requirments for jpcsp for full speed

[LeaT]

I am curious to hear what you would say would be good RAM speed for JPCSP, or is the model type more important i.e. DDR3 over DDR2? I am running both and this is the only part I haven't actually changed in my hardware and I experience the same speed as I did before upgrading my system.

I just like the fact I don't have to squeeze my eyes when I run on the PC.
