This is my first build... I finally got my OEM 1.2ghz 266fsb Athlon-c and got everything set up w/ my KT7a-RAID. I powered up for the first time and my CPU auto-detected at only 900mhz!!! wtf!?!? Did i get ripped on a bum CPU? I went further in the BIOS and manually set it up to run at 1200mhz/133fsb... but shouldn't it have detected it at that in the first place? I'm worried, did I pay for a 1.2ghz and get a 900mhz just because it was OEM!? Please help, thanks!

have you updated your bios? If it was indeed at 900mhz and you switched it to 1200mhz @ 133fsb it wouldn't run so I think your ok there. Sound like your missing a bios update to support 133fsb cpu's without oc'ing.

I haven't gotten to update anything yet, everything is straight out of the box... Is there a BIOS update that is supposed to fix this (if that is the problem)? Also, could it still be a possibility that i got screwed? heh, I'd like to eliminate any fears as soon as possible here. thanks again.

I think by Default KT7A mobo runs at 100MHz DDR FSB (or 200MHz). That's why it detected your CPU as 900MHz (Multiplier 9 X FSB 100MHz = 900MHz). Just in case, you can check the marking on its die. It should be A1200XX ... 'something'.
This link shows you the die of an Athlon 1300MHz (A1300AMS3<b>B</b> ). If the last letter of your CPU is <b>C</b> indicates that's the Athlon 266MHz FSB

I just found an interesting article from Anandtech describes issues when using KT133A chipset mobos.

oh yeah, i knew it was marked as a 1.2ghz Athlon-c, but i heard some rumors that some OEM chips are low-quality rejects from the factory and eventhough it was marked right, i thought i might have gotten royally screwed, heh. But thanks to all of yall! I'll be sure to get that BIOS update ASAP! :)
