I recently picked up a used 350 Mhz Sawtooth for $55 and I also got a 400 Mhz Sawtooth CPU for $7. I can just swap the 400 Mhz CPU with the 350 right? I'm assuming I wouldnt have to change any jumpers??? Thanks

Thanks! Replaced the cpu in about 5 minutes and it's up and running. It's kinda funny, this powermac isn't terribly slower than my iBook.

Two factors attibute to that. One of them being that the G4 processor used in the early G4 Macs, dubbed the 7400-series, is a good bit faster at the same clock rate than the G4 processor used in later Macs, such as your iBook, dubbed the 7450-series. Second to that is the fact that the early iBook G4s were serverely cache cripped, with only 256k of L2.

BTW; You might want to take a run at finding out of your Sawtooth is dual-capable. You can find Dual 500MHz modules on eBay for as little as $60 now, and you would find the speed boost to be quite phenominal. Your Sawtooth would blow your iBook out of the water.

Uni-N Revision Checker

I have a Uni-N Revision 3. I'm selling off some old hard drives and other sundry equipment for a cpu upgrade. I'm looking at either a Sonnet 1.3 or 1.4 Ghz G4 with 2 MB L3 cache.

Not a bad idear. But I'd look at PowerLogix and Giga Designs over Sonnet. They each charge less than Sonnet and allow you to tinker with the clock speed of the upgrade without voiding the warranty. And PowerLogix seems to have resolved their quality control issues recently so I'd say quality is comparable across all three of the brands.

hello
any of these brands, PowerLogix, Giga Designs or Sonnet, will work fine in my Digital Audio? I ran the uni test and it gave me number 11 and am only interested in removing a dual chip and installing another. Is any one of them of better quality, easier to install or have a better cost benefit? Personally, 1.3 dual would be great for me, especially since it wouldn't cost all of 5 or 6 hundred.

I saw the test numbers for Lateralus's tower in the photoshop blur forum and it smoked. thas was for dual 1.8, correct?

from the sonnet page about there 1.3 duet upgrade :
Dual G4 745X CPUs running at 1.267 or 1.3 GHz

On ebay :
http://cgi.ebay.com/Gigadesigns-Dual...QQcmdZViewItem
these seem to be the same chips?

Perhaps somebody can give me layman's version of the G4 chip upgrades possible?
Are there many different 745? series chips?

all the best and thanks again.
