This DDR2-400 Registered ECC RDIMM (Single Rank x8) at CL3 ensures strong data integrity and signal stability for legacy server platforms, making it a reliable choice for virtualization hosts and memory-intensive enterprise workloads where error correction is non-negotiable. Its low CAS latency and registered architecture reduce command-to-data delay while maintaining clean signal paths across dense memory channels, ideal for aging database servers still demanding 24/7 uptime.
1. End-to-end error correction eliminates silent data corruption, safeguarding financial ledgers and virtual machine integrity in multi-tenant hosting environments.
2. Registered command and address buffering preserves signal integrity under heavy channel loading, a prerequisite for stable operation in fully populated rack servers.
3. Single-rank architecture reduces electrical bus load, enabling memory channels to support maximum DIMM populations for seamless virtual machine density scaling.
4. The tightly focused capacity aligns with embedded baseboard management controllers and network appliance roles, delivering unwavering stability with minimal power draw.
5. The conservative clock rate provides deterministic memory throughput, ensuring predictable latency for real-time telecommunications and industrial control servers.
The Micron MT9HTF3272Y-40EB2 is a server-grade DDR2 registered DIMM engineered for mission-critical environments. Its ECC protection is your first line of defense against silent data corruption; in a virtualized cluster, a single uncorrected bit flip could instantly crash a hypervisor or poison database records, but this module detects and corrects those errors on the fly, preserving uptime. The registered buffer decouples the DRAM chips from the memory bus, enabling you to fully populate all slots for maximum capacity—vital when running dozens of memory-hungry VMs or a large in-memory database like Redis—without signal integrity issues. The single-rank x8 configuration reduces electrical loading, ensuring clean command and address signals even in densely filled servers. Additionally, the tightly tuned CAS 3 latency at 400MHz delivers a responsive 7.5ns access delay, accelerating the random read operations that dominate transactional workloads. Together, these characteristics give IT managers the confidence to consolidate workloads and run round-the-clock services with zero tolerance for failure.
The module MT9HTF3272Y-40EB2 is a 256 MB DDR2-400 registered ECC RDIMM tailored for server environments. Although its capacity is tiny by modern standards, the ECC and registered features make it suitable for specific legacy or embedded server roles.
General Virtualization
Running a legacy hypervisor (e.g., VMware ESXi 3.x) demands at least 1 GB. Install four identical modules, populating two per memory channel to enable dual-channel interleaving. The registered ECC ensures virtual machine stability and correctable error reporting on aging hardware.
In-Memory Database
A small Redis or Memcached instance caching session data can operate on 2 GB. Use eight modules and place one DIMM per channel to keep the setup single-rank, minimizing access latency. The ECC functionality prevents silent data corruption, which is critical for always-on cache services.
High-Performance Computing
A legacy compute cluster executing moderate parallel workloads can allocate 4 GB per node using sixteen modules. Fill all memory banks with identical single-rank RDIMMs to achieve maximum memory bandwidth. Registered ECC and proper population sequence guarantee computational accuracy over extended periods.
Rigorously tested server memory; compatible with Dell PowerEdge 2850, HP DL380 G4, IBM x346, and similar DDR2 ECC Registered servers.
Q: Can I mix this MT9HTF3272Y-40EB2 with other memory modules of different brands or speeds?
A: Mixing brands or speeds is not recommended for registered ECC server memory. Different timings or chip characteristics may cause instability, data corruption, or system POST failures in mission-critical environments.
Q: Is this memory compatible with my system?
A: This DDR2-400 registered ECC RDIMM is designed for legacy server platforms using Intel Xeon or AMD Opteron processors. Verify your motherboard supports 240-pin DDR2 Registered ECC memory at PC2-3200.
Q: What is the recommended DIMM population order for optimal performance?
A: For servers, populate DIMMs in the order specified by the motherboard manual, typically starting with the slots farthest from the CPU. Follow rank and channel interleaving rules to maintain balanced memory configurations.
Q: Does this module support overclocking or XMP profiles?
A: No. This module adheres to JEDEC standard DDR2-400 specifications. Server-class registered ECC memory does not support overclocking or XMP profiles; it is tuned for maximum stability and data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. As enterprise-grade registered ECC memory built for reliability, typical failure rates are exceptionally low under normal operating conditions and within specified voltage/temperature limits.
