I was hoping that it was a BIOS-bug, but that hope is fading fast. I fear you may be right, so far I have seen 3 MB (GB Ud5, UD7 and your EVGA) with locked Uncore at x20.

Yeah VVT=1.5v sounds right for BCLK215 and x20 Uncore, but Intel is recommending max VVT=1.4v for these CPUs. It is .5v more than i7-920 which has survived with VVT=1.45v+ easily, but I'm a kind of scared to try high VVT for 24/7 before I get to know these CPUs a bit better.
Good to see yours have survived 1.5v
