8GB ECC SODIMM for HP workstations

This A-Tech module delivers 8GB of DDR4 2400MHz memory with ECC error correction for compatible HP server and workstation laptops. It operates at the standard 1.2V voltage and uses a 260-pin SO-DIMM form factor with CL17 latency. The unbuffered design suits systems that require registered ECC memory in a laptop footprint.

Major-brand chips validated for HP part numbers

The module uses major-brand memory chips tested to match HP part numbers 862398-852, Y7B56AT, Y7B56AA, 863951-B21 and 1CA79AT. This validation aims to ensure the ECC functionality and timing parameters work correctly in the listed server and workstation platforms. No additional software or accessories are included with the memory stick itself.

Simple slot insertion with BIOS verification

Installation follows the standard SO-DIMM procedure: power off, open the memory compartment, align the 260-pin notch, and press until the clips engage. The most common issue is a system that does not support unbuffered ECC SODIMMs, which will fail to post or disable the ECC feature. Always confirm the laptop's service manual lists ECC unbuffered support before fitting.

Questions about this item

Will the ECC unbuffered SODIMM need any firmware updates or chip replacements over its service life?

No firmware updates or chip replacements are required; the module uses major-brand DDR4 chips tested for dependable long-term operation.

What thermal or voltage limit appears first when the 1.20V CL17 module runs at 2400 MHz continuously?

The JEDEC-standard 1.20 V ceiling is reached before any thermal throttle point under sustained DDR4-2400 loads.

How much fan noise or case heat does the 260-pin ECC SODIMM add during all-day server workloads?

The unbuffered DDR4 design draws only standard 1.2 V power, adding negligible heat and requiring no extra cooling airflow.
