8GB DDR4 ECC UDIMM for servers

This 8GB DDR4 2133 module adds ECC unbuffered memory to compatible server and workstation platforms. It runs at PC4-17000 speed with CL15 latency and 1.20V standard voltage. The single-rank 1Rx8 organisation uses major-brand chips on a 288-pin DIMM. It is sold new as a direct replacement for HP part numbers 803660-091, 819880-B21 and 823170-001.

Replaces non-ECC or lower-capacity UDIMMs

Swapping standard unbuffered DIMMs for this ECC version adds single-bit error correction without requiring registered memory support. The upgrade is worthwhile when the platform accepts unbuffered ECC and the workload demands data integrity over maximum density. Systems already populated with registered DIMMs cannot use this module.

Fits 288-pin DDR4 slots with ECC support

The module installs in any DDR4 UDIMM slot that enables ECC in the firmware. It draws standard 1.2V power and does not need additional cooling or a registered-memory controller. Builders must confirm the motherboard or server manual lists unbuffered ECC at 2133 MT/s before purchase. It frees no extra slots beyond the single DIMM occupied.

Questions about this item

Does the 288-pin DDR4 UDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 UDIMM form factor matches standard unbuffered server memory slots that accept DDR4 modules.

What is the correct orientation when seating the 1Rx8 module?

Align the notch on the module edge connector with the key in the slot, press down firmly until the retention clips click into place on both sides.

Will the ECC function remain active for the module's lifetime?

ECC capability is a hardware feature of the DRAM chips and does not degrade; the module retains error-correction function as long as it operates within the 1.2V specification.
