Questions about this item

Does my Lenovo server need an ECC RDIMM slot to accept this 32GB DDR5-4800 module?

Yes, this module is a registered ECC RDIMM and requires a DDR5 RDIMM slot on a compatible Lenovo server motherboard.

Can I mix this 2Rx8 DDR5-4800 stick with other DDR5-4800 RDIMMs in the same server?

Mixing ranks is possible on many Lenovo platforms, but matching the 2Rx8 organisation and 4800 speed ensures the memory controller runs all channels at the rated frequency.

How can I verify the module is running at the correct 4800 MT/s after installation?

Enter the server BIOS or use a tool like ipmitool to confirm the memory speed reads 4800 MT/s and the capacity shows 32 GB per DIMM.
