RAM upgrade

[nab45353]

I currently have 4 GB DDR4 2133 MHZ

would u recommend me buying a 8 GB ram 2400 MHZ and removing my 4 GB RAM

or would u recommend buying 2400 MHZ DDR4 GB ram adding to my 4 GB 2133 mhz ram

which would boost the performance the best as im unable to find 2133 MHZ  ram

im also thinking to buy SSD and replace my Hard drive...but what would be the 1st upgrade i should do?

Hi:

It's hard to say which upgrade I would do first.

If I had to make a choice, I would replace the hard drive with a SSD first.

That will really provide a decent performance boost.

Memory...

You can either add the 8 GB module to the 4 GB module and have 12 GB of memory running in the lower performing single channel mode, or add another 4 GB module to the existing 4 GB module and have 8 GB memory running in the higher performing dual channel mode.

Right now the single 4 GB memory chip is running in the lower performing single channel mode.

Which is better?  I would go with the 12 GB of memory and someday, remove the 4 GB chip and replace it with an 8 GB chip so that you have 16 GB of memory running in dual channel mode.

Below is the link to the service manual...
