32 GB DDR4 3200 MHz for Dell Precision workstations

This OWC UDIMM adds 32 GB of DDR4 3200 MHz memory to compatible Dell Precision 3440, 3450, 3640 and 3650 systems. It is built for professionals who need more capacity for multitasking, large datasets or virtual machines. The module is new, non-ECC and unbuffered, matching the factory specifications for these workstations. Buyers who need ECC error correction or registered memory for server platforms should look elsewhere.

Fits standard 288-pin DDR4 slots in the listed

The 288-pin UDIMM installs directly into the desktop memory slots of the supported Precision towers and small-form-factor units. It operates at 1.2 V and runs at CL22 latency, with backward compatibility at 2133, 2400, 2666 and 2933 MHz if the system requires a lower speed. No heat spreader is included, so airflow in the chassis handles cooling. The module frees the builder from sourcing matched pairs when only a single 32 GB upgrade is needed.

JEDEC and RoHS compliant with lifetime warranty

OWC validates every module to meet or exceed JEDEC standards and RoHS requirements, ensuring a warranty-safe upgrade for the supported Dell systems. The package includes the memory module only; no cables, brackets or software discs are supplied. Free technical support is available from OWC for installation questions. The advanced replacement programme covers the limited lifetime warranty period.

Questions about this item

What is the CAS latency of the OWC 32GB DDR4 3200MHz module?

The module runs at CL22 latency, which is the standard timing for JEDEC DDR4-3200 operation.

Does the module include a heat spreader for all-day thermal management?

No, this UDIMM does not have a heat spreader; it relies on the workstation's internal airflow for cooling during sustained workloads.

Which Dell Precision workstations must I already own for this memory to be compatible?

This kit is validated for the Dell Precision 3440, 3450, 3640 and 3650 models.
