128GB DDR5 4800 ECC Registered RDIMM

This Brute Networks module delivers 128GB of DDR5 4800 server memory with ECC and registered buffering. It matches Lenovo part number 03GX339 and uses major brand chipsets for full compatibility. The PC5-38400 rating ensures standard DDR5 server performance.

Suited for Lenovo servers needing maximum

This module suits administrators upgrading Lenovo systems that require 4Rx4 registered ECC DDR5. It is not for workstations or desktops that accept only unbuffered memory. Buyers needing lower densities or non-ECC modules should look elsewhere.

4Rx4 registered ECC organisation

The 4Rx4 rank architecture defines how the memory controller addresses this 128GB stick. Verify your server's memory population rules support 4Rx4 registered DIMMs before purchase. This single specification determines fit.

Questions about this item

What does the 4800 MT/s speed mean for actual throughput in a server?

The module runs at DDR5-4800, giving a peak data rate of PC5-38400, so sustained bandwidth in a compatible server will reach that ceiling.

How does the registered ECC design affect the memory controller?

Registered buffering adds one clock cycle of latency but reduces electrical load, letting the controller drive large capacities like this 128 GB stick reliably.

Will this 288-pin RDIMM fit my Lenovo server's memory slots?

Yes, it is a standard DDR5 288-pin RDIMM built to Lenovo part 03GX339, so it seats directly in supported Lenovo server DIMM sockets.
