Hi,

I know it's a simple and often asked question but all the similar topics I've found on the internet keep derailing into topics about mixing voltages or speeds.

I have 2x2GB ram installed in dual channel right now.
If I buy the exact same stick of ram from the store, just a bigger 2x4GB size and installt in the 2 free DIMM slots, should it run fine?

Or should i only match 2x2 with 2x2?

Even another set of 2x2GB of the same exact model can be and often is problematic. It's harder for manufacturers to find 4 sticks that all play nice together, which is why a 4 stick set typically is more expensive than a 2 stick set, it's from the testing to make a set. If DRAM was as easy to mix as many would have you believe the manufacturers would simply sell 1 stick packages and let people buy as many sticks as they want/need.

Thank you a lot for the info!
I'm from Norway and we can return a product within 14 days of purchase, regardless of reason, even if you've used it.
I guess I'll buy a pair and test them, if they don't work well I'll return them.
