More Power!!!!!!!

For the time being i don't need an 060 and i'll just try boosting the 040 and if i decide to upgrade to an 060 the new crystal i'll be putting in will mean that i can run the 060 at 66.67 mhz for a small turbo boost if i ever decide to get one.

@Buleste

sounds like a plan m8y.

the 040@40 will push about 35Mips, where as an 060@50,hz will push closer to 80Mips.

if you get a latent revision mask of the MC68060 these will clock to 100MHz... thats.... thats a shit load of Mips.

one of the problems you may / are likely to encounter with over clocking the 040, is the memory access speed, you will need to change / make sure that you are using the good 60ns or better memory. you may need to add another clock / oscilator for independent memory speed.

I'll be following all the instructions from here so i should be allright so long as my soldering hand stays steady and true.

I've just been reading more on the overclocking of the PPC and my board is a 210 as it has a 60 Mhz crystal running at 3.5x not the standard 66.67Mhz running at 3.0x yet it's never been overclocked. How strange. Still thats Phase 5/DCE for you. Never let a standard get in the way of a build.

Just replaced the crystal for my 040 it's gone from 18.95 Mips to 25 Mips and running smoothly. Now I've done that i'll look into Overclocking my PPC. Shame I can't get a 40 Mhz crystal though.

It's Alive!!!!!! Today i completed the upgrade by adding a 66.667 Mhz crystal to my PPC so that it now runs at 233 Mhz and everything works fine. The best thing is as i've installed them via 8-DIN sockets should i ever find a 80Mhz crystal i'll be able to up the speed again or if things start getting a little toasty i can downgrade until i get a new heatsink and fan for the PPC. Shiny!!

AmigaKit have an 80 Mhz crystal in stock. That'll boost my PPC to 280Mhz which is about as fast as a 603 can go and as I'm using the sockets it's easy to install a new crystal. In the words of a Mister F. Mercury and a Mister B. Blessed "Who wants to live forever?"
