I have two kingston 8gb RAM sticks in my PC. it has always worked, for 6 years straight. Out of nowhere i have 8gb RAM according to the following: Windows info, BIOS, CaniRunit. But Speccy tells me i have two 8gb installed, but 8 available physical ram (as seen below). I took out both sticks one by one and put them in the other while rebooting. Both sticks are fully operational, and so are both slots.

I tried to clear the CMOS, don't know if it worked. (i dont have a jumper so i used a paperclip)
This problem is out of the blue, i don't know what caused it. This might as well have been going on for weeks, i dont game all that often anymore so i didn't really notice anything wrong until i saw it in task manager.

if anyone knows a solution or something to try, PLEASE do say. I'm out of ideas.
