Q: How to start a full RAM diagnostic scan?

In previous versions of Mac we used to be able to hold down the option+D key to do a full hardware diagnostic. In a new iMac running 10.11, when pressing Option+D it seems to run a summary scan within a few minutes but not a full hardware scan? Is there a way to still do this? I'd like to have it test every memory register.

Thanks

iMac, OS X El Capitan (10.11.3)
