OWC 8GB DDR4 module for HP Z240

This OWC 8GB DDR4 2133MHz CL15 1.2V 288-pin UDIMM is a system-specific memory upgrade designed for HP Z240 Workstation SFF and Tower models. It targets professionals and IT managers who need a compliant, JEDEC-standard module to increase capacity in these supported workstations. The non-ECC unbuffered DIMM provides a straightforward path to improved multitasking responsiveness.

Speed and latency: DDR4 2133MHz CL15

The single specification that determines fit is the DDR4 2133MHz PC4-17000 CL15 rating at 1.2V. The module must match this exact speed, latency and voltage to operate correctly in the Z240 platform. Buyers requiring ECC error correction or registered buffering cannot use this non-ECC unbuffered part and should verify their system requirements before ordering.

Tool-free DIMM installation

Installation is a tool-free DIY process: open the chassis, align the 288-pin notch with the slot key, press firmly until the retention clips engage, then close the case. The most common issue is the module not seating fully, which causes a no-post condition; re-seating usually resolves it. Systems that require ECC memory will not accept this non-ECC UDIMM.

Perguntas sobre este artigo

How does the 2133MHz speed affect real-world performance in the HP Z240?

The module runs at DDR4 2133 (PC4-17000) with CL15 latency, matching the Z240's native memory bus so the system can use the full bandwidth without downclocking.

What does the PC4-17000 rating actually limit in daily use?

PC4-17000 certifies a peak transfer rate of 17 000 MB/s under JEDEC standard timings; the Z240 memory controller caps sustained throughput at that level.

Will the 288-pin UDIMM fit both the SFF and Tower versions of the Z240?

Yes, the 288-pin unbuffered DIMM matches the standard desktop slot used in both the Z240 SFF and Tower chassis.
