NEMIX RAM 32GB DDR5 4800 ECC UDIMM

This 32GB DDR5 ECC unbuffered UDIMM is built for Intel-based Lenovo ThinkSystem servers and workstations. It targets IT professionals upgrading compatible platforms with validated, error-correcting memory. The module operates at 4800MHz with a CL40 latency and 1.10V voltage. It requires a system that supports DDR5 ECC UDIMM architecture.

CL40 latency at DDR5 4800 speed

The CAS latency of CL40 at the DDR5 4800 (PC5-38400) data rate is the primary timing specification that determines compatibility with the memory controller. This timing must match the platform's qualified vendor list for stable operation. The 2Rx8 rank organisation and 288-pin interface are fixed physical and logical traits. Systems requiring different latencies, speeds, or registered DIMMs cannot use this module.

Fits Lenovo ThinkSystem 4X77A88512 slot

Installation uses a standard 288-pin DDR5 UDIMM slot in compatible Lenovo ThinkSystem servers. The unbuffered design connects directly to the memory controller without a register, freeing a registered-DIMM slot for other configurations. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis. Buyers needing registered DIMMs, higher capacities per slot, or non-ECC memory for consumer platforms should look elsewhere.

Questions about this item

What does the 4800 MT/s speed mean for real-world throughput in my Lenovo ThinkSystem?

The module transfers data at 4800 MT/s; sustained throughput is determined by the platform memory controller and the workload you run.

How does the DDR5 288-pin interface limit the maximum speed this DIMM can reach?

The 288-pin DDR5 slot caps the module at its rated 4800 MT/s; faster DDR5 speeds require a platform that supports them.

Will the 32 GB 2Rx8 stick fit in a standard Lenovo ThinkSystem UDIMM slot without a heat spreader?

Yes, the bare 288-pin UDIMM is 32 GB in a 2Rx8 layout and installs directly into a compatible ThinkSystem DIMM slot.
