This is an entry-level server/workstation memory module featuring ECC (Error-Correcting Code) on an unbuffered UDIMM design, tailored for single-socket servers or workstations running light virtualization, file services, or data-critical applications where data integrity is paramount. Its dual-rank x8 organization with 8 GB capacity enhances memory interleaving and bandwidth utilization within the 1.5V DDR3-1600 envelope, delivering reliable, error-resistant performance at CL11 latency.
1. ECC actively corrects single-bit memory faults on the fly, preserving data integrity for always-on servers where silent corruption cannot be tolerated.
2. The module’s capacity per stick supplies sufficient headroom for consolidating several lightweight virtual machines, boosting tenant density in entry-level virtualization hosts.
3. The high clock speed translates directly into available per-channel throughput, allowing concurrent backup or caching jobs to complete without creating a memory bottleneck.
4. Dual rank organization interleaves internal banks to keep command pipelines full, critical for sustaining consistent IOPS when a storage server fields simultaneous small-block reads.
5. Unbuffered signaling eliminates the register delay inherent in registered DIMMs, delivering lower absolute latency for trading or microservices platforms that prize every microsecond.
Engineered for entry-level servers and small business workstations, the Micron MT18JSF1G72AZ-1G6E1 is an 8GB DDR3-1600 Unbuffered ECC UDIMM that directly addresses the real cost of memory errors: unscheduled downtime and data corruption. Running a virtualized cluster with several lightweight guests on a single host? A single bit flip in hypervisor memory can silently crash multiple services or corrupt a critical log. The module’s true ECC protection continuously detects and corrects single-bit errors, transforming random cosmic-ray events from potential disasters into transparent, non-events—this means your customers experience consistent uptime rather than mysterious, unreproducible failures.
When deployed as a memory-resident database cache or a fast in-memory analytics tier, responsiveness is non-negotiable. The dual-rank x8 organization with a 1600MHz clock and CL11 latency maximizes memory bandwidth utilization through rank interleaving, allowing the memory controller to pipeline commands between ranks and reduce effective wait states. For a busy database like Redis or a read-heavy MySQL server, that translates directly into more queries per second and snappier dashboard refreshes—turning raw specs into tangible productivity gains without requiring registered memory’s extra cost and latency overhead. In a 240-pin UDIMM form factor with 1.5V standard voltage, it slots neatly into cost-conscious platforms where reliability must never be compromised.
Capacity Planning Guide for 8GB DDR3-1600 ECC Unbuffered DIMMs
This module is an unbuffered ECC UDIMM, intended for entry-level servers and workstations that require error correction without registered memory. Below are recommendations for three common workloads.
General Virtualization
Install four 8GB modules (32 GB total) in dual-channel interleaved mode for a hypervisor hosting 5–10 light VMs. ECC guards against memory errors that could destabilize guests. Reserve at least 20% headroom for hypervisor overhead and burst loads.
In‑Memory Database
Use four modules (32 GB) for modest Redis or Memcached instances, or eight modules (64 GB) on boards with four memory channels. ECC is essential to preserve data integrity in memory‑resident stores. Provision 25% extra RAM beyond your dataset for replication buffers and OS operations.
High‑Performance Computing
Populate all memory channels evenly in dual‑socket nodes—typically 8 to 16 modules (64–128 GB). The dual‑rank x8 design supplies ample bandwidth for simulation codes. ECC prevents silent corruption during multi‑day runs. Balance memory per core to match the CPU’s floating‑point throughput.
Tested server-grade ECC UDIMM, compatible with Dell PowerEdge T110 II, HP MicroServer Gen8, Lenovo ThinkServer TS140.
Q: Can I mix this MT18JSF1G72AZ-1G6E1 with other memory modules of different brands or speeds?
A: Mixing is not recommended. In server environments, mismatched modules can compromise signal integrity and lead to data corruption or POST issues. Always deploy identical DIMMs for guaranteed stability.
Q: Is this memory compatible with my system?
A: This ECC unbuffered DIMM is validated for Intel Xeon E3-1200 v2/v3 platforms and select AMD AM3+ motherboards with DDR3 ECC UDIMM support. Verify your system requires 240-pin DDR3-1600 ECC DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Install in matched pairs or quads, starting with the primary slots (often blue) per channel. Follow your server motherboard manual for dual-channel configuration to achieve balanced memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade module built to JEDEC DDR3-1600 CL11 standards. It prioritizes data reliability over overclocking and does not include XMP profiles.
Q: What warranty and typical failure rate can I expect?
A: Backed by a one-year warranty. It undergoes rigorous factory testing to maintain an extremely low AFR, making it suitable for continuous operation in business-critical environments.
