4GB DDR3 1866 ECC UDIMM for servers
This 4GB DDR3 1866 ECC UDIMM module targets servers and workstations that require error-correcting unbuffered memory. It replaces Micron MT9JSF51272AZ-1G9E2 and MT9JSF51272AZ-1G9P1 parts in compatible platforms. The single-rank 1Rx8 organisation suits systems that populate multiple slots per channel.
Installation notes for 240-pin DDR3
The module uses the standard 240-pin DDR3 DIMM keying and installs like any unbuffered DDR3 stick. Align the notch, press evenly until the latches click, and verify the BIOS reports 1866 MT/s at CL13. Mismatched ranks or mixing registered and unbuffered DIMMS are the usual reasons a system will not post.
4GB capacity and DDR3 1866 headroom
Four gigabytes handles light virtualisation, file-serving and legacy application workloads without paging. Heavy databases, large VM counts or memory-intensive analytics will exhaust the module quickly. The 1.50V DDR3 standard voltage limits overclocking headroom, so the rated 1866 speed is the practical ceiling.

이 상품에 대한 질문
How can I confirm the module is running at 1866 MHz with ECC active after installation?
Check the BIOS memory information screen; it should show DDR3 1866 speed, 1.50 V voltage, ECC enabled and the correct 4 GB capacity.
What comes in the package and do I need any extra parts to install it?
The box contains one 4 GB 240-pin DDR3 UDIMM; no cables, brackets or additional components are required for installation.
Which version should I choose if my server lists Micron MT9JSF51272AZ-1G9E2 or MT9JSF51272AZ-1G9P1?
This module is a compatible replacement for both Micron part numbers, so either listing points to the same 4 GB DDR3 1866 ECC UDIMM.
