So I have 64 Gb ram installed, I have tried every possible combination of RAM and ruled out the possibility of hardware. I had a new motherboard sent to me, and that did not fix it as well. All windows settings and systems show 48Gb installed. However a 3rd party software tells me I have 64Gb installed. Soo basically my 64Gb is installed and "working" but windows is not properly showing it. I am quite familiar with Tech, so all the basics -and advanced, ways to fix it have been tried. My motherboard supports well over 200Gb of Ram so thats not the problem, and 64Bit windows as well. I need some pro level help here. Thanks inj advanced.
