128GB DDR5 4800 Registered DIMM

This 128GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10 V operation. The registered design buffers address and command signals to reduce electrical load on the memory controller. It targets servers and workstations that require maximum capacity per slot and error-correcting stability.

288-pin DIMM installation notes

Align the notch on the module with the key in the slot and press firmly until both retention clips click into place. Registered DIMMs will not function in consumer desktop boards that lack registered-memory support; the system will fail to post or recognise the module. Handle only the edges to avoid contaminating the gold contacts.

Platform requirements before ordering

Verify that your motherboard and processor officially support DDR5 registered DIMMs at 4800 MHz and 1.10 V. Confirm the board provides enough DIMM slots for your planned capacity and that the BIOS is updated to the version that enables registered memory. Without registered-memory support the module will not work.
