How to return 8 gb of ram?

Question

Computers

Hello everyone, I began to notice a hang in the PC. I decided to check the properties of the PC and it began to be displayed instead of 16GB, it became 8 GB. The RAM is a year old, like the rest of the PC. Device manager shows only 1 plate. What to do?

Answer 1

You open it, see how many there are physically. If there is one, then they have been skomunizdili.
If there are two of them, then:
Pull out both and check the volume on the sticker
Blow out the dust in the slot and wipe the contacts with a soft eraser on the bar itself
Insert one at a time and check the operation of the computer
After finding the dead one, wipe everything again, double-check and go to the store for a new one
