test memory upgrade

[skasol]

what software do you recommend to test my hardware with a new memory upgrade. I sent my computer to applecare and they deemed my upgrade 16GB memory to be an issue with my computer so they replaced it and put the apple memory back in it. I have a 2011 cMBP i7 2.0

Thank you in advance.

Hold the D key at startup, it will get you into Apple Hardware Test where the memory is tested.

Other ways are rember and memtest86.

What brand do you have, corsair has quite a few problems and is mentioned lots of time here on MR, Crucial is much better.

Corsair vengeance. When I hold D nothing happens. I tried a few times it just boots to the desktop. Any tips?

Hmm, I though a 2011 had Apple Hardware Test build into the OS, guess not, if you have Installer disks use that.
If you read the Link I gave it tells you more about it.

I don't have installer disk. I upgraded to mountain lion.

That's an advantage of retina models. Only Apple memory is soldered in. No chance for errors.

That's good. Thanks for the observation.

Don't just press and release it, hold it until you see it gets into AHT, but if this does not work I am out of ideas, oh, actually not, do you have a wireless keyboard, if so it has known bugs in OS X 10.8.2, key strokes not registered at startup, the way around it is to press the Power key on the wireless keyboard shortly, then hold the D key.
(I haave the same problem on my Mini)

You can actually test if you have this issue, if you hold any other startup shortcut and it does not work you know it's not registering.

Edit: Forget it, it's a MBP

That's odd, as you can read in the link Apple says D key only.

But, you got it so it doesn't matter.

Option D allows you to do it over the net.

Never heard this, but I guess you're right.
