This Samsung M393B2G70CB0-CK0 is a 16GB DDR3-1600 registered ECC RDIMM engineered for legacy server platforms, delivering rock-solid data integrity for virtualization hosts and in-memory databases. Its dual-rank x4 organization and registered signal topology ensure stable operation under high-density memory configurations, while ECC protection guards against single-bit errors in mission-critical 24/7 workloads.
1. ECC protection detects and corrects single-bit memory errors on the fly, shielding virtualized financial transaction ledgers and medical databases from silent data corruption that would otherwise crash critical services.
2. Registered signal topology buffers the address and command lines, allowing the server to support dense memory populations without signal degradation, essential for maintaining stability in large-scale HPC clusters.
3. Dual Rank x4 configuration leverages rank interleaving to keep data buses active, delivering consistent low-latency throughput vital for real-time analytics engines processing simultaneous high-concurrency queries.
4. The generous per-DIMM capacity boosts overall RAM density per node, enabling higher virtual machine consolidation ratios so cloud platforms can host more tenants without sacrificing memory headroom.
5. Backed by a high clock speed, sufficient channel bandwidth is ensured to feed modern multi-core server CPUs, accelerating data movement in content delivery networks during peak traffic bursts.
The M393B2G70CB0-CK0 16GB DDR3 RDIMM addresses the four biggest reliability and performance challenges in data centers. ECC detects and fixes single-bit errors from cosmic rays instantly—in a virtualized cluster hosting financial transactions, an uncorrected bit flip would corrupt ledger data and crash a VM; ECC guarantees transactional integrity. The Registered buffer cleans command signals so you can populate all 24 DIMM slots without loading instability. This matters when you need to grow an in-memory database like Redis to hundreds of gigabytes without sacrificing uptime. Dual Rank x4 architecture leverages bank interleaving to accelerate concurrent access. During mixed workloads—say, live migration of VMs while processing thousands of OLTP queries—it sustains high throughput and avoids latency spikes that slow applications. Finally, the 1600MHz speed with CAS 11 latency balances fast response for virtual desktops with energy-conscious 1.5V operation. The result: reduced server sprawl, unwavering data accuracy, and continuous availability for mission-critical services.
Server Memory (DDR3-1600 RDIMM ECC)
This 16GB registered ECC module is designed for server-class platforms requiring data integrity and sustained uptime. Capacity planning must balance channel population, maximum supported ranks, and workload demands.
General Virtualization
Populate memory channels symmetrically to maximize bandwidth for multiple VMs. A typical dual-socket server benefits from six to eight identical 16GB RDIMMs (96–128GB total) arranged evenly across both processors. This ensures interleaved access and enough headroom for hypervisor overhead and moderate consolidation ratios.
In-Memory Database
Maximize capacity and reliability by fully populating all DIMM slots per socket while respecting rank limits. For a server supporting three DIMMs per channel, configuring eighteen 16GB dual-rank modules (288GB) delivers large working sets in RAM. ECC correction is essential to prevent silent data corruption, and dual-rank x4 organization provides a good balance of capacity and command/address bus loading.
High Performance Computing
Bandwidth-sensitive HPC workloads require one DIMM per channel for peak throughput. Populate eight channels of a dual-socket node with eight 16GB RDIMMs (128GB) to sustain 12.8 GB/s per channel at 1600MT/s. Use identical, matched modules to maintain signal timing and avoid performance penalties from unbalanced configurations.
Rigorously tested for server compatibility. Confirmed with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and Lenovo ThinkServer RD530.
Q: Can I mix this M393B2G70CB0-CK0 with other memory modules of different brands or speeds?
A: Mixing is not advised. Servers require identical ranks, timings, and speeds for stability. Mismatched modules often cause POST failures, ECC errors, or degraded performance. Always use identical DIMMs or fully validated kits.
Q: Is this memory compatible with my system?
A: This 16GB DDR3-1600 ECC Registered RDIMM targets Intel Xeon E5-2600 v2/5600 series and AMD Opteron 6300 platforms. Confirm your server board explicitly supports 1.5V, 240-pin DDR3 RDIMMs before purchasing.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with slots farthest from the CPU. For this dual-rank x4 RDIMM, fill blue slots first, then black, following your server manual for balanced memory channels and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. It runs at standard JEDEC speeds (1600MHz CL11). As a server-grade ECC Registered DIMM, it prioritizes data integrity and stability; overclocking and XMP profiles are not supported.
Q: Can I use this RDIMM in place of a UDIMM or LRDIMM?
A: No. RDIMMs use a register chip and require motherboard support. They are not interchangeable with UDIMMs or LRDIMMs. Installing an RDIMM in a UDIMM-only slot will prevent the system from booting.
