i am upgrading my memory and will i notice any differernce if i chose ddr2 400 or ddr2 533 mhz i use my computer moslty for gaming and i am upgrading from 512 to get 2 gigs more
 
It depends on your motherboard, if it can only use up to 400mHz speeds, than no... If it can use 533mHz, than yes... You should be able to find out in your BIOS exactly what speed of RAM your mobo can take...

it can go up to 533 mhz but will i notice any differnce at all
 
what board and cpu are we talking about here.
Yes the board may handle ram faster than ddr400 but what if your cpu runs off of 200fsb. Unless your board permits you to run you ram async and faster than your cpu then you could be wasting you money?
You'll see in my sig i have pc4000, which i bough coz i overclocking my cpu to 250fsb.

You may be able to underclock the ram, keep it in sync with you cpu, and then use the spare overhead to tighten up the timings - which would be a pro reason to buy it :)

But running ram async can not be the best option.
What is your setup, and do you intend to overclock?

FSB 200 mhz i think and bus speed is 800 MHZ i think and when i bought this computer at dell i had the option of 533 mhz but i chose 400 mhz but now i am going with 533 mhz so do you think i can go with 533 or do i have to stick with 400

care to tell me what computer it was or should i guess? :)

either way look in your bios and see if you have options to change the ram:fsb ratio to 3:4 if you can then you should be able to get some benifit from the ddr533

Only Intel Prescott's support DDR2, AMD CPU's don't support DDR2 so its a moot point, you'll have to go with DDR anyway. The upside is that AMD's using only DDR memory is easily as fast as an Intel chip using DDR2 for less money.

Rumor has it that the Venice and San Diego cores can support DDR2 but I haven't heard of anyone doing it and AMD has yet to announce it if it's true.

AMDs support for DDR2 is supposedly coming when they switch to new sockets (again), sometime 2006
 
I think I've seen one or two AMD laptops that support DDR2, but I could be wrong. (It was one of the computers that we have on sale at work, it might have been a desktop, too..., I'll check tonight ;))

it doesn't matter if it's a desktop or a laptop, they do not make amd's that have ddr2 ram. If you see it, then its wrong.
