I have a intel celeron 667 that fits into a socket 370.I noticed in bios that when I do the page up page down I can adjust the settings to 700 mhz 66/133 is that as far as I can go on the motherboard or is that overclocking the cpu to the max I can go?If I can overclock it by that much what do I have to do in order not to have a burn out?

You cant just adjust the settings for 700Mhx on a 667, as all Intel CPUs are core locked, the only way you can overclock these, is to change the FSB speed, at the moment, your celeron is running at 66MHz, and you can only change it to 100MHz, depend on your board, memory, and other hardware installed, this may work, or may not.

So I can adjust it in bios to 700mhz without having a burn out?now will I have to buy a different fan?and does this mean that my cpu will be running at 700mhz now?and what is core locked?

No, because the CPU are locked in the core, even if you change the option to 700MHz, when you power on, the CPU will locked and still run at 667MHz. You cant change the speed without changing the FSB speed (which is 66MHz now, and the other option is 100MHz, but when you do, you will be over clocking this CPU by such a great margin, it may not run).

Darn it!!!!!!!!!!!! ok so how do I go about changing the front side bus?

Depends on your motherboard, let us know make/model

It's a Alton mainboard V605A.It says in the manual that it supports FSB speeds of 66mhz,100mhz and 133mhz.I bought it from MilwaukeePC about 4 months ago.

A cpu's speed is determined by 2 factors cpu multiplier (which in your case is locked) and FSB you have a multiplier of 10 and a FSB of 66Mhz 10x66=660Mhz which is approximatly the speed of your cpu. If your Motherboard only supports a FSB of 66Mhz, 100Mhz or 133Mhz and not any speed's inbetween then if you bump the FSB up to 100 you will have a cpu running at 1000Mhz (10x100=1000) which will be pushing the cpu to far. But if your Motherboard supports speed inbetween such as 75Mhz 83Mhz etc. then you be able to overclock. And also you have proberly got 66Mhz RAM so if you bump the FSB over 66Mhz your memory might not be able to handle it so it will not be stable or not run at all.
