Bought this rig about 3-4 months ago and I think it's about time for an upgrade. But I am not too good with pcs when it comes to ram so any help on what ram i can use with the ram that is already in the pc would be great just trying to add another 8gbs on top of what i already have pc link below-v

B250 Chipset motherboard has four slots for DDR4-2400MHz memory. Adding memory is not recommended as the old memory has never been tested with new memory. No guarantee that adding extra memory will work or how it will work if it does.

If you want to go that route and add extra memory you are free to do your own compatibility testing.

So, I need to replace the ram not add onto it?
