128GB DDR5 ECC RDIMM for Lenovo servers
This 128GB DDR5 4800 CL40 registered DIMM targets administrators expanding memory in Lenovo ThinkSystem servers that require ECC RDIMM modules. The 4Rx4 organisation and 1.1V operation match the platform specifications for Intel processor based systems. It is not suited for desktop boards or laptops that accept only unbuffered memory.
Sustained load behaviour
Registered buffering and on-die ECC keep data integrity intact during continuous enterprise workloads such as virtualisation, database serving and large-scale analytics. The CL40 latency at 4800 MT/s provides steady throughput without the timing variability seen in consumer modules under prolonged stress. No heat spreader is fitted, so adequate chassis airflow is required to maintain rated performance.
Installation notes
The single 288-pin module seats in any compatible DDR5 RDIMM slot; consult the server service manual for population rules and maximum supported capacity per channel. Common issues arise when mixing ranks or voltages across channels, so populate identical modules together. The system BIOS must recognise the 4Rx4 configuration at 1.1V for correct initialisation.

商品問答
How much power does the 128GB DDR5 4800 CL40 module draw at its rated 1.1V?
The module operates at 1.1V, which is the standard DDR5 voltage, keeping power draw low for a 128GB registered DIMM.
What motherboard slot and CPU memory controller are required for this 288-pin DDR5 RDIMM?
You need a server motherboard with DDR5 RDIMM slots and a CPU that supports registered ECC memory at 4800MT/s.
Will this 4Rx4 DDR5 4800 RDIMM work in a Lenovo ThinkSystem that currently uses 2Rx8 DDR5 modules?
Yes, the 4Rx4 organisation is compatible with Lenovo ThinkSystem platforms qualified for the 4X77A77034 part number.
