HP Q7720AX-RO 512MB DDR-266MHz PC2100 non-ECC Unbuffered CL2.5 200-Pin SoDimm 2.5V Memory Module

Description

The HP Q7720AX-RO is a 512MB DDR SODIMM memory module designed for older laptop models and other portable computing devices that utilize DDR SDRAM technology. It operates at a clock speed of 266MHz, corresponding to the PC2100 specification, which defines its data transfer rate. This module is intended for systems that are not compatible with newer memory standards like DDR2 or DDR3, providing a means to maintain or slightly upgrade their memory capacity. This memory module is non-ECC (Non-Error-Correcting Code), meaning it does not include hardware-based error detection and correction, making it suitable for consumer-level applications. It is also unbuffered, allowing for direct communication between the memory chips and the system's memory controller, which contributes to its operational speed. The CAS latency is rated at CL2.5, indicating the number of clock cycles required to access data, a common specification for DDR-266 modules. The 200-pin SODIMM form factor is characteristic of DDR memory modules, differentiating them from the 100-pin DDR SODIMMs and the 200-pin DDR2/DDR3 SODIMMs. The specified voltage of 2.5V is also a key characteristic of this generation of memory. This HP-branded module is designed for reliable performance within compatible HP laptops, offering a specific solution for legacy hardware maintenance and upgrades.
