You do NOT want to waste your time with fancy Dual-Channel memory.
Get a 1 gigabyte, or maybe 1.5 gigabytes of regular memory thats apropriate to your system, and you are fine with EQ2.
The most important thing you can do is adjust your graphics settings. I have a pretty beefy PC (by 2002 standards), and I pull a good 20-40FPS (Frames per Second) in msot zones. In Freeport I drop to around 15-30FPS. Not great, but okay given the fact that there's not much action in Freeport.
Once you have a gig of ram, there's only 2 things to worry about performance-wise:
1) An ATI9700pro or GeForce 5900 series graphics card or better.
2) a 2.4ghz+ or 2500XP+ CPU or better.
Any of the AMD64 systems is more than enough. Any Intel 2.5ghz+ system is more than enough. Any AMD XP system (2500XP+) is more than enough.
The most important thing you can do is MAKE SURE YOUR GRAPHICS SETTINGS ARE APPROPRIATE. Consult the following thread at Everquest2.com for more details:

That thread has helped me more than anything else to get my EQ2 performance up to par. Prior to reading that thread, I was ready to quit the game due to bad performance. I am not a warez OverClocker boy who knows all the dirt on all the graphics cards & cpus. I do however know what ****** performance feels like, and with the help of the aforementioned thread I was able make EQ2 a smooth enjoyable experience on my 2 year old system.
