the way, there has been a push in the DDR manufacturing industry to
have the present type of memory run faster, alongside the blazing processor
speeds now available in the PC marketplace. The current iteration of
DDR has begun to show its' limitations in memory bandwidth with both
PC2100/PC2700 DDR platforms. By causing a bottleneck in the performance
of these new processor speed demons, memory is starting to be the limiting
factor to the question, "how fast can you go?"
DDR3 is the next-generation, high-performance solution for CPU systems. DDR3 memory are twice as fast as today's highest speed DDR2 memory products. Select your DDR3 Memory from the following.
DDR2 Memory RAM
Note: DDR2-xxx denotes data transfer rate, and describes raw DDR chips, whereas PC2-xxxx denotes theoretical bandwidth (though it is often rounded up or down), and is used to describe assembled DIMMs. Bandwidth is calculated by taking transfers per second and multiplying by eight. This is because DDR2 memory modules transfer data on a bus that is 64 data bits wide, and since a byte comprises 8 bits, this equates to 8 bytes of data per transfer.
Some manufacturers label their DDR2 modules as PC2-4300 instead of PC2-4200, PC2-5400 instead of PC2-5300, and PC2-8600 instead of PC2-8500. At least one manufacturer has reported this reflects successful testing at a higher-than standard data rate, whilst others simply use the alternate rounding as the name, as described above.
