Will Epyc work in a TR4 motherboard?

Maybe i'm misinformed from the web but i thought AMD was using 2 slightly different sockets for Threadripper (socket TR4) and Epyc (socket SP3)?

Now you have me confused. Guess were all gonna have to google around. I dont know if there is any diff?

The sockets are not compatible, though they are physically similar.
Blast!
ThreadRipper and EPYC are different. One has two dies, the other has four. The sockets are also incompatible down at electrical level.

one has quad channel DDR4 the other has 8 channel DDR4, should of been obvious enough.
Both have four dies. On Threadripper, only two of them work.
EPYC has four dies. Threadripper has two dies plus two spacers. It is reported in several sites now. It is also reported in the link that I gave you above.

Probably a better chance TR would work on an Epyc board though I would not try it. I would watch it on YouTube though!
Hopefully there is some keying to prevent either way from happening or perhaps some clever wiring that keeps the CPU powered off if its in the wrong socket.

Its literally the same die. There are many ways the SOC functionality could be disabled - everything from laser cutting the die to a simple bit in the firmware. The less drastic measures could be bypassed with a suitable board. I think people ran dual socket Celerons back in the day so not completely unheard of.

The old BP-6 from A-bit. Had one, killed it trying to mod it for P3s. Ah the creamy smoothness of SMP back in the day.. Now a days might as well get the board you need for the platform. i doubt we will see any jury-rigged trans-platform boards. Stranger things have happened.
I can bet you, SP3 and TR4 are physically same socket, but they are different at electrical level.
So tell me, why that Celerons didn't work on Slot A motherboard? It was exactly same slot...

An Intel proc on an AMD board? No one would expect that unless it was advertised as an Intel compatible chipset.
TR and Epyc, on the other hand, are the same processor and could work in the same boards if AMD wanted them to (like Intel made dual channel Kaby Lake work on a quad channel X299 board) and/or clever enough modders get involved. Not guaranteed to happen but certainly not impossible until we know enough to rule it out. Really someone would have to compare the pinouts of SP3 vs TR4 very closely
There was nothing creamy smooth about the BP6. I wanted it to be so much more than it was.
There were no W2K drivers for my Creative sound card. No USB support in Windows NT. No SMP support in Windows 98. Unstable with dual CPUs overclocked.
Having said all that, I still loved it. *Tear
