AMD 2600 running at 1243 mhz

I just bought and built a shuttle SN45G with a AMD 2600 CPU.
Everything went well except (big except) my AMD 2600 is running only
at 1243 mhz. That is the speed that is being recognized by the
computer and by the AMD utility that is suppose to tell you the speed
independant of any bios issues. Any ideas. Is there something I
shoud try or did I get a bad CPU.

Thanks

Go into the BIOS setup and into the advanced settings, you should see
something that will allow you to change the input clock to a higher speed.
If it's supposed to run at 133Mhz, then it may be running at 100Mhz,
instead. If it's supposed to be running at 166Mhz, then it may be running at
133Mhz instead. So try and bring up the input clock speed one setting
higher.

My guess is that the BIOS is simply setup slightly wrong. Your CPU is
likely a 166MHz (333MT/s DDR) bus speed chip, that is designed to run
with a multiplier of 12.5 (for a CPU clock of 2083MHz, the speed that
at least one model of AthlonXP 2600+ runs at). Chances are that your
BIOS is defaulting to using a 100MHz bus speed rather than
auto-detecting. Go into your BIOS setup and change the bus speed to
either 166MHz or to auto-detect and you should be all set.

Thanks, that was exactly the problem.
