This VLP RDIMM with ECC and registered signaling is purpose-built for space-constrained server platforms, making it ideal for virtualization and in-memory database workloads that demand uncompromising data integrity. Its single-rank x4 configuration and very low-profile form factor optimize thermal clearance and signal integrity in dense 1U blade servers while delivering reliable DDR4-2400 performance at a power-efficient 1.2V.
1. ECC protection silently detects and corrects data errors, safeguarding transactional integrity in mission-critical database servers and preventing costly data corruption.
2. Registered buffering reduces electrical load on the memory controller, enabling higher module counts for dense virtualization hosts without sacrificing signal stability.
3. Very low-profile design fits unobtrusively into compact blade and edge servers, improving airflow and thermal headroom in space-constrained racks.
4. Generous per-module capacity provides substantial headroom for memory-hungry hypervisors and in-memory analytics, reducing the need for immediate upgrades.
5. Conservative clock speed delivers balanced bandwidth with minimal power draw, optimizing throughput for steady-state enterprise workloads while lowering overall energy costs.
In the data center, every millisecond of latency and every undetected memory error carries a direct cost. The Micron MTA18ADF2G72PZ-2G3A1IG is a server-class VLP RDIMM designed to eliminate those risks. Its ECC technology continuously scans for and corrects single-bit flips—silent corruptions that, in a virtualization cluster hosting hundreds of VMs, could cascade into node failures or corrupt critical in-memory databases like Redis or SAP HANA. The registered signal buffer allows you to fully populate high-density server boards without command bus degradation, meaning you can confidently scale your hypervisor farm to multi-terabyte footprints while maintaining rock-solid stability. Its very low profile form factor optimizes airflow in dense 1U or blade enclosures, reducing fan power draw and preventing thermal throttling that silently saps performance. And with a single-rank x4 organization at 2400MT/s, this module balances low latency with ample bandwidth, accelerating transactional throughput in database acceleration workloads where every query competes for memory cycles. For your enterprise, that translates directly into fewer application interruptions, predictable latency under load, and a longer, cooler-running infrastructure life.
This 16GB DDR4-2400 ECC Registered VLP RDIMM (PC4-19200, single-rank x4) is purpose‑built for server environments where reliability and density matter. Use the following capacity planning guidance for typical workloads.
General Virtualization
Populate one DIMM per memory channel to keep bandwidth balanced across all NUMA nodes. A dual‑socket server with 12 channels (six per CPU) filled with twelve 16GB modules delivers 192 GB, comfortably hosting 40–50 moderate VMs. Leave at least half the slots empty to preserve easy scaling; avoid mixing different DIMM ranks in a single channel.
In‑Memory Database
Maximise capacity while staying within the platform’s rank limits. Installing a 16GB VLP RDIMM in every available slot (e.g., 24‑slot server) provides 384 GB, enough for a mid‑size in‑memory database. Use the single‑rank modules to keep electrical loading low and maintain 2400 MT/s speed. For larger datasets, scale horizontally by adding identical nodes.
High‑Performance Computing
To fully exploit memory bandwidth, fit one 16GB module in every populated channel. A dual‑socket node with 16 memory channels (eight per socket) running sixteen modules yields 256 GB of uniform, high‑bandwidth memory, reducing NUMA penalties. The VLP form factor also improves airflow in dense 1U or blade compute racks.

Q: Can I mix this MTA18ADF2G72PZ-2G3A1IG with other memory modules of different brands or speeds?
A: We strongly advise against mixing modules of different brands, speeds, or rankings. Mixing can force the memory controller to downclock to the lowest common speed, introduce latency mismatches, and compromise system stability in server environments.
Q: Is this memory compatible with my system?
A: This is a DDR4-2400 ECC Registered VLP RDIMM. It is compatible with servers using Intel Xeon E5-2600 v3/v4 or Xeon Scalable platforms, and select AMD EPYC platforms, provided the board supports 288-pin registered DIMMs at 1.2V.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with the farthest slot from the CPU. Always follow the motherboard’s memory population guide to balance channels and maximize bandwidth, typically filling blue slots first for dual-channel configurations.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise-grade registered server DIMM adhering to JEDEC standards. It does not support XMP, overclocking, or voltage adjustments, as stability and data integrity are paramount in server environments.
Q: What warranty and typical failure rate can I expect?
A: This Micron module is backed by a 1-year warranty. Enterprise DDR4 RDIMMs exhibit extremely low annualized failure rates, typically below 0.1%, ensuring reliable 24/7 operation under specified thermal and voltage conditions.
