Engineered for legacy server platforms requiring Fully Buffered DIMM architecture, this 1GB DDR2-667 FB-DIMM with ECC ensures superior signal integrity and data reliability for memory-intensive workloads such as virtualization and entry-level database applications. Its dual-rank x8 configuration and CL5 latency deliver consistent performance in high-density, multi-channel configurations, while the 240-pin buffered interface reduces electrical loading for enhanced system stability.
1. Fully Buffered architecture serializes data and command paths, enabling high-density memory configurations that maintain signal integrity across numerous DIMMs for unwavering platform stability in mission-critical server deployments.
2. ECC protection continuously corrects single-bit errors and flags multi-bit faults, ensuring in-memory data integrity for financial transactions and hypervisor-managed virtual machines that cannot tolerate silent corruption.
3. Dual Rank x8 organization leverages rank interleaving to overlap read and write operations, effectively raising sustained throughput and reducing memory latency spikes under heavy consolidation of enterprise workloads.
4. One-gigabyte capacity suits lightweight container hosts or dedicated edge appliances, keeping node costs minimal while reliably powering single-function server instances.
5. PC2-5300 bandwidth provides a solid 4.2 GB/s peak transfer rate, keeping legacy line-of-business applications responsive and maintaining stable client request handling for small-office server platforms.
Judging by the FB-DIMM form factor and ECC functionality, the M395T2953CZ4-CE65 is unequivocally a server-grade memory module built for mission-critical enterprise infrastructure. Its four defining characteristics translate directly into tangible business resilience. In a dense virtualization cluster hosting a dozen virtual machines, this modules Fully Buffered architecture becomes your safeguard against silent data corruption. The advanced memory buffer on each 240-pin DIMM decouples the electrical load from the memory bus, meaning you can populate all available slots at 667MHz without signal degradation, dramatically increasing your memory capacity ceiling for VM density. The integrated ECC engine actively hunts for and corrects single-bit errors in real time. Consider an in-memory database like Redis powering a high-frequency trading dashboard: a random cosmic ray flipping a single bit in unprotected RAM could cascade into a wrong transaction worth thousands. Here, the CL5 latency and Dual Rank x8 organization ensure that error correction never chokes throughput, as interleaved access across ranks allows the memory controller to pipeline commands, hiding refresh and scrubbing latencies while sustaining the steady, reliable 1.8V data flow your financial compliance auditors demand. This isnt just memory; its insurance woven into silicon.
General Virtualization
For virtualized environments, deploy FB-DIMMs in identical pairs to utilize channel interleaving and demand ECC resilience. Install at least four M395T2953CZ4-CE65 modules (4 GB total) across both memory branches for entry-level hypervisors; scale to eight modules (8 GB) to comfortably host multiple lightweight VMs while maintaining error protection.
In-Memory Database
In-memory databases require maximum capacity and fault tolerance, so populate every available slot with these 1 GB ECC-FB-DIMMs. A fully loaded 16‑module configuration (16 GB) provides sufficient space for modest caching workloads, though the small per‑DIMM capacity mandates careful data‑set sizing. Keep all modules identical to avoid buffering latency penalties.
High-Performance Computing
HPC workloads benefit from the fully buffered bus’s high bandwidth when channels are fully populated. Install two modules per channel (e.g., eight DIMMs for four channels) to enable dual‑rank interleaving and sustain streaming memory throughput. This arrangement delivers the deterministic latency and ECC coverage necessary for parallel simulations and computational fluid dynamics codes.

Q: Can I mix this M395T2953CZ4-CE65 with other memory modules of different brands or speeds?
A: Mixing FB-DIMMs of different brands or speeds is not recommended, as it can cause signal integrity issues and instability. For optimal compatibility, use identical modules with the same part number and specifications.
Q: Is this memory compatible with my system?
A: This FB-DIMM is designed for server platforms supporting DDR2-667 Fully Buffered memory, typically with Intel 5000/5100/5400 chipsets or AMD platforms with FB-DIMM support. Verify your server board's memory compatibility list.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-rank FB-DIMMs, populate memory slots in pairs per memory branch, following your server's manual. Generally, fill the first slots of each channel symmetrically to enable interleaving and maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-standard server memory module without overclocking features. It operates at fixed timings and voltage for maximum reliability in enterprise environments. XMP is not supported.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a one-year warranty. As an enterprise-grade FB-DIMM with ECC, it has a very low failure rate under specified conditions, ensuring stable 24/7 operation.
