HP DDR4 Module 4 GB DIMM 288-PIN 2133 MHz PC4-17000 CL15 1.2 V unbuffered non-ECC for Workstation Z2

The HP 4GB DDR4 2133MHz memory module is a single 4 GB DIMM designed for desktop PCs and compatible servers. It uses DDR4 technology with a 288-pin DIMM form factor and runs at an effective clock speed of 2133 MHz with a CAS latency of 15. The module’s black and green appearance reflects HP’s reference styling while providing a compact memory upgrade that supports everyday multitasking, application responsiveness and system stability when added to compatible motherboards that accept unbuffered DDR4 DIMMs.

Advantages

This 4 GB DDR4 2133 MHz module delivers a balance of capacity and power efficiency compared with older DDR3 modules, reducing overall system power draw while offering improved data transfer rates at the specified clock. The 288-pin DIMM physical design ensures broad compatibility with motherboards that support standard DDR4 desktop memory, and the CAS latency of 15 provides predictable, low-latency operation for common office and home workloads.

Suitable for

• General-purpose desktop PCs requiring a low-cost memory upgrade
• Office workstations running productivity software and web browsing
• Home systems for media playback, light photo editing and multitasking
• Servers or compact systems that explicitly support unbuffered DDR4 288-pin DIMMs at 2133 MHz

Key specifications

How to use

Power off the computer and disconnect it from the power source before installing the memory module. Open the system case to access the DIMM slots, consult the motherboard manual to identify the correct slot configuration, and align the module’s keyed notch with the slot. Firmly press the module into the slot until the retention clips engage. Reassemble the case, reconnect power, and start the system. Verify the new memory is recognised in the BIOS/UEFI or operating system system information tools.

Recommendations

Install modules in matched pairs when possible to enable dual-channel operation on motherboards that support it. Check the motherboard or system documentation for maximum supported memory capacity and supported memory speeds; when mixing modules of different speeds or sizes, the system may default to the lowest common speed.
