You're lucky that I'm rather an expert at this.
You need:
1x 220K 1/4Watt Resistor
1x (Or 2x I will explain later) Pormona Grabber
1 Piece of wire
1 Soldering Iron and Flux
To find the Pormona Grabbers which allow us to attach the Volt Mod without soldering to our mainboard you need to visit Doctor's Thread -= Get Your Volt Mods Here! =-
Now simply solder the resistor onto the Pormona Grabber, then solder the wire onto the end of the resistor (resistors don't have polarity so theres no right/wrong way round) then this wire MUST go to ground.
This can be done by attaching it to the case with a screw (any Mounting screw will do) or to Pin17 on the Voltage Regulator chip. (This is where that extra Grabber comes in)
Once this is done attach the Grabber to PIN2 shown in red in the picture.

This chip is located at the top right of the Mainboard as shown here:

Luckily with the 8KHA+ you don't need a variable Potentiometer to adjust the voltage.
Simply select 1.65V in the BIOS for 1.9V and 1.85V for a maximum 2.1V.
Just remember that this mod will make a lot more heat, so Watercooling is preffered over 2V.
Also a good PSU is needed to take the extra current, so if your 5V line drops to low you may wish to take a look at Hoot's thread Why is my 5V so low? Read this
I have also done this Mod so if you need any information gimme a bell.
Good Luck!

Thanks for your great answers.
I'm totally down today. The heatpipe arrive and I wanted the CPU to be save and used a cu-spacer. After power up there was only blank screen. I powered instantly down and checkt the CPU. But it had gone already .....
I swear I will never use a spacer again .....
I get a cheap AXIA 1GHz TB soon, so meanwhile my Duron does the work. When I got the TB I will try the mod ...

The AXIA is the best stepping for a Ghz T-Bird, they have been known to go as high as 1.8Ghz!
Realistically there's no reason why with 2.1V you can't hit 1.4Ghz.
My AVIA (slightly worst stepping) hit 1.6Ghz
Good Luck!

I really hope for 10 or 11x133, but well, we'll see it when it arrives.
I coulf bit myself, because of my 1.1B. It was - or still is - an AXIA and took even 1.6 GHz .... without volt mod and water-cooling.
My system's in a CS-601 with 3x80mm fans. I used a Alpha6035 with an adapter to attach an Enermax PL80B with potti.
Too bad for the Tbird.
Do you think I can send it to AMD for replacement? There's no damage to the DIE. Only a little dark on one point of the waffer.

I don't think AMD would but you could try.
Simply email there tech support state what CPU you have an say it failed during operation, and don't mention overclocking!!!
Or simply return it to the place of purchase, I would try to get the black mark off it though, its a bit of a give away
Good Luck with your new chip,

I wouldn't sell it on ebay, unless you sell it for $10 as a keychain.

Got the 1 GHz AXIA today. Just plugged in and it works fine @10x140 with 1.80 Vcore. Maybe tomorrow I will unlock it and try 10,5x140 or 11x133 with max. Vcore .....
I use the Coolermaster Heatpipe with standard fan @7volts, so it's okay with the noise.
I really like the AXIA stepping ;-)
But why wouldn't you try to sell the 1.1B via ebay - it's burned, so where could be a loss? Or do you know somebody who can repair it? ;-)

I meant don't sell it saying it works, but MAKE sure you say its BROKEN.
Hence the keychain.

lol doubt it.
Just don't sell it as new, you'll have some unhappy customers!!!

Very nice,
with lower temps you will get 1.6Ghz, and with 2.1V you'll get 1.8Ghz no fooling!!

Yes, but how to lower temps without getting too much noise. I have a CS-601st with 2x 80mm fans blowing in and 2x 80mm fans blowing out (all @~9volts).
Also there's a 431w enermax and the coolermaster heatpipe with a papst 3.7W 60mm fan on it (@~7-8volts)
I don't think air cooling could give me much better temps, even if I would buy an alpha 8045 or Swiftech 462 ...
I bought the heatpipe because of it's famous cooling @5 and @7 volts .... or what do you mean?
I think I will wait 2 months and plug the 8KHA+ in the 2nd pc and buy then a cheap 8K3A+ with Vcore up to 2.2V

You have good temps so do't worry about it,
I just meant with H20... (sly grin)
