Athlon 950 What's the Blue covering on top of CPU?

How many forums did you post this in?

Yes, thank you.

funny this post should appear today, i just spoke to ( via e-mail) someone at AMD regarding this exact topic .
Here ill paste what he sent me.:

The 266 FSB parts are being manufactured and sold now. However, they may be
hard to find until they filter out into the retail channel. As for
different versions of the part? I would have to say that this is incorrect.

We do have 2 manufacturing facilities (Austin Tx, and Dresden Ger.). The
Dresden facility is equipped to manufacture processors using copper
interconnects. The interconnects are the things that internally connect the
transistors together. While the copper interconnects do offer better
conductivity than the aluminum, they do not change the performance of the
processor. Copper interconnects only allow us to hit higher speeds later
on. This will become more important on our 64 bit processors when we need
to hit very high speeds. In any case, there are not different versions of
the T-Bird and there are no price differences on our side. If resellers try
to market and price these parts different, I cannot say. But from our
perspective, a 1.2Ghz T-bird is a 1.2Ghz T-bird. The only difference will
be the FSB speed 200 vs. 266.
Hope this helps.

so i hope this clears thingz up a bit.
urban legends are a bitch!

Well from that email it'd lead me to believe that the Copper produced chips would be better for overclocking.

Just like Intels new Copper chips like the 700 that overclocks to 933 without a voltage change, and over a GHz with a small voltage boost. I think the AMD copper core CPUs overclock more than the other ones.
