A-Tech 128GB DDR5 4800 ECC RDIMM

This A-Tech server memory module provides 128GB of DDR5 4800 capacity in a single registered DIMM. It operates at 1.1V with a CAS latency of CL40 and features ECC error correction for data integrity. The 288-pin module uses a 2S2Rx4 (4Rx4 EC8) rank configuration with 3DS/TSV stacking technology.

Suited for HP systems requiring the N20163-001

This module serves as a compatible replacement for the HP N20163-001 specification in server and workstation environments. Builders needing unbuffered UDIMM memory or platforms that do not support registered ECC RDIMMs should select a different module type. Systems limited to lower maximum module densities cannot accommodate this 128GB capacity.

Registered ECC RDIMM with 2S2Rx4 rank configuration

The registered buffer and ECC functionality require a motherboard chipset and CPU that explicitly support registered DDR5 RDIMMs. The 2S2Rx4 (4Rx4 EC8) organisation uses 3DS/TSV stacking to achieve the 128GB density within a single 288-pin DIMM slot. Verify your platform's qualified vendor list for this exact rank structure before purchase.

商品問答

Will the registered ECC RDIMM design or the major-brand chipset need any scheduled replacement?

The module is a registered ECC RDIMM built with a major-brand chipset and has no moving parts, so no scheduled replacement is required.

What limit appears first when the CL40 4800 MHz module runs at full load continuously?

Sustained full-load operation will hit the DDR5 4800 MHz data-rate ceiling before any other bottleneck.

How much heat and power does the 1.1 V registered DIMM produce when running all day?

At the standard 1.1 V DDR5 voltage the 128 GB module draws minimal power and generates low heat, keeping noise negligible in a server chassis.
