This 8GB DDR3-1600 Registered ECC RDIMM is purpose-built for legacy server platforms handling memory-intensive workloads such as virtualization and in-memory databases. Its dual-rank x4 organization combined with registered signal buffering enhances signal integrity and maximum capacity scaling, while the 1.35V low-voltage operation and ECC error correction ensure energy-efficient data integrity under continuous load.
1. ECC memory detects and corrects single-bit errors in real time, safeguarding transactional data integrity for financial databases and preventing silent corruption that could crash virtualized workloads.
2. Registered signal type buffers the command and address buses, enabling the server to support high-density memory configurations without signal degradation—crucial when scaling up RAM for large in-memory datasets.
3. Dual Rank x4 organization interleaves access across two internal rank groups, keeping server memory channels fully utilized and improving throughput under heavily consolidated virtual machine environments.
4. 1.35V low-voltage operation cuts power draw per DIMM, directly reducing energy and cooling costs across a hyperscale fleet while maintaining data-center thermal limits.
5. 1600MHz clock speed provides balanced bandwidth for concurrent request processing, helping web servers and mid-tier application servers sustain responsive latency under moderate user loads.
The Samsung M393B1K70QB0-YK008 is an 8GB DDR3 Registered ECC DIMM purpose-built for enterprise servers. Its ECC correction prevents data corruption that can crash a virtualized host running multiple VMs or produce incorrect results in a financial trading database, where a single bit-flip means lost revenue. The registered signal buffer provides the stability needed to populate all memory channels, letting you scale to hundreds of gigabytes without boot failures or instability. Operating at a low 1.35V, it slashes power consumption and cooling costs in dense data centers, directly reducing total cost of ownership. Moreover, the dual-rank x4 organization uses rank interleaving to boost effective bandwidth—essential for an in-memory database like Redis that faces massive parallel requests, where overlapped ranks cut response latency. For virtualized clusters and latency-sensitive workloads, this RDIMM delivers the data integrity, scalability, energy efficiency, and performance your infrastructure demands.
General Virtualization
For consolidated virtualization hosts, populate at least six or eight identical M393B1K70QB0-YK008 modules to achieve 48 GB or 64 GB of registered ECC memory in a balanced multi-channel configuration (typically 3 DIMMs per channel on dual-socket platforms). Distribute dual-rank x4 RDIMMs evenly across memory channels to maximize bandwidth and sustain high VM density. Spare one memory channel per processor to leave room for future scale-out without disrupting existing virtual machines.
In-Memory Database
In-memory database workloads demand both capacity and reliability, so deploy a fully symmetric population with twelve to twenty-four of these 8 GB RDIMMs for 96 GB to 192 GB total. Maintaining identical dual-rank DIMMs in every channel ensures consistent latency and avoids memory-speed downgrades that occur with mixed ranks. The registered ECC feature is critical here: it corrects single-bit errors on the fly, protecting data integrity during large cache and table scans.
High-Performance Computing
For HPC clusters, populate all memory channels with one M393B1K70QB0-YK008 per channel to achieve peak memory bandwidth under sustained floating-point and MPI workloads. The 1.35 V DDR3-1600 RDIMM at CL11 balances power and throughput; use a one-DIMM-per-channel rule to keep the memory bus at the full 1600 MT/s. When per-node capacity needs grow, move to two identical dual-rank DIMMs per channel but be aware that the memory speed may drop slightly—validate against application performance requirements.
Tested rigorously, this server RDIMM works with Dell PowerEdge R720, HP DL380p Gen8, and Lenovo RD630.
Q: Can I mix this M393B1K70QB0-YK008 with other memory modules of different brands or speeds?
A: Mixing is not recommended for server environments. This RDIMM requires identical ECC, registered DDR3 specifications to avoid memory errors or system instability. Any mixed speed falls back to the slowest module's profile.
Q: Is this memory compatible with my system?
A: This DDR3-1600 registered DIMM supports Intel Xeon E5/E5 v2 and AMD Opteron G34/C32 server platforms using the C600/C602 chipset. Verify your motherboard accepts 1.35V, 8GB DR x4 ECC RDIMMs before ordering.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel following your server board's silkscreen order, typically slot 1 first. Leverage all memory channels evenly with matching dual-rank DIMMs to maximize throughput and maintain balanced memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a registered ECC server memory, it strictly adheres to JEDEC DDR3-1600 (PC3-12800) standards. Overclocking and XMP are disabled to guarantee data integrity in mission-critical 24/7 deployments.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty covering defects. Enterprise RDIMMs like this exhibit very low failure rates (below 1% per annum) when operated within specified voltage and thermal parameters in certified server platforms.
