Full 68060's 75Mhz for sale

[Rob]

Freescale do not list full 68060 75Mhz on their site, the fastest listed is 60Mhz which I have on my Blizzard.

If you install the CPU on your card you can you the CPU command or Sysinfo to check if everything is present and correct.

My Blizzard currently is clocked at 66Mhz.  I clocked it up to 80Mhz, but it would hang as soon as you switched the FPU on (i.e. running setpatch).  Using the CLI, I was able to run a few demos that didn't require setpatch to be enabled and I was very impressed with the speed.

There are FPU versions of quite a few applications out there and a few that require one to run, I think Quake does.

If these turn out to be full 68060 75Mhz parts and they can run stable at 80Mhz I might be tempted to part with $60 for one.

On the Mk-II series I believe, they screw/corrupt the scsi. But of your not using a scsi it will work.

It can be a bit of lottery with over clocked Blizzard 1260 and SCSI modules, some work at higher speed and others don't.

Freescale (formally motorola) dont make and have never made FULL 060's at 75MHz

Where are the photographs of such chips? (In focus so I can read the numbers on the chip).

The MC68060RC50 with mask E41J has been known to overclock to 100MHz (No Amiga Accelerator can run that fast).

The very last version of CSPPC as been known to run at 75MHz with jumper changes and firmware settings and an extra crystal.

Apollo 1260 is also known to run at 75MHz with these chips, but the memory controller design means that it doesnt run much faster in real terms.

I will when i get the a4000 and cppc back.

[zyphoid]

who has schematic, pics/diagrams directions of such a task. i'm sure us novices don't want to screw up or boards,   i mean with swapping chips, and installing crystals and all.. it's tempting to put out a few bucks to increase amiga performance

just how do you clock up anyway?

[mike-]

its not a clock up... i wouldnt recommend doing that anyway.. But replacing the crystals, with say, 80 or 100 mhz ones, more voltage probably, and keep the temp down, big heatsink with a good fan on for instance.

Where's this piccy from?
Something doesn't seem right about the mask number (the only matches I can find for '00E31F' come up as 68040's), where's AlexH when you need him?

[mike-]

just searched on google images. I have on sitting on the table...  They exist...

[murple]

I think you've got a bright future in importing merchandise from parallel universes. Can you get me an Amiga 6000?

I dont know what you have, but the manufacturer site says that full 060/75's do not exist.

But just cos it says 'MC68060RC75' on the top doesn't mean that's what's in the silicon  :-(
Only last year someone got ripped off buying a batch of relabelled '060s(link)

Rough translation from the CT blog..
"Apparently there are 060s with falsified inscriptions. They have a white print  instead of engraved MC68060RC50. You can also recognize it by the number on the left side (e.g. S23328-002 instead of -004). "

I got some pictures. but they are taken with a cell phone... so i wont even bother loading them up.. i couldnt make out the model no. myself even...

This one here says: MC68060RC75 01G65V MALAYSIA
THIS IS IN REALITY A XC68060RC50A!

I'll hunt for a proper camera.. I've got the friggin flue so not much is happening. Not even for http://amigaweb.net

Hmm. i'll wait until i get the cppc back and test with that  then

[mike-]

ah the left hand side. barley visible is 523326 002. but t hats in gold or what ever

Just google a bit - all 68060 01G65V I could find are (RC)50 MHz...
