Dell PowerEdge T140/T340/T40 compatible memory

This 16 GB DDR4 ECC unregistered DIMM is built for Dell PowerEdge T140, T340 and T40 servers. It installs in a 288-pin slot and runs at 2666 MHz with CL19 timing at 1.2 V. The module targets administrators who need reliable error-correcting memory for entry-level tower servers.

Upgrade from non-ECC or smaller capacity kits

The stick replaces standard non-ECC modules or lower-capacity DIMMs to add single-bit error correction and increase total system memory toward the 64 GB platform maximum across four slots. The jump is worth it when workloads demand data integrity and the server currently runs with unprotected memory or has free DIMM slots for expansion.

Sustained load behaviour without heat spreader

Under continuous operation the module operates at its rated 1.2 V and CL19 latency without a heat spreader, relying on chassis airflow for cooling. Faster memory will clock down to match the processor’s supported speed, so sustained throughput stays consistent at the platform’s native 2666 MHz rather than peaking higher in short bursts.

商品問答

Will this 288-pin DDR4 DIMM fit the four memory slots in my Dell PowerEdge T140, T340 or T40?

Yes. The module is a standard 288-pin DDR4 DIMM and the listed servers each provide four DIMM slots supporting up to 64 GB total.

What is the correct way to seat this unregistered ECC module, and what step do people often miss?

Align the notch with the slot key, press straight down until both side latches click, then verify in BIOS that the 2666 MHz speed and ECC function are recognised.

When will this 16 GB stick need replacement, and what should I watch for?

The limited lifetime warranty covers defects; replace the module if memory diagnostics report correctable ECC errors increasing over time or if the system fails to POST with this stick installed.
