HP Z238 Z240 memory kit

This 8 GB kit contains two 4 GB DDR4 DIMMs built for HP Z238 and Z240 Tower or SFF workstations. It targets IT teams and power users who need a matched pair to fill two of the four available slots without mixing modules. The unbuffered non-ECC design matches the platform's standard memory configuration.

Thermals noise power

Operating at 1.2 V, the modules run cool enough for the compact SFF chassis and do not add audible fan load under normal office workloads. No heat spreaders are fitted, keeping the profile low for tight clearance between the CPU cooler and the side panel. Power draw stays within the workstation's standard memory budget.

CL17 2400 MHz timing

The kit runs at DDR4 2400 (PC4 19200) with CL17 17-17-17 timings and a 2Rx8 rank structure. This specification decides whether the memory will POST at rated speed on the Z238 or Z240 platform; systems that require different latency or voltage will not benefit from this kit.

Preguntas sobre este artículo

How do I install the 288-pin DDR4 DIMMs in my HP Z240 and which slot order matters?

Power off the workstation, open the case, and insert each 4 GB module into the same-coloured DIMM slots — typically slots 1 and 3 — until the retention clips click.

What maintenance or replacement will the CM512642400DIMM kit need over its lifetime?

No scheduled maintenance is required; the modules carry a limited lifetime warranty from Computer Memory Solutions against manufacturing defects.

What limit appears first when the 2400 MHz CL17 memory runs sustained workloads?

The JEDEC-standard 1.2 V operating voltage and CL17 latency define the thermal and timing ceiling under continuous load.
