Overview

The SK Hynix / Samsung 64GB DDR4-3200 ECC RDIMM is a high-capacity, enterprise-grade registered memory module engineered for demanding server environments. Operating at 3200 MT/s with full ECC (Error-Correcting Code) support and registered buffering, this RDIMM delivers the reliability, speed, and stability that mission-critical infrastructure demands. Sourced in "New Pulled" condition from premium OEM server platforms, each module is functionally equivalent to new, having been carefully removed from factory-fresh or lightly deployed systems before reaching the end user.

Dual-sourced from two of the world's most respected DRAM manufacturers — SK Hynix and Samsung — this module guarantees consistent quality regardless of which brand ships.

Key Features

• 64GB High Density: Maximise memory capacity per DIMM slot, reducing the number of modules required to reach target system RAM configurations — critical for virtualisation-heavy and in-memory database workloads.
• DDR4-3200 Speed Grade: Delivers a peak transfer rate of 25,600 MB/s, ensuring fast memory bus throughput to support modern multi-core Xeon and EPYC processors.
• ECC (Error-Correcting Code): Automatically detects and corrects single-bit memory errors in real time, dramatically reducing unplanned downtime and data corruption risk in production environments.
• Registered (Buffered) Architecture: The on-module register offloads electrical load from the memory controller, enabling high DIMM population densities without signal integrity degradation.
• 1.2V Low-Voltage Operation: Optimised power consumption compared to DDR3 predecessors, reducing thermal output and operating costs in dense rack deployments.
• New Pulled Condition: Modules are extracted from new or virtually new OEM systems, thoroughly inspected, and tested — delivering like-new performance at a more accessible price point.
• Dual-Source Flexibility: SK Hynix and Samsung are interchangeable at the specification level, allowing procurement continuity even during component supply fluctuations.

Technical Architecture

The 64GB DDR4-3200 ECC RDIMM is built on a dual-rank, 288-pin form factor compliant with JEDEC DDR4 standards. The registered buffer (RCD) on the module decouples command and address lines from the DRAM chips, allowing the memory controller to drive a single electrical load regardless of the number of DRAM devices behind the buffer. This architecture is essential in multi-DIMM configurations found in dual-socket and quad-socket server platforms.

ECC is implemented using an additional set of DRAM chips dedicated to parity and correction data. The memory controller continuously monitors all read operations for bit errors. Single-bit errors are corrected transparently, while double-bit errors are detected and flagged, enabling graceful system response rather than silent data corruption. This level of memory integrity is a mandatory requirement for financial databases, healthcare systems, and telecommunications infrastructure.

The module operates at a nominal voltage of 1.2V DC and supports industry-standard XMP and SPD profiles, ensuring automatic configuration at DDR4-3200 when installed in a compatible platform without requiring manual BIOS adjustments. Thermal sensors embedded in the SPD EEPROM allow the platform's BMC to monitor module temperature in real time, supporting proactive thermal management strategies in high-density deployments.

Performance

At 3200 MT/s, this module delivers a theoretical peak bandwidth of 25.6 GB/s per channel. In a typical dual-socket server with 16 DIMM slots fully populated, aggregate memory bandwidth can exceed 400 GB/s, enabling memory-intensive workloads such as SAP HANA, Redis, Apache Spark, and real-time analytics engines to operate at peak efficiency. The DDR4-3200 speed grade is the highest standardised DDR4 frequency, making this module a future-aligned investment for platforms that support it.

In virtualised environments running VMware vSphere, Microsoft Hyper-V, or KVM, higher per-DIMM density directly translates to more virtual machines per host and better NUMA locality — both critical factors in reducing VM sprawl and licensing costs. A server with 16 x 64GB RDIMMs achieves 1TB of addressable RAM, sufficient to host hundreds of lightweight VMs or dozens of memory-intensive enterprise application servers.

Compatibility

This RDIMM is compatible with a broad range of enterprise server platforms that support DDR4-3200 registered memory, including:

• Intel Xeon Scalable (Ice Lake / Cooper Lake / Cascade Lake): Full compatibility with 3rd Gen Xeon platforms at native 3200 MT/s speeds.
• AMD EPYC (Milan / Rome): Supported across EPYC 7002 and 7003 series platforms with appropriate BIOS microcode.
• HPE ProLiant Gen10 Plus: Including DL360, DL380, DL560, and DL580 series.
• Dell PowerEdge R640, R740, R750, R840, R940: Validated for use in standard DIMM slots with DDR4-3200 support.
• Lenovo ThinkSystem SR630 V2, SR650 V2, SR850 V2: Compatible with Lenovo's enterprise memory validation framework.
• Supermicro X12 and H12 Series: Suitable for Supermicro platforms with Intel and AMD DDR4-3200 support.

Always verify your platform's QVL (Qualified Vendor List) and BIOS version prior to deployment. Our technical team at Omnixon can assist with compatibility verification for your specific server model.
