I'm looking to get a processor upgrade for my 450 Sawtooth. OWC [eshop.macsales.com] has a wide selection and I was wondering if anyone has any recomendations.

Are the PowerLogix cards any more reliable than in the past? Will I get the benefit of the 1.6ghz or is the 100mhz bus going to be limiting me? Will the L3 cache make a difference in this machine?

Thanks!

I put a OWC Mercury Elite 1.3/1.33 processor in my 400 sawtooth yesterday. It is screAming along at 1.4 Ghz as we speak. Nothing but praise for this one, although it is a replacement. The first one shipped was DOA, but OWC cross shipped a replacement that is working great. Guitar Rig went from 100% cpu usage to 20%.

I've owned both an older Powerlogix G4 upgrade card as well as a newer OWC Mercury Extreme G4 upgrade card.

The Powerlogix card ticked me off because I lost the ability to put the computer to sleep and swore that I would never buy another Powerlogix product because they never dealt with that problem.

The OWC card had better compatibility out of the box. Sleep function worked fine.

The Powerlogix card is still running fine (albeit, no sleep function) after almost 4 years.

Powerlogix is now wholly an OWC brand. The prior owners of Powerlogix/962 no longer have any involvement with the company. The QC of our PL products is top notch, like so with all our products. The current products sleep correctly and have our full support.

The 7455 upgrades benefit from the 2MB L3 cache. This makes a beneficial diffence with any heavy processing.

The 7447s have a higher clock speed and larger L2 on chip cache of 512K (7455 has 256K L2) but no L3. The higher clock balances somewhat for the lack of L3 in the heavier processor functions, but - the 7455 w/2mb L3 is advantageous still. However - for web browsing, ms office, stuff that isn't continuous processing of a file, etc - the higher clock speed of the 7447 provides more 'instant' gratification higher performance.

i like Sonnet.

I just got a mercury extreme 1.2 from OWC. I can hear the fans running, never falling asleep, from 30 feet away in an other room, and it's in an armoire! The old sawtooth would put itself to sleep after inactivity, and you couldn't hear a thing. I guess the two HUGE fans on the top never shut down, even sleeping. Not sure if this is how it is supposed to be, or if there is some setting that OWC didn't tell me about. Larry??? Is this the way it is? Even selecting sleep does not make it quiet...

OWC Larry, you need to heavily market that Powerlogix is now a wholly-owned OWC brand and has nothing to do with the old Powerlogix. So many Mac users in many forums have nothing but disdain for Powerlogix.

Honestly - it won't be the Powerlogix brand that we market. Learned enough to know that is an up hill battle regardless in the US. Internationally, it's better - but nonetheless - other plans.

Regardless - the Powerlogix branded products we are now selling have our full and unwavering support.

Bradsdad:

The current model processors we are selling DO turn all fans off when the machine goes to sleep. Deep sleep, that is; regular sleep (if you have just the monitor turning off) won't shut any of the internal fans off.

Try this; manually tell the machine to sleep. Do all of the fans turn off, the drives spin down, etc.? If not, then you have a PCI card installed that does not support deep sleep and that is why the fans are all staying on.

Unless that furniture is open back, you are simply recirculating warm air, and that will
cause your thermals to be active always.

This is analogous (sort of) to Harrier's sucking in super-heated air - they can't compress it
like they can cool air.

The new Lockheed design with the drive shaft fan blows cool air to the ground, and eliminates that aspect of getting lift.

So, the cure here is to either chop up your furniture or add a new F-35 JSF to the system for better cooling. Might be similarly noisy, much much improved airflow.

Which 7000 series processor is it that we're stilling waiting for to show up?

Larry, That 1.6 dual for my Cube looks tempting, I haven't looked at them lately.

Jamie,

Before upgrade, the system would (deep) sleep no problem. Now, I even tried to select "sleep" but just the display went dark, with all power still going strong, fans ablazing. I do have
a POS Keyspan USB 2.0 card that is in there. I would think the Adaptec UltraSCSI card would be fine. And the PCI Belkin wireless 56K fills the slots.

Go Bulls tonite!!

Hi-
Pull all the PCI cards, try them one at a time. I'm betting the SCSI card is it. One of them is the culprit....
