So I have a asus m4n82 deluxe motherboard with a amd phemon II x3 2.6 Ghz cpu. I was reading that you can unlock the 4th core in this cpu. I know its unstable but I just want to try it. Problem is my motherboard bios doesn't have the Nvidia Core Calibration feature as seen here: http://www.xtremesystems.org/forums... I am not sure what bios version that is but I have the latest one for my board. The pictures in the link above is on the same board as mine. Any one know what bios version that is? and if so were I can download it.

You get BIOS updates from the board manufacturer's website. http://usa.asus.com/products.aspx?m...

I have the lastest version. I know where to get the updates. I just want to know which bios version has that feature. Asus uses AMI bios

"I have the lastest version" Version 0802?

yea 802. I just found out the picture is from a modded bios. So I guess I will just ask the person who put the picture up.

It's not that its unstable in general, it's just that you won't be able to overclock your processor that much without it becoming unstable. With an unlocked core on that phenom x3 your overclocking will prob cap at 2.8ghz stable. The 4th core on the X3 is locked due to one core not passing AMD's thresh hold test which became the faulty core. If you just unlock the 4th core and leave it as is without any overclocking you should be fine, it's when you start overclocking with that unlocked core, that's when you start getting into unknown territory.
