Server DDR3 ECC RDIMM

This A-Tech module is a 4 GB registered DDR3 DIMM rated at 1866 MHz with CL13 latency and 1.50 V operation. It uses a 1Rx8 organisation and major-brand chips to deliver error-correcting memory for server and workstation platforms.

240-pin installation and compatibility

The 240-pin DIMM fits standard DDR3 registered slots and requires no extra configuration beyond seating the module firmly until the latches click. The main risk is inserting a registered stick into a board that only accepts unbuffered memory, which will prevent the system from posting.

Suited for Micron replacement builds

Buyers replacing Micron MT9JSF51272PZ-1G9 or MT9JSF51272PZ-1G9E2 modules in compatible servers will find a direct match. Systems that need unbuffered non-ECC DDR3, higher capacities per slot, or a different memory generation should look elsewhere.

Questions about this item

How can I confirm the module is running at DDR3 1866 MHz with CL13 after installation?

Check the memory speed and latency in BIOS or use a tool like CPU-Z; it should show 1866 MHz and CAS latency 13 at 1.5 V.

What comes with the 4 GB DDR3 1866 ECC RDIMM and do I need anything else?

The box contains one 240-pin registered DIMM; no extra parts are required if your server has a free DDR3 ECC RDIMM slot.

Should I choose the 1Rx8 4 GB version or a different capacity for my Micron MT9JSF51272PZ-1G9 replacement?

This 1Rx8 4 GB module matches the Micron part exactly; select a different capacity only if your system supports larger registered ECC DIMMs.
