32gb ram not working

Is it possible to have a current (late 2013, version 14,2) iMac work stably with 32GB of RAM?

I think not, after reading for over an hr, the many complaints and posts on a multiplicity of forums. I, myself have spent about 8 hrs trying this, and so far the conclusions (subject to change based on new info, of course) are:

• the new iMac's seem to work well with most DDR3 SO-DIMMS, that are specced for 1600MHz and timing of 11-11-11
• both 1.5V and 1.35V ram works ok
• BUT do not use the full 32GB storage, even though that is what Apple advertises as max allowed

I, and others, have found for example that if you have 4x 8GB memory sticks, ANY 3 will work, but if you add the 4th then the iMac will seemingly randomly reboot. This can happen within a couple of hrs, and it doesn't matter if the Mac is stressed or idle, or even asleep.

What I find most dissapointing is that Apple has never, to my knowledge, admitted this problem, nor stated that they are working on a fix.

I have now put my iMac back to 24GB, using 2x 8GB and 2x 4GB memory sticks.

I know that people are unlikely to post that something IS working, but if anyone has an iMac 14,2 working on 32GB ram for over 48hrs without rebooting, I would love to hear from you.

Meanwhile I suggest, save yourself the headache and cost of trying to max out the ram, and risk loss of work by the reboots!

And have a nice day!
