With a few exceptions, the K7 family has been multiplier locks since the chips inception. On the slotA original version, the multiplier could be unlocked via "Golden Finger" devices attached to the daughterboard slot A pcb. The thunderbird mounted on a ceramic bed (top left in this picture: watch.impress.co.jp ) can be unlocked by closing L1 bridges with a conductive material (number 2 pencil is very popular) The new package is plastic, not ceramic and it remains to be seen if the L1 bridges can be closed as easily with the pencil trick. Here's the followup from milo's link: "Well, I tied the pencil trick -- it was a no go. Backed down the fsb to 133 and tried booting at 12x and it came up as 11.5x -- so I figured it was still locked. Oddly, then I backed the Multiplier down to 11 (underclock) the CPU would not post. Wierd. It just hung at "FF" on the postman. I actually panicked a bit because I thought I killed my board. When I set the dip switch to auto detect -- it booted right up. On the chip itself -- it seems like where bridges have been severed there is a little microscopic valley all the way down the line. In other words, whereas the old Athlons just has a laser cut that severed the connections, it seems more like something has actually etched away the connections. I hope that makes sense. What I thought were raised bridges is in fact just the opposite. Everywhere the bridges are cut, their is a tiny, even and symetrical gouge or valley betwen the copper dots. I hope that makes sense. I think a conductive pen or some other actual connection will be required. BTW, another oddity. The row of L1's is made up of five pairs, not four like on my old Athlon. Any other ideas? " Meanwhile, increasing FSB/memory speed remains a viable choice so long as the rest of your infrastructure supports it. (currently running an old 66 mhz celeron 600 at 900mhz by pushing the FSB on my ASUS P2B up to 100 mhz. It will be interesting to see what material emerges as the bridge connector of choice for the XP chips. dave
