Computer Memory Installation and Troubleshooting Tips

Need some help getting your computer to recognise your new upgrade?

Don't worry, most people find that the information on this page solves their problem, or you can go back to the Returns page.

Press firmly

Make sure the notches in your module are lined up with the keys in the slot, and then press firmly. Memory modules are designed to fit snugly, and it can take more force than you might think to click into place. The clips on the side of module should snap into place on their own. If you have to move the clips into place by hand, your module isn't installed properly.

Try one module at a time

If you have purchased a pair of modules, try just one at a time and try to replicate the issue you've been having. Although faulty modules are rare, to encounter a pair of faulty modules in the same order is almost unheard of in our experience. Note, all modern computers, including Apple brand computers, will accept just one memory module at a time, even though they might have come with two installed from the factory.

Operating System limitations

It may not be a hardware problem - it could be limitations of your operating system. Learn more about hardware and Operating System limitations.

Re-insert the power cord

If you followed one of our installation guides, you likely removed the power cord before installing the new upgrade hardware. Perhaps it needs plugging back in? Back to the top ↑

Remove any dust

Dust, dirt, carpet fibres and other debris can affect electrical conductivity. Use a fine brush, vacuum cleaner or hand blower to clean the sockets thoroughly.

Check the internal cables

We find it is quite common for one of the wires or cables (especially in desktop computers) to become slightly loose during the process of installing a memory upgrade. A loose hard drive cable can prevent your computer from booting up properly. Make sure all the cables are firmly connected at both ends.

Use a memory testing utility

Every module we sell is factory tested for proper compliance and operation. There are two programs we know of that can be used to do a more extensive test of the modules. For mac users, we recommend Rember and for PC users we recommend Memtest.

More installation tips

• Make sure that you are working in a static safe environment. Make sure the area where you're working on your upgrades isn't full of other static-inducing components. A bare table is best. Keep plastic desk accessories, wastebaskets, and telephones away from your work area.
• One of the worst creators of static charge is a rolling desk chair (unless you have a specialised anti-static chair mat). Push it away, and stand up when you're working on your PC. Make sure to keep your computer plugged in but with the power turned off at the wall. Keeping your PC plugged in will keep the case grounded, thus reducing the chance of damaging the module or system. Touch an unpainted metal part of your case before touching your new modules or any other components in your system. Back to the top ↑
• Remove and reinstall the module(s) to ensure they are seated securely in the socket.
• Fill the memory slots in your computer starting with the largest density and working to the smallest (put the largest module in slot 0, and the second largest in slot 1, and so on). Some systems go in reverse order, so if this doesn't work, try reversing the procedure.
• Check that the part number on the merchandise you have received is the same as on your order receipt or invoice.
• Check that your new RAM is the same type as your old RAM (i.e. SDRAM/DDR/DDR2/DDR3, ECC/Non-ECC, buffered/unbuffered). Incorrect or mis-matched memory can often result in a blank screen and no POST (power on self test), or a BIOS/CMOS setup error.
• If you get a memory mismatch error follow the prompts to enter setup, then select save and exit. (This is not an error — some systems must do this to update their CMOS settings.) The POST may also pause until you press F2 or another key as displayed on the screen to accept a change in memory configuration.
• If none of the above helps, and your computer is a few years old, it may need a BIOS (Basic Input Output System) update in order to work with current memory module technology. Visit your computer or motherboard vendors website to see if they have a new BIOS version. Installation is usually simple if you follow the instructions. We recommend that you backup your data before proceeding with a bios update.
• If your system is only reading half of the new module's memory, or you are still having problems after trying all of the above, then contact our Customer Service Team for assistance.
