Cascade Lake Xeon W processors

I have asked SuperMicro, why the Xeon W cannot work on the server motherboards. Gave me something about Intel requiring a certain type of firmware on a "server" motherboard and the "workstation" processors needing another type of firmware. Nothing in the hardware to limit this. Just a decision. Intel won't answer me either. I am very very very pissed about this. I am a home server hobbyist, and I NEED AVX-512. The prices on their SP processors are ridiculous. Not hobbyist money. Let's say I chose a Xeon W-3245. 16 cores @ 3.2 GHz. There isn't ANY SP setup that can do that. I want a medium amount of threads but a higher clock speed. I wanted to go from my Xeon W-2140B (8 cores @ 3.2 GHz) to something like I just mentioned. 4k video even with AVX-512 is still slow, and I'd like to halve my workload times. This being said, I refuse to go AMD on this end, because they don't have AVX-512. Trying a Ryzen on my desktop and I'm not even digging that. What can I do to get some answers on this? This just seems like an attempt to block the hobbyist. I detect a lot of snobbery when it comes to civilians using real server-grade hardware that isn't 15 years old and long obsolete. The Skylake-W processors had full "server" board support. And to add, no I can't get a workstation board in a server chassis. The RAM slots are oriented 90 degrees from what is in a server board.

Well when have the Xeons ever worked on consumer chipsets? That I can understand. When you have server boards with C621 chipsets and workstation boards with C621 chipsets, it's just plain ignorant that they don't allow this to work, with the excuse of "security."

A few? They work on X99, X79, X58 and with some mods can use on Core 2 lol. I think this new series is first one that vendors have not put in code for them.

The vendors tell me it's a limitation set forth by Intel. This is what I'm trying to get to the bottom of.

I wonder if any of the more consumer-oriented motherboard manufacturers (ASUS, Gigabyte) may work.

"It’s the limitation by Intel. The motherboard supports Intel Xeon W-3200 series CPU must use ME client firmware according to Intel POR. However, all servers motherboards must use SPS firmware to support Skylake SP & Cascade SP CPUs."

That's the spiel I got from SuperMicro. BUT the workstation boards everyone makes support the SP processors just fine.

W and SP are different sockets though 2066 and 3647 so I wouldn't expect them to support each other.
