if its a p3 then Im pretty sure it'll support more than what you're trying to put, So the problem is either with the tsick you got, or something to do with your mobo, or CPU something liek that
and a good and easy way to find out what your motherboard is, is to run programs like sisoft sandra which can be found Here
basically you just do a computer scan, If I remember it correctly and you will be shown your entire hardware setup including GFX card, RAM type and amount, Mobo, Processor etc.. And from there you can figure out the specs of your mobo
My deepest and best guess though is that theres something faulty with one of the sticks
