8GB DDR4 2933 ECC RDIMM

This A-Tech module is an 8GB DDR4 2933 ECC Registered DIMM built for server and workstation platforms. It delivers 2933 MHz speed with CL21 latency at the standard 1.2V operating voltage. The single-rank 1Rx8 organisation uses major-brand chips and targets HP part numbers L15415-501 and L58119-001. Buyers who need non-ECC memory or consumer UDIMM form factors cannot use this product.

Registered DIMM for 288-pin DDR4 slots

The module plugs into a standard 288-pin DDR4 DIMM socket and requires a platform that supports Registered ECC memory. Error-correction and register buffering reduce electrical load on the memory controller, freeing capacity headroom for large multi-module configurations. Systems limited to unbuffered UDIMMs or those without ECC support in the BIOS will not accept this module.

Replaces HP L15415-501 and L58119-001

This kit serves as a direct replacement for the listed HP part numbers, restoring or expanding memory capacity in compatible servers. The upgrade is worthwhile when the system reports correctable ECC errors, shows memory bottlenecks under virtualised workloads, or simply needs more installed RAM to run additional virtual machines.

Questions about this item

What is the first limit under sustained use with the 2933 MHz DDR4 RDIMM?

The registered buffer and ECC logic maintain signal integrity at full 2933 MHz speed, so the primary limit is the 8 GB capacity per module rather than a thermal or timing ceiling.

How much heat or noise does the 1.2 V registered ECC module produce during all-day operation?

At 1.2 V the module runs cool with no moving parts, so it adds negligible heat and zero audible noise to a server chassis running continuously.

What must the system already have for this 288-pin DDR4 RDIMM to work?

The motherboard must provide DDR4 RDIMM slots that support ECC registered memory and a memory controller able to address 1Rx8 modules at 2933 MHz.
