8GB DDR4 2133 ECC UDIMM Server Module

This 8GB DDR4 2133MHz ECC UDIMM module is built for servers and workstations that require error-correcting memory. It operates at 1.20V with CL15 latency and uses a 2Rx8 rank configuration on a 288-pin DIMM form factor.

Direct Hynix HMA41GU7AFR8N-TF Replacement

The module is specified as a compatible equivalent for the Hynix HMA41GU7AFR8N-TF part number. It uses major brand chips and undergoes quality assurance testing to ensure dependable performance in supported systems.

Unbuffered ECC DDR4 2133MHz Specification

This is an unbuffered ECC DDR4 module running at 2133MHz (PC4-17000). Verify that your system specifically supports unbuffered ECC DDR4 at this speed before purchase, as registered or non-ECC memory will not function correctly.

Questions about this item

Will the ECC UDIMM chips or the 288-pin contacts need periodic replacement in a server?

The module uses major-brand chips on a standard 288-pin DDR4 UDIMM with no moving parts or serviceable components, so no scheduled chip or contact replacement is required.

What limits sustained throughput on the 2133 MHz CL15 2Rx8 module?

Sustained throughput is capped by the DDR4 2133 MT/s data rate and CL15 latency of the 2Rx8 organisation.

How much heat does the 1.20 V DDR4 UDIMM generate during continuous operation?

At the standard 1.20 V DDR4 voltage the module produces only modest heat and runs silently with no active cooling needed.
