What is DDR, DDR stands for double data rate which is a signaling method that allows higher clocking speeds. The first set was of course the DDR then the DDR2, and now we have the DDR3. The only difference is the speed of the memory. The motherboard is now equipped to handle memory in a dual channel. This means more memory and faster access to that memory for the computer to use. The higher or faster the chip, the more expensive it gets. Honestly right now for the money DDR2 would be the cheapest rout and with little to no difference from the DDR3. For those that still want to know what memory is, it is also called RAM. Random Access Memory, and is used by the computer to store programs that are being used by the computer so it can be access quickly.
I was currently reading about motherboards that can handle DDR2 or DDR3 memory, but not both. The motherboard can only handle one type, with this being said I was curious about why a MoBos that suported DDR2 memory could handle a Grphics card with DDR3 memory. I recently found out that the graphics card actually suports its self like a self contained mini computer. This will allow for buying cheaper memory and still go for a faster graphics card.
I have always been interested in computers and all that it pertains. I have gone to college for computer repair and maintenance and I am currently going back to school for IT in multimedia and visual communications. I know that their is a lot of questions as well as unanswered questions out there. I am going to start blogging information that deals with Windows and PC related topics. If there are any questions you would like to know please ask. I am going to try to keep the tech talk related to a low tech audience.
