IM BEGGING FOR HELP with FPS & RAM!

hey all, i currently have a pretty decent computer setup -
AMD Ahtlon XP 2600
512 RAM (have to check out waht exactly)
80 GB Harddrive
Nividia FX5200
FS9 runs well, EXCEPT FOR CLOUDS!!!!!!!!!!!!!!!
as soon as i hit clouds, thick ones in the sky, my FPS drop from about 17-22, to about 7-8, its appualing!
now then, i know im recycling old topics, but i just want one helpful reply! PLEASE!
i have a Soltek Motherboard that supports DDR400 ram, i want to know, if upgrading to a GB of ram (an extra 512 strip) would give me just a few extra FPS, to run smoother and also, what ram would be best, and most suitable for my setup!
please help!
