Designed as a registered server memory module with ECC, this 8GB DDR3-1600 RDIMM ensures data integrity and signal stability for critical workloads like virtualization and in-memory databases. Its dual-rank x8 configuration and low 1.35V operating voltage improve memory interleaving efficiency and reduce power consumption in dense rack deployments.
1. Registered command and address buffering preserves signal integrity across fully populated channels, eliminating the risk of memory errors in high-availability server architectures.
2. ECC error correction silently detects and corrects single-bit faults, ensuring uncorrupted data for financial ledgers and always-on enterprise databases.
3. DDR3L low-voltage operation cuts thermal output and power draw, helping dense rack deployments stay within cooling budgets without compromising stability.
4. Dual-rank organization enables rank interleaving that maximizes channel utilization, delivering consistent throughput under mixed virtualization workloads.
5. Mainstream DDR3 frequency supplies dependable bandwidth for caching and web-serving tiers, matching the steady throughput demands of scale-out server farms.
The Samsung M393B1G73QH0-YK0 is an 8GB DDR3L RDIMM purpose-built for enterprise servers, combining four critical characteristics that directly safeguard uptime and performance. In a virtualized cluster hosting dozens of VMs, its ECC protection silently corrects single-bit errors caused by cosmic radiation, preventing silent data corruption that could crash hypervisors or corrupt transactional records. The registered signal buffer allows you to populate multiple DIMMs per channel without signal degradation, delivering the rock‑solid stability required by memory‑hungry in‑memory databases like Redis or SAP HANA where unexpected crashes translate into revenue loss. Its dual‑rank x8 architecture boosts bank interleaving, yielding higher sustained bandwidth and lower latency under heavy concurrent accesses—exactly what virtualization paging and complex database joins demand, directly increasing query throughput and VM responsiveness. Finally, the 1.35V low‑voltage operation dramatically reduces power draw and cooling costs across your server farm, lowering total cost of ownership without compromising the 1600MT/s speed. This RDIMM keeps mission‑critical workloads consistent, efficient, and economically viable at scale.
This 8 GB DDR3-1600 Registered ECC DIMM is a server‑grade module built for reliable, high‑density deployments. Below are capacity planning recommendations for typical server workloads.
General Virtualization
Populate all memory channels with identical modules—four sticks offer 32 GB of balanced bandwidth for multiple VMs. ECC safeguards data integrity, and the 1.35 V low‑voltage design helps reduce power and cooling costs in dense hypervisor hosts.
In‑Memory Database
Maximise capacity by filling every available DIMM slot; configurations like eight modules (64 GB) keep entire datasets in RAM. Dual‑rank x8 construction improves bank‑level parallelism, while registered ECC signalling delivers the reliability demanded by transactional consistency.
High‑Performance Computing
For peak memory throughput, install one 8 GB RDIMM per channel to sustain the full 1600 MT/s speed. When greater capacity is required, use a matched pair per channel but expect slight frequency de‑rating. The registered interface supports stable large‑scale clusters, and the 1.35 V profile suits energy‑conscious HPC deployments.
This server DDR3 RDIMM is rigorously tested and compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M393B1G73QH0-YK0 with other memory modules of different brands or speeds?
A: Mixing registered server DIMMs is strongly discouraged. Mismatched brands or speeds often cause signal integrity issues and system instability. For guaranteed reliability, use identical Samsung M393B1G73QH0-YK0 modules with the same rank, voltage, and CAS latency.
Q: Is this memory compatible with my system?
A: This is a DDR3-1600 ECC Registered RDIMM operating at 1.35V. It is compatible with Intel Xeon E5-2600 v2 and AMD Opteron 6300 series platforms. Always confirm your server board's QVL supports 8GB dual-rank x8 RDIMMs before purchasing.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server board manual for exact population rules. Typically, install equal dual-rank DIMMs per channel, filling the first slot of each memory channel (often the blue slots) first to enable balanced interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise ECC Registered DIMM built to strict JEDEC DDR3-1600 specifications. It does not support XMP or overclocking. Its design priority is data integrity and 24/7 stability, not performance tuning.
Q: What warranty and typical failure rate can I expect?
A: This Samsung module carries a 1-year warranty. The failure rate is exceptionally low, typically below 0.2% annually, thanks to rigorous wafer-level screening and BGA testing, reflecting its proven enterprise-grade reliability.
