If your memory isn't completly identical could it still run in dual channel but with problems?
My system isn't stable and I think this might be the problem but I figured I would ask before running a million tests.
Well I found out the answer and its YES. Your computer will run dual channel even if their not matched but mine caused problems. I gather this because I ran dual channel and it worked but recently it started acting weird. Now I have them not in dual channel and everything works perfect.
