Ideal for legacy server platforms running virtualization or in-memory databases, this 8 GB DDR3-1333 Registered DIMM ensures critical data integrity with hardware ECC and stable signal distribution under heavy load. Its dual-rank x4 organization combined with CL9 latency effectively balances capacity and access speed, making it a reliable upgrade for aging enterprise systems that require consistent uptime and error resilience.
1. Registered DIMM architecture buffers command and address signals, sustaining signal integrity in fully loaded server nodes for uninterrupted operation of mission-critical applications.
2. ECC error correction detects and repairs single-bit memory faults in real time, safeguarding data accuracy during prolonged database transactions and financial computations.
3. Dual Rank x4 organization interleaves memory accesses across ranks, maximizing channel utilization to keep data flowing smoothly under heavy virtualization workloads.
4. Registered signal type decouples electrical loads from the memory controller, enabling dense module populations that enhance overall system memory bandwidth for large-scale in-memory processing.
5. Eight-gigabyte capacity per stick provides a fine-grained building block, allowing IT architects to right-size memory footprints for containers and microservices without overspending on idle resources.
When your data center runs virtualized clusters or an in-memory database like SAP HANA, the memory module you choose becomes the foundation of uptime and performance. The Samsung M393B1K70DH0-CH908 is an 8GB DDR3-1333 RDIMM, engineered specifically for server workloads where failure is not an option. Its ECC technology silently detects and corrects single-bit errors, preventing the silent data corruption that can crash a hypervisor hosting dozens of virtual machines. Because it is a Registered DIMM, the on-board buffer stabilizes electrical signals, allowing you to populate all 24 slots on a dual-socket board without compromising signal integrity—critical when you need to scale to 192GB or more for dense consolidation. The module’s dual-rank x4 organization enables effective rank interleaving, boosting bandwidth utilization during mixed workloads, so your Redis instance serves peak queries with measurably lower latency. And with CL9 latency at 1333MHz, it delivers deterministic response times under the constant read-write pressure of a financial trading database. This isn’t just memory; it’s a deliberate choice to keep your enterprise infrastructure predictable, resilient, and performing exactly when it matters most.
The memory module M393B1K70DH0-CH908 is a server‑grade DDR3‑1333 Registered ECC DIMM with a dual‑rank x4 organization. It is designed for multi‑socket server platforms that require data integrity and large memory footprints. Capacity planning should align with workload characteristics.
General Virtualization
For a dual‑socket server with four memory channels per CPU, populate each channel symmetrically with one 8 GB module to obtain 64 GB total, providing balanced throughput for a dozen light VMs. For heavier consolidation, install two modules per channel (16 × 8 GB = 128 GB) while keeping identical ranks in each channel to avoid latency jumps.
In‑Memory Database
Maximise capacity by filling every available DIMM slot with the identical dual‑rank 8 GB RDIMM. In a 24‑slot system this yields 192 GB, enough to hold large working sets entirely in RAM. Configure the memory to run at 1333 MHz and enable NUMA interleaving so that hot datasets remain local to each processor.
High‑Performance Computing
Prioritise bandwidth over raw capacity. Install exactly one 8 GB DIMM per memory channel – for example eight modules in an eight‑channel platform (64 GB total) – to operate at the highest rated speed without clock throttling. The native dual‑rank organisation per channel helps sustain steady high throughput for compute‑intensive workloads.
Rigorously tested server memory, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, Lenovo ThinkSystem RD630, and more.
Q: Can I mix this M393B1K70DH0-CH908 with other memory modules of different brands or speeds?
A: Mixing is not recommended. Server platforms require strict uniformity. Different brands or speeds may cause stability issues, prevent proper ECC operation, or lead to POST failure. Use identical Samsung modules to ensure reliability.
Q: Is this memory compatible with my system?
A: This 8GB DDR3-1333 RDIMM with ECC is designed for servers. It suits Intel Xeon E5-2600/E5-2400 series and AMD Opteron 6300 platforms. Please verify your motherboard's QVL for DDR3 Registered DIMM support to confirm compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: To maximize memory bandwidth, populate identical DIMMs per channel. For dual-socket servers, refer to your motherboard manual: typically fill slots A1, B1, C1, D1 first, then corresponding second slots. Balanced configuration ensures optimal interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No, this registered ECC server memory does not support overclocking or XMP profiles. It operates strictly at JEDEC standard DDR3-1333 with CL9 timing to guarantee data integrity and compatibility in mission-critical server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Samsung server DRAM exhibits a typical AFR well below 1%, backed by rigorous testing. Failures are rare under normal operating conditions, ensuring high reliability for enterprise workloads.
