About the Samsung 64GB DDR5 RDIMM - DDR5 (M321R8GA0BB0-CQKOF)
Samsung 64GB DDR5 RDIMM (M321R8GA0BB0-CQKOF) is purpose-built for Intel Xeon Scalable processors, delivering 6400 MT/s performance across dual 32-bit sub-channels in a 2Rx4 rank configuration. This registered DIMM integrates on-die ECC and RCD buffering, making it the standard choice for mission-critical data center environments where memory reliability and throughput cannot be compromised. The 64GB capacity per module minimizes slot count while maximizing compute density—essential for organizations scaling multi-socket server deployments.
Operating at just 1.1V with CL46 latency and full JEDEC DDR5 compliance, the M321R8GA0BB0-CQKOF ensures compatibility across certified server platforms while maintaining thermal stability across 0°C to 85°C ranges. Samsung modules of this class are specified by storage architects and infrastructure teams building next-generation hyperscale clusters, where per-module capacity and signal integrity directly impact ROI. The 288-pin design and standard 1U server height guarantee seamless integration into existing rack layouts without thermal or mechanical conflicts.
