My Ispirion has the default 3gb RAM, but that doesn't cut it anymore, and that's why I decided to upgrade it. But I don't know which is the limit of ram that I can buy, some websites say that the maximum is 6GB and others say its 8 GB. And also what should they say in terms of 2x2 or 2x4. Sorry, but I'm new in the RAM upgrading ambit. If I'm forgetting to add some specs, please tell me and I post them. Thanks!
