It is a G3 500Mhz. It doesn't work in my 8600, is it possible there isn't enough power for it or would Apple had made sure it worked only on the clones?

If I can get it to work I have a nice G3 on my hands. Got it for ten bucks. ;-)

Those are markings I can find on the CPU Card.

Now, the original 200Mhz 604e CPU in my system has these markings:

Compared to the original 604e Chip markings:

IBM Q51012KCPQ (TOP)

XPPC604EBC200BE (BOTTOM)

So, the one I have def is not a 604e.

You prpbably have a last of the line 604e 350 that originally came from the last 9600 PCI macs before the G3 desktops came out.

Apple processor cards that have a 250MHz, 300MHz or 350MHz 604e on them -- the last 604e cards Apple ever made -- will not work at all in any computer except for an 8600/250, 8600/300, 9600/300 or 9600/350. These are the four models in which Apple originally shipped those cards. Apple never offered those cards as upgrade cards. They were only offered as original equipment.

Those particular Macs used a modified motherboard that provided the correct voltage in the processor slot to supply the 604e 250, 300 and 350 CPU cards. The motherboards were specially modified Kansas motherboards, and the CPUs were known as special "Mach 5" 604e's. They also had inline cache, which had its own dedicated bus to communicate with the CPU at 100MHz. This was a faster and more direct setup for cache than the motherboard-based L2 cache built in to previous Power Macs. It was a slightly less direct and slower setup for cache than the backside cache that would soon be built in to the G3 systems. This inline cache setup is the other reason, besides the different voltage, that the "Mach 5" 604e cards won't work with earlier Power Macs -- the L2 caches will conflict with each other.

So unless The Balance of Judgement's 8600 started life as a 250MHz or 300MHz model, the CPU upgrade he bought won't work in it, or any other Mac (except the aforementioned 8600/250, 8600/300, 9600/300 and 9600/350). In fact, it's possible that the motherboard has damaged the 604e card -- IIRC the mobo supplies 5v to the processor slot, but the Mach 5 card wants only 3.5v.

- "Mystic" Color Classic, full '040, 36/700/enet, OS 8.1

when I fed 18v to my 6v tape recorder, it started smoking...

if processors could do something similar, you better just take your 8600 back to whatever it was, and be VERY happy that you have such a WONDERFUL computer at all....

Anyways, back to pick another CPU.

:/

So the moral is, don't pay the extra for an 8600 or 9600 running over 233MHz if you're buying one second hand, as soon as you upgrade the CPU the Mach 5 machines would be slower than the machines that were originally slower, if that makes sense!

I suspect the card works as well as it did when you got it, I wouldn't worry about having it plugged in for a few seconds.

and I once read this "pick your own adventuer book" where they had robot kids, and this evil guy took themto "camp" and send thim into this pool of UBER acidic water to harvest some gold or something for him...

naturally, the story line of that "pick your own adventure" book changed alot

but yeah... Iv'e also heard about that bus issue...

I bet those systems aren't that bad with thier intended 300 and/or 350MHz processors though...

It IS a G3 Card. Just a very special one. Won't work in Apple Branded Systems. Only Power Tower & Power Tower Pro Clones.

Also I found this http://www.simdtech.org/apps/group_public/email/altivec/msg03538.html which has the quote that unknown had in his post.

From those marking I would say that it is a 604ev at 350MHz

B-G3500

B means Cerarmic Ball Grid Array (CBGA) packaging Which would make seince as all CPU card I have seen use BGA packageing.
- is just a place holder all part numbers have this
G means that the chip runs at 2.0 to 2.1 volts
350 Means the chip runs at 350MHz
0 has something to plant that it was manufactured at.

I just sent IBM an email to see if they have any info.

I'll go grab next month a Sonnet Card or something for my G3 needs.

This is what he said

Check with your disti. This is not even close to a good part number - probably a 750L, dd2.2 or before, 350MHz at 2.0v min/105C max, but that is not at all certain
