Has anyone heard anything about Zen supporting DDR4 ECC RAM?
I've heard little things here and there but nothing solid or rumours about and mobos.

Most likely all zen chips will support ecc.

Well, technically the last gen AMD could support ECC I believe, however, I have never seen a board supporting it. The new Zen chips could really challenge the Xeon line if they are fully supported with server grade boards. I would love to see some lower price workstations/ servers with zen 8 or 16 core CPUs.
I am pretty sure that the basic 8 core 16 thread zen chip (Summit Ridge or whatever) is going to be the basis for the whole zen line up. The idea behind Zen is that instead of using 2 core modules like Bulldozer, there are 4 core "modules" that are used. Hence the rumors being 8 core, 4 core, and possibly 16 core parts. It is just how many of these modules they include. So from the low end desktop to the high end server stuff, it should all basically be the same. So I wouldn't be surprised if the basic 8 core consumer/enthusiast chip COULD support it. It would depend on the chipset and motherboard, I believe. But I am nto the most knowledgeable about this stuff, so don't quote me (unless I turn out to be right, in which case, I totally knew it).

The server parts will definitely support RDIMMs and UDIMMs, but the desktop line may or may not support UDIMM's like the FX line did in past on AM3+. We don't know anything for or against Desktop UDIMM support, but I think its safe to assume the server chips will support both types of ECC.
i heard that ZEN will support some sort of encryption on the ram will that be a good thing for servers?
That sounds quite interesting. Is that a current tech already? For hyper-security conscious uses, I can see it useful to protect against any viruses that try and directly read RAM. But that is a guess. I haven't heard about that before. I might have to do some reading.
Alot of boards support ECC ram. Most of asus AM3+ line does, a few gigabyte and as rock boards do. And my older biostar boards all did.

think this is the white paper, is basically more advance version of the amd secure platform/trusted platform whatever, where theres an arm core on the die to do this stuff.
but with this they are talking about individual vm/virtualizations having their own individually encrypted memory section(s)with a newer more advance virtualization extension thing
