Micron 32GB DDR4 4800 RDIMM Server Memory

This Micron registered DIMM delivers 32GB of DDR4 4800 memory for server and workstation platforms. It operates at CL40 with 40-39-39 timings and a 1.1V voltage. The module includes a register chip to manage data flow and integrated ECC parity for error detection. It is a dual-rank 2Rx8 design without a heat spreader.

Suited for registered DDR4 slots needing ECC parity

This module fits systems that require registered DDR4 memory with ECC parity at 4800 MT/s. It is not for platforms limited to unbuffered UDIMMs or those requiring a different DDR generation. Builders needing lower latency timings or higher capacities per slot should evaluate other options. Systems without registered memory support cannot use this RDIMM.

Registered DDR4 4800 with CL40 and ECC parity

The registered architecture combined with DDR4 4800 speed and CL40 latency determines compatibility with qualified server boards. The 2Rx8 organization and parity ECC provide specific reliability characteristics for supported platforms. Verify that the target system accepts registered DDR4 modules at this speed and rank configuration before purchase.

Questions about this item

At what speed does the module operate when the server runs continuously?

The module runs at DDR4 4800 (PC4-38400) under sustained load.

How much heat or noise does the 1.1V RDIMM add during all-day operation?

It draws 1.1 V with no heat spreader, so thermal output stays low and the module adds no audible noise.

Which server platform must already support registered ECC memory for this 32 GB stick to work?

The motherboard must accept DDR4 RDIMMs with registered parity ECC and 2Rx8 organisation.
