Overclocking - beyond the BIOS

The only method of o'cing with which I familiar is changing FSB/DRAM speed in the BIOS. Would anyone be willing to give me a overview of the other methods out there and/or more through BIOS?
 
You can also increase the cpu multiplier if your cpu is unlocked. My understanding is that most (if not all) Intel processors are locked (which means you can't change the multiplier), but if you have an AMD XP processor (Thoroughbred core and up), they come unlocked. That means that you should be able to change the multiplier setting using the BIOS. However, it really does depend on what mobo you have and if your BIOS is oc friendly. I own an Abit NF7-S mobo and the BIOS allows me to change multiplier settings from 7x all the way to 16x in 0.5 increments and FSB settings from stock 133MHz all the way to 250MHz in 1 to 2 MHz increments. Now, just being able to change these settings doesn't mean that you can oc your system as high as u want. You need to find a combo that gives you oc and stability.
 
You can also physically mod the chip and/or the motherboard to force a speed change on _some_ motherboards that don't have BIOS or jumper settings to do so.

Here's my guide for doing this with socket 370 and socket 478 CPUs. Note that you may also have to do a voltage mod (search for "wire trick") to make this stable at the boosted speed.

Socket A chips can also be modded through connecting/cutting various "bridges" on top of the CPU. There's probably some guides out there already for that.

I did the FCPGA Celeron 600MHz to 900MHz with that modification (66 to 100). You might want to update the page that it works 🙂
