I'm not really sure, that would depend on whether the palominos have the L12 bridges or not. If they do next thing is to compare between the Tbreds and pallies to see if the bridge configuration is any different
Sir Barton - one thing to note is that myself, and another member named Wardog50, both found that the L12 mod *doesn't work* at all (the chip is not detected as a 166 MHz FSB stock chip) when you do a pin mod - although it should. I only could get it to work by painting conductive paint between the pins, or blowing the actual L12 bridges. Good luck!
