Hello Group

I have an AMD Athlon 1333 on a Gigabite 7ZMMH motherboard.
and it only want to run on 1000 mhz
the motherboard can run up to 1500 mhz.

how can i solve that problem.

MHz to 133 MHz. Your processor (this from memory) defaults to a multiplier =
10, expecting a FSB of 133 MHz. 10 x 133 = 1333 MHz.

Are you sure that the processor is a 1333MHz, and not a 1333+, which
WOULD run at 1.0GHz. :? :?

No such CPU. The slowest in the XP series was the 1500 (which defaulted to
1333 MHz).
That's why I'm sure.

He never said that it was an Athlon XP, it could be a plain athlon, or
or an athlon thunderbird. :wink:

1000 MHz, IIRC) or "Athlon Thunderbird" (topped out at 1400 MHz) that is
not designated for its actual speed. The OP asked about his "AMD Athlon
1333", which is supposed to run at 1333 MHz. It's a common beginner's
mistake to start up a PC for the first time with the motherboard FSB left at
default (100 MHz), thus running the OP's CPU at 1000 MHz (default multiplier
= 10 x 100 MHz = 1000 MHz). The simple (and obvious) fix is to set the FSB
to 133 MHz, thus running the CPU at its design spec: multiplier = 10, FSB =
133 MHz.
Now that you've had your gratuitous history lesson, perhaps you'll realize
that both your comments were implausible and inaccurate.

OK, well no matter what, a 100 MHz FSB is to slow to be anything that
we are talking about, so for the poster, go ahead, check your
motherboard, if it is not already running at 133 FSB, set it to do so.
But be careful, because if you have to set it by way of jumpers on the
motherboard, some manufacturers will label them as 66, 100, and 133
MHz. But in the chip, the frequency gets doubled, thus; 66=133,
100=200, and 133=266. So do a little research into your processor, and
motherboard, mine shows that the Thunderbird 1.33 GHz, has a 266 FSB,
but as I said, please check everything! A 133 MHz FSB processor set to
133 FSB on the motherboard, may double it, resulting in one
hot, and temporairlly non-working processor.

Wait... doubled *and* multiplied by 10 in the chip? I think the doubling
applies to DDR RAM, not to the CPU.

I have a Thunderbird 900.
My old ASUS A7V133 board ran at:
9 x 100 = 900 for the CPU
1 x 100 = 100 _OR_ 1.33 x 100 = 133 for the RAM

My newer Abit NF7 board runs at:
9 x 100 = 900 for the CPU
2 x 100 = 200 for the DDR RAM
