Compatible Dell PowerEdge Memory Kit

This 16 GB kit contains two 8 GB DDR4 2666 ECC unregistered DIMMs built for Dell PowerEdge T140, T340 and T40 servers. It targets administrators who need to expand memory on those specific platforms without mixing speeds or capacities.

Steady Workload Behaviour

ECC protection corrects single-bit errors during continuous operation, helping prevent data corruption on long-running tasks. Modules run at 1.2 V with CL19 timing, so power draw and latency stay consistent under sustained load rather than spiking during short bursts.

Plain DIMM Build

The sticks use a standard 288-pin layout without heat spreaders, fitting directly into the four available slots on each supported server. Buyers who need more than 64 GB total capacity or registered memory for other platforms will not be served by this kit.

Questions about this item

Does the 1.2 V DDR4 2666 kit generate noticeable heat or fan noise when the T140 runs all day?

The modules run at standard 1.2 V without heat spreaders, so they add minimal thermal load to the server's existing airflow.

What must already be present in the chassis for this D104 kit to work?

A Dell PowerEdge T140, T340 or T40 with free 288-pin DDR4 DIMM slots and a processor that supports ECC unregistered memory.

Will these CL19 2666 MHz modules run correctly beside any existing factory memory in a T340?

Faster memory will clock down to run at optimal speed depending on the processor model installed.
