RE: Does Dell Technical Support Know Anything About Their Computers?
Well the seems no one has definitively answered your question about whether or not dual channel is supported. But if you are concerned about system performance then the answer does not matter that much. Based on two studies I found by Googling "single vs dual channel ram" the conclusion was that there was no significant performance gain between single and dual channel. I would also say you a fortunate that you have 8 GB in a single memory stick, that means you can expand to 16 GB by purchasing another stick instead of being stuck with two useless 4 GB sticks.
