Memory Kingston RAM Server Premier 16GB DDR5 5600 UDIMM CL46 - KSM56E46BS8-16MH

This is a 16GB DDR5 5600 ECC UDIMM module from the Kingston Server Premier series, aimed at servers and workstations. The memory is designed for stability and predictability – with a locked BOM design and JEDEC compatibility for long-term configurations. It operates at 5600 MT/s at 1.1 V and uses ECC for error correction, which is key for systems where uptime and reliability are paramount. The form factor is a standard 288-pin ECC UDIMM, without a heatsink and without RGB – focus entirely on functionality, not looks.

What you get

With this module, you get 16GB capacity in a single module (1 x 16GB), allowing you to fill slots gradually and retain the option for a future upgrade. ECC support (including On-Die ECC and x72 ECC architecture) reduces the risk of silent memory errors – important for databases, virtualization, and critical services. The locked BOM in the Server Premier series means fixed DRAM chips, PMIC, SPD hub, thermistor, and PCB, which is a huge plus when maintaining many machines and wanting consistent behavior during replacement or adding RAM. Support for operating temperatures from 0°C to +95°C provides a good temperature range for loaded 24/7 systems. Sideband access via I3C/I2C and support for Hard/Soft Post Package Repair facilitate monitoring and service in more serious infrastructures.

• 16GB DDR5 5600 ECC UDIMM module, suitable for servers and workstations that require high memory throughput.
• ECC support (x72, two independent x36 I/O subchannels + On-Die ECC) to minimize memory errors and provide higher reliability under critical loads.
• Server Premier series with locked BOM – fixed DRAM, PMIC, SPD hub, thermistor, and PCB for consistent behavior and easier validation in server environments.
• Frequency 5600 MT/s and latency CL46, optimized for platforms with DDR5 ECC UDIMM support.
• Voltage 1.1 V, JEDEC compatibility, RoHS compliant and halogen-free construction to meet industrial standards.
• Operating temperature 0°C to +95°C and UL rating 94 V-0, suitable for 24/7 systems and more demanding conditions.
• 288-pin connector with gold plating and compact dimensions 133.35 x 1.27 x 31.25 mm, without a heatsink and without RGB, with a classic green board.

Who it is suitable for

This module is for admins and enthusiasts who build or upgrade servers and workstations with support for DDR5 5600MT/s ECC UDIMM. It is suitable for virtualization, file servers, business applications, dev/test environments, and more serious workloads where stability is more important than „tuning“ timings and RGB. It is not aimed at typical gaming machines, especially if the motherboard/CPU does not support ECC UDIMM.

The combination of ECC, Server Premier locked BOM, and high DDR5 5600 frequency makes this module a very sensible choice if you are looking for predictable, easy-to-maintain memory for a serious server or workstation build.
