The Samsung M393B1G70BH0 is a server-class DDR3 Registered DIMM with ECC, purpose-built for virtualization and memory-resident databases where data integrity and uptime are critical. Its single-rank configuration and registered signal architecture minimize bus loading and enhance stability, while the 1.35V low-voltage operation reduces thermal load in dense 24/7 server deployments.
1. ECC protection silently corrects single-bit errors in real time, preserving transactional accuracy and preventing silent data corruption in virtualized database clusters.
2. Registered clock driver buffers command and address signals, enabling stable multi-DIMM channel loading for dense memory configurations critical to large-scale virtualization hosts.
3. Ultra-low 1.35V operation cuts memory power draw significantly, reducing data center cooling overhead and improving energy efficiency in always-on server racks.
4. 1600MHz clock speed with PC3-12800 bandwidth provides 12.8 GB/s throughput, accelerating in-memory caching and real-time analytics under heavy query loads.
5. Single Rank organization lowers electrical loading per channel, delivering consistent, low-latency access ideal for latency-sensitive enterprise applications like high-frequency trading platforms.
The M393B1G70BH0 is a server-grade DDR3 DIMM engineered for enterprise environments where uptime and data integrity are non-negotiable. Its ECC technology actively detects and corrects single-bit memory errors, which is critical when running in-memory databases like SAP HANA or Redis. A flipped bit in a financial transaction log or a virtualization hypervisor can cascade into silent data corruption, but ECC transforms that risk into a self-healing event, protecting your business logic at the hardware level.
The module’s Registered signal type buffers the command and address lines, stabilizing the memory bus under heavy load. In a virtualized cluster running dozens of VMs on a single physical host, unbuffered memory would suffer signal degradation as DIMM population scales. This registered design lets you fully populate all memory channels without sacrificing reliability, ensuring predictable performance for dense server workloads. Combined with a low 1.35V operating voltage, the module cuts power consumption and thermal output noticeably across a rack full of nodes. Lower wattage per DIMM means reduced cooling overhead and a smaller energy bill over years of continuous operation. Finally, the DDR3-1600 speed and single-rank organization deliver consistent, low-latency bandwidth perfectly suited to frequently accessed database indexes or hypervisor memory pools, where consistent response times matter far more than peak burst rates. For a datacenter running business-critical services, these four characteristics translate directly into fewer silent errors, higher VM density, and a cooler, more cost-efficient infrastructure.
Based on the provided specifications — DDR3, ECC, Registered, 240-pin DIMM — this memory module is designed for server platforms.
General Virtualization
For virtualized hosts, a balanced capacity approach uses six to eight M393B1G70BH0 modules (48–64GB) to comfortably run multiple VMs without excessive idle memory. ECC and registered signaling guarantee stable session hosting, while populating at least one DIMM per channel maintains adequate bandwidth for concurrent workloads.
In-Memory Database
In-memory databases require maximum fault-resilient capacity. Populate all available DIMM slots with these 8GB registered ECC modules — targeting 128GB (16 DIMMs) or higher — to keep entire datasets in RAM. The strong ECC correction safeguards transactional integrity, and the registered interface enables stable operation even with fully loaded memory banks.
High-Performance Computing
HPC environments demand deterministic bandwidth and latency. Install one identical 8GB module per memory channel in each node (e.g., four DIMMs in a quad-channel server) to achieve optimal interleaving. This uniform configuration maximizes throughput for large-scale simulations and couples high-speed operation with the reliability of registered ECC memory over extended job runs.
This rigorously tested DDR3 ECC Registered DIMM works with Dell PowerEdge R620, R720, HP DL380p G8, and similar servers.
Q: Can I mix this M393B1G70BH0 with other memory modules of different brands or speeds?
A: Mixing is not recommended for Registered ECC server memory. All modules should match in speed, rank, and latency to avoid instability and ensure reliable error correction.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This DDR3-1600 ECC Registered DIMM is compatible with servers using Intel 5500/5600 series or AMD G34/C32 platforms. Always verify against your motherboard’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-socket servers, populate identical DIMMs per channel, filling blue slots first, then black. Follow the system’s memory population guide to maintain balanced interleaving and full bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. As enterprise server memory, it operates strictly at JEDEC standard DDR3-1600 with CL11. Overclocking and XMP are disabled to maintain ECC integrity and platform stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Typical annualized failure rate is well under 1% thanks to stringent EU RoHS and FCC compliance testing, ensuring long-term reliability in demanding environments.
