HP 4M9Y2AA 32GB DDR5 4800 U non-ECC UDIMM 288PIN content_copy

This product is a memory module from manufacturer HP, type MEM, with manufacturer number 4M9Y2AA. It is a DDR5 module with a memory capacity of 32 GB, designed as a UDIMM (Unbuffered Dual Inline Memory Module). The module is designed for use in PC / Server systems and features a 288-pin DIMM form factor. The memory clock speed is 4800 MHz, enabling high data transfer rates. The module is non-ECC (Non-ECC), meaning it does not provide error correction and is intended for applications where high speed and capacity are prioritized, and critical error resilience is not required.

Applications
This module is suitable for professional workstations and high-performance PC systems, particularly in environments where large data volumes are processed, such as 3D rendering, video and image editing, simulations, or other memory-intensive applications. It is specifically designed for systems such as the HP Z6 G5 A Workstation Desktop PC, which supports up to 1 TB of DDR5 memory. The high clock speed of 4800 MHz supports fast data access, which is important for smooth workflows with demanding software solutions.

Features and Specifications in Detail
The module provides a memory capacity of 32 GB in a single module (1 x 32 GB), enabling simple installation and expansion. The use of DDR5 technology ensures higher bandwidth and efficiency compared to previous memory standards. The clock speed of 4800 MHz supports fast data transfers, which is particularly beneficial for applications with high memory requirements. The module is designed as a UDIMM, meaning it connects directly to the system’s memory slot without additional buffer or register components.

Technical Explanation
The term DDR5 stands for Double Data Rate 5, a memory technology that transfers data in both phases of the clock signal, thereby increasing bandwidth. The clock speed of 4800 MHz describes the rate at which data is transferred, with higher frequencies generally leading to faster access times. The 288-pin DIMM form factor is the standard for desktop PCs and servers, ensuring compatible connection to the motherboard. The module is non-ECC, meaning it does not offer integrated error correction and is suitable for applications where high speed and capacity are more important than error resilience.

Compatibility and Accessories
The module is designed for systems that support DDR5 memory with a 4800 MHz clock speed, particularly for the HP Z6 G5 A Workstation. It is designed as a UDIMM, enabling direct connection to the motherboard. Compatibility with other systems depends on the motherboard specifications, particularly support for DDR5 and the maximum clock speed. It is not intended for ECC systems, as it does not provide error correction.

Installation and Mounting
Installation is performed by inserting the module into an available DIMM slot on the motherboard. The 288-pin connector must fit precisely into the slot, with alignment ensured by a notch in the module and the slot. After insertion, the module is secured by pressing the retention clips on both sides. Installation requires no additional tools or components.

Operational Advantages
The module offers a high memory capacity of 32 GB in a single module, simplifying installation and expansion. The clock speed of 4800 MHz supports fast data access, which is advantageous for performance-intensive applications. The use of DDR5 technology ensures high bandwidth and efficiency. The module is designed for systems requiring high memory speed without the need for error correction.
