This UDIMM with ECC is an unbuffered DDR3-1866 module tailored for entry-level servers and workstations that demand data integrity without the cost of registered memory. Its dual-rank x8 organization and tight CL13 latency deliver reliable throughput and efficient interleaving, making it an excellent fit for small business servers, NAS appliances, and memory-sensitive professional applications where error correction is critical.
1. ECC protection actively corrects single-bit errors in real time, safeguarding data integrity during long-running, mission-critical server workloads.
2. Dual-rank organization boosts memory interleaving efficiency, keeping the processor pipeline full and ensuring smooth performance for concurrent virtual machines.
3. The unbuffered signal path minimizes access latency, making it a cost-effective fit for entry-level server builds where every nanosecond counts.
4. Modest yet sufficient capacity allows dedicated hosting of light services like DNS or proxy gateways without over-provisioning system resources.
5. Elevated clock frequency supplies the necessary bandwidth headroom for simultaneous client requests in NAS or small-scale database operations.
The Micron MT18JSF1G72AZ-1G9E1ZF is an 8GB DDR3-1866 UDIMM with ECC, purpose-built for entry-level servers and mission-critical workstations. In a virtualized host running multiple VMs, data integrity is anything but optional. ECC actively corrects single-bit errors caused by background radiation, preventing silent data corruption that could crash a hypervisor or quietly damage a virtual disk image. For an in-memory database like Redis, a single flipped bit can return a faulty transaction value, leading to flawed analytics or direct financial loss; ECC erases that risk. The 1866MHz speed and PC3-14900 bandwidth deliver the low-latency access that keeps disk caches and concurrent VM requests fluid, while the Dual Rank x8 architecture interleaves memory banks to raise throughput precisely when a real-time cache engine demands rapid record retrieval. Standard 1.5V operation ensures broad compatibility across diverse server boards and minimizes thermal stress during 24/7 duty cycles, giving you a self-correcting foundation where uncompromised uptime and accurate data become your operational baseline.
This is an 8 GB DDR3-1866 ECC Unbuffered DIMM (UDIMM) tailored for entry-level servers and workstations. It fits single-socket platforms with up to four DIMM slots. Below is capacity planning guidance for typical server workloads.
General Virtualization
Deploy four of these 8 GB ECC UDIMMs (32 GB total) in a single-socket server to comfortably run 10–15 lightweight VMs. ECC protection safeguards against data corruption during memory ballooning and live migration.
In-Memory Database
Populate all four DIMM slots with the 8 GB ECC UDIMMs, providing 32 GB of cache memory. The dual-rank x8 architecture boosts parallel access, and ECC preserves data integrity for real-time or financial systems. For larger working sets, plan a transition to a registered DIMM platform.
High-Performance Computing
Equip each node with four identical 8 GB modules across all memory channels, enabling quad-channel interleaving for peak bandwidth. Unbuffered ECC delivers low latency and bit-flip protection during long-running simulations like molecular dynamics or CFD. This configuration offers both performance and reliability for scientific codes.
Strictly tested server memory, compatible with Dell PowerEdge T20, HP MicroServer Gen8, Lenovo ThinkServer TS140.
Q: Can I mix this MT18JSF1G72AZ-1G9E1ZF with other memory modules of different brands or speeds?
A: Mixing ECC UDIMMs of different brands or speeds is not advised. It risks system instability and ECC errors. For mission-critical reliability, always populate with identical modules.
Q: Is this memory compatible with my Intel or AMD server platform?
A: This DDR3-1866 ECC Unbuffered UDIMM is designed for server boards using Intel Xeon E3/E5 or AMD Opteron platforms. Verify your motherboard's memory QVL for precise compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board manual. Generally, fill the first slot of each channel with identical sticks to enable dual‑channel mode and maximize throughput for this dual‑rank module.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server‑grade ECC DIMM, it runs strictly at JEDEC standard 1866 MHz and CL13 to preserve data integrity. Overclocking and XMP are not supported.
Q: What warranty and typical failure rate can I expect?
A: It carries a 1‑year warranty. Built from high‑quality components, the typical annualized failure rate is below 0.5%, ensuring consistent reliability in 24/7 operation.
