Stupid RAM upgrade question

[Swarrly]

Hi guys. I am super to this forum and computer building in general so i'm sorry if this is a dumb question. 

 

Currently i have only 4GB of ram in my machine and I'd like to upgrade it. 

 

This is what I'm currently running

I'd like to get up to at least 8GB. I have room for another 2 sticks on my motherboard. If I buy two 4GB sticks could I just put it in along side my old ram or should i just replace it completely?

 

I was thinking of buying this

thinking I could always replace the old ram later if i end up needing 16GB

 

Would that ram work?

 

Thank you for your help.

That should work. 

 

You can buy a single 8GB module and buy another in the future to get 16GB but you will lose the benefit of dual channel until you upgrade.

Just get an 8gb stick so you can upgrade higher later

Effectively doubles the memory speed by making both modules work together. 

 

However, it usually helps in few tasks in practice (usually speeds up APUs).
