Compared to previous modules, DDR3 only worked at 1066Mhz, 1333Mhz, 1600Mhz and maxed out at 1866Mhz, but DDR4 SQR-SD4M and SQR-SD4I modules offer superior performance at speeds of 2133Mhz and 2400Mhz for faster data processing. Furthermore, DDR4 runs more efficiently at just 1.2V, which means up to 20% less power consumption than DDR3. Aimed at ne
