A-Tech 8GB DDR4 2933MHz ECC UDIMM

This A-Tech module is an 8GB DDR4 2933MHz ECC UDIMM built for server and workstation systems. It runs at PC4-23400 speed with CL21 latency and standard 1.20V voltage. The unbuffered, single-rank 1Rx8 design uses major-brand chips on a 288-pin DIMM. It serves as a compatible replacement for the IBM-Lenovo 4X71B32811 part number.

Suits ECC-capable servers needing UDIMM modules

This memory fits servers and workstations that accept DDR4 ECC UDIMMs at 2933MHz. Systems requiring registered or load-reduced DIMMs cannot use this unbuffered module. Buyers whose platforms demand higher capacities per slot or different speed grades should verify their motherboard specifications before ordering.

Module ships ready to install without extra items

The package contains only the single 8GB memory module itself. No additional cables, brackets, cooling hardware or software utilities are included. Installation simply requires an available 288-pin DDR4 DIMM slot and a system that supports ECC UDIMM operation at the rated speed and voltage.

Questions sur cet article

What motherboard slot and voltage does this 288-pin DDR4 2933MHz ECC UDIMM require?

It needs a standard DDR4 UDIMM slot that supplies 1.20V and accepts 288-pin unbuffered ECC modules.

Can I keep my existing CL21 1Rx8 DDR4 2933MHz ECC UDIMM modules and add this one alongside them?

Yes, if the motherboard supports mixed ranks and the same speed, voltage and ECC type; matching CL21 and 1Rx8 organisation helps stability.

How do I confirm the module is running at PC4-23400 with ECC active after installation?

Check BIOS or UEFI memory information for 2933MHz speed, 1Rx8 organisation and ECC enabled status.
