This RDIMM with ECC and registered signal buffering is engineered specifically for enterprise servers and workstations that demand uncompromising data integrity in virtualized environments and large in-memory databases. Its 64 GB dual-rank x4 configuration at DDR5-6400 ensures high bandwidth and superior memory interleaving efficiency while the 1.1 V operating voltage and on-die ECC help maintain rock-solid stability under sustained heavy workloads.
1. Expansive capacity per module maximizes VM density, letting heavy in-memory databases and large-scale enterprise applications coexist without memory pressure.
2. Breakthrough DDR5 transfer rates dramatically shorten data movement latency, accelerating real-time analytics and transactional workloads under high concurrency.
3. End-to-end ECC protection silently corrects single-bit errors and detects multi-bit corruption, safeguarding financial calculations and long-running scientific simulations.
4. Registered buffer technology stabilizes command and address signals across fully populated multi-socket platforms, enabling reliable scaling to multi-terabyte memory configurations.
5. Dual-rank x4 organization keeps memory channels deeply saturated, delivering steady throughput for virtualized hosts and container fleets even during peak consolidation.
The MTC40F2046S1RC64BH1R is a DDR5-6400 registered DIMM engineered for modern data centers. Each 64GB module integrates ECC to detect and correct single-bit errors, a critical safeguard against silent data corruption that can crash virtualized workloads or corrupt in-memory databases like SAP HANA. Registered signal type buffers address lines, enabling stable operation even when populating multiple DIMMs per channel in dense server configurations—this translates directly to predictable uptime for your virtualization clusters. The dual-rank x4 organization and 6400 MT/s bandwidth boost data interleaving and throughput, accelerating large-scale analytics and real-time transactional processing. With a low 1.1V operating voltage, power consumption drops measurably across racks, lowering total cost of ownership. Whether consolidating dozens of VMs or running an enterprise database entirely in memory, this module delivers the reliability, performance, and efficiency your infrastructure demands.
General Virtualization
For dense virtualization hosts, populate multiple 64GB RDIMMs across all memory channels to maximize capacity and bandwidth. A balanced configuration – for example, 8 or 16 modules in a dual-socket server – enables high VM density without overcommitting memory, and registered ECC ensures data integrity for sustained uptime.
In-Memory Database
In-memory workloads demand both capacity and low latency. Deploy these 64GB DDR5-6400 RDIMMs in a symmetrical 8-channel layout per socket to achieve the memory footprint required for large Redis or SAP HANA datasets. Dual-rank x4 modules deliver strong signal integrity and allow the platform to run at rated 6400 MT/s, improving query throughput.
High-Performance Computing
HPC clusters benefit from maximum bandwidth per node. Install one DIMM per channel (1DPC) with these high-speed Registered DIMMs to sustain 6400 MT/s and feed all CPU cores efficiently. A six- or eight-module kit per node provides 384–512 GB of balanced, low-jitter memory for MPI and simulation codes, while ECC guards against soft errors during long-running jobs.
This rigorously tested 64GB DDR5 RDIMM is compatible with Dell PowerEdge R760, HPE DL380 Gen11, Lenovo SR650 V3.
Q: Can I mix this MTC40F2046S1RC64BH1R with other memory modules of different brands or speeds?
A: Mixing registered ECC modules of different brands or speeds is strongly discouraged. It can cause signal integrity issues, unstable operation, or POST failures in server platforms. Always populate with identical, validated modules.
Q: Is this memory compatible with my system? (Intel Xeon or AMD EPYC server)
A: This DDR5-6400 64GB RDIMM is engineered for 4th Gen Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series platforms. Confirm your motherboard’s QVL and support for dual‑rank x4 modules before ordering.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server board’s manual. Generally, populate balanced channels per memory controller first—typically slots 1A, 1B, then 2A, 2B. Symmetrical interleaving across both sockets maximizes bandwidth and minimizes latency.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC‑compliant registered ECC server DIMM. It does not support overclocking, XMP, or EXPO profiles, as server memory prioritizes absolute data integrity and 24/7 stability under ECC protection.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1‑year warranty. Enterprise RDIMMs typically exhibit an AFR below 0.5% in properly cooled environments. The advanced ECC and rigorous testing ensure mission‑critical reliability for your deployments.
