Designed for legacy server platforms, this FB-DIMM with ECC and a Fully Buffered signal type ensures robust data integrity and stable operation in memory-intensive workloads such as virtualization and in-memory databases. Its Dual Rank x4 organization and CL5 latency work together to deliver reliable throughput, while the 240-pin form factor and 1.8 V power profile make it a precise fit for older DDR2-667 enterprise systems where error correction and buffered signaling are critical.
1. End-to-end error correction actively detects and repairs bit-flips in real time, safeguarding transaction accuracy in financial databases and long-running scientific computations.
2. The fully buffered architecture decouples the memory bus electrical load, enabling reliable operation with large numbers of DIMMs per server to maximize total installed memory.
3. Dual-rank x4 memory interleaving maximizes channel utilization, delivering consistent latency and throughput when hosting multiple virtual machines on a single physical node.
4. That speed grade supplies balanced read/write responsiveness for mid-tier enterprise servers handling web services, email, and collaboration platforms.
5. A practical building-block density allows incremental memory expansion, aligning day-one investment with future growth in cloud or hosting infrastructures.
When managing a legacy server farm that still runs mission-critical virtualization clusters or in-memory databases, the Samsung M395T5750GZ4-CE66 memory module is far more than a simple upgrade—it is a safeguard against silent failure. This DDR2-667 FB-DIMM integrates ECC, which continuously corrects single-bit errors caused by background radiation. For a hypervisor hosting dozens of virtual machines, that means preventing corrupted data from crashing an entire service or causing unnoticed data drift in a transactional database. Its Fully Buffered architecture serializes command and data channels, preserving signal integrity even as you populate all slots for maximum capacity. This directly addresses the pain of memory scalability in older servers, allowing you to confidently assign more RAM to memory-hungry VMs without risking instability. The dual-rank x4 organization interleaves addresses across internal banks, raising effective bandwidth and maintaining CL5 latency under concurrent loads, so an in-memory analytics engine experiences snappier query responses. Additionally, EU RoHS and FCC compliance ensure environmentally safe operation and reduced electromagnetic interference, which translates to cleaner signals and higher availability in densely packed racks. For uptime-dependent environments, these characteristics turn a modest 2GB module into a critical pillar of reliability.
General Virtualization
FB-DIMMs with ECC are essential for virtualization hosts where data integrity is critical. For a hypervisor running multiple VMs, install at least eight identical M395T5750GZ4-CE6 modules to populate both memory channels evenly, maximizing bandwidth and capacity. Leverage the dual-rank design and fully buffered architecture to support dense VM consolidation without sacrificing stability.
In-Memory Database
In-memory databases like Redis or SAP HANA demand the lowest latency and absolute error correction. Populate all available slots with these 2GB FB-DIMMs to reach the maximum supported capacity, as the fully buffered interface reduces electrical loading on the memory bus. Configure rank interleaving in the BIOS to exploit the dual-rank x4 organization, improving transactional throughput.
High-Performance Computing
HPC workloads require sustained throughput and resilient operation during long compute runs. Install modules in balanced sets across memory risers to achieve optimal interleaving and bandwidth aggregation. The 1.8V FB-DIMMs, running at 667MHz, can be deployed in large clusters where their buffered signaling and ECC protection maintain result accuracy across hundreds of nodes.
Rigorously tested server FB-DIMM. Compatible with Dell PowerEdge 2950/2900, HP DL380 G5, IBM x3650.
Q: Can I mix this M395T5750GZ4-CE66 with other memory modules of different brands or speeds?
A: Mixing FB-DIMMs of different brands or speeds is not recommended. It may cause instability, force the memory controller to downclock to the lowest common speed, or violate server validated configurations.
Q: Is this memory compatible with my system?
A: This DDR2-667 FB-DIMM is designed for Intel 5000/5100/5400 series and AMD socket F server platforms. Please verify your motherboard’s qualified vendor list for 240-pin fully buffered support.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical dual-rank DIMMs in pairs per channel, following the server board manual's branch 0 first. Typically fill slots 1 and 3 across both branches for balanced interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No, this ECC FB-DIMM does not support overclocking or XMP. It operates strictly at JEDEC-standard DDR2-667 timings for maximum data integrity and stability in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Actual failure rates are very low under proper cooling, typically below 0.2% annually, as FB-DIMMs are built with robust ECC and stringent manufacturing standards.
