I've read in the past (can't find it right now) that going from memory in two dimms to three causes increased latency, and therefore slower memory performance. I have a Abit BE6-II BX MB, and have two 128M modules, one in slot 1, and one in slot 2. With the memory prices so low now, I'm tempted to get another 128M stick. Can anyone confirm that there actually is a memory performance hit when filling all three dimm slots?
