Dell Precision compatible 16 GB DDR4 module

This 16 GB DDR4 UDIMM is built for Dell Precision 3440, 3450, 3640 and 3650 workstations. It runs at 3200 MHz with CL22 latency at 1.2 V. The non-ECC unbuffered design suits standard desktop and workstation memory slots.

Tool-free DIMM installation with alignment keys

Insert the 288-pin module into an empty UDIMM slot until the retention clips click. The key notch prevents backward insertion, so the only common error is seating the module incompletely before locking the clips.

JEDEC DDR4 3200 speed ceiling with backward steps

The module follows JEDEC DDR4 3200 (PC4-25600) specifications and will down-clock to 2133, 2400, 2666 or 2933 MHz if the platform requires it. Systems that only support lower DDR4 speeds or registered ECC memory cannot use this UDIMM.

Spurningar um þessa vöru

How do I confirm the OWC 3U2D42R816GB module is running at 3200 MHz CL22 after installation?

Open Task Manager or CPU-Z in Windows and check the memory tab; it should show 3200 MT/s and CAS latency 22 for the new 16 GB stick.

What comes in the box with the OWC 3U2D42R816GB and do I need anything else to install it in a Dell Precision 3640?

The box contains the single 16 GB 288-pin DDR4 UDIMM; no extra tools or cables are required for the Precision 3640 DIMM slots.

Should I choose the 16 GB 3200 MHz CL22 version or a different capacity for my Precision 3450?

This 16 GB DDR4 3200 CL22 module is the specific part validated for Precision 3440, 3450, 3640 and 3650; other capacities carry different part numbers.
