This Samsung M393B2G70QH0-YK008 is a 16GB DDR3L-1600 Registered ECC DIMM engineered for legacy server platforms requiring strong data integrity. Its dual-rank x4 configuration and low 1.35V operating voltage deliver consistent throughput and reduced power draw, making it well-suited for virtualized environments and memory-intensive database applications where reliability under continuous load is critical.
1. ECC protection silently corrects single-bit errors in real time, preventing data corruption that could crash critical enterprise databases or financial transactions.
2. Registered signaling buffers address and command lines, stabilizing heavy memory loads so you can pack more DIMMs per server for dense virtualization without compromising signal integrity.
3. The 16-gigabyte capacity per module provides ample headroom for mid-tier virtualized workloads, letting you run more active VMs without immediately resorting to costly scale-out.
4. 1600MHz frequency sustains 12.8 GB/s peak throughput per channel, accelerating in-memory analytics and large-page lookups under concurrent user requests.
5. Dual Rank x4 organization interleaves memory banks across two ranks, boosting sustained bandwidth and reducing access gaps that otherwise hurt consistent VM responsiveness in consolidated clusters.
The Samsung M393B2G70QH0-YK008 is a server-grade DDR3 RDIMM, engineered for mission-critical enterprise workloads where data integrity and uptime are non-negotiable. Its defining characteristics are not just specifications; they directly resolve the pain points of IT infrastructure managers.
First, the module’s ECC technology actively detects and corrects single-bit memory errors, which becomes vital when a flipped bit in a financial database or a virtualization host could corrupt transactions or crash multiple guest machines. Second, the registered signal buffer stabilizes the electrical load on the memory controller, enabling you to fully populate all DIMM slots for high-density virtualized clusters without compromising signal reliability, something unbuffered memory cannot guarantee at scale. Third, operating at just 1.35V, this low-voltage DIMM significantly reduces thermal output and energy draw across a rack of servers, translating directly into lower cooling costs and a smaller carbon footprint for large datacenters running in-memory databases like Redis. Finally, its dual-rank x4 organization enhances bank-level parallelism, delivering higher sustained bandwidth under heavy concurrent access. For an in-memory analytics platform or a heavily consolidated virtualization host, this means lower latency spikes and more predictable performance when dozens of virtual CPUs compete for memory access, keeping your service-level agreements intact.
General Virtualization
For general virtualization hosts, populate a balanced number of identical M393B2G70QH0-YK008 modules across all memory channels to ensure uniform memory access. Deploy six or eight of these 16 GB RDIMMs (96–128 GB total) to comfortably run dozens of medium-sized VMs, leaving headroom for peak loads while respecting the low 1.35 V power envelope.
In-Memory Database
In-memory databases demand maximum capacity and reliability, favoring fully populated configurations using this ECC Registered DIMM. Install 16 or more modules (256 GB+) in a dual-socket server to hold entire datasets in RAM, leveraging dual-rank x4 organization for high signal integrity under continuous heavy write operations.
High-Performance Computing
HPC workloads benefit from bandwidth-optimized population: fill all memory channels per CPU with one M393B2G70QH0-YK008 per channel to avoid rank contention while achieving peak 1600 MT/s throughput. Scale capacity by adding identical DIMMs across CPUs, keeping configurations symmetrical to prevent NUMA imbalances during parallel jobs.
Rigorously tested, compatible with Dell PowerEdge R720, R620, HP DL380p Gen8, IBM x3650 M4, and similar servers.
Q: Can I mix this M393B2G70QH0-YK008 with other memory modules of different brands or speeds?
A: Mixing is not recommended. For stable operation, all modules should match in type (DDR3 Registered ECC), rank, speed, and voltage. Mixed brands or speeds may cause boot failures or memory errors in server environments.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This is a DDR3 Registered ECC RDIMM. It requires a server motherboard with a compatible chipset and CPU supporting Registered ECC memory. Verify your board’s qualified vendor list for 16GB DDR3-1600 RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board manual for balanced memory configurations. Typically, populate identical DIMMs per channel starting from the farthest slots from the CPU. This ensures proper interleaving and keeps all memory channels active.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise-grade Registered ECC module designed for stability at JEDEC standard DDR3-1600 (PC3-12800). It does not support overclocking, XMP, or user-adjusted timing profiles.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. Annualized failure rates for server-grade RDIMMs are extremely low under normal operating conditions, typically well below 0.5% when deployed within specified thermal and voltage ranges.
