8GB DDR4 2933MHz ECC UDIMM Module

This A-Tech server memory module delivers 8GB of DDR4 capacity at 2933MHz with PC4-23400 bandwidth. It operates at 1.20V standard voltage and features ECC error correction with an unbuffered design. The single-rank 1Rx8 configuration uses major brand chips for reliable operation in compatible systems.

Who This Suits and Who It Does Not

This module suits administrators upgrading or repairing servers and workstations that require DDR4 ECC UDIMM memory at 2933MHz. It is not for builders needing registered or load-reduced DIMMs, systems limited to lower DDR4 speeds, or platforms that only accept non-ECC consumer memory. Buyers who want higher capacities per slot should look at larger modules.

Build Integration Notes

The 288-pin DIMM fits standard DDR4 UDIMM slots in supported server and workstation motherboards. ECC functionality requires a platform that enables error correction in the BIOS or firmware. The 1.20V operation matches standard DDR4 voltage, so no special power configuration is needed. Verify your system's qualified vendor list before installation to ensure compatibility.

Questions about this item

My motherboard takes DDR4 288-pin DIMMs; will this 2933MHz CL21 1.20V ECC UDIMM work in it?

The module is a 288-pin DDR4 ECC UDIMM at 1.20V and CL21; it will function in any board that supports DDR4 ECC UDIMMs at 2933MHz or that can down-clock the module to a supported speed.

Can I mix this 8GB 1Rx8 stick with older DDR4 ECC UDIMMs of different capacities or ranks?

Mixing capacities and ranks is possible on platforms that support mixed populations; the memory controller will typically run all modules at the lowest common speed and tightest common timings.

How do I confirm the module is detected at 2933MHz with ECC active after installation?

Check the BIOS memory information or use an OS tool such as dmidecode, lshw or CPU-Z to verify speed shows 2933MHz, type shows ECC UDIMM and ECC status reports enabled.
