Help Needed! Mac Mini Server MC936Z/A (Mid 2011) & Apple Server Diagnostics

[Miscellaneous]

Hey All,

I've just installed 16GB of Crucial RAM into my Mac Mini Server which has all of the latest firmware/software updates. I wanted to run Apple Hardware Test just to make sure everything was OK. So I hold down 'D' at the startup chime only my Mac booted into Apple Server Diagnostics (version 3X109r2). So I performed the test and it has been stuck on the Memory Test 12 for almost an hour and I'm slightly concerned. So here are my questions...

1) Has anyone with this model of Mac Mini have 16GB RAM installed? In particular, Crucial RAM?
2) Has anyone with this model of Mac Mini performed ASD before and approximately how long does it take to complete?
3) Is there anyway to run AHT rather than ASD on this model of Mac Mini? Or should I stick with ASD seeing as that is what is installed on it?
4) What should I do if the Memory Test 12 has crashed or will not proceed? I have already tried to click stop test which has no effect whatsoever!
5) Would it be worth it to put the original RAM back in and run the test again?

I would really appreciate your help with this guys,

Many Thanks.

Quick Update...

It's been around 2 hours and 45 minutes and it's moved on to Memory Test 13 which is a bit of a relief. It's taking a very long time though, compared to AHT. I would love to hear the thoughts of some Mac Mini Server users who are familiar with ASD.

I forgot to mention I'm running OS X 10.10.5 Yosemite on the computer. I'm planning on replacing the boot drive with a 500GB Samsung 850 Evo SSD soon too, keeping one of the 500GB factory fitted HDD's as a data storage drive. So I may need to run the ASD test again just for the SSD, after installation, for peace of mind.

Good News!

The test has now finished after around 6 hours and all of the Memory Tests have passed! I'm now wondering if there is an option to do a more basic test like in AHT.

There are options that can be checked/selected for each particular component being tested but I don't have a clue which one's are the most essential to select.

At least I know the RAM I installed is testing OK. It also shows as 16GB installed on my Mac Mini when using About My Mac.
