Dell Precision 3430 3431 3630 memory upgrade

This 16 GB DDR4 module is built for Dell Precision 3430 Small Form Factor, 3431 Desktop and 3630 Tower workstations. It runs at 2666 MHz with CL19 timing at 1.2 V and uses a non-ECC, unbuffered 288-pin design. The single stick adds 16 GB to the four-slot platform.

Fits four DIMM slots without ECC

The workstation motherboard provides four DDR4 slots supporting up to 64 GB total. This module occupies one slot and leaves three free for further expansion. Because it is non-ECC, it matches the requirement for Core i5 and i7 processors, while Xeon E-2xxx, Core i3 and Pentium CPUs also accept it. Mixing with ECC modules is not recommended.

Single stick with lifetime warranty

The package contains one 16 GB DIMM backed by a limited lifetime warranty from Computer Memory Solutions. No heat spreader is included, keeping the profile low for small-form-factor chassis. Product appearance may vary from the reference image.

Questions about this item

What speed does this DDR4 2666 module drop to if the installed processor only supports a lower memory frequency?

Faster memory will clock down to run at the optimal speed supported by the specific processor model installed in the Dell Precision 3430, 3431 or 3630.

Does this unbuffered non-ECC DIMM generate extra heat or noise during continuous operation in a Dell Precision tower?

The module runs at 1.2V without a heat spreader, adding no moving parts or active cooling; thermal output matches standard DDR4 DIMM behaviour inside the chassis.

Which Dell Precision models must the workstation already be for this 288-pin 16 GB stick to be compatible?

The memory is validated for Precision 3430 Small Form Factor, Precision 3431 Desktop and Precision 3630 Tower systems with Intel Core or Xeon processors.
