Just watch that Motherboard jam the cpu clock speed as well.
Im using the same one and its complete pants with any bios ive used.I aint used 1504 but i have been told its golden so maybe i will but i need latest oprom for raid trim too
So yea keep an eye for funny reboots and the cpu clock speed or bios settings being changed on the fly.I have had a small exe error in windows and it took my 4700mhz OC down to 3800 IN WINDOWS without a reboot and i had to reset cmos to clear it.your bios might still read 4700mhz etc but its a lie and cpu-z will show you the real clock speed.
Unless it jams at the preferred overclock you want ie for me i need it to jam at 4700 then its complete pants.I really hate that motherboard atm.
And LLC should be high on Asus,ultra high and extreme actually reverse vdroops so it goes up instead of down so LLC high should be all thats needed alongside say PLL 1.65 and voltage 1.3.You should get 4400 out of that at least and the lower PLL will take temps down even though 70C aint bad at all.
