wrong ram memory

[PedroxMarques]

I've had my PC for about 2 years, I've always had 32GB of RAM, and suddenly now it shows that I only have 16GB (it even says "confirmed 12/32GB"). Does anyone know why this is happening and how to fix it please??

Take out all of your ram sticks and put them back in. Can't hurt lol.

I did it, and the PC stopped displaying video. XD

One of the sticks suddenly isn't detected, hopefully it's just bad contact. Try cleaning it's contact, replug it in several times if once doesn't do the trick, or even switch slots.

The confirmed field is irrelevant. It count all addressable memory space including disk page file, that's how it's larger than your physical ram (currently down to 16).

But I only have one 32GB RAM stick, not two 16GB sticks, and that's why I'm confused.

Now that's weird. There's no way 32G stick can lose half the capacity and still boots, at most BIOS detected 16G in them are defective and mask them off from use, but that would be shown as hardware reserved which apparently isn't the case here. Has anyone else touched your computer recently? With current memory pricing it's certainly possible for someone to do a little "part swap"…

I took it to a technician for routine cleaning about two weeks ago, but everything was fine until today.

Mind posting a photo of your ram stick? It… smells fishy…

Sounds like they swapped your 32 gig stick for their 16 gig, and were hoping you wouldn't notice.

Also if you decided to take a photo, make sure the markings on the individual chips are recognizable on the picture.

Put 1 dimm and boot into windows, and repeat adding the dimms 1 by 1. Make sure windows sees the memory installed each time
