Hi.
I just built this system as well, and would like to ask what the "unlock" does? I am trying to find videos to learn how to "manually" set my own parameters, but I am hearing so many people having RAM troubles and BIOS issues. Right now I just am using the Automatic overclock feature and for me I am happy with 3.2xx GHz. The RAM I got is Corsair 16GB QV listed @ 1600, they are set just slightly lower than their highest (or course).
But, unlocking sounds like you can have all processors/chips running at full potential speed. I saw a video where a guy has a Gigabyte board and goes in and changes his NB and such. Even this is too new for me, I've never heard of the North Bridge stuff until now. It's been two years since my last build but never messed with over clocking.
I only got one 120mm fan on and my system temp is at 46 degrees with the over clock on. Right now I have no problems and still have the 08xx BIOS version on, I think there is a newer one that came out one month later, but if it ain't broke don't ....!
Wow. 4.1 that's really pushing it!
