Josh, I'll know soon enough about height clearances. Will take lots of pictures. I think there is room however in the M100. A socket on the M100 board is a mandatory so you can revert to normal operation. So, worst case is that the card itself has no sockets, but has the 2 CPUs soldered in place. Best case, socket on motherboard and sockets on the CPU card.
You'll see when I post photos that the board extends to where the RAM modules are also, so clearances are going to be tricky. ..Steve On Thu, Jul 11, 2019 at 11:14 AM Josh Malone <[email protected]> wrote: > On Thu, Jul 11, 2019 at 10:31 AM Stephen Adolph <[email protected]> > wrote: > > > Board is done and heading to the fab.
