G4 PowerMacs - upgrade the processor?

Anyone done this?

I'm about to inherit a G4 with Logic 4.8.1 -

I'm not certain what speed the machine is, but was wondering if I ccould buy a faster processor and directly replace the previous one?

My daydream is, if it is a sub 1GHZ processor, I could replace it with a faster processor, and have a happy life with a more stable Logic that doesn't run out of steam.

Anyone know if the pin configuration has changed in the various processors over the lifespan of G4 motherboards with PCI graphics slots?

there's a place in the states called "Other World Computing"

that's where i got my processor upgrade..

i got their brand instead of a sonnet..

easy as hell to install and it works quite nice, but i'm sure someone will chime in and say that the system bus will be the bottleneck..

but **** it..

Thanks for the info!

What did you upgrade from >>> to?

And what machine is it? Quicksilver or later?

Yeah I'm sure someone will chime in re the system bus, but Logic mostly shows the processor at 100% when it crashes on my old machine.

Sometimes it is Disk I/O with large track counts

ahh..forgot that link,

here it is..

OWC Processors

i upgraded from a G4 Digital Audio 533Mhz..
i'm not sure where that fits in with the QuickSilver models..i think it predates them.

I had an old G4/450 that I had upgraded the processor on. I picked up a Gigadesigns single processor 1.4Ghz (which actually went up to 1.7)... think they go much higher now qand even have dual processor versions. http://www.gigadesigns.com/

Worked flawlessly for me for the 2 years I used it... then sold it when I got my G5.

Be sure that you machine is in fact upgradeable and that the processor upgrade is compatible before you buy... I think there were a couple early G4 models that weren't.

I've got the gigadesigns upgrade in mine too, I went from a quicksilver 867 mhz to a dual 1.6 processor, it was incredibly easy to do, and was only like $300-400. it performs leaps and bounds better than the old processor, I'm running ptle with lots of altiverbs and the like...

well worth it imho!

Do not invest any money in this machine. It's too old. First, the processor, then a hard drive, then the power supply, extra RAM, new PRAM battery. Oh crap, the MOBO failed, and I just spent all this money. It is absolutely not worth it. You may get years of use, but it is just as likely that you wont. A decent brand new PC can be had for $400 THAT IS MANY TIMES MORE POWERFUL. Even a refurb Mac Mini from the Apple Store can be had under $500, and this is a core duo 2 machine.

Dropped a Gigadesigns G4 dual 1.8 gHz into a G4 dual 533 gHz about a year and a half ago with no problems at all... got me passed having to buy a G5. I'll buy a new intel Mac in the next few months, but will keep this one around as it's still a very stable and respectable machine.

Thanks guys... How much did that set you back?

And what's a kernel panic?

--

harry_seldon: good points. Seems the Apple components are way overpriced (power supply for £90 in the UK for 334 Watt --- actually that spec seems a bit low)

Its always a punt I guess, but this machine hasn't been abused, so I would be very unlucky to see a catastrophic failure

I'm running 10.4.10 now, with zero problems on upgrades to this point. Are you using any extra video or audio cards in the machine? Gigadesigns processor upgrades can sometimes be a little sensitive to heavy drain on the computer's power supply. Kernel panic's can be a symptom. There are dip-switches on the processor card that can be set to compensate. If you do have extra stuff plugged-in, call Gigadesigns and tell them what you've got and they'll give you the settings.

If that's not the case, try re-installing the last upgrade from a full "combo-updater" that's been downloaded from Apple's support pages and not from the "software update" control panel. That usually clears-up any update problems. Oh, and it's a good idea to "fix permissions" before and after the update.

for Blast9:
kernel panic = system crash... a freeze usually accompanied by a message to restart the computer.
The cost was about $480 when I installed it. They currently make a dual 1.6 now with a price of $399.

A full-on system meltdown due to incompatible/problematic driver software. Requires a hard re-boot.

I'm with harry-seldon (except for the $400 PC bit...). Don't throw money into this box. Stick it in a closet and use it for a file server or something.

agree
check the articles in Sound on Sound (.com)
they featured some of these cards.
some did have incompatibillity problems



this is a mild kernel panic (grey screen)
also the machine could go completely dead
that (in case of the G4) requires a manual reboot from the board itself
scary stuff LOL
