Asus has released a new BIOS for their Asus Maximus Extreme IV P67 Motherboard that moves the Multiplier Cap from 57 to 59 on Intel K series CPU's. It also adds extra stability for Overclocking. Since they raised it from 57 to 59 this means that for everyone's chip that can handle it a 6.0 ghz overclock and higher will now be able to be obtained. Here's the link.... since I know a decent amount of TPU members has this board. I thought it might be cool to post here.... http://www.asus.com/Motherboards/Intel_Socket_1155/Maximus_IV_Extreme/#download The link above is to just pick your OS and then choose version 1303. I don't know if they did this update for other motherboards or not. But it might be worth looking into.
