Designed for legacy server platforms, this Samsung M393T2950EZA-CE6 is a 1GB DDR2-667 Registered ECC DIMM (PC2-5300) that ensures data integrity in mission-critical environments through error-correcting code and registered signal buffering. Its single-rank x4 configuration and CL5 latency deliver stable, predictable performance ideal for small-scale virtualization hosts, lightweight database servers, or embedded appliances where memory reliability takes priority over capacity.
1. DDR2 memory technology provides proven reliability and wide compatibility with legacy server platforms, ensuring seamless integration into existing data center infrastructure.
2. A single-gigabyte capacity offers a cost-optimized building block for light-duty virtualized services, balancing resource allocation with energy efficiency.
3. ECC protection detects and corrects single-bit errors in real time, preserving data integrity for mission-critical enterprise applications.
4. Registered signal buffering stabilizes high-density memory configurations, reducing electrical load on the memory controller for improved system uptime.
5. 667 MHz speed delivers consistent memory bandwidth, sustaining steady application throughput under typical server workloads without bottlenecks.
The M393T2950EZA-CE6 is a server-grade Registered DIMM built on DDR2 technology, and its four defining characteristics directly address the critical pain points of legacy data centers that simply cannot tolerate unplanned downtime. Its ECC engine works silently to detect and correct single-bit errors caused by cosmic radiation or electrical noise, which is non-negotiable for a memory-resident database like SAP HANA—a flipped bit in an in-memory index is not a nuisance, it’s a corrupted financial record. The registered signal buffer re-drives address and command lines through an on-board register, stabilizing the heavy bus loading when you fully populate a 16-slot server board. Without this, a virtualization cluster hosting dozens of VMs would suffer intermittent boot failures or kernel panics as signal integrity collapses under the sheer number of DIMMs. Furthermore, the Single Rank x4 organization presents a lighter electrical load per channel compared to dual-rank alternatives, allowing your hypervisor to allocate reliable, predictable bandwidth to each virtual machine under concurrent I/O bursts. The 667 MT/s speed coupled with CL5 latency strikes the exact balance that routine transactional processing expects, ensuring your end-of-life but business-critical asset keeps serving with unwavering integrity.
The Samsung M393T2950EZA-CE6 is a 1GB DDR2-667 ECC Registered RDIMM intended for legacy server platforms.
General Virtualization
Populate all memory channels evenly with these modules; on a typical dual-socket legacy system that means 8–12 DIMMs, yielding 8–12 GB total. This supports only a handful of lightweight test VMs. Any production virtualization demands modern high-capacity RDIMMs.
In-Memory Database
An in-memory database requires large datasets, and a 1GB DIMM is severely limiting. Maximize installed modules across all channels to reach the highest possible capacity and enable interleaving. Even then, you get just a few gigabytes, suitable only for miniature proof-of-concept trials but unacceptable for real workloads.
High-Performance Computing (HPC)
For HPC, memory bandwidth is critical: install one DIMM per channel to achieve balanced interleaving and full channel utilization. Older servers often need 8 or 16 identical modules for symmetric population. While total capacity is low, this configuration extracts the best possible throughput from the DDR2-667 interface and leverages ECC reliability for legacy computational kernels.

Q: Can I mix this M393T2950EZA-CE6 with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. Registered ECC modules must be installed in identical configurations. Different brands, speeds, or ranks can lead to signal integrity issues, system instability, and corrected errors.
Q: Is this memory compatible with my Intel or AMD server platform?
A: It is compatible with servers using DDR2 Registered ECC RDIMMs, such as Intel 5000/5100/5400 chipset boards or equivalent AMD Opteron platforms with 240-pin sockets. Verify your board supports 667MHz RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate modules in matched pairs across memory channels per your server manual. Typically, install in the slots farthest from the CPU first, then fill subsequent channels to maintain balanced interleaving and full bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this module does not support overclocking or XMP. It operates at JEDEC standard DDR2-667 timing parameters to guarantee maximum data integrity and 24/7 reliability in mission-critical server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. As a server-grade component built with industry-standard specifications and conservative timings, the typical annualized failure rate is well below 0.5% under normal operating conditions.
