First off, you will need to find a 2B pencil. While a standard 2B pencil will do, a 2B Mechanical Pencil saves a lot of time sharpening. And yes, I know it sounds ridiculous but all you need is a pencil! (hence the name :P). 2B pencils are best to use because they have a high graphite content which means the lead will conduct electricity well enough for this to work. If you can't get or don't have a 2B pencil then try and find the closest type you can.
Now make sure the pencil is extremely sharp! Sit there for 5 minutes or so sharpening the pencil so you can get it as fine as possible! (That's if you didn't go the intelligent way of using a mechanical pencil :P) Believe me, the way I'm about to show you needs it to be a fine point!

Now remove your HSF, undo the ZIFF retention socket and take out your CPU. Clean off all thermal goop so as to remove any visual obstructions. This may also be a good time to write down your CPU stepping and batch codes for later reference. If you look VERY closely you will see four sets of four small copper traces. These are set side by side. Beside each set of four you will notice it says L1, L2, L3 and L4. The ones we are interested in are the L1 set.

If you have a magnifying glass then you can take a closer look and will notice that the L1's aren't joined. They are cut by laser at factory, locking the multiplier. But when they are joined the multiplier can be changed. Yep, you guessed it! We're going to join them up.

Now grab that very sharp pencil (now do you see why I said it has to be sharp?) and go up and down each L1 bridge carefully. Be sure not to join two of the bridges that are side by side. If you do accidentally join them up, just grab an eraser and start again. Simple as that! Now once you're happy with the final result and looks something like this:

Now you'll have to re-apply some goop. This will make your temps lower, allowing a higher overclock. The best way to do this is to grab an ID card or something of the such, put a tiny bit of goop on there and wipe it lightly over the bottom of the HSF. Try and get the thinnest layer you can. Put the CPU back in and put the HSF back on (of course).
