ASUS X99 PRO - In the new 3505 BIOS, all CPU Power Phase controls are broken. If reverts to "Standard" regardless of whether you set Optimized, Extreme, or any of the Manual Settings (regular to very fast). I then installed AI Suite so I could see the current power state and also try to influence it from the program. Same results: All standard, all the time. Flashed back to 3402 and all is normal again with full control over all BIOS settings. This is the third time for the 3402 -> 3505 flash, so I am comfortable ruling out an update error. This was done on the Optimized Defaults, save the Power Phase and setting my water pump to run at 100%. I then repeated it all with my standard overclock, where I am more familiar with all of the VRM temperatures for the various phase settings.
It's kind of hard to believe this slipped through the testing protocols on all of the internal versions 3501-3504 and now the public release. If this is deliberate, we need a slightly more elaborate explanation than the normally very thorough update notes.
