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.

If the BIOS isn't seeing it, Windows won't either.

I noticed they are running in single channel ( Channels # Single ). I'm not familiar with speccy, but RAM usually runs in dual channel mode. Which would lead me to believe the sticks in the wrong slots. The motherboard User Manual should cover which slots are to be used when two sticks are being used.

As for the BIOS, aside from the jumper, you can simply enter the BIOS and choose "Restore to factory default", save, and exit. After the reboot, reenter the BIOS and ensure all of your settings are correct.

You could also power off, remove AC power, and try removing and reinserting both RAM sticks (or even swapping positions).
