Missing 2GB RAM

[Cwai]

Hi.

Problem: Bios only detected 4GB RAM.

Please find my below system specifications:

Model of the motherboard: Asus P6X58D-E
Model of the memory : G.Skill F3-12800CL7T-6GBPI (Plan to upgrade to 12GB)
Model of the CPU : I7 960
Storage : OCZ SATA 2 2.5 " SSD
VGA : Nvidia GTX460. (Planning for SLI)

Problem: Bios only detected 4GB RAM.
I have read through the "Missing capacity? 6GB detecting 4GB in BIOS? 4GB only showing 2GB? Read this."
However I'm a newbie in this matter. Please advice me the settings.
Thanks in advance.

Send the memory in for new replacements. The new set should work better.
