What is DDR4 RAM?

• DDR4 SDRAM is the abbreviation for "double data rate fourth generation synchronous dynamic random-access memory", the latest variant of memory in computing. DDR4 is able to achieve higher speed and efficiency thanks to increased transfer rates and decreased voltage. 

• The primary advantages of DDR4 over its predecessor, DDR3, include higher module density and lower voltage requirements, coupled with higher data rate transfer speeds. The DDR4 standard theoretically allows for DIMMs of up to 512 GiB in capacity, compared to DDR3's theoretical maximum of 128 GiB per DIMM.

• DDR4 also provides cyclic redundancy checks (CRC) for improved data reliability, on-chip parity detection for integrity verification of ‘command and address’ transfers over a link, enhanced signal integrity and other robust RAS features.
