    Default CPU multiplier in A64's how high...

    What is the highest anyone has seen a stable Athlon 64(FX or not) multiplier?
    Mine runs 11 stock but I have the options from 5x - 25x.... I know that it would never work at 25 but how high have you guys seen them stable?

    Please also say what socket, what core(if known), and what model... E.g. 2800, 3000, 3200, 3400, etc...

    Only Athlon 64 FX's are unlocked for higher than stock multipliers, and theyre not known for their overclocking ability

    I know I was only asking what people have seen these processors' multipliers run at, no more.

    Curiosity mainly.

    Ive only seen them 1 or 2x above normal multiplier on air, with extreme cooling (water or compressor cooling system) you could get 4x higher but im guessing thats the upper limit

    Damn it the option is there for CPU multiplier Manipulation but it won't let me get over 11... sould have been smarter than that... DUH the multiplier is locked via hardware on the chip... Damn it why do I have to be so powerhungry. Hehe.

    A friend of mine got his FX-55 to almost 3 gHz on air so they're pretty overclockable. With a chilled water cooler I would think around 3.1-3.2 gHz. With a phase change cooler probably close to 4 gHz.

    Then id like to see how the upcoming FX-57 on a 90nm process overclocks....

    That could be a while. I'd say Q2 2005 at earliest for the FX57. What might be interesting is the 90nm 3800 which may come out Q1 2005. I wouldn't worry about having a partially-locked multiplier, because you can just put a divider on the CPU and RAM and overclock the base clock and HT, or "FSB," and not really lose much performance. Having faster RAM for athlon 64s is nice for overclocking and will performance better, but it's not a necessity. You can gainfully overclock an Atlhon 64 with a top-locked multiplier and PC2700 RAM and not even touch the RAM speed.

    Overclocking via fsb, or hypertransport in this case, is more effective. If you have 2 processors running at 2 gHz, one at 20x100mHz and one at 15x133, the second one will perform slightly better.
