i recently bought a new amd athlon 2800+ /w barton core for my soyo mobo. it says on the site that the mobo will support up to a 3000+ with 333 fsb. i installed the chip and tried to boot up but it said "unknown chip @ 1250 mhz." it gave me a long beep and then proceeded to shut down. do i have to buy a new mobo, or flash the bios or something to get it to recognize this chip?
