I would suggest you buy 2x2GB DDR2-533 (2 sticks of 2GB each).
Remove the existing RAM and replace it with the new memory in the existing slots.
This avoids compatibility problems between different RAM modules.
But I have already ordered a transcend 2GB DDR2 RAM which is running @ 800MHz... My friend told me that, 800MHz will get lowered to 533 MHz in order to work in tandem with my another chip...! So, what do I do? I can't cancel the order. My current RAM is "DYNET DDR2 800(5) 2GX16".
DDR2-800 will work if supported by your motherboard.
May or may not work with your existing RAM.
If you have already ordered it, you may as well try it.
If they don't work together initially, try old and new separately.
