RAM & SSD Installation Troubleshooting Guide

Need some help getting your computer to recognise your new memory upgrade or Solid State Drive?

Don't worry, most people find that the information on this page solves their problem.

Follow an Installation Guide

We have a large library of installation guides here. If you have an Apple Mac computer, start here to find your specific model, and then check the comments section on the right hand side of the page for specific guides on installing RAM, SSD's, batteries etc in your system.

Most manufacturers like Dell, IBM, Lenovo, HP, ASUS and others also publish their own user manuals. Use your favourite search engine (e.g. Google, Bing, etc) to locate the user manual and then follow the guide for installing the hardware you have purchased.

Press firmly and reseat the memory modules

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 so take it out and reseat it again.

Try one module at a time

If you have purchased a pair of modules, try just one at a time. Although faulty modules are rare, to have a pair be both faulty is almost unheard of in our experience. Note even brand new computers, including all Apple computers, can work with just one module installed. (It's not necessary to have a pair installed.)

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. Perhaps it needs plugging back in?

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.

Switch the modules around

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. Server memory systems in particular have special requirements for the placement of memory modules. Search for your user guide using Google for specific instructions.

Did you receive what you actually ordered?

Check that the part number on the merchandise you have received is the same as on your order receipt or invoice.

Fully disconnect the power

In some server systems (particularly Dell) first disconnect the power cord and press the power on/off button to fully discharge the capacitors on the motherboard, then install the memory as normal.

Is it the correct memory type?

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. Use our search function (top of the page) or the Upgrade Finder to see which upgrades specifically apply to your system and check that they match.

Memory mismatch error on boot-up

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.

Update your system BIOS or firmware

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.

Still having trouble?

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 visit the Returns page for more information.
