"Driver level errors associated with either the PCI Express bus and/or Nvidia GPUs may have prevented the chips from boosting properly - which was interesting because several reviewers today commented on not hitting advertised boosts. The author observed this behavior on both Gigabyte and MSI boards but only with Nvidia cards and at least for their own work decided it was sufficient enough to warrant not publishing any FPS benchmarks until sorted out."
"This is huge dude, he said he got boost to 4.65 GHz with the older 126.96.36.199 bios, even though PBO did not work on that BIOS. The newer 188.8.131.52 (NPRP press code) & 184.108.40.206AB BIOS were limiting his boost to 4.35 GHz
The driver WHEA errors seem to be unrelated and are a nVidia specific problem. They are probably still causing slowdown in benchmarks."
