HP Notebook - 15-da0032wm RAM Upgrade: 8GB or 12GB?

[Rcooley13]

Hi there. I bought this laptop and it comes standard with 4GB RAM. 

I bought the following: 

A-Tech 8GB DDR4 2400 MHz SODIMM 260-Pin PC4-19200 1Rx8 1.2V CL17 Notebook Laptop RAM Computer Memory Upgrade Module

 I was originally planning on installing just the new 8 GB by itself. However I realize that my wife's HP Omen gaming laptop has 1 x 8GB and 1 x 4GB for a total of 12GB (came that way from HP). 

Would I be able to use the 8GB with the 4GB that the laptop currently has and have 12 gigabytes as well?

If so which one should go in which slot?

And ultimately will I see much of a difference between the 4GB and 12gb?

Thanks!

Hi:

Yes you can do that, and it doesn't matter which slot you put the memory in.

You will have 8 more GB of memory, but it won't run in the higher performing dual data rate (DDR) mode since the memory is in mismatched capacities.  It should give you more performance than you are getting now.

In order for the memory to run in DDR mode the memory has to be installed in matched capacities (2 x 4 GB, 2 x 8 GB).

Would I see more performance, 12GB as opposed to 8GB?

If not...why did HP put 8&4 in my wife's gaming rig? Is it really not 12gb?

Yes, you will.

Why HP installed 8 + 4 in your wife's laptop is beyond me.

They should have put 2 x 8 GB in there so the memory ran in the better performing DDR mode.

Watch this video.  The same applies when you don't have the same capacity memory in both slots...
