Lenovo ThinkSystem DDR5 ECC RDIMM

This 16GB DDR5 4800 registered DIMM adds ECC-protected memory to Lenovo ThinkSystem servers built for AMD processors. The single-rank 1Rx8 module targets administrators who need to expand capacity without replacing existing sticks.

Single module with validated compatibility

The package contains one 288-pin RDIMM tested for the 4X77A81437 part number. No cables, brackets or software utilities are included, so the only change after installation is the additional 16GB of error-correcting capacity.

Standard DIMM slot installation

The module seats in any compatible DDR5 RDIMM slot using normal insertion force. Common issues arise when mixing registered and unbuffered memory or when the server BIOS has not been updated to recognise the new capacity.

Domande su questo articolo

Will the 1Rx8 DDR5 4800 module need any firmware updates or chip replacements during its service life?

No firmware or chip replacements are required; the module is a fixed hardware component validated for the Lenovo ThinkSystem platform.

What limit appears first when the RDIMM runs at 4800 MT/s continuously in a server chassis?

The registered buffer and ECC logic operate within the 1.10 V specification, so thermal limits of the chassis airflow typically appear before any electrical limit of the module.

How much heat and noise does the 16 GB CL40 stick add when the system runs all day?

The module has no heat spreader and draws 1.10 V, so it adds minimal heat and zero acoustic noise; system fan speed determines overall thermal and acoustic profile.
