Server memory module

This Dell A9654881 module provides 8 GB of DDR4 ECC unbuffered memory for compatible PowerEdge servers. It operates at 2400 MHz with CL15 latency and a 1.20 V supply. The single 288-pin DIMM is designed for server workloads that require error correction.

Suited for ECC unbuffered slots only

This module fits servers that accept unbuffered ECC DDR4 DIMMs such as the listed PowerEdge models. It will not work in systems that require registered or load-reduced memory. Buyers who need higher capacities or registered modules should look at other parts.

2400 MHz CL15 unbuffered ECC

The memory runs at 2400 MHz with CL15 timing and unbuffered ECC signal processing. This specification determines compatibility with the supported PowerEdge R230, R330, T130, T30 and T330 servers. Verify that your platform requires unbuffered ECC before purchase.

Questions about this item

Will the ECC unbuffered DDR4 DIMM need any firmware updates or battery-backed maintenance over time?

No firmware or battery maintenance is required; the module is a standard 288-pin DDR4 DIMM that operates at 1.20 V with CL15 timing and ECC error correction built into the silicon.

What limit appears first when the module runs continuously at 2400 MHz in a server chassis?

The 1.20 V operating voltage and CL15 latency define the thermal envelope; sustained loads will hit the platform's memory-controller thermal limit before the DIMM itself reaches a hard error threshold.

How much heat and fan noise does a single 8 GB stick add when the server runs all day?

At 1.20 V the stick draws minimal power, adding only a few watts of heat that the existing server airflow handles without increasing fan speed or audible noise.
