Can you post up your BIOS settings for the DRAM and the systems voltages, might be QPI/VTT is low
As you requested, I have taken some photos of the BIOS settings that relate to the DRAM.
In one of the photos, you will see that the DRAM Frequency was set to AUTO (default) and in another, I had changed it to DDR3-1600MHz. I thought maybe that would help the OS recognize the RAM. No such luck.
This system is not overclocled - all of the settings are basically at default. Not because I am opposed to changing - I am just unsure what to change and how much.
Please forgive my newness here - I am not sure how to post photos directly to a thread, so I have uploaded them to an online gallery. Here is the link:http://postimg.org/gallery/6pjsjxz2/
