Frequently Asked Questions - DDR4 Crucial

How do I install Crucial DDR4 RAM?

Shut down the system, unplug power, discharge static, remove cover, locate memory slots, align notch with slot, press down firmly until clips snap into place. Use firm pressure (20-30 lbs).

What should I do if my computer beeps after installing new RAM?

Beeps indicate the system may not recognize the memory. Remove and reinstall the modules to ensure they are securely seated. If problem persists, contact Crucial Technical Support.

Can I mix different RAM capacities?

Yes, but fill slots starting with the highest density module in bank 0. For best performance, use matching modules.

Why does my system only recognize half of the new RAM?

This may indicate an incompatibility or improper installation. Check that the module is fully seated. If the issue continues, contact Crucial Technical Support.

Do I need to update BIOS after installing new RAM?

Not usually, but if you receive a configuration mismatch message, enter the Setup menu and select Save and Exit to update settings. Refer to your owner's manual.

How do I discharge static electricity before handling RAM?

Touch an unpainted metal surface on the computer frame after removing the power cable. Avoid plastic surfaces and work in a static-safe area.

What is the voltage requirement for Crucial DDR4 RAM?

Standard DDR4 operates at 1.2V. This is lower than DDR3, improving energy efficiency.

Can I install Crucial DDR4 RAM in a laptop?

Yes, if the laptop uses SODIMM form factor. Insert at a 45° angle and push down until clips snap.

What should I do if the RAM module doesn't fit?

Do not force it. Check the notch position and orientation. Verify the module matches your system's required form factor (DIMM vs SODIMM).

How do I clean my RAM modules?

Use isopropyl alcohol and a lint-free cloth to gently wipe the contacts. Ensure the module is completely dry before reinstalling.

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.

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.
