Testing P2 at + 10% / - 5% voltage specs

Has anyone tested the P2 running at -5 and/or +10% on the voltage rails ?

If not its something we should do in a hurry

    IIRC Chip did some Vcc/MHz sweeps on the manually-cased P2's, but with bench supplies and sparse decoupling caps.

    FWIW the manually packaged P2 runs much hotter at 148.5MHz than the proper packaged Chip at 150MHz.

    The thermal properties of P2D2 and P2-Es boards are quite different though.
