RAM upgrade, same model?

[Devmarta]

Hi all, I built my PC in 2014 with 1x stick of 8GB RAM with the idea that if I need more later I can add another stick of the same when I need it. Judging by my high RAM usage percentage recently in games I'm think it's time to upgrade to 16GB.

Can I just by another stick of 8GB and chuck it in with the old one? Does it have to be the same brand/model etc? 

The kit I bought in 2014 is Kingtson 8GB KTH9600C/8G DDR3 SDRAM KTH9600C/8G and I believe it may now be discontinued. Do I need to get another stick of the exact same to run along with my old one, or should I buy whatever is newer which seems to be Kingston 8GB DDR3 PC3-12800 1600MHz Single Rank Memory KTD-PE316S/8G? Will they run together? The latter appears to be AU$139 rather than the former which is AU$79.

 

Any advice would be much appreciated

James

As long as they are the same speed, type, and what not they should work. I've tried literally every different combination of DDR2 and everything worked. Just take a look at the LifeHacker article.
