HP 13L77AA 8GB DDR4 3200 U non-ECC SODIMM 260PIN content_copy

HP 8 GB DDR4-3200 SODIMM (manufacturer number 13L77AA) is a memory module for laptops and small desktop systems, specifically developed for use in HP Business PCs. It is a SODIMM module with 260 pins, designed for use in compact computers such as Small Form Factor or Microtower systems. The module offers a memory capacity of 8 GB and operates at a clock frequency of 3200 MHz, enabling high data transfer rates. It is implemented as DDR4 memory, representing the current standard technology for high-performance, energy-efficient memory. The module is not ECC-enabled, which is sufficient for use in standard and business systems without error correction.

Applications
This module is specifically intended for a range of HP desktop and Small Form Factor systems, including the HP 280 G4/5 Small Form Factor, HP 280 G5/6 MT, HP 290 G3/4 Microtower, HP ProDesk 400 G6/7 Small Form Factor and Microtower, HP ProDesk 600 G5/6 Microtower and Small Form Factor, as well as HP EliteDesk 705 G5 Small Form Factor and HP EliteDesk 805 G6 Small Form Factor. These systems are typically used in office environments, home offices, or small businesses where a stable and high-performance memory solution is required. Compatibility is limited to the specified models, with exact fit and electrical interface ensured by the respective motherboard circuit board.

Features and Equipment in Detail
The module features a 260-pin SO-DIMM form factor, optimized for notebooks and small desktop computers. The 8 GB memory capacity enables simultaneous use of multiple applications and processing of larger data volumes, which is particularly beneficial for office applications, web browsers with multiple tabs, or light multitasking. The clock frequency of 3200 MHz ensures fast data transfer between CPU and memory, improving system responsiveness. The memory architecture is designed for use in Dual-Channel systems, which can double the theoretical bandwidth when two identical modules are installed. This results in reduced system latency and improved overall performance.

Technology Explained Simply
The DDR4 memory type is the fourth generation of Double Data Rate technology and offers higher speed and lower power consumption compared to older generations. The clock frequency of 3200 MHz means the module can process 3.2 billion data cycles per second, ensuring smooth system responsiveness. The SODIMM form factor is a compact memory module type specifically developed for devices with limited space. The 260 pins ensure a stable electrical connection to the motherboard. The module is not ECC-capable, meaning it does not perform error correction for memory errors – this is sufficient for use in standard and business systems, as ECC memory is primarily required in servers or critical applications.

Compatibility and Accessories
Compatibility is limited to the specified models, with exact electrical interface ensured by the respective motherboard circuit board. It is not intended for use with other manufacturers or systems. Use in a Dual-Channel setup is possible if a second identical module is installed, increasing bandwidth. No specific accessories are included with this module; installation is direct into the system’s memory slot.

Installation and Mounting
Installation is performed by inserting the module into the appropriate memory slot of the HP system. The 260-pin connector must fit precisely into the slot, with alignment ensured by a notch on the module and the slot. After insertion, the module is secured by pressing the retention clips on both sides. Installation requires no additional tools and can typically be done without disassembling the system, provided the memory slot is accessible. The exact mounting instructions are described in the respective HP computer’s user manual.

Operational Advantages
Using this module results in improved system performance, especially during multitasking and simultaneous use of multiple applications. The high clock frequency of 3200 MHz ensures fast data access, resulting in shorter boot times and smoother system responsiveness. Compatibility with the specified HP systems ensures stable and reliable operation. The module is designed for use in office environments and home office systems, where sufficient memory capacity and performance are required without the need for special error correction features.
