    I didn't reply, because he already had. His link seemed to meet your needs

    He wasn't. I copied this from his previous reply a couple of days ago.:)

    I don't know why you didn't see it before.

    You ever hear the old saying about honey catching flys better than
    something else? I honestly didn't think you were serious about needing
    help with this. I assumed you already knew about the mod since it was
    discussed here some time back. And I also know you're quite capable of
    doing it. Good luck.

    That model number isn't listed on the Jetway site. They also have their
    manuals in a proprietary .doc format. So I'll make some assumtions.
    I assume it's a KT133A chipset and not the KT133 (non A).
    I'll also assume that you have memory capable of running 133MHz (PC133 or
    Also that you have at least a 300w PS minimum.
    make sure the cpu you buy is not one of the newer locked versions (post
    week 0338) unless you would be happy with a 2400+ from 2000-2175MHz.

    Any cpu should boot as long as your board/bios doesn't support multiplier
    changing. It will boot with the default multiplier x FSB speeds. That
    means that any that have a FSB of 133Mhz should boot to default speeds. If
    the cpu's default FSB is 166 or 200, it will only run at a slower speed
    until you manually change the multiplier. This is why you don't want one
    of the newer internally locked cpu's with a 166/200MHz FSB.

    Any Palomino core should run without mods since it's multiplier locked and
    only uses a 133MHz FSB. You can unlock any of these unless your board
    supports bios controlled multiplier changes. If this is the case, then you
    can't unlock the 2100+ Palomino core cpu. It won't work since it will try
    and default to 2000MHz (20x100) and it won't run at that speed.

    The same applies to Tbred A cores as Palominos, except they are all
    unlocked from the factory AFAIK. This means that you'd have to mod either
    the MB or cpu before you could get anything over a 2000+ to work.

    Any Tbred B core should boot out of the box. From 1700-2000+ they should
    boot to there default speed. 2100-2600+/266 should boot at 2000MHz
    (20x100) out of the box.

    Unlocked Bartons 2500-2800+ & 3200+ should boot at slower speeds, and you
    have to mod them to get top speed.

    Unlocked 3000+/333 should boot at 2000MHz (20x100) since it has a default
    multiplier of 13 (8x bit high).

    And now for my picks. Easiest would be a 2100-2400+ unlocked Tbred B
    core. These will all default to the same speed (2000Mhz) without mods to
    anything or they will default to default speeds depending on multiplier
    control of your MB.

    For a barton, I'd chose the 2500+ (pre week 39). change the default
    multplier to 13 (making it a 3000+).

    Now, if you haven't read my site, do so. if you have any other questions,
    ask. Be specific.
