This 64GB DDR4-3200 registered ECC module is purpose-built for server platforms running memory-intensive workloads such as virtualization, in-memory databases, and data-critical applications where uncompromised data integrity is essential. Its dual-rank DIMM configuration boosts bandwidth through rank interleaving, while the registered signal type and 1.2V operating voltage ensure stable signaling and high energy efficiency even in densely populated 288-pin server systems.
1. Sixty-four gigabyte capacity per module maximizes memory footprint per channel, enabling dense virtualization hosts to run far more active VMs without resorting to slower swap storage.
2. 3200MT/s speed fuels higher sustained bandwidth, sharply reducing data fetch times for in-memory databases and real-time analytics under heavy concurrent loads.
3. ECC error correction automatically catches and repairs single-bit faults, eliminating silent data corruption risks in financial ledgers and long-duration scientific computations.
4. Registered signal buffering restrains electrical loading across fully populated server boards, preserving rock-solid command integrity when scaling to terabyte-class memory pools.
5. Dual rank interleaving exploits bank-level parallelism to keep the data bus fully utilized, cutting latency jitter for multi-tenant cloud services contending for shared memory resources.
Designed specifically for enterprise servers, the Micron MTA36ASF8G72PZ-3G2B2UL is a 64GB DDR4-3200 RDIMM that transforms how your data center handles critical workloads. Its ECC technology continuously detects and corrects single-bit memory errors, directly preventing silent data corruption in financial transaction databases or in-memory analytics platforms like SAP HANA, where even a single flipped bit can mean incorrect calculations or system downtime. The registered buffer onboard stabilizes the command and address signals, allowing you to populate all memory channels densely without signal degradation; when you are scaling a virtualization cluster running dozens of VMs per host, this signal integrity keeps every virtual machine responsive under heavy load, avoiding the intermittent crashes that unregistered modules often cause. With a dual-rank architecture delivering bandwidth-efficient interleaving, combined with a 3200MT/s speed at a low 1.2V, this module provides the throughput needed for real-time data ingest in Redis or Memcached without driving up your thermal envelope. Together, these attributes mean fewer crashes, predictable uptime, and the confidence to consolidate more virtual services onto a single platform.
General Virtualization
For dense virtualization hosts running multiple VMs, populate all memory channels evenly with identical 64GB RDIMMs to maximize capacity and memory bandwidth. A dual-socket server with 16 DIMM slots per CPU can reach 2TB using 32 x 64GB modules, comfortably supporting hundreds of moderate workloads while leaving headroom for memory overcommit. Stick to one DIMM per channel initially to maintain 3200MT/s speed, adding a second DIMM per channel only when scaling beyond 50% slot utilization.
In-Memory Database
Low-latency, high-capacity requirements demand populating all channels with these 64GB dual-rank RDIMMs to achieve both maximum bandwidth and rank interleaving. For a Redis or SAP HANA node, configure at least 12 identical modules per socket (one per channel) to sustain 100+ GB/s throughput, avoiding mixed capacities that degrade NUMA locality. Always install in matched sets and balance across memory controllers to prevent performance cliffs under heavy OLTP loads.
High-Performance Computing
HPC clusters benefit from the 3200MT/s speed and ECC reliability when running tightly coupled MPI jobs. Fill every channel with a single 64GB DIMM to deliver 8 memory channels × 25.6 GB/s peak bandwidth on platforms like AMD EPYC, fully saturating the memory fabric for CFD or weather simulations. Avoid exceeding one DIMM per channel unless memory capacity-bound, as the frequency drop to 2933MT/s or lower on many platforms will reduce floating-point throughput.
Rigorously tested 64GB DDR4-3200 RDIMM compatible with Dell PowerEdge R750, HPE DL380 Gen10 Plus, Lenovo SR650 V2, and more.
Q: Can I mix this MTA36ASF8G72PZ-3G2B2UL with other memory modules of different brands or speeds?
A: Mixing RDIMMs is strongly discouraged. This 64GB DDR4-3200 ECC Registered module requires matching ranks, timings, and voltage to maintain signal integrity and avoid stability issues in server environments.
Q: Is this memory compatible with my system?
A: It is compatible with servers supporting DDR4-3200 ECC RDIMMs, such as Intel Xeon Scalable (2nd Gen+) or AMD EPYC 7002/7003 platforms. Verify your motherboard’s qualified vendor list for this specific Micron part number.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per memory channel, typically starting with the first white slot on each CPU’s channel. For dual-rank modules, fill one DIMM per channel first to maintain 3200MT/s speed, then add a second pair symmetrically.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server RDIMM operating at standard 3200MHz (PC4-25600) with CL22. It does not feature XMP and is not designed for overclocking, prioritizing data integrity and platform stability.
Q: What warranty and typical failure rate can I expect?
A: This Micron module includes a 1-year warranty. Enterprise RDIMMs exhibit extremely low annualized failure rates, typically under 0.5%, thanks to rigorous screening, ECC, and temperature-managed operation.
