Have any of you guys had issues booting with over 1.1V QPI on F7E?

Setting everything at stock and only changing QPI to just 1.12V, it won't post. It fails at 26 on the debug LED.

Also, is there anyway to change memory timings from within Windows with SB? CPU-Tweaker doesn't work. And finally, is there a way to change BCLK within Windows? Easy Tuner doesn't have a slider for it.
