My 0x580 had the 66, so it must be that the dodgy > ones got labelled 66 and not all the 0x580s were defective. The original K6-2's off the line where all 100MHz parts, it was later when AMD found that some people where sticking these in 66MHz boards and trying to run them with a 66MHz FSB and having troubles that AMD started to test the parts for 66MHz operation, they had to make some changes in the I/O buffers and then qualify a new part number and those are the ones stamped 66. Aka AMD 6K86-2-P300/66 vs AMD 6K86-2-P300/100 for those who know what a real AMD part number is. To the best of my knowledge no 0x580 stepping 0 chip is qualified by AMD to run with a 66MHz FSB. -- Rod Grimes - KD7CAX - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
