Hi @jfra,
I asked the layout engineer about this and they let me know that the each of the 8 holes have the same diameter of 3.658 mm.
I think the reason the holes are marked differently on the mechanical file is that some of them (which you marked in blue) don't have the copper(?) ring around the mounting hole.
Let me know if you have any questions.
Thanks,

Hi @jfra,
The Genesys ZU does not have an option to be shipped with ECC memory as you correctly read; the only ECC memory that I know of that was specifically tested would be what it was validated with as mentioned in this post here:
Let me know if you have any questions.
Thanks,

Hi @jfra,
I'll have to get back to you on exact dimensions (presuming you still need them), but for the 8 circled locations the Genesys ZU (both variants) comes with the following standoffs and screws:
M3 6 mm steel screw
M3 10 mm nylon hex standoff (F/F)
In the interest of being thorough:
The Zmod A has:
M2.5x0.45 5 mm tall aluminum hex spacer (F/F) on each side of it on the top side of the board
M2.5x0.45 10 mm tall nylon hex spacer (M/F) on each side on the underside of the board
The FMC LPC has:
#4 M2.5 10 mm tall aluminum hex foot (F/F) on each side on the top side of the board
M2.5x0.45 10 mm tall nylon hex spacer (M/F) on each side on the underside of the board
The Mini PCIe has on the top side:
M2 1.0 mm tall (Ø4.35x2.4mm) standoff on all four slots
M2x0.4 3.5 mm tall standoff (M/F) on the "back" two slots
M2 screw with a 4 mm head 3 mm in length on top of the standoffs present on the "back" two slots
Let me know if you have any questions.
Thanks,
JColvin
