Technically according to Dell and Crucial specs, a 32 GB RAM module is not compatible with the T3610. 8 RAM slots with a maximum of 16 GB per slot for a total of 128 GB of RAM. 

I was afraid that it might be something like that, thanks. 

I bought my T3610 from a company and it arrived with 4x8gb dimms, one expired after 6 hours, so they couriered 2x16gb dimms to me as a replacement. One of those was faulty straight away. So then they sent out 1x32gb dimm. And that one gives the error. I questioned the whole 16gb dimm max but they said that they had tested it in a T3610 with A19 bios and it worked. So I that I would ask the community and see if there was a solution 

The PSU failure is with a flashing power button and 1+3 led. I know that a solid white power button and led 1+3 is memory detected but unsupported, but with Bios A19 update the other T3610 is working fine with the single 32gb dimm. So I was wondering if there was some other setting that I needed. 

This is getting interesting

This site selling rams, certifies even 64gb modules, for the 3610. and according to them, 512gb can be installed.

Ah, so the test wasn't done in a way that you could see it.. but it's the word of the seller.

In this case, it adds the extra option of "maybe they are lying"

Maybe the 2 computers have a different revision of the motherboard. Older revision is not working and newer is (this is just an idea, you could check the motherboard revision/code using hwinfo , or sysoft sandra, or other tools )

There is always that, but I got the big boss involved as this has been going on since the 12 April. And he seemed fairly unhappy that they had not resolved the problem. They have a pretty good reputation, one of the reasons I chose them. Anyway they are going to collect my machine and either fix it or replace it. But the time delay is frustrating. 

You cannot mix speed, density,  rank and vendors and ECC vs Non ECC

The other issue is the exact CPU in the machine.

Yeah I saw that too in my quest for answers. But I will question the seller about board revisions and see if that played a part in the elusive 32gb dimm, will post the results when I have more answers.
