This Samsung M393B2G70DB0-CK0Q2 is a server-grade DDR3-1600 Registered ECC DIMM, ideally suited for virtualization platforms and memory-intensive database servers where data integrity and system uptime are non-negotiable. Its dual-rank x4 configuration with registered signaling ensures stable operation at full population, while integrated ECC effectively corrects single-bit errors to prevent silent data corruption in high-availability environments.
1. 16GB capacity per module increases memory headroom for virtualized environments, allowing more active VMs per host without resorting to costly server expansion.
2. ECC error correction automatically remedies single-bit memory faults, preserving data integrity in financial transactions and 24/7 database operations.
3. Registered signal buffering stabilizes control signals across fully populated memory channels, enabling dependable operation in multi-socket servers under sustained load.
4. Dual Rank x4 organization keeps memory bandwidth fully engaged through interleaving, reducing latency spikes during high-concurrency enterprise application processing.
5. 1600MHz speed delivers consistent 12.8 GB/s throughput per channel, efficiently supporting real-time analytics and low-latency caching workloads.
The M393B2G70DB0-CK0Q2 is a server Registered ECC DDR3 RDIMM. Its four key attributes—ECC, registered buffering, dual-rank x4, and 1600 MHz speed—directly answer real data-center concerns. In a virtualized cluster, a bit flip silently corrupts multiple VMs; on-die ECC corrects it on the fly, preventing silent data corruption and unplanned outages. The registered buffer re-drives address/command signals, letting you populate every DIMM slot with 16 GB modules without signal degradation, which is critical for maximizing memory density and ROI. Dual-rank x4 bank interleaving dramatically accelerates random access, giving in-memory databases like Redis and SAP HANA the fast scattered data fetches they require for low-latency queries. The 1600 MHz frequency, tuned to CL11, delivers the bandwidth for live migration and concurrent workloads while keeping power and thermals under control in 1U chassis. For your IT operations, this means hardened data integrity, maximized memory footprints, and predictable performance under heavy consolidation.
General Virtualization
Populate all memory channels identically to maximize throughput for multi-VM workloads. For a typical dual-socket server with four channels per CPU, install at least eight 16 GB RDIMMs (128 GB total) to run dozens of moderate VMs. Scale to sixteen modules (256 GB) when hosting memory-intensive applications or more virtual machines.
In-Memory Database
Fill every DIMM slot with 16 GB registered ECC modules to keep entire datasets in RAM. A fully loaded 24-slot server delivers 384 GB, minimizing swapping and query latency. Use identical dual-rank x4 DIMMs across all banks to ensure consistent performance and stability under sustained write pressure.
High Performance Computing (HPC)
Configure one RDIMM per channel initially to sustain the full 1600 MT/s speed without frequency drops. Eight modules (128 GB) across two processors supply ample bandwidth for simulation codes while registered ECC guards large runtimes against data corruption. Expand to two DIMMs per channel only if capacity demands exceed the bandwidth-first layout, expecting potential speed reductions to 1333 MT/s.
Rigorously tested server memory: compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, IBM System x3650 M4.
Q: Can I mix this M393B2G70DB0-CK0Q2 with other memory modules of different brands or speeds?
A: Mixing is not recommended. This registered ECC RDIMM requires identical timings and rank. Disparate modules may cause POST failures or degrade error correction, jeopardizing server stability.
Q: Is this memory compatible with my server platform, such as Intel Xeon E5 or AMD Opteron systems?
A: It is compatible with dual-processor platforms supporting DDR3-1600 registered ECC memory, including Intel Xeon E5-2600 v1/v2 and AMD Opteron 6300 series. Verify board qualification lists for specific BIOS support.
Q: What is the recommended DIMM population order for optimal performance on a dual-socket server board?
A: Populate within each memory channel following the farthest slot first, typically slot 1 then 2. Balance identical DIMMs per channel and socket to enable symmetric interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered DIMM with fixed JEDEC timings at CL11. Overclocking and XMP are unsupported, as deterministic reliability and ECC functionality take precedence over frequency tuning.
Q: What warranty and typical failure rate can I expect for this Samsung RDIMM?
A: It includes a one-year warranty. Samsung server DRAM demonstrates an annualized failure rate well below 0.5% under proper thermal and voltage conditions, ensuring excellent field longevity.
