. I have unplugged the memory modules and plugged them back in to no effect. When I update the bios to the latest version the system crashes and does not start. Any ideas?

Reset the CMOS memory the right way as is described in the motherboard manual using the clear CMOS link with the power cord unplugged.
And when the battery is out, press the power button to discharge all the electricity from the system.
