This 1GB DDR-266 (PC-2100) Registered ECC RDIMM is engineered for legacy server platforms running virtualization or memory-resident databases where data integrity is non-negotiable. The Registered signaling and Single Rank x4 architecture minimize bus loading to maintain stable, error-corrected operation under fully populated configurations, while the CL2.5 latency ensures responsive access for critical workloads.
1. 1GB capacity establishes a reliable memory baseline for dedicated network and security appliances, where static allocation ensures deterministic service delivery under constant packet loads.
2. 266MHz clock speed delivers 2.1GB/s peak bandwidth, sustaining line-rate data processing in small-form-factor edge servers and content caching nodes.
3. ECC protection transparently corrects single-bit errors, safeguarding transactional databases and financial logging systems from silent data corruption.
4. Registered logic buffers control signals to maintain signal integrity across fully populated memory channels, unlocking the high capacity density demanded by consolidated virtualization hosts.
5. Single Rank x4 organization leverages narrow-interface DRAMs to strengthen Chipkill-level error correction, maximizing uptime for mission-critical enterprise applications.
The Samsung M312L2828DT0-CB0Q0 is a server-grade DDR-266 Registered DIMM, and its four defining characteristics directly address the unforgiving demands of enterprise infrastructure. In a virtualization cluster running dozens of VMs on a single host, signal integrity becomes the limiting factor as you populate all memory channels. The registered architecture places a buffer between the memory controller and the DRAM chips, stabilizing the electrical load so you can scale to higher capacities without random crashes or boot failures—this means dense consolidation stays reliable under heavy memory pressure. Equally critical is ECC, which actively corrects single-bit errors before they cascade into silent data corruption that could crash a financial transaction database or corrupt a live analytics batch. The single-rank x4 organization strengthens this further; x4-based DIMMs subject each data word to a wider ECC net, dramatically improving the module’s ability to detect and correct multi-bit faults compared to x8 layouts, an essential safeguard for in-memory databases like Redis or SAP HANA where every bit must be trusted. Finally, the tight CL2.5 latency at 266 MHz ensures that database queries and virtualized workloads see faster access times, reducing CPU stalls and keeping response times predictable even as capacity grows. This memory doesn’t just store data—it preserves the integrity and responsiveness your business runs on.
Memory Type Identification
The module M312L2828DT0-CB0Q0 is a DDR-266 (PC-2100) Registered ECC RDIMM with 1 GB capacity, 184-pin form factor, and 2.5V operating voltage. These characteristics—Registered ECC, 184-pin, and 2.5V—definitively classify it as server-grade memory for legacy DDR1 platforms.
General Virtualization
Virtualized hosts demand both capacity and reliability. With only 1 GB per module, achieving a viable baseline of 8–16 GB requires populating 8 to 16 identical RDIMM slots across all memory channels. Always install modules in identical pairs to maintain balanced interleaving and ECC protection. For light hypervisor workloads, a minimum of four modules (4 GB) can function, but performance rapidly degrades under memory overcommitment unless substantially more modules are added.
In-Memory Database
In-memory databases benefit from maximum capacity and low latency. Plan to fully populate every available DIMM slot with these 1 GB RDIMMs to extract the highest possible capacity a legacy server can offer. Because CAS latency is CL2.5, these modules deliver relatively fast access for their era. Even with a fully loaded 16-slot board (16 GB), dataset size must be strictly limited; pair with fast storage to offload spillover.
High-Performance Computing (HPC)
HPC applications require both bandwidth and ECC data integrity. Install modules in matched ranks across all memory channels to maximize throughput—typically six or eight identical RDIMMs in a dual- or quad-channel configuration. Single-rank x4 organization helps reduce electrical loading, allowing a higher number of modules to coexist at full speed (266 MHz). Avoid mixing ranks or capacities to prevent the memory controller from downshifting to a slower, non-optimized mode.

Q: Can I mix this M312L2828DT0-CB0Q0 with other memory modules of different brands or speeds?
A: Mixing Registered ECC modules with different brands or speeds is not recommended. Inconsistent timings and loading can cause system instability on server platforms. For guaranteed reliability, populate with identical part numbers.
Q: Is this memory compatible with my system?
A: This is a 1GB DDR-266 Registered ECC RDIMM (184-pin, 2.5V). It is compatible with older server platforms using Intel E7500/E7520 chipsets or select AMD Opteron boards that explicitly require PC2100R registered memory. Verify your motherboard's qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: For servers, always follow the memory population guidelines in your system manual. Typically, Registered DIMMs must be installed in matched pairs per bank, starting with the slots furthest from the processor to maintain signal integrity.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade Registered ECC module adhering strictly to JEDEC DDR-266 standards. It does not support overclocking or XMP profiles, as operational stability and data integrity are the primary design goals.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a 1-year warranty. Server-grade ECC memory is manufactured to stringent quality standards, resulting in a very low annualized failure rate (AFR) under normal operating conditions.
