Memory Module HP DDR4 8GB Single Rank 2400MHz

HP DDR4 8GB Single Rank 2400MHz memory module (MPN: P00918-K21-RFB) is a system memory upgrade designed to improve responsiveness and multitasking on compatible desktops and laptops. This 8GB DDR4 module operates at 2400MHz and uses a single rank configuration to balance performance and compatibility with a wide range of systems. The module is intended for users who need a straightforward memory capacity increase to support demanding applications, light content creation, office workflows, and gaming sessions that benefit from additional RAM.

Advantages

This HP memory module provides a reliable increase in available RAM capacity while maintaining standard DDR4 electrical and timing characteristics. The single rank design improves compatibility across motherboards and laptop platforms that prefer or require single rank modules. With a rated frequency of 2400MHz, the module contributes to smoother multitasking and reduced paging to disk compared with lower-capacity systems. The HP brand and supplied manufacturer part number (P00918-K21-RFB) help ensure traceability and support when verifying compatibility and warranty.

Suitable for

• Upgrading desktops and laptops that support DDR4 2400MHz memory
• Increasing system memory for office applications and web browsing
• Improving multitasking when running multiple applications simultaneously
• Supporting light photo editing and casual gaming where 8GB RAM is sufficient

How to use

Before installing, power down the computer, disconnect power, and follow anti-static precautions. Consult the system or motherboard manual to confirm compatible memory types and slot population rules. Open the memory compartment or access panel, unclip the existing module(s) if replacing or insert into an empty DDR4 slot aligning the notch, and press firmly until the module seats and retention clips engage. Reassemble the system, reconnect power, and verify that the BIOS/UEFI and operating system recognize the full 8GB module. If the system does not boot or recognize the memory, recheck seating, slot compatibility, and whether the platform supports single rank modules at 2400MHz.

Usage recommendations

Install memory modules in matched pairs where the system supports dual-channel operation for improved bandwidth. When mixing modules, use the same capacity, speed (2400MHz), and preferably the same brand and timings to minimize compatibility issues. Keep system BIOS/UEFI firmware up to date to ensure proper memory detection and stability.
