Memory Samsung M321RYGA0PB2-CCP 96GB DDR5 6400MHz ECC RDIMM

Samsung M321RYGA0PB2-CCP is a server DDR5 ECC RDIMM module with a capacity of 96GB, aimed at serious server and workstation configurations that operate 24/7. The frequency of 6400 MHz and peak bandwidth of 51.2 GB/s give you high memory bandwidth for loaded databases, virtualization, and heavy compute tasks. Thanks to ECC and the Registered DIMM design with RCD and PMIC, the module is optimized for stability and predictable behavior under constant load. This is not "gamer" RAM, but a serious server component, compliant with the JEDEC JESD79-5 DDR5 SDRAM standard.

What you get

With 96GB in a single module, you can increase the server's total capacity with fewer occupied slots, which helps with better airflow and more flexible configurations (more RAM per CPU socket). The DDR5-6400 speed and 72-bit ECC data path (12GX72 logical organization) are key for multi-core platforms where memory bandwidth is often a bottleneck. ECC and support for features like Chipkill/SDDC (depending on the platform) minimize the risk of silent memory errors – important for virtual machines, financial applications, or scientific computing. The Registered design with RCD, PMIC, and SPD5 hub with temperature sensor provides better control over signals, power, and monitoring, which helps with stability on densely populated server boards. The operating temperature range of 0 °C to 95 °C is a serious margin for 24/7 server conditions.

• Capacity 96GB DDR5 ECC RDIMM – large memory volume in a single module, ideal for servers and workstations needing lots of RAM without filling all DIMM slots.
• Frequency 6400 MHz and peak 51.2 GB/s – high bandwidth for applications sensitive to memory bandwidth, such as virtualization, in-memory databases, and analytical workloads.
• ECC with 72-bit data path (12GX72) – error correction at the module level, which increases reliability and reduces the risk of data corrupted by single-bit or multi-bit errors, depending on the platform.
• RDIMM design with RCD, PMIC, and SPD5 hub – registered module with better signal and power management, plus a built-in temperature sensor for more precise monitoring in server chassis.
• DDR5 SDRAM per JEDEC JESD79-5 – standard DDR5 implementation for compatibility with server platforms supporting DDR5 ECC Registered memory.
• Compatibility with server and workstation boards – designed for DDR5 ECC Registered RDIMM platforms, including Intel Xeon 6 and AMD EPYC 9004/9005, when supporting DDR5-6400 RDIMM.
• Operating voltage 1.1 V and range 0 °C – 95 °C – optimized for energy efficiency and stability in 24/7 environments with elevated temperatures.
• 288-pin RDIMM form factor, height 31.25 mm – standard physical size for server boards, suitable for densely packed rack servers.

Who it is suitable for

This memory is for administrators and power users who are building or upgrading servers and professional workstations with Intel Xeon 6 or AMD EPYC 9004/9005 and for whom stability is critical. It is suitable for virtualization, databases, high-load web servers, and scientific or engineering applications where ECC and RDIMM are mandatory. It is not for gaming or standard desktop systems – there it simply will not be compatible.

The most meaningful aspect here is the combination of 96GB capacity, DDR5-6400 speed, and ECC RDIMM reliability, which allows you to heavily load your platform without sacrificing stability and predictable behavior during 24/7 operation.
