Hi Paul
Worked this out a last.
The motherboard had the PLAO_FREQ (FID0/1/2/3) set to the PALOMINO
setting and not the Athlon setting. I changed this and it picked the
CPU settings up fine.
I am playing with the speed on the board, 16.5 x 140fsb (1.56volts)
giving 2.31ghz. Will have to keep an eye on it to make sure im not
running it too fast, but so far it seems ok.
Thanks for all your help, great forum, will def use again....!!
