Need checklist for testing 2020 iMac (memory, screen..) before return period ends

[mindquest]

Waiting on a new 2020 27" iMac and wanted to know what should be stress tested before the return period ends.

I know I should test the memory and screen for dead pixels but what else? Any other things I am missing?

Also what software can you use to test the screen for dead pixels?

And what software does everyone recommend to test the memory?

Thanks in advance!

You can use the built diagnostics to test the RAM.

Hold D upon boot. And if you want to run the extended diagnostics, once the first round finishes, press CMD+E.

Any ideas on software to test the screen?

Techtool Pro has a lot of tests, including some simple screen tests.



But why are you worrying about it? If there is a problem it would be fixed under the standard 1 year warranty, even longer with AppleCare.

Thanks for that! Will check it out!

I stress test all my electronics out of the box and return if they don’t perform. Why spend money on something that isn’t 100% right out of the box. And that is not even factoring the time and potential lost productivity waiting on a repair or replacement.

Used the free version of https://www.memtest86.com/ and it did a great set of intensive tests.
