Server Memory for ECC Workstations

This A-Tech module delivers 4GB of DDR4 2400 ECC UDIMM memory designed for server and workstation systems. It operates at CL17 latency with a standard 1.20V voltage. The unbuffered design suits platforms that require error-correcting code without registered signalling. It serves as a direct replacement for the Hynix HMA451U7AFR8N-UH part.

288-Pin UDIMM Integration

The stick fits a standard 288-pin DDR4 DIMM slot and requires a motherboard that supports ECC UDIMM operation at 2400 MT/s. Because it is unbuffered, it does not add the electrical load of registered modules, leaving the memory controller free for other ranks. Builders must confirm their platform accepts ECC unbuffered memory before installation.

Sustained Load Stability

Major-brand chips and factory testing target reliable operation during continuous workloads such as virtualization or file serving. ECC circuitry corrects single-bit errors on the fly, preventing data corruption over long uptimes. The 1.20V standard voltage keeps power draw consistent under load. Systems without ECC support cannot use the error-correction capability.

Questions about this item

Does the CL17 latency limit throughput when the module runs at 2400 MHz for long periods?

CL17 is the rated timing at DDR4 2400; sustained workloads stay within that specification.

How much heat or power does the 1.20 V unbuffered ECC DIMM produce during all-day operation?

At the standard 1.20 V DDR4 voltage the module runs cool and draws minimal power for continuous server use.

Which motherboard slot and chipset support are required for this 288-pin DDR4 ECC UDIMM?

A DDR4 288-pin UDIMM slot with ECC support in the platform chipset is needed for the module to function.
