keeshond Posted June 7, 2007 Share Posted June 7, 2007 Hi, I want to know whick PowerPC I have. These are my specs from "About this Mac": Computername: Power Mac G3 (PCI-video) Computermodel: PowerMac1,2 Processortype: PowerPC G4 (2.6) Number of processors: 1 Processorspeed: 350Mhz L2-cache: 1Mb Memory: 384Mb Busspeed: 100Mhz Bootromversion: 1.1.2f2 If you want to know anything else, please let me know. The reason I want to know this, is because I've placed 4 banks of 128mb memory. In bank 1 and 2 the 128mb is recognized, but in bank 3 and 4 only 64mb is recognized. How is this possible? What's the maximum amount of memory I can feed this Mac? Does anyone know if there's an EFI-update for this Mac? Thank you for any response.

Danyel Posted June 7, 2007 Share Posted June 7, 2007 Hi Keeshond: It appears that you have PowerPC G4 Processor. If I am not mistaken, EFI is new architecture available on Mac's with Intel Chips only. PowerPC's use Open Firmware. http://appleintelfaq.com/#17 http://en.wikipedia.org/wiki/Apple-Intel_a...mware_Interface --danyel Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-379569 Share on other sites More sharing options...
consolation Posted June 8, 2007 Share Posted June 8, 2007 It looks like a G4 Yikes! series. Yes, it will use open firmware. is it one of these by any chance: http://lowendmac.com/ppc/g4.shtml Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-379835 Share on other sites More sharing options...
A Nonny Moose Posted June 10, 2007 Share Posted June 10, 2007 You have a Yikes! Get Mactracker, btw to answer these very questions. It's a wonderful piece of software and it even has a Windows and iPod version.

keeshond Posted June 11, 2007 Author Share Posted June 11, 2007 Thank you all for your response. It looks like the Yikes! But that doesn't explain the memory issue, because according to this site, http://lowendmac.com/ppc/g4.shtml, it is should be upgradeble to 1gb. Could there be any chance that I have to upgrade the Open Firmware? Or isn't this upgradeble?

A Nonny Moose Posted June 11, 2007 Share Posted June 11, 2007 The memory thing just tells you how much it can detect if I remember correctly Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-382647 Share on other sites More sharing options...
keeshond Posted June 12, 2007 Author Share Posted June 12, 2007 I've inserted two PC133 128mb DIMM's. Could it that it can't handle PC133 memory? Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-383016 Share on other sites More sharing options...
ebsen Posted July 14, 2007 Share Posted July 14, 2007 you have to use the correct ram modules. yes it reads pc133 but there are other specs the ram has to live up to. read about it on apples website. it should be the right amount of chips on the stick and comply to the jedec guidelines and other things. also it must be non ecc unregistered and so on Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-407879 Share on other sites More sharing options...
mayhew2345 Posted July 14, 2007 Share Posted July 14, 2007 it will also except pc100 from a old pc as well as 133 looks like the module is just not correct if u are running tiger it will max out at 1.5 gigs of ram not 1 Link to comment https://www.insanelymac.com/forum/topic/53247-whick-powerpc-do-i-have/#findComment-408096 Share on other sites More sharing options...
