    Bios F4's, this "TDP limit" is apparently turned off, just like you can disable speedstep, so that turbo enabled is practically giving you +1 multi, so you will need more vcore to be stable. If this is a hidden setting in bios, (at this point I would think it has to be), I wish GB would let us turn it on or off, ie make the setting visible....though I guess we can by changing bioses...There are pluses and minuses to both ways.
    I agree control over that feature would be very cool it opens things up for 920 users if this is possible I would hope all the manufacturers would make this option available.. So actually you get a 21 multiplier all you have to do is enable turbo for 21 and disable for 20 that's great actually.. I don't see a negative side to this what so ever...

    P.S. I finally stabilized the 920 at 4.0Ghz on the P6T Deluxe I will post some pics in a bit after I prime for a few more hours but I got 3 hours of prime95 in now and it looks like it's finally stable..

    I got another record concerning low voltage:

    3.7 1.16V 4 threads, very much stable.

    Prime 95 almost 6 hours.

    nope its not a GB thing, if the cooling is good enough you get the 21 multi on every board.

    Yeah, I read about it some time ago, but I was not really able to find a proof for it. Stressing more than 1 or 2 cores/threads, multi's gonna drop - was all peeps were reporting, iirc. But I remember seeing results of a fixed turbo mode in some of the gigabyte testing threads first.

    Wow, at only 1.2V!
    Nice one. What stepping, if I may ask...

    I'm priming it 4Ghz at 1.25V. It boots at 1.20V no problems runs a little and suddenly freezes. I need to adjust some settings.

    You won the lottery, 8 threads 4.0ghz at 1.20V.

    How many minutes priming so far?

    An update and the maximum I could get stable with 8 cores at 4.0Ghz.

    1.27V was my best shot.


    1.20V

    i am shocked at all the posters trying to overclock and having very frustrating results with high temps...of course, anytime you are 1 ghz over default speed, on air, is doing very good in my book!

    So it's rather these bad Core i7 chips, not the motherboards that are the bottleneck at the moment?

    Any ETA on new chips?

    These are not bad chips by any means, 50% overclock on every chip is just amazing.

    +1

    I did not expect nehalem to overclock more than 3.5Ghz on air to be honest.So these clocks are trully amazing, making the upgrade worth it in my opinion.
