I have a 4 memory slot motherboard that will run duel channel, but only 3 slots work. I currently have two 2gb sticks in duel channel slots. The system is x64 and can handle up to 16gb. My question is will I get an improvement in performance if I put a 4gb stick in the 3rd working slot but loose duel channel memory use? I play online games and am starting to lower my settings to get less lag. Thank you!

I fairly sure its the motherboard that is broke. Slot 1 is the issue, at one point i had my existing memory in 1 and 2 and noticed that things were slow after about a year of use. Only one stick was recognized so after some trial i found the problem. The motherboard is about 3 years old.

If I do add a third stick increasing the memory and loosing duel channel would i have an increase of performance or decrease?

Thank you for the comments!
