Product Description
The HP Q7720A-RO is a 512MB memory module designed for laptops and other portable computing devices that utilize Small Outline DIMMs (SoDIMMs). This module is based on DDR (Double Data Rate) SDRAM technology and operates at a frequency of 266MHz, corresponding to the PC2100 speed rating. The 200-pin connector is standard for DDR SODIMMs, ensuring compatibility with a wide range of older laptop models and compact systems. This particular memory module is specified as Non-ECC (Error-Correcting Code) and Unbuffered. Non-ECC memory does not have built-in error detection and correction capabilities, which is typical for consumer-grade laptops and desktops where the cost and complexity of ECC are not required. Unbuffered memory directly connects to the memory controller without an intermediate register, which is common in smaller form factor devices. It operates at a voltage of 2.5V. With its 512MB capacity, this memory module was suitable for upgrading older laptops or systems that required additional RAM for basic computing tasks. While 512MB is a modest amount by today's standards, it was a common configuration for many systems from the era when DDR memory was prevalent. The Q7720A-RO serves as a replacement or upgrade component for specific HP or compatible systems that require this exact specification.
