Module

DDR5 is the 5th generation of Double Data Rate Synchronous Dynamic Random Access Memory, aka DDR5 SDRAM. It began in 2017 by the industry standards body JEDEC (Joint Electron Device Engineering Council) with input from the leading global memory semiconductor and chipset architecture vendors, including Kingston, DDR5 is designed with new features for higher performance, lower power, and more robust data integrity for the next decade of computing. DDR5 debuted in 2021.

SKU: Memory Module-DDR5 Category:

Greater starting speed performance

DDR5 debuts at 4800MT/s*, while DDR4 tops out at 3200MT/s, a 50% increase in bandwidth. In cadence with compute platform releases, DDR5 has planned performance increases that will scale to 6400MT/s.

Reduced Power / Increased Efficiency

At 1.1V, DDR5 consumes ~20% less power than DDR4 equivalent components at 1.2V. While conserving battery life in laptops, it also has a significant advantage for enterprise servers working around the clock.

PMIC

DDR5 modules feature on-board Power Management Integrate Circuits (PMIC), which help regulate the power required by the various components of the memory module (DRAM, Register, SPD hub, etc). For server class modules the PMIC uses 12V, and for PC class modules the PMIC uses 5V. This makes for better power distribution than previous generations, improves signal integrity, and reduces noise.

SPD Hub

DDR5 utilizes a new device integrating the Serial Presence Detect (SPD) EEPROM with additional hub features, managing access to the external controller and decoupling the memory load on the internal bus from external.
