ok- I assume you mean a 128 MB chip...? or could it be a 256 mb chip..?

There isn't a 156 that I am aware of.... Either way, yes you should add memory- It's cost effective and you would see a boost in performance.

Pionex is just an intel clone, put together in Denver-I was a dealer for them at one time. They will use standard memory and it would be pretty cheap. You'd probably spend about 10 -20 bucks for a decent memory upgrade from ebay.

My opinion: Throw out the 64mb and populate the two empty slots with matching 128 mb chips giving you a total of 384. That should run lots better than the 192 you currently have and should only cost about $25.
