why the heck do motherboars have 83mhz fsb setting if there is no real use for them because the pci bus is out of wack. and whats the differnece between the FSB and the system bus

batboy said:Front Side Bus (FSB) and system bus is the same thing. Some components can run at 83 MHz if they are high quality, exceptional parts. But, you're right, it's often right on the ragged edge of instability. Why that was a standard motherboard setting, I don't know. Need to ask the design engineers.

It is all for the Celeron's. They run at 66Mhz stock and they don't really go to 100Mhz to well. I know I ran my 400Mhz Celeron @ 500Mhz for a while at 83Mhz. It does run on the edge of instablity, but It got the job done. I know that the system is no longer willing to run at that speed again.

No it's not for the Celerons. The 83 Mhz FSB was out way before the Celerons. The 83 Mhz FSB was made for the Cyrix. It was the first CPU to break the 66Mhz barrier.
6x86MX-PR266 = 208MHz = 83*2.5I know some Cyrix CPUs ran at 75 MHz FSB, but I don't remember any defaulting at 83 MHz FSB.
