I recently purchased an AMD Athlon Thunderbird system (FIC AZ11E motherboard, 1.1ghz Athlon cpu, 256mb PC133 DIMM). The system works fine, except for one problem: when I set the frontside bus speed jumper to 133mhz (choices are 133mhz and 100mhz) the system will not power on. If I set it back to 100mhz it works fine. Has anyone else experienced this? Any ideas what might cause this problem?

Just for starters, do you have PC133 memory?

that would set the processor to 1466mhz! no way without some serious subambient cooling, raising the core voltage and possibly the io voltage. overclocking should be done in babysteps :-) http://arstechnica.com/cpu/ http://users.erols.com/chare/hardware.htm http://www.sysopt.com/overc.html http://www.hardwarecentral.com/hardwarecentral http://www.hardocp.com/ http://www.lostcircuits.com/ http://www.tweak3d.net/ http://homepages.tig.com.au/~mozz/OVERCLOC.HTM http://www.sharkyextreme.com/ http://www.cpu-central.com/ i've overclocked dozens of processors and the only 1 i ever fried was a 1.1 tbird after changing the sink from a crome orb to a super orb. the sink was not on straight and wasnt making good contact with the slug even with heatsink compound. took all of about 30 seconds to turn it into a keychain fob :-(
