You set ram speed in bios.It needs to be at 166.
They should work well togetter,but you have to use the lower fsb speed.
further more the cas latencies need to be set at the slowest timings from the slowest stick.
So if the pc3200 is cas 2,5 ,3,3,7 for instance and the other is cas 3,3,3,6 you have to use the slowest for each and end up with cas 3,3,3,7 for both.
Ram will run at slower timings regardless,but not always at higher then it's sold for so experiment with that when things are stable.
Find the settings for your mainboard on the internet so you know which ones to change .
Goodluck...

ps. use cpuz for a good representation of your memory and cpu etc.
