8GB DDR4 ECC UDIMM for Servers

This 8GB DDR4 2400 ECC UDIMM module targets administrators who need to add reliable memory to compatible servers or workstations. It delivers error-correcting code protection without registered buffering. The unbuffered design suits platforms that accept UDIMM population rules.

Replaces Hynix HMA41GU7AFR8N-UH

The module is a direct equivalent for the Hynix HMA41GU7AFR8N-UH part number. Upgrading makes sense when a system currently runs lower-capacity DDR4 ECC UDIMMs at 2400 MT/s and the board supports 2Rx8 organisation. Verify the platform's qualified-vendor list before ordering.

Fits 288-pin DDR4 slots at 1.2V

Installation requires an available 288-pin DDR4 DIMM slot that accepts unbuffered ECC memory at 1.20V. The single 8GB stick leaves remaining slots free for further expansion within the motherboard's maximum capacity. Confirm the system's supported rank and speed configuration before installation.

Questions about this item

What DDR4 slot and pin count does this 288-pin UDIMM require?

It fits a standard DDR4 DIMM slot with 288 pins and operates at 1.20 V.

Which notch orientation and seating pressure avoid a partial install?

Align the single off-centre notch with the slot key, press straight down until both side clips click, and verify the module sits flush.

When should this ECC module be replaced if correctable errors appear?

Replace the module if the system logs show a rising correctable-error count or if memory diagnostics report persistent failures.
