Specs First:
Mainboard : Asus P6T
Processor : Intel Core i7 920 @ 2666 MHz
Physical Memory : 6144 MB (3 x 2048 DDR3-SDRAM )
Video Card : NVIDIA GeForce GTX 275
Hard Disk : WDC (640 GB)
Operating System : Windows 7 Ultimate Professional 6.01.7100 (x64)

Ok so CPU-Z says I am running Dual Memory with 4 gigs, but it recognizes all three of my memory slots that are occupied trying to get tipple memory for 6 gigs. Windows 7 64bit also says I have 4 gigs of memory.

THis is what PC wizard says...

DIMM1 : Empty
DIMM2 : Empty (HERE IS MY OTHER DIMM SAME AS THE OTHER TWO)
DIMM3 : Empty
DIMM4 (RAS 5) : 2048 (Single Bank)
DIMM5 : Empty

SO I am confused. CPU-Z and PC Wizard both show the memory in DIMM slot 2, but does not use it...

Any suggestions?

Try reseating the stick. If that doesn't work maybe it's a bad stick. Swap them around to see if it works in another DIMM.
