| Power Macintosh 8500 Processor Upgrade? |
Posted by: blixanz on 2008-05-05 19:00:15
Received a 250MHz 604e processor a while back and have had no luck trying to get it to work with the 8500. 🙁
Or am i stuck with going for a faster 604 processor (currently 132 mhz) only or a G3 upgrade card?
Thanks

The 250Mhz part is for a different motherboard and should not work on an 8500. You need a 225 or slower part or a G3 upgrade.

Unknown_K is right. The 250MHz, 300MHz, and 350MHz 604e CPU cards require a different motherboard power voltage, and they have built-in "inline" L2 caches. Both of these features make them incompatible with the 8500 (and all other similar Macs, except the special 8600s and 9600s with the "Kansas" motherboards).
There are a few 233MHz 604e CPU cards out there (because Apple did produce a 9600/233) - but for anything faster than that, you'll need a G3 card in your 8500.
The good news is that even the slowest, and therefore cheapest, G3 card will make your 8500 faster than even a 233MHz 604e would.
Best,
Matt

The prices on low end G3 upgrades for PCI Macs have been dropping off a lot lately. You can probably pick up a 250 or 300 mhz G3 for almost nothing now and it will be faster than any 604.

Cheers, something to look around for 🙂

Are we sure about eh 604 CPU speed?
I have a 300MHz card and a 350MHz card that work just great in my 8500. They have been replaced of course by a G4, but are damned fast. I still have the cards buried somewhere. I was thinking of putting the 350 back in just for fun.

I want to upgrade my Power Macintosh 8500's processor as well. I have some great programs on it such as Photoshop, Word:Mac, Powerpoint:Mac, etc. but they run very slow on the 120 MHz processor. The OS 9.2 also takes a while to start up. So if you can upgrade the processor to a G3, does this mean I could install a 900 MHz G3? If so, that would be great. A 900 MHz G3 would run those applications, along with OS 9.2 very well. I appreciate any info, thanks.

^^better, you can get a 1Ghz G4. With the Alti Vec plugin photoshop will scream.

Can't beat it for $100, either.

I am surprised. Usually it is very difficult to find people still selling processor upgrades...
