16GB DDR4 module for HP Z240

This 16GB DDR4-2133 CL15 DIMM is built for HP Workstation Z240 Tower and SFF systems. It targets professionals who need to expand memory on these specific platforms without using ECC modules. The unbuffered 2Rx8 design runs at 1.2V and fits the 288-pin DDR4 slots found in the listed workstations.

Before ordering verify your CPU

Check which processor is installed because memory requirements differ. Intel Xeon E3 and Core i3 CPUs accept either ECC or non-ECC UDIMMs, while Core i5 and i7 CPUs require non-ECC UDIMMs only. The system has four slots with a 64GB maximum, and modules must be installed in matched pairs to enable dual-channel operation. Mixing ECC and non-ECC sticks is not recommended.

Pair install frees remaining slots

Adding this stick as part of a matched pair activates dual-channel bandwidth and leaves two slots open for future expansion up to the 64GB limit. The non-ECC unbuffered design keeps the memory subsystem simple for Core i5 and i7 configurations. No heat spreader is included, so airflow around the DIMM area should be adequate for the 1.2V operating voltage.

Questions about this item

Does the package contain a single 16 GB stick or a matched pair, and is anything else required for installation?

The box includes one 16 GB 288-pin DDR4 DIMM rated at 2133 MHz CL15 1.2 V; the system has four slots and supports up to 64 GB, so a second identical module must be purchased separately to run in dual-channel mode.

Should I choose this non-ECC 2Rx8 module or an ECC alternative for the Z240?

The Z240 accepts both ECC and non-ECC UDIMMs, but mixing them is not recommended; with a Core i5 or i7 processor you must use non-ECC modules such as this one, while a Xeon E3 or Core i3 can use either type.

What does the 2133 MHz rating mean once the module is installed in the workstation?

The stick will operate at DDR4-2133 (PC4-17000) with 15-15-15 timings at 1.2 V; the Z240 memory controller runs non-ECC UDIMMs at this speed by default, delivering the rated bandwidth without manual configuration.
