i have 16 gb (2x8) of corsair ddr4 vengeance lpx ram, but windows says that only 7.95 gb of that are usable. i have tried clearing cmos, reseating ram, changing voltage for ram and processor, changing ram timing, and changing speed on both the ram and processor. all of those just crash the computer, causing it to go back to default values. at this point, i've just given up.
