Problem with athlon 2500 and a7n8x-x

[RyuRobD]

When i boot up the system, it posts at 1100 mhz (despite the fact that the jumper is set to 266/333/400 mhz fsb) and says "Warning!! CPU have been changed!" and will not allow me to enter the BIOS. Any ideas? System setup is:

Asus a7n8x-x
Athlon 2500+ Barton
Soundblaster Live Value
Geforce 2 MX
Maxtor 80 GB w 8 MB cache
Norcent 52-24-52 cd-rw
Pacific Digital 16x Dvd-rom
Generic 400 W PS
512 MB Crucial PC2700 C2.5

i get that message all the time but it always lets me enter the bios to change it to the right speed.

clear CMOS and see if u can enter the BIOS

Clear your CMOS, then boot.

😉 You may also need to update the mobo BIOS ... and that dusty GF2 if you plan to game with that rig!
