32GB DDR5 ECC UDIMM for server workloads

This 32GB DDR5 4800MHz ECC UDIMM uses a 2Rx8 layout and runs at 1.10V. It is built for servers and workstations that require error-correcting memory in an unbuffered form factor. The module fits standard 288-pin DDR5 slots and replaces the Hynix HMCG88AEBEA part.

Sustained operation with ECC integrity

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing data corruption under heavy memory loads. The 2Rx8 organisation allows the memory controller to interleave accesses across ranks, helping maintain throughput during long-running tasks. CAS latency of 40 cycles is consistent with DDR5-4800 JEDEC timing.

Unbuffered ECC limits platform choice

This module is unbuffered ECC UDIMM, so it only works in platforms that explicitly support unbuffered ECC memory. Registered or fully buffered systems cannot use it, and consumer boards without ECC support will not enable the error-correction function. Verify your motherboard or server manual lists unbuffered ECC UDIMM compatibility before purchase.

Questions about this item

How much power does the 1.10V DDR5 module draw when the server runs continuously?

The module operates at the standard DDR5 voltage of 1.10V. Actual power draw depends on the platform's memory controller and workload; the module itself has no separate power rating.

What motherboard slot and chipset support are required for this 288-pin DDR5 ECC UDIMM?

You need a motherboard with a 288-pin DDR5 UDIMM slot that supports ECC unbuffered memory. Check your system manual for qualified memory lists and channel population rules.

Will this 4800MHz 2Rx8 module run stably alongside slower DDR5 sticks I already have?

The module is rated for DDR5 4800 (PC5-38400) at CL40. If mixed with slower DDR5, the system will clock all modules to the lowest common speed and loosest timings.
