How to use
Before installation, power down the computer, disconnect power and ground yourself to avoid electrostatic discharge. Open the desktop chassis according to the manufacturer instructions, locate the appropriate DDR4 UDIMM slots on the motherboard and align the module notch with the slot key. Press firmly and evenly until the module locks into place with the retention clips. Reassemble the chassis, reconnect power and boot the system. Verify that the operating system and firmware recognize the new 16GB module and that total installed memory matches expectations.
Usage recommendations
Install memory in matched pairs when possible for dual-channel operation if the motherboard supports it; consult the motherboard manual for supported configurations, maximum memory capacity and supported frequencies. Ensure BIOS/UEFI is updated to the latest recommended version for best compatibility with new memory modules. If issues arise after installation, reseat the module and test with a known-good slot or run memory diagnostics.
