Yes you can set the ai overclock tuner to manual, sync all cores and set the cpu core ratio to46 and scroll down and enter 1.30v in the cpu core voltage override. F10 and Enter to save and exit.
Download rog realbench for stress testing and real temp 3.70 for cpu temp monitoring.
http://rog.asus.com/rog-pro/realbench-v2-leaderboard/Open up real temp and realbench click on stress test, turn it white and select how many GB of ram you have, the 15 minute test is fine.
Click start and monitor your temps if the temp goes over 90c stop the test.
If you pass the test go back into the bios and just raise the cpu core ratio to 47 and test again if you pass try 48.
Post your temps please.
