FAQs
Is this memory compatible with laptops?
No, this is a 288-pin DIMM module designed specifically for desktop computers. Laptops require smaller SO-DIMM form factors.
Can I use this with my existing memory?
Yes, provided your motherboard has available slots and supports the same DDR4 standard. It is recommended to match speed and latency ratings for optimal stability.
Do I need to configure the BIOS for this memory to work?
This module is designed to work at standard JEDEC speeds, so it should be recognized automatically by your system without BIOS intervention.
Does this module support ECC?
No, this is a non-ECC, unbuffered memory module intended for standard PC and server use.
What does the 'CL19' mean?
CL19 refers to the CAS latency, which is the delay time between the memory receiving a command and executing it. Lower numbers are generally faster, but CL19 is standard for 2666 MHz DDR4 modules.
Troubleshooting
System fails to boot or beeps during startup
Ensure the module is fully seated in the DIMM slot. If the issue persists, try placing it in a different memory slot to rule out motherboard port failure.
Computer does not recognize the new 4GB memory
Verify that your motherboard BIOS supports 2666 MHz DDR4 memory and perform a BIOS update if necessary.
System crashes or experiences blue screens
Run a memory diagnostic tool to check for hardware errors; if errors are found, re-seat the module or test it independently to confirm if the stick is faulty.

Setup, Compatibility & Care
To install this module, ensure your computer is powered off and unplugged. Open your desktop chassis, locate the memory slots on your motherboard, and align the notch on the memory module with the key in the DIMM slot. Press down firmly until the side tabs snap into place. Before purchasing, confirm that your motherboard supports DDR4 memory and 2666 MHz speeds; it is not backward compatible with DDR3 slots. When handling the module, avoid touching the gold contact pins to prevent oil or debris buildup, which can cause connection issues. Always use static-safe handling techniques during installation.
