Server ECC UDIMM Upgrade

This A-Tech module adds 8 GB of DDR4 error-correcting memory to compatible servers and workstations. It is an unbuffered DIMM built for systems that require ECC data integrity. The single stick suits upgrades where only one slot is free or where matched pairs are not mandatory. Desktop and laptop platforms cannot use this module.

DDR4 2933 CL21 1Rx8 Spec

The stick runs at 2933 MHz with a CAS latency of 21 at the standard 1.20 V. It is organised as a single-rank 1Rx8 device on a 288-pin PCB. Only platforms qualified for DDR4 2933 ECC UDIMM memory will recognise and operate the module correctly.

Simple Slot Installation

Installation follows the usual DIMM procedure: align the notch, press until the latches click, and verify seating in the firmware memory map. The most common issue is inserting the module into a desktop or laptop board that does not support ECC unbuffered memory, which results in a no-post condition.

Questions about this item

What does the 2933 MHz rating mean once the module is installed in a server?

The module will run at 2933 MHz if the platform supports that speed; otherwise it will downclock to the highest speed the memory controller allows.

How does the ECC UDIMM interface affect usable bandwidth?

ECC adds error correction without buffering, so the full 23400 MB/s theoretical bandwidth is available to the CPU with single-bit error detection and correction.

What physical slot and clearance does this 288-pin DIMM require?

It fits a standard DDR4 288-pin UDIMM slot and has no heat spreader, so it clears most CPU coolers and dense server chassis.
