DDR2 is a 240-pin module, DDR is a 184-pin module. When i got home, realised that I should have actually bought the same RAM rated at PC3-8500 (1066Mhz) which came with my Macbook Aluminium (Late 2008). Clock speed of DDR3 can be somewhere between 800 and 2133 MHz, while DDR4’s is 2133 MHz. Backward compatibility is a hardware or software program or system that could operate with the interface of an older version of the same concept. Not only this, you cannot mix RAM with different DDR versions on any motherboard. It can also run at a higher frequency, making it ideal for gaming and other high-performance computing tasks. 50 Vs. In SDRAM modules, the numbers that come after the "PC" refer to the speed of the system's front-side bus. In automatic selection mode the BIOS would therefore run our example memory at 1333. Not only is the key notch of each DDR generation different (please refer to Figure 1 above), but the DDR4 pin size and arrangement is different from DDR3. DDR3 is an older memory technology with lower bandwidth and higher latency, while DDR4 offers improved performance, lower power consumption, and higher data transfer rates. 4 Gbps per pin at max, but initially, it stays at 4.
