Windows 7: 16gigabytes installed only 3.95 usable

Windows 7 Ultimate x64 SP1

Did you try to actually load auto-RAM timings and check them against what they are supposed to be according to the manufacturer's specs? Do you have any overclocking software that would be changing RAM timings? Would they run ok if you downclock them?

Win 7 ultimate

Alright, I finally figured out the problem. I was using a corrupt RAM stick, with each new ram I got. Yep, a series of unfortunate luck. When I went to buy new ram, one stick was busted, when I returned it, and bought another, it came with yet another broken/non functioning stick. It took a lot of shopping and returning and the help of a pc tech to solve this. :\

Thanks for the help and suggestions guys! Wouldn't have gotten here otherwise.

I believe AddRam was referring to the ram not the mother board as to what product are you using.
