i7-875K - which board / BIOS?

[n00b32]

Hello,

according to German Magazine c't this CPU needs a special BIOS

http://www.heise.de/newsticker/meldung/ ... 09800.html

Not only has the BIOS to provide the option to change core frequency, multiplier and core voltage but also multiplier for Turbo-Boost according to used cores:

Basistaktfrequenz, Multiplikator und Kernspannung bietet, sondern auch Zugriff auf die Multiplikatoren für die verschiedenen Turbo-Boost-Stufen – je nach Anzahl der aktiven Kerne – gewährt.

Are there any Gigabyte BIOS out there with this?

Gigabyte post beta BIOS with support for 875K CPU.

Have not had any time recently to explore, but I'm wondering if the recent change to the BIOS slash screen:
viewtopic.php?f=14&t=1504&p=13636&hilit=unlocked#p13636
adding the "UNLOCKED PERFORMANCE" banner has anything to do with this?

The only special BIOS I know about is Asus's new incorporation of having the user be able to control the new Core i series' turbo boost. Basically that means that you can set the turbo boost and how fast you want it to be. For example:

i7-875K - 2.93 normal clock; 3.6 turbo-boost (I'm making this up)

You can then set the BIOS so that:
All 4 CPU's maxed out: normally 3.2, BIOS setting up to 3.4
Only 2 CPU's maxed out: normally 3.45, BIOS setting up to 3.6
Only 1 CPU maxed out: normally 3.6 with turbo boost, BIOS setting up to 4.2

That's all I know about a special BIOS built for the unlocked series.

Just loaded the F11c BIOS for GA-P55A-UD4P:
F11c 2010/06/18
Beta BIOS
Improve Intel Turbo Boost compatibility

and had a quick look through the M.I.T. settings - nothing struck me as new there. Hopefully have more time to play with this 875 soon.

No change to Geekbench or Cinebench scores.

From what I heard they are internal changes.
