How Can I Fix Non-Usable RAM?

Hi everyone,

I am a beginner in pc building so I don't know what is wrong when I have 12 gb of installed RAM but Windows 7 64bit shows only 1.99gb usable. I have looked around but I haven't come across any accurate or good advice or answers. one thing that i saw was that the cpu pins might be bent and that moving the pins back in place would fix it but i want to make sure before i do anything like that. If anyone will give me some advice or help I would appreciate it! Thanks!

Oh yeah my pc build is :
x58 mobo
i7 920 cpu
and i have 6 gb of gskill ram and 6 gb of corsair ram
the gskill ram is 1600 and corsair is 1333

  1. What does your bios say?

    it detects all of it in the bios
  3. Install CPU-Z, run it, click on SPD tab. What shows up there for each slot?

  6. Are you sure that you install the 64 bit version and not the 32 bit one?
