Micron MTC20F2085S1HC88XD1R 32GB DDR5 MRDIMM 8800MT/s | ECC Memory

General

Engineer's Note

This MRDIMM module is engineered for next-generation server platforms, delivering exceptional bandwidth for memory-intensive workloads such as large-scale virtualization and in-memory databases. Its dual-rank x4 configuration and registered signaling maximize signal integrity and capacity density, while ECC ensures end-to-end data reliability under sustained high-throughput conditions.

Technical Specs & Insights

1. MRDIMM architecture pushes per-channel bandwidth to new extremes, enabling AI accelerators and in-memory analytics to ingest massive data streams without stalling compute pipelines.
2. ECC correction delivers end-to-end data integrity, silently neutralizing memory errors that would otherwise corrupt financial records or compromise long-running scientific simulations.
3. Registered buffering stabilizes command and address paths under the heaviest population loads, letting a hypervisor host more virtual machines without risking signal degradation.
4. Dual rank x4 arrangement maximizes page interleaving across modules, keeping throughput steady during the mixed random-access patterns of multi-tenant cloud instances.
5. Operating at the pinnacle of the DDR5 speed spectrum, this module slashes effective access latency, directly accelerating cache-line refills for latency-critical microservices and real-time trading engines.

Why These Specs Matter

Introducing the MTC20F2085S1HC88XD1R, a 32GB DDR5 MRDIMM purpose-built for enterprise servers. Its four key attributes translate directly into mission-critical dependability. First, the blistering 8800 MT/s speed and dual-rank x4 design feed virtualization clusters exceptional bandwidth, preventing VM stalls under heavy consolidation. Second, ECC error correction safeguards in-memory databases like SAP HANA by eliminating bit-flip risks that could corrupt financial records. Third, the registered buffer maintains signal integrity even when every DIMM slot is populated, so you can scale to terabytes of reliable memory. Fourth, MRDIMM’s ability to access multiple ranks in parallel keeps throughput high during mixed read/write operations, crucial for real-time analytics and AI inference. This isn’t just a module—it’s an insurance policy for data integrity and non-stop performance.

Endurance & Reliability

This capacity planning guide covers a 32GB DDR5-8800 MRDIMM, a registered ECC server memory module built for high-performance data centers.

General Virtualization
For virtualized environments, balance capacity and bandwidth. Populate each memory channel of a dual-socket server with one 32GB module per CPU (1 DIMM per channel), delivering 256GB per socket at the full 8800 MT/s speed. This symmetric population ensures predictable NUMA behavior and supports dense VM consolidation without throttling.

In-Memory Database
In-memory databases demand large capacity and sustained throughput. Install two 32GB MRDIMMs per channel (2DPC) to reach 512GB per CPU, accepting a modest speed reduction to ~6400 MT/s. This configuration provides over 1TB of reliable, ECC-protected memory per node for real-time analytics and large caches.

High-Performance Computing
HPC codes are bandwidth-hungry. Use a single 32GB MRDIMM per channel (1DPC) to maintain the peak 8800 MHz clock, maximizing memory bandwidth per core. A fully configured dual-socket system with 16 modules yields 512GB of ultra-fast capacity, ideal for simulation and modeling workloads.

Verified Compatibility

Proven compatible with Dell PowerEdge R670/R770, Lenovo SR650 V4, Supermicro SYS-221H-TNR, HPE DL380 Gen12 after rigorous testing.
