Question about adding more ram

Hello everyone this is my first time here and my question is about my motherboard.First it's max ram it can take is 4gig and i have 4 slots and i have currently three one gig sticks on it.Now i know that each stick is 1024 total for 3068 so if i add another 1024 that=4072.So my question is if i go over my 4 gig limit does it hurt my motherboard or so it not matter?Because i plan on getting another stick.EDIT and the ram is ddr2 533mhz

Welcome, Newcomer. To answer your question, no, you won't harm your motherboard. The max support (recognition) is 4GB. This means that anything above the limit will not be recognized.

Be aware that occupying all DIMM slots on your motherboard may require you to increase your DRAM Voltage by about .1 V. This is done in the BIOS. Also if you're going to add another stick, it would be best if you installed identical DIMMs to reduce the risk of instability.

I have windows XP SP3 and its 32 bit so ur saying i cant have over 3.25gb?

my system wont read over 3gb with 4 sticks of dual channel ram 1 gb ram in it.So yea i just need to upgrade my OS when i get the extra cash...but i have to say that between vista and windows 7 i dunno what to get EDIT and my system is windows xp 32bit
