Vcore should go up with Prime. Sounds like you're stuck in power saving mode.
I'm using the shipped BIOS and I do have the EIST & C1E turned off, but I left the 'Thermal Protection" option enabled.
But yeah, it's bizarre; I was running Prime last night and just shut it off - while it was running it appears to have gone as high as 1.34v, but has now dropped to 1.3v...but the VID in the BIOS is 1.35v.
