Alright I got a question... would 2 512mb of SDRAM sticks be faster then a total size of 2 256mb DDR RAM sticks? Reason I ask is I got spares lying around and my computer can either take SDRAM or DDR, and I only got 512 of the DDR and 1024 of the SDRam... so which one would you guys prefer I use for now?

Unless your motherboard is setup to run both kinds of memory you cannot run one or the other on your motherboard. Sdram has 168 pins and DDR ram has 184 pins. As the name suggests Double Data Rate (DDR) SDRAM doubles the read/write speed of previous generation SDRAM memory. Unlike previous generation SDRAM that used only one edge of each clock pulse, DDR SDRAM references both edges of the clock pulse, effectively doubling the rate of data retrieval out of the memory.
