Asus Also Announces Non-Z Overclocking on 8-Series Mobos

Previously, a number of manufacturers announced the option to overclock K-series Haswell CPUs on non-Z series motherboards, and now Asus has joined in as well.

In the past, typically there were two requirements for overclocking CPUs with the use of a multiplier. You'd need a Z-series chipset on your motherboard as well as a K-series CPU. Now though, it appears that a bug in the 8-series chipsets allows users to overclock Intel Haswell K-series CPUs on non-Z series motherboards, allowing for overclocking on budget motherboards. A K-series CPU is still required though, as non-K series CPUs have an upwards locked frequency multiplier.

Of course, to make use of the feature you need a BIOS update, which can be found on Asus' website. Motherboards that support the feature include the H87-PRO, H87-PLUS, H87M-PRO, H87M-PLUS, H87M-E, H87I-PLUS, B85-PRO, B85-PLUS, B85M-E and B85M-G.

    Nothing groundbreaking here... Monkey see, monkey do...

    Cool, great for people looking for marginal OC with budget.

    In other news: Intel CEO Paul Otellini has just killed the CEOs of Asrock, Biostar, Asus, Gigabyte, and ECS for "exploiting him and butchering his annual income."

    in other news, cpu price increase to compensate low revenue in other "areas"

    mass confusion going on here with these changes.
    is this a way mobo manufacturers are getting back at Intel because they are progressing
    (future reference) to an everything on-chip platform limiting the mobos from having a full set of features like in older boards.
    so just let almost every board starting now 'open-up'..?

    sorry guys but the future the SOC and ARM is growing and that's bad news for desktop enthusiast..

    I wonder if Intel is going to fix this in the next chipset stepping. Hope not.

    I read somewhere that H-series mobos couldn't handle OC'ing. Was that guy crazy or not?

    Also, is this worth paying the extra $40 or so for a K-series CPU?
