The M393B4G70DM0-YH93Q is a 32GB DDR3-1333 registered ECC RDIMM with a quad-rank x4 organization, making it purpose-built for legacy server platforms that demand high memory density and data integrity. Its 1.35V low-voltage operation combined with ECC and registered signaling ensures stable, energy-efficient performance in virtualized environments, memory-intensive databases, and mission-critical workloads where reliability is paramount.
1. Generous memory footprint allows a single server node to host significantly more virtual machines and containers, directly boosting consolidation ratios in virtualized datacenters.
2. Error-correcting code support intercepts and corrects single-bit memory faults in real time, preventing silent data corruption that could crash critical databases or transactions.
3. Registered logic on the module buffers command and address signals, preserving signal integrity when populating all channels for maximum server memory capacity.
4. Quad-rank x4 organization packs higher density per DIMM while maintaining stable electrical loading, letting infrastructure workloads run reliably even under sustained full-memory access.
5. 1.35V low-voltage operation reduces power draw and thermal output across a rack full of servers, cutting cooling costs without sacrificing availability in always-on deployments.
The Samsung M393B4G70DM0-YH93Q, a 32GB DDR3L RDIMM, is vital for enterprise servers due to four features: ECC, registered buffering, quad-rank density, and 1.35V low voltage. In a virtualization cluster, ECC corrects single-bit errors caused by cosmic radiation, preventing silent data corruption that could crash VMs or compromise transactional databases. Registered buffering stabilizes command/address signals, allowing you to populate all memory channels for the terabyte-scale capacity that in-memory databases like Redis and SAP HANA demand. The quad-rank x4 build achieves 32GB per stick, maximizing memory per slot so entire datasets reside in RAM without wasting DIMM slots. The 1.35V operation reduces power consumption by roughly 20% versus 1.5V DDR3, lowering thermal stress and energy bills in always-on datacenters. This means your virtualized workloads remain safe and responsive, your real-time analytics run faster, and your total cost of ownership drops—an essential platform for consolidation and big-data applications.
General Virtualization
For dense virtualization hosts, this 32GB DDR3-1333 RDIMM allows cost-effective scaling to 256–512GB per server using 8 to 16 modules in a dual-socket configuration. Deploy modules in balanced sets across memory channels (e.g., 16×32GB for 512GB) to sustain consistent VM density and avoid NUMA bottlenecks under mixed workloads.
In-Memory Database
Quad-rank x4 registered DIMMs deliver high capacity per slot, making them ideal for building a 384–768GB memory pool (12–24 modules) for Redis or SAP HANA test environments. Populate all channels identically with three DIMMs per channel to maximize bandwidth while taking advantage of 1.35V low-voltage operation to reduce cooling overhead during sustained in-memory analytics.
High Performance Computing
When retrofitting legacy HPC nodes, install 8 or 12 modules (256–384GB) to provide sufficient headroom for large matrix manipulations or burst-buffer staging. Configure uniform four- or six-module groups per processor to maintain triple-channel efficiency, and use the ECC capability to protect long-running simulations against single-bit errors in registered memory paths.
Rigorously tested server memory, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M393B4G70DM0-YH93Q with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged for registered ECC memory. Combine only identical modules with the same part number, rank, and speed to avoid system instability or POST failures on server platforms.
Q: Is this memory compatible with my system?
A: It is designed for servers supporting DDR3 registered ECC RDIMMs, such as Intel Xeon E5-2600 v1/v2 or AMD Opteron 6300 series. Always verify your motherboard's QVL for compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board manual. Typically, populate identical DIMMs starting from each channel’s first slot (DIMM A1/B1) to enable balanced interleaving and maximize memory bandwidth with this quad-rank module.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-class registered DIMM, it adheres strictly to JEDEC DDR3-1333 standards for reliability. Overclocking and XMP are not supported; the module runs at its native 1333 MHz speed.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Enterprise-grade components ensure a very low failure rate with high MTBF. We perform rigorous testing to deliver stable, long-life operation in 24/7 environments.
