DDR5 Value
SMART's DDR5 Value RDIMMs are designed to meet increasing needs for efficient performance in a wide range of applications including cloud computing, and data center processing. The DDR5 memory provides developers with twice the performance (4800 to 6400 MT/s) and improved power efficiency in comparison to DDR4 by using an on-DIMM 12V voltage regulator (PMIC) and 1.1 I/O Voltage.
DDR5 also improves scaling performance without degrading channel efficiency at higher speeds. This increased performance is achieved by doubling the burst length to BL16 and bank-count to 32 from 16. For increased reliability and efficiency, a DDR5 DIMM utilizes two 40-bit fully independent sub-channels on the same module. DDR5 memory modules have a maximum die density of 64Gb and hence are capable of having a much higher DIMM storage capacity.
