What are DDR Speeds?
DD; It operates at 100MHz, 133MHz, 166MHz, 200MHz. So then what separates DDR memory from SDRAM? DDR memory can transfer data when the clock speed increases and decreases. For this reason, you are actually using memory at 200Mhz, 266Mhz or 333Mhz. The maximum bandwidth at 200Mhz is 1.6GB / s and at 266Mhz is 2.1GB / s. Therefore, DDR; It is also called PC1600 (200Mhz), PC2100 (266Mhz) and PC2700 (333Mhz) to indicate the maximum bandwidth.
DDR Output FSB Maximum Bandwidth
PC1600 (200Mhz) 100Mhz 1.6GB / s
PC2100 (266Mhz) 133Mhz 2.1GB / s
PC2700 (333Mhz) 166Mhz 2.7GB / s
PC3200 (400Mhz) 200Mhz 3.2GB / s
