well my computer is running a memory of 256mb 400 Mhz DDR SDRAM it specifies that it has DDR and SDRAM i never heard such thing does it DDR and SD different?... well im a noob actually.... the fact is i want to upgrade my memory which is a branded one, a PCI and has a memory of 256 and im using a HP pavilion.... MY question is when i upgrade my memory what should i ask them? DDR or SD? or it`s just one?

If your wanting to upgrade,ask for PC3200 (400MHz) SD DDR RAM, but if you ask for DDR they will know what you mean.

so your saying "Axegrinder" that there is a DDR SDRAM existing combined?? because when i say to a dealer if they has a DDR they will ask me if it`s a DDR1 or DDR2... PC-400, or 533 that`s what they asking me do i have to say i want a SD DDR Ram? instead of asking DDR only

Ask for PC3200 DDR1 RAM. Excuse me not making it clear enough.
