Frequently Asked Questions - DDR3L-1866 Crucial

How do I install the Crucial DDR3L-1866 RAM?

First, ensure you are in a static-safe environment. Shut down your system, unplug power, and remove the battery for laptops. Discharge residual power by pressing the power button. Touch an unpainted metal surface to ground yourself. Locate the memory slots, align the notch on the module with the slot, and press firmly until the clips snap into place. For SODIMMs, insert at a 45° angle and then push down. Refer to your system's owner's manual for specific instructions.

What should I do if my system does not boot after installing the memory?

Check that the modules are securely seated in the sockets. Remove and reinstall them if necessary. Also verify all internal connections, as cables may have been bumped loose. Ensure the power supply is connected. If problems persist, contact Crucial Technical Support.

Why do I get a memory mismatch error after installation?

This is not an error; some systems require updating the configuration settings. Enter the Setup menu (usually by pressing F2 or Del during boot), then select 'Save and Exit'. This will update the system settings to recognize the new memory.

What if my system only recognizes half of the new memory?

This could indicate a compatibility issue or a defective module. First, try reseating the module. Ensure you are using the correct slot (usually bank 0 for the highest density). If the issue persists, contact Crucial Technical Support for assistance.

How do I protect the memory from static damage during installation?

Work in a static-safe environment free of plastic bags or papers. Before handling the module, touch an unpainted metal surface on your computer's frame to discharge static. Always hold the module by its edges, avoiding the gold contacts.

Can I mix different memory modules with the DDR3L-1866?

Mixing different speeds or types (e.g., DDR3 with DDR3L) may cause instability. For best performance, use identical modules from the same kit. If mixing, the system will operate at the speed of the slowest module. Check your motherboard's manual for compatibility.

What tools are needed to install the memory?

Typically, no tools are required. You may need a non-magnetic-tip screwdriver to remove the computer cover. Do not use tools to insert the memory module; it should be installed by hand with firm, even pressure.

How do I remove an existing memory module?

First, power down and unplug your system. Ground yourself to prevent static damage. Locate the memory slots. Gently push the clips on each side of the module outward; the module will pop up. For SODIMMs, spread the clips and the module will release. Lift the module out by the edges.

What is the voltage requirement for DDR3L-1866?

DDR3L operates at 1.35V, which is lower than standard DDR3's 1.5V. This reduces power consumption and heat. The memory is backward compatible with 1.5V slots, but will run at the lower voltage if supported by the motherboard.

USER MANUAL DDR3L-1866 Crucial

Install Guide

General Memory Module Installation

Equipment needed

• Memory module(s)
  • Non-magnetic-tip screwdriver (for removing the cover on your computer)
• Your system's owner's manual

Installation process

1. Make sure that you are working in a static-safe environment. Remove any plastic bags or papers from your work space.

2. Shut down your system and make sure the power is completely off before unplugging the power cable from your computer. For laptops, then remove the battery.

3. Discharge residual power by pressing the power button.

4. Remove your computer's cover. Refer to your owner's manual for how to do this.

5. To protect your new memory modules and your system's components from static damage during the installation process, touch any of the unpainted metal surfaces on your computer's frame before handling and installing memory.

6. Using your system's owner's manual, locate your computer's memory expansion slots. Do not use any tools in the removal or installation of memory modules.

7. Insert your new memory module(s) in accordance with the illustrations in this guide. Align the notch(es) on the module with the notch(es) in the slot, and then press the module down until the clips on the slot snap into place. (It can take 20 to 30 pounds of pressure to install a module.) Fill the memory slots on your computer starting with the highest density (i.e. put the highest density module in bank 0).

8. Once the module(s) have been installed, replace the cover on your computer and reconnect the power cord or battery. Installation is now complete.

Desktop, server, and printer memory installation (DIMM modules)

Using firm, even pressure, push DIMM into socket until clips snap into place. Do not assist clips.

Laptop memory installation (SODIMM modules)

Firmly push SODIMM in at 45° angle, and then push down until clips snap into place.

Helpful hints & troubleshooting tips

If your system does not boot, check the following:

1. If you receive an error message or hear a series of beeps, your system may not be recognizing the new memory. Remove and reinstall the modules to ensure they are securely seated in the sockets.
2. If your system won't boot, check all of the connections inside your computer. It is easy to bump a cable and pull it out of its connector, disabling devices such as your hard drive or CD-ROM. If your system still won't reboot, contact Crucial Technical Support.
3. When restarting your system, you may get a message prompting you to update the configuration settings. Refer to your owner's manual for information. If you are still unsure, please call Crucial Technical Support for assistance.
4. If you get a memory mismatch message, follow the prompts to enter the Setup menu, and then select Save and Exit. (This is not an error—some systems must do this to update the system settings.)

If you encounter any of the following problems, please contact Crucial Technical Support:

1. Your module doesn't seem to fit; do not force it into the socket.
2. Your system is recognizing only half of the new module's memory.
