I purchased 4GB (2x2GB) from Crucial a few years ago and have just discovered that both of the two modules are no longer recognised (DIMM shown as empty). Is there any ttrick to possible get them to work again, or is it just a write-off?

The memory modules you purchased from us are under a limited lifetime warranty. If they do prove to be defective we would be happy to set up a replacement and RMA for you. There are a few memory tests out there you could run to determine if they are defective. These are links to the free memory testers:
For the Mac OS, a popular tester is Rember, which can be found here:
Set Rember to test “All”, and check the box next to “Infinite” number of loops, and let the test run for at least half an hour. Since Rember is running from your desktop, it's important that you shut down all applications before you run the test. If you have any programs open, the test will be a lot less accurate.
If you are needing a RMA please contact us at:

The modules in question are not being recognised at all. I have moved them around and they are still not being recognised as the slots come up as empty so the problem has to do with the modules themselves. The test does not seem to bring me much further since the modules can not being tested when not being recognised.

What is the processor speed and year of the iMac that you are you installing the RAM in? In most systems if you install a speed lower than recommended it will just run slower with no repercussions. However, in some Apple systems the RAM has to match all the same specs or you will run into issues. Issues that you may experience would be it running slowly or not functioning properly. All issues would be resolved when you remove the RAM and install the proper speed of RAM. Please let us know if you have any further questions about this upgrade.
