DDR SDRAM or DDR RAM (Double-Data-Rate Synchronous Dynamic Random Access Memory) happens to be a sort of exceedingly swift computer memory. It is based on the same architecture as SDRAM even though there is a difference. It makes use of the clock signal in a different way in order to transfer twice the data in the same amount of time.

Note this down that in any computer system the clock signal is an oscillating frequency that is used to organize interaction between digital circuits. It other words, it plays a prominent role in synchronizing communication. Digital circuits, in this context, that are designed to run on the clock signal may act in response at the increasing or declining edge of the signal.

Focus on this aspect as well. While SDRAM memory chips make the most of only the rising edge of the signal to transfer data, DDR RAM transfers data on both the rising and falling edges of the clock signal. For this reason, DDR RAM is, in actual fact, twice as fast as SDRAM.

DDR RAM, in general, is made for processors 1GHz and faster. Designations like PC1600 DDR SDRAM and PC2100 DDR SDRAM coincide with particular FSB and CPU speeds. AMD and Intel bring into play different schemes to designate processor speed, and a variety of technicalities in RAM designations and standards can be perplexing.

It’s the time for you to enter the center stage. You ought to verify your motherboard manual to distinguish whether DDR RAM is consistent with your system.
