2GB @ 667MHz & 4GB @ 800MHz

[Iv00w]

I've had this setup for a while now, but I only just found out that right now, all of my memory is working at the lowest, which is 667 MHz.

Do you guys think that my performance would be higher if I removed the 2GB 667MHz?

2GB 667MHz & 4GB 800MHz OR 4GB 800MHz?

Thank you very much in advance!

If you are actually using all 6GB then your performance will decrease, but even if 4GB is enough you won't notice any difference.
