I Need A Suggestion About Ram Or A Video Card!

[Chase00]

So only PC2100 RAM will work, PC3200 won't work?

Yes, that is correct. The other RAM sticks in your PC are also PC2100 modules. IF you mismatch them, it will be dead in the water. I'm sure you can use a higher speed RAM, but it's no use. It won't go at that speed because your motherboard is the limiting factor.
