    It's a Gigabyte problem. The current BIOSes don't disable turbo properly. Toggle turbo on and then back off in AMD Overdrive and it'll quit until you reboot.
    Particle's First Rule of Online Technical Discussion:
    As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.

    Rule 1A:
    Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.

    Rule 2:
    When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.

    Rule 2A:
    When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.

    Rule 3:
    When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.

    Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!

    You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.

    This isn't just an Gigabyte issue. My Asrock 990FX does this as well as do other boards I've seen around the net.

    I suppose I should rephrase. It's a motherboard manufacturer problem, not an AMD problem. Some boards disable turbo correctly and some don't. Fixes will come in the form of new BIOSes.

    We can always dream that a good BIOS fix will come down the pipe soon....right I gotta wonder if allot of AMD boards BIOS updates aren't in limbo right now with the clock interrupt error that supposedly, a BIOS update will cure? It will take AMD a "month to work out a BIOS fix", but who the heck knows what is actually going on? I'd say AMD has their hands full with a batch of faulty chips and simple fixes might take a while to get done? Like I say though, who knows

    I have to wonder how many people are affected by this issue and how many other people fail Prime at higher frequencies, and if this failure is architectural or just programs that don't understand the new chip?

    AMD isn't writing the BIOS for your board. That's the responsibility of each individual motherboard design team. Thus if you have a Gigabyte board, it's a Gigabyte problem. If you have an ASUS, it's an ASUS problem (which isn't an issue I suppose since ASUS's boards such as the CH5 do it correctly already). Also, I'm not saying a BIOS update will come later and fix it, just that a fix would come in that form if a fix is eventually fielded.

    You have to disable APM master. AFAIK Gigabyte mobos still haven't had this option in the BIOS.

    Thanks Fatbird , this bios are good , has the APM option, I disable it. (and uninstall phenommsrtweaker that I use for fix with old bios)
    I test hyperpi and linx , multiplier not drop.
    and cpu bus not shift (old bios set cpu bus 200 mhz in bios, but real bus are 201.3 mhz)
    thanks again and thanks everyone in this thread for information.
