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.
