In addition to double pumping the data bus as in DDR SDRAM transferring data on the rising and falling edges of the bus clock signal , DDR2 allows higher bus speed and requires lower power by running the internal clock at half the speed of the data bus. The two factors combine to produce a total of four data transfers per internal clock cycle. Alternatively, DDR2 memory operating at twice the external data bus clock rate as DDR may provide twice the bandwidth with the same latency. Both performed worse than the original DDR specification due to higher latency, which made total access times longer. These chips are mostly standard DDR chips that have been tested and rated to be capable of operation at higher clock rates by the manufacturer. Such chips draw significantly more power than slower-clocked chips, but usually offered little or no improvement in real-world performance. DDR2 started to become competitive against the older DDR standard by the end of , as modules with lower latencies became available. During an access, four bits were read or written to or from a four-bit-deep prefetch queue. This queue received or transmitted its data over the data bus in two data bus clock cycles each clock cycle transferred two bits of data. DDR2's bus frequency is boosted by electrical interface improvements, on-die termination , prefetch buffers and off-chip drivers. However, latency is greatly increased as a trade-off. Thus, DDR2 memory must be operated at twice the data rate to achieve the same latency. This packaging change was necessary to maintain signal integrity at higher bus speeds. Power savings are achieved primarily due to an improved manufacturing process through die shrinkage, resulting in a drop in operating voltage 1. The lower memory clock frequency may also enable power reductions in applications that do not require the highest available data rates.

However - the chipsets ddr2 6400 designed to use memories of mixed speeds in the two slots, and then defaults to the slower speed of the two. Archived from the original PDF on

DDR2 started to become competitive against the older DDR standard by the end of , as modules with lower latencies became available. The SPD information is supposed to indicate where the optimum performance would be, as well as recommended secondary settings at a slower bus speed. At least one manufacturer has reported this reflects successful testing at a higher-than-standard data rate [9] whilst others simply round up for the name. Alternatively, DDR2 memory operating at twice the external data bus clock rate as DDR may provide twice the bandwidth with the same latency. Retrieved We pride ourselves in selling only the best Dell parts. The front side bus is at MHz, but the memory bus is actually at a max MHz. Unican best sale 4gb ddr2 ram pc2 mhz sodimm laptop ram.
