[quote="Regulus"]I'm not sure what problems you're referring to. In my previous computer, I had two 512MB sticks, and added in two 1GB sticks, for a total of 3GB without any issues.
Just a few days ago, I had two 2GB sticks, and I added in two 4GB sticks to my computer, for a total of 12GB. Once again, no problems. Just make sure the memory sticks are tested to work with your motherboard of choice.[/quote]
And you have enough ports. Many motherboards only have ports for two RAM sticks...
