I have an Asus P9X79-E-WS, 3930k and 4gb of some old ram that i found I wanted to test the board and the new components to see what I would be working with but my problem is that the board doesn't read 4gb of ram it reads 3gb in bios and windows. However the cpuz shows that I'm running quad channel and 4gb or ram and it detects the ram so is the ram or could it be the board?
 
Solution
May be due to a 32bit OS which normally can only run up to about 3.5GB, or if on a 64bit OS, may simply be you have too much system overhead on the X79 mobo, especially since your only running 4 1GB sticks if it shows you in quad channel

What OS are you running, Is it 32 or 64-bit?

Windows8 64x Bios reads 3 Windows reads 3 But CPUZ reads 4gb and quad channel. another thing is when i remove all the other slots in bios it shows them being removed except for this one slot. which is the 3rd blue slot. forgot to put ram specs DDR3 XMS3-1600 1.80V 4x1GB

Looks like just system overhead, regardless I'd really suggest changing sticks, 1.8 voltage is to high, when this came out about 1.65 was considered high (1.5 the norm), and the 1.65 back then was suggest for sticks 1600 and higher. I'd look for at worse a 2x4GB set and preferably 4X2GB so you can get the performance gain of the quad channel controller, in a 1600 or 1866 set of sticks (1.5)
