Ultra 4 + 4 gig

Yup. It's reducing the usage of the swap-file that is what motivates me at this time. Also, some other issues that I know are related to memory usage (not stability related) that are prompting me to do the upgrade. Smoothing out of performance is the goal here. When i originally put the 2GB stick in, i didn't have many add-ons running concurrently. That's no longer the case. I Know CIFS will cache up most of the memory for transfers. Like I say, the lack of free memory isn't what's bothering me, it's the ever-increasing swapfile size.
