Sorry it could not be worked out...

Anyways, for what it's worth- After checking my computer out with conflict catcher, if all looks well with the software I go a couple of steps more before giving up. I remove all of the PCI cards that i'm running and see if the computer will run right with just the new processor card installed. (And make sure all of the other PCI card drivers/extentions are off)

Reset with the cuda button, and grit my teeth.

I am interested to hear if the card checks out ok back at sonnet.... let us know?

if it runs good... then I re-install my pci cards one by one till the problem re-surfaces.

But, if running the processor card alone still crashes.. I pretty much have narrowed it down. it's one of 2 things:

The Card is bad,

or.....

My computer's bus speed may not handle the full 50mhz speed that the card is set for. (PM7500).

even from the factory, my 7500 was running less than 50mhz bus.

Dropping the bus speed to 47.9mhz usually solves this.

So much so, that i've been running a g3/333/1MB card OVERCLOCKED to 376mhz for over a year now with NO problems.

Honestly, The biggest pain was getting the ATI Radeon card to work. (The video digitizer was picky)

The upgrade cards are usually a great way to keep a good computer a lot longer.

P.S. I did strip the machine down to just the Sonnet card and experienced the same Finder Quit Freeze. I promise you I tried everything.

He Ricky...If you ever get the thing to go and are not afraid of Sonnet withdrawing warrenty support ( I dunno if they would?) check this out: http://www.sevencolo...w/cpu/cpu02.htm

Dude oc'ed his card by altering the system bus from 50 to 60Mhz...this allows the 16x Pll to hop it up beyond 800 (which is afunction of 50Mhz x 16(PLL) = 800Mhz) to 960MHz (16 x 60)!

I was wondering if this could be done given that the card sits in the PCI slot...how does the card "know" what the system clcok is? Karl what gives?

Too bad the sonnet cards don't have dip switches to adjust the bus speed... With finder freezes that always seems to be the problem. ( if I run the bus too fast.)

Really sorry for all the things I mentioned that you already tried. images/icons/frown.gif

Rikki,
Pretext: Our company has been selling Sonnet upgrades for over 2 years now, and I can tell you there is no "method to the madness" on some machines with CPU upgrades from any supplier.
We have seen it many times where a machine is perfectly stable with the standard processor but as soon as upgraded, very similar symptoms happen to what’s happening to you.
Our personal view is that some machines are just "worn out". They might have a small defect on the logic board, a worn joint here and there. The problems only become evident when the Mac is upgraded. As said before, this has happened many times to us , and I’m sure many other resellers.
Sorry, I couldn’t bring better news.!!!

Just one point about your ram. Make sure you machine hasn’t got any 4k refresh stuff in there. The interleaving problem is a symptom of this. Pull all your modules out and only install the same type eg EDO or FPM and ONLY 2k refresh.

Hope that helps.
Robert

The card sits in the CPU slot, not in a PCI slot.The cards have just the name "Crescendo PCI" because the first generation of high-end Powermacs with PCI slots (7200-9600) are usually just called "PCI Powermacs"
The machines's bus speed is given from the Processor card, not from the Mobo. For example, a 233mhz CPU in my Umax gave me a 46,6 mhz bus, my current 450mhz G3 45mhz, a G3 500 would give 50mhz. That's for cards with fixed bus ratio.

XLR8 cards and others are adjustable, so you can try to get more than 50mhz bus speed. In general, any PPC 7300-9600 should run fine with 50mhz, most can be OCed to around 55mhz, some to 60mhz without problems.

Sonnet cards and others without switches are only adjustable by soldering a new crystal oscillator on the card, that's really not recommended.

edit: The Sonnet Crescendo 7200 sits in a PCI slot. I'm not sure how this card works, but I think the bus speed is limited to the PCI slot's speed. But the 7200 in its original state only has a 30 or 40mhz bus.

heh thnx...what was I thinkin...oh... i wasn't. I had a 7200 once and must have soem how gotten the wires crossed in the excitement of finding another successful circumvention of Sonnet's alledged anti clocking stance...I'm not sure why I thought the upgrade goes in the PCI slot?! Must have been an early onset alzheimers moment. Sorry.

I've had my Sonnet 800 Mhz pCI Crescendo for about two weeks, since Sept 13th, and it has not been boring. I put it into a Daystar Genesis MP 800+ so I notice the speed most in apps that were not MP aware. I had PROBLEMS after the installation that turned out to be totally unrelated to the upgrade. Adobe Installers refused to install, and the video got extremely flakey. The problems were caused by a bad hard drive and a dying PRAM battery. I had been running OS 8.5.1 to maximise the nPower multiple processor card but I had no trouble installing the OS9.1 software upgrade to get AlteVec libraries. No trouble with the 5 volt 4k interleaved RAM, all twelve 128-Meg DIMMs. In fact, no trouble related to the card at all. i think that the price is really low compared to the $800.00 price mentioned when these things were first anounced.

Can xpostfacto be used in place of the sonnett pciX installer? I'm having no luck at all.
