I wonder if the number XC68040RC25B states that it is supposed to run at 25Mhz or if the 25 in the number on the CPU is just a coinsidence? regards Peter _ Skaffa fler messengerkontakter - Vinn 10.000 i resecheckar! http://messenger.msn.se/promo -- Quadlist is sponsored by http://lowendmac.com/ and...

The way I understand processor fabbing to go, a chip maker makes up a batch of chips, then runs them through various tests. The ones that work at lower speeds get rated lower, the ones that stay in spec at higher speeds get marked higher. This means that a chip marked for a lower speed might well run fine for general use at higher speeds, and is the basis for the entire overclocking bit. That said, if you're going to run a 25mhz part at 40, you definitely want at least a heat sync, and maybe even a fan. Scott Holder -- Quadlist is sponsored by http://lowendmac.com/ and...

I have a heath sink from the donor machine a Quadra 700 i believe. But no extra fan. So what happens if it gets to warm? Does it hang the machine or what are the signs? It runs now at 33Mhz and there is no problems as far as I can see.

Re: Overclocking
OK, I have 3 '040 machines that I'm considering upgrading to full '040 instead of LC processors. First off I have an LC630 with a 33MHz chip in, and I've tracked down a full 33MHz processor to drop in as a straight replacement. I've also got a couple of Performa 475s, and unfortunately I have only seen other 33MHz chips (none purchased yet). Would I be right in assuming that if I drop in one of these, I'd have to go through the overclocking procedure for the motherboard. Seems to make logical sense to me, but just in case I thought I'd ask :-) I'm not to sure about over clocking the 475 really, but that's yet to be decided. No, the 33 MHz chips will work fine at the original 25 MHz of the '475. Overclocking the 475 isn't too difficult though. See http://homepage.mac.com/schrier/q605.html for a description.

No. That's a bit of marketing bullshxt that Apple's ad agency came up with. Nevertheless, where can I find instructions on how to overclock this model specifically?
