there are a number of processor upgrades on the market. I understand that pci type accelerators are ill advised for audio processing, but what about the ones where you swap it for your old processor. does anyone on the forum have any experience of using say sonnet st g4 upgrades? this is going tto be the only way to improve my digioo1 system on powermac g4agp400 on my budget with a mortgage to pay and a baby due in may.

thank you

Your right the PCIs are crap. They will use up your processer and then switch over to the other. A very PC way of daul processing. Sonnet makes good products> Check the bus speed on your G4 and make sure it can handle the upgrade you want. If the bus is slow enough the upgrade want do much. I think you can get way with a 1 ghz upgrade.

check xlr8yourmac for the tests, users advice/experience, it's unvaluable. Read the users comments. the place is sometimes a bit strange to navigate, but it's full of input.

Be very careful that the bus speed is not lower with the upgrade as it happens regularly.

thanks for all of your help!

I installed the 1 Ghz Sonnet in my 450 Mhz AGP graphics G4. I couldn't install a dual processor ugrade because the ASIC was too old.

It was quite easy to install and has been running for a year. I've also put in 1 gig of RAM, two 120 gig hard drives and a Radeon 8500 video card. According to comparisons done with Xbench, it is now the equivalent of a dual 836 Quicksilver and compares favorably with some of the single processor MDD models.

you could ask on the digi user conference to see if anyone has had a similar upgrade done, www.digidesign.com, press support then press user conference, I understand there were a lucky few who had g4 upgrades working ok in their 9600's with tdm pci systems, I had a sonnet g3 upgrade in my 8100 with the old nubus digi tdm system and that was fine but that's irrelevent the underlying message is that cpu upgrades are widely used and generally reliable.
