I got a huge increase in memory performance lapping the NB and still using the stock cooler! Managed to tighten the mem latency right up...

My North bridge's don't have the metal circle in them. They are all the black material. My old Abit KT7A had the metal circle though. Maybe it is a KT333-400 thing?
