I can't buy a used cpu from an SGI US customer and put it in an SGI EU motherboard. I can buy a new CPU from anyone though, but then I can only sell it in-region.

Correct, but that's less a region thing and more this just poisons all used CPUs.

As in you don't even know if an SGI US CPU will work in a different SGI US motherboard. There's no particular reason to assume all SGI US motherboard models will have the same signing key. Within the same model that'd almost certainly be the case, but if it's a different model, especially different chipset, I don't know why they would necessarily strive to keep the key the same across different firmware branches.

Er, why? Nothing about this stops you from re-selling CPUs however you want. Or are you still talking about the used market here?

I'm not reselling a cpu without plugging it in and testing it. If it's DOA when my customer got it, and I didn't test it, I need to take it back etc. Of course, if it gets locked when I test it, now it's more likely to be DOA for my customer.
