I have an Asus P5A socket 7 motherboard with 512kb of L2 cache on the motherboard. I'm considering installing more memory. Currently, I've got 64mb but want to upgrade to 128mb. I've heard that you can experience system slow downs if you install more memory than is cachable. What is the low down on this. I have a 300mhtz AMD k6-2 processor as my cpu on a 100mhtz motherboard.
