Designed for enterprise servers, this 48 GB DDR5-6400 RDIMM leverages ECC and registered signaling to ensure data integrity in virtualization, in-memory databases, and dense multi-tenant workloads where silent corruption is unacceptable. Its dual-rank x8 organization and CL52 latency strike an optimal balance between high bandwidth and accessible density, maximizing memory interleaving on platforms that support 6400 MT/s registered DIMMs.
1. High module density allows servers to scale total memory capacity efficiently, increasing virtual machine consolidation ratios without performance degradation.
2. Ultra-fast data rate maximizes memory bandwidth, accelerating in-memory analytics and reducing query times for data-intensive workloads.
3. End-to-end error correction protects against data corruption, delivering the reliability required for mission-critical databases and financial systems.
4. Registering clock and command signals stabilizes multi-DIMM configurations, ensuring dependable operation under heavy server memory population.
5. Dual-rank organization leverages rank interleaving to improve command efficiency and sustaining high bandwidth under concurrent access patterns.
The MTC20F208XS1RC64B is a server-grade DDR5 Registered DIMM, purpose-built for data center workloads where reliability and scale are non-negotiable. Its four defining characteristics directly address the critical pain points IT architects face daily. First, the ECC technology continuously detects and corrects single-bit memory errors, preventing silent data corruption that could crash a hypervisor during live virtual machine migrations or introduce inaccuracies in financial transaction logs. Second, the Registered buffer isolates the electrical load from the memory controller, enabling a fully populated 48 GB module to remain stable inside a dense 2-socket server running dozens of virtualized containers without signal degradation, something unbuffered desktop memory simply cannot achieve under such load. Third, the dual-rank x8 organization interleaves accesses across internal banks, effectively doubling the bandwidth available for in-memory databases like Redis or SAP HANA; this means stock trade matching engines and real-time fraud analytics return results microseconds faster, directly impacting revenue. Finally, the 6400 MT/s DDR5 interface with a lean 1.1 V operating voltage delivers this performance while keeping thermal output in check across a row of 1U nodes, preserving cooling budget and sustaining base frequency under 24/7 operation. For your ESXi cluster or containerized microservice mesh, this module turns raw speed into business uptime and transactional consistency.
Server Memory Capacity Planning for 48GB DDR5-6400 RDIMM
This module is a registered ECC DDR5 DIMM for servers. Plan capacity according to workload as follows:
General Virtualization
Deploy modules in multiples of eight to populate all memory channels in dual-socket systems. A balanced 8 x 48GB (384GB) configuration supports dozens of VMs, while 16 x 48GB (768GB) suits high-density consolidation. ECC safeguards multi-tenant data integrity.
In-Memory Database
Utilize one DIMM per channel (1DPC) to maintain 6400MT/s speed. For databases like Redis or SAP HANA, configure 8 x 48GB (384GB) on a single socket or 16 x 48GB (768GB) across two CPUs to hold critical datasets in RAM. Registered design enables stable high-capacity operation.
High-Performance Computing
Maximize bandwidth by installing one 48GB module in every memory channel (8 per socket). This provides 384GB per CPU at peak speed for simulation workloads. If larger memory is required, populate a second DIMM per channel, accepting a slight frequency drop.
Rigorously validated RDIMM for server compatibility with Dell PowerEdge R760, HPE ProLiant DL360 Gen11, and Lenovo ThinkSystem SR650 V3.
Q: Can I mix this MTC20F208XS1RC64B with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is strongly discouraged. Mismatched timings and ranks often cause instability, POST failures, or degraded performance. Always use identical modules for server reliability.
Q: Is this memory compatible with my system?
A: This is a DDR5-6400 Registered ECC module for server platforms. It supports Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series. Verify your board accepts 288-pin RDIMMs and the required speed.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard’s population guide. Typically, populate the farthest slot per channel first, balance across memory controllers, and fill all channels equally to maximize bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This RDIMM operates strictly at JEDEC standard speeds. Server memory does not support overclocking or XMP profiles, as it prioritizes data integrity, stability, and continuous operation over performance tuning.
Q: What warranty and typical failure rate can I expect?
A: The module includes a 1-year warranty. Enterprise RDIMMs like this typically exhibit an annualized failure rate (AFR) well below 0.44%, reflecting rigorous testing and high reliability for critical workloads.
