The M395T5663QZ4-CE65 is a server-grade FB-DIMM leveraging ECC and fully buffered signaling to ensure data integrity and signal stability in dense, multi-slot configurations. Its dual-rank x8 organization with CL5 latency makes it well-suited for virtualization platforms and memory-intensive workloads, where reliable throughput and error correction are critical.
1. Fully-buffered architecture offloads memory control signaling to an AMB, vastly improving signal integrity and enabling large-scale memory populations in mission-critical servers.
2. On-the-fly error correction safeguards transactional data integrity, virtually eliminating silent data corruption in financial or database workloads.
3. Serial point-to-point connectivity isolates DRAM from the memory bus, allowing dense multi-module configurations without degrading electrical stability—essential for high-availability platforms.
4. Dual-rank interleaving increases effective memory bandwidth by overlapping activate and precharge operations, accelerating data access for concurrent virtualized workloads.
5. Delivers a balanced capacity building block that maximizes host server memory footprint within a modest power envelope, supporting higher VM density in legacy consolidation scenarios.
The M395T5663QZ4-CE65 is a server-grade Fully Buffered DIMM engineered for mission-critical enterprise environments where reliability and throughput are non-negotiable. Its ECC capability actively corrects single-bit memory errors, a must-have for in-memory databases like financial transaction ledgers; a single undetected bit flip could corrupt balance sheets or crash a trading system. The Fully Buffered architecture uses an Advanced Memory Buffer to decouple the memory bus from the DIMMs, enabling you to populate heavy virtualized clusters with more memory channels and higher capacities without signal degradation—essential when hosting dozens of virtual machines on a single hypervisor. Furthermore, its Dual Rank design leverages rank interleaving to overlap read and write cycles, effectively accelerating data retrieval for frequently accessed database indexes. Paired with a proven DDR2-667 speed and CL5 latency at a stable 1.8V, this module delivers deterministic response times during peak virtualized workloads. For IT operators, this means safeguarding data integrity, maximizing consolidation ratios, and preventing silent corruption that could otherwise propagate across replicated VMs and lead to compliance risks.
General Virtualization
Virtualized environments running multiple VMs rely heavily on memory capacity and reliability. For a server with these 2GB FB-DIMMs, aim to populate all memory channels symmetrically to maximize bandwidth under moderate overcommitment. A configuration of 8 identical modules (16GB total) can support a small cluster of light VMs, while 16 modules (32GB) expands headroom for additional guest operating systems. ECC is essential here to prevent silent data corruption during live migrations.
In-Memory Database
In-memory databases demand low latency and absolute data integrity, making ECC FB-DIMMs the right choice even for older platforms. Prioritize capacity over peak frequency: install the maximum number of supported modules—typically 16 or 32 sticks—to reach 32GB–64GB. This allows larger datasets to reside entirely in RAM, minimizing disk I/O. Fully Buffered architecture ensures stable signals across many DIMMs, safeguarding transactional consistency.
High-Performance Computing (HPC)
HPC workloads such as computational fluid dynamics or financial modeling require fast, continuous memory access and protection against soft errors. Populate four or eight identical 2GB FB-DIMMs to unlock quad-channel or dual-branch interleaving, boosting throughput for floating-point operations. Scaling to 32GB or 64GB with dual-rank x8 modules helps keep all compute cores fed, while ECC reduces checkpointing needs caused by memory faults in long-running parallel jobs.
Validated for servers: rigorously tested, compatible with Dell PowerEdge 2950/1950, HP ProLiant DL380 G5, and similar FB-DIMM platforms.
Q: Can I mix this M395T5663QZ4-CE65 with other memory modules of different brands or speeds?
A: Mixing FB-DIMMs with different brands or speeds is not recommended. The server's memory controller may downclock all modules to the slowest common speed, risking stability. Use identical, validated modules for guaranteed ECC and Fully Buffered performance.
Q: Is this memory compatible with my system?
A: This DDR2-667 FB-DIMM with ECC targets server platforms using Intel 5000 series or similar chipsets. Please verify your server board supports 240-pin Fully Buffered DDR2 and dual-rank x8 organization before purchasing.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-rank FB-DIMMs on a dual-processor server, populate identical modules in matched sets per memory branch, typically filling the first slot of each channel to maximize interleaving and bandwidth. Consult your system manual for branch-specific ordering.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-class ECC FB-DIMM operating at standard JEDEC DDR2-667 speeds (PC2-5300). Overclocking and XMP profiles are not supported, as server memory prioritizes data integrity and stability under sustained workloads.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise DDR2 FB-DIMMs typically exhibit very low failure rates under proper operating conditions when used within specified voltage and thermal limits in validated server systems.
