Lenovo-compatible 64GB DDR5-4800 RDIMM

This registered ECC module delivers 64GB of DDR5-4800 memory in a 2Rx4 configuration for Lenovo servers. It is built with a major-brand chipset and matches Lenovo part number 4X77A81441 for drop-in compatibility.

100% Lenovo compatibility and lifetime warranty

The module is validated as a direct equivalent to the original Lenovo part, so firmware recognition and ECC functionality work without extra configuration. A lifetime warranty from the supplier covers the memory for as long as it remains in service.

Verify DDR5 RDIMM slots and 2Rx4 support

Confirm that your server platform accepts DDR5 registered DIMMs and can populate a 2Rx4 rank layout in the intended channel. Check the system’s qualified-vendor list or service manual to ensure the 64GB density is supported per socket.

Questions about this item

Will the 2Rx4 ECC registered RDIMM organisation need any firmware updates or rank-specific maintenance later?

The module uses a fixed 2Rx4 organisation with on-die ECC; no firmware updates or rank-specific maintenance are required during its service life.

What thermal or bandwidth limit appears first when the DDR5-4800 sticks run at full load continuously?

Sustained full-load operation is limited by the DDR5-4800 data rate and the PC5-38400 peak bandwidth ceiling before thermal throttling engages.

How much heat and power does a 64GB PC5-38400 module produce when it runs all day in a server chassis?

Typical DDR5 RDIMM power draw stays in the low single-digit watt range per module, producing modest heat that standard server airflow handles without extra cooling.
