Hi,
I have the same card in my 1200. You only need one Crystal if your running them at the same speed (but you need to change a jumper). If I remember correctly, the manual for this card says "don't overclock the math chip, not even a little bit". I changed mine from 33 to 50 mHz, but I swaped the CPU and math chip to a 50mHz rated model.
