    Hi. I have a few questions about some options in my computers BIOS. There was little or no information on google so I am posting on the great BBS! First off, I am wondering what the CPU Ratio Selection does. Its set to 8.0x. The second thing that I don't know anything about is the CPU FSB Clock which is set to 100 MHz. Finally, the last setting in my BIOS is the Clear Extended System Configuration Data which is set to no. Keep in mind that these settings have been this way since I got my system. Will I experience any performance increase by enabling or disabling these options? I know that if it aint broke don't fix it but if someone could shed some light on what these options do then that would be appreciated. :)

    My information is a little dated but I'm sure it's still valid (someone will let you know if I'm wrong ;))

    This is the multiplier ergo the 8.0x eg you have an 800Mhz processor with a 100Mhz front speed bus. 8x100 gives you the 800Mhz. (very slow I know but as I said my info is old hat ;))

    And that's the front speed bus (FSB) I was talking about, it's the engine of your system if you like, it controls how fast your memory runs, how fast your system (internally) can communicate with other devices PCI etc.

    That's a toggle, when you add new hardware it should be triggered automatically (i.e. set to yes), sometimes when your plug and pray (oops plug and play ;)) OS get's confused you turn this on and IRQ's for hardware will be reassigned.

    Either way when you turn it to yes after your next reboot it will be reset to no

    If you're into overclocking then (at a risk) you may experience a faster (IMO far more unstable) system. If you're happy with what you have then as you say "it aint broke don't fix it ".

    Thanks a lot for the info wildfire. So I would only change The CPU Ratio Selection and the CPU FSB Clock if I wanted to overclock my system correct? I think I will leave those settings the way they are since I haven't had any problems with my system and like you said overclocking could cause system instability. So I will play it safe. Thanks for the help! :cool:
