How to set up the RAM

GODFallout15

So I bought an ASPIRE A715-72G-53F4, and it says the next:

• 20GB Memory, 16GB Intel Optaine Memory + 4GB DDR4 Memory

So my question is: ¿Is this the RAM or what is it?, ¿How can I set it up?

I'm still new and pretty dumb for this area. Thank you for your attention and help.

You have 4GB of ordinary DDR4 RAM. The 16GB optane memory is NOT ordinary DDR4 RAM. It is only acting as a memory cache on a separate card to help speed up your mechanical hard drive. There is nothing for you to do as it's already set up in the BIOS. If you ever change the mechanical HDD to a solid state drive SSD, the optane memory will no longer be used or needed.  Jack E/NJ
