How do you use the little codes on them to tell what ones overclock best?? AND where to get a 1ghz thunderbird that is the best week for overclocking and not have to pay $250+?

From <a href=http://www.bensbargains.net>Ben's Bargains</a>:
<i>There will be a price drop by AMD in the coming week. I'm telling you because I just bought one for $260. No biggie.

$200 for a 1GHz chip will be great!</i>

From what I've seen so far, no one's OCing the 1ghz T-bird much past 1.2 ghz effectively (stable) with the highest Abit KT7 voltage setting of 1.85v on that mobo so gaining 200 mhz seems to be about the fastest I've seen. You need to close the L1 bridges and what I did was use automotive defroster grid repair paint rather than the pencil trick. Pencil lead is a VERY poor conductor. Soldering would be best and I've done alot of soldering but I can't imagine trying an area that small (high risk factor too).
There's another method of soldering a resistor to the mobo to get more cpu voltage but IMHO it's just not worth the possible risk and probably won't get much better than another 50mhz. At 1.2 ghz, what's 50mhz anyways?

So will pretty much all 1ghz thunderbirds do 1200?

I don't see why not?
Here's a link I found from yet another site called Pauls KT7 FAQ
http://go.to/kt7faq
and it seems to be mostly about OCing AMD cpus.

It seems as though some guys are getting the 1 ghz T-bird to 1.3mhz but mine isn't yet doing that and I'm not sure I care to try pushing it.

Most SocketA's will do 200 Mhz over rated core frequency with a voltage increase and decent air cooling. With water cooling you get more. Of course there will be execptions.
The 200 mhz is with changing the multiplier. I unlock them by soldering the bridges. I also solder the bridges for the the multiplier setting. I have the right equipment to do it so I might as well.

The resistor you add to mess with the voltage on the Asus is on the regulator board that is sticking up. I also would only play with this if you know what you are doing as this "fools" the circuit to output more voltage but it will not be read in the bios so to know what you have you have to use a voltmeter.

Saturn,
"I unlock them by soldering the bridges. I also solder the bridges for the the multiplier setting"
-isn't this the same thing, connecting the 4 L1 bridges or are you doing something more? If so, I'd like to know more about it.
My mobo is the Abit KT7-Raid and I've seen the topic on how to add a resistor to it to increase voltage but I have doubts I'd even notice another 100mhz if it did work. I also don't own a soldering iron with a tip small enough to solder anything like those L1 bridges but that'd no doubt be the best way to close those connections.

Evil,

No, not quite the same thing. Some boards don't have any multiplier adjustments so I not only solder the L1 bridges but I have to cut and solder the bridges for the multipliers which are l3,l4,l6 and voltage L7. Once you are up to 900Mhz the only way I can tell is the benchmarks. 100 mhz isn't worth screwing up your motherboard.

Reg, Email is forthcoming.
