4 slotsHow many ram slots do you have? Do all the modules work individually (one at a time)?
This document talks a little bit about the memory banking:I'm sorry for being a total noob how do I find this out
Install the memory by itself first to see if it is good. One step at a time.So what if I want to make the memory work at 1333
I'll try thisThere is a good chance that RAM won't work with your PC, it's a bit too high end. Take out the new RAM, check for a newer BIOS for the system and install it. Then install only the new RAM and see if it works. If not, get a stick of the same speed as the old RAM. You are better of replacing the existing 2gb stick with two 4gb sticks so they run in dual channel properly.
