2. Compatibility
This memory kit is specifically designed and guaranteed compatible with the following Acer systems:
- Acer Altos BrainSphere P10 F7 SFF
- Acer Altos BrainSphere P10 F7 Tower
- Acer Altos BrainSphere P130 F7
Ensure your system is one of the models listed above to guarantee proper functionality. A 64-bit operating system is required to utilize more than 4GB of memory.
3. Installation Guide
3.1. Preparation
- Power Off: Completely shut down your computer and unplug all power cables from the wall outlet and the computer.
- Grounding: Discharge any static electricity by touching a grounded metal object (e.g., the unpainted metal part of your computer case) before handling the memory modules. Consider using an anti-static wrist strap.
- Tools: A Phillips head screwdriver may be required to open your computer case.
3.2. Installation Steps
- Open Case: Carefully open your computer's side panel to access the motherboard. Refer to your computer's manual for specific instructions on opening the case.
- Locate Memory Slots: Identify the DDR4 DIMM slots on your motherboard. These are typically located near the CPU. Your system has 4 sockets.
- Prepare Slots: If there are existing memory modules, gently push the retention clips on both ends of the slot outwards to release them. If the slots are empty, ensure the clips are open.
- Insert Modules: Hold the new memory module by its edges, avoiding touching the gold connectors. Align the notch on the module with the key in the DIMM slot.
- Seat Modules: Apply firm, even pressure to both ends of the module until it clicks into place and the retention clips snap shut. Ensure both clips are fully closed.
- Repeat: Repeat the process for all four memory modules.

- Close Case: Once all modules are securely installed, close your computer's side panel.
- Reconnect Power: Plug in all power cables and peripherals.
- Power On: Turn on your computer. The system should automatically detect the new memory.
4. Operating Considerations
Upon the first boot after installation, your system's BIOS/UEFI may take a moment to recognize the new memory configuration. Allow the system to complete its POST (Power-On Self-Test) process. You can verify the installed memory amount in your system's BIOS/UEFI settings or within your operating system's system information.
For optimal performance, it is recommended to install memory modules in matched pairs. All memory in the system will operate at the slowest performance of the installed modules or the CPU/processor capability.
5. Maintenance and Handling
- Always handle memory modules by their edges to avoid touching the gold contacts or the components on the module.
- Store unused modules in anti-static bags to protect them from static discharge and dust.
- Keep memory modules away from extreme temperatures and humidity.
6. Troubleshooting
- System Does Not Boot / No Display:
- Ensure all memory modules are fully seated in their slots and the retention clips are closed.
- Verify compatibility with your specific system model.
- Try installing one module at a time to identify a potentially faulty module or slot.
- Incorrect Memory Amount Detected:
- Check your system's BIOS/UEFI settings to confirm the detected memory.
- Ensure your operating system is 64-bit to utilize more than 4GB of RAM.
- Re-seat the modules to ensure proper contact.
- System Instability / Blue Screens:
- Run a memory diagnostic tool (e.g., Windows Memory Diagnostic) to check for errors.
- Ensure your system's BIOS is up to date.
