Firmware confusion on G5 7,3

So, I'm looking at this G5 (Powermac7,3) 2x2.0 GHz and the system profiler reports Boot ROM version 5.2.4f1. According to Mac Tracker, the most recent firmware update is 5.1.8f7. Does that particular update install firmware version 5.2.4f1? Is the confusion due to an odd discrepancy between the updater version and the actual firmware version it installs?

Also, does anyone know what firmware this G5 shipped with originally?

27" iMac i5, 2GHz Macbook C2D, Mac OS X (10.6.3)

Hi, unfortunately there are 2 G5 2*2GHz PowerMac7,3s...

Regardless, I think you have the latest Firmware for your Mac, certainly later than 5.1.8f7

That update was only for the Power Mac 1.8 GHz, (600 MHz bus), single-processor Power Mac G5 (Late 2004) model as far as I can tell...

But is a different size than... ???

My thanks to you both for your quick and helpful replies.

Hatter, I don't really know the history of this G5, but I suspect that it was a BTO purchased through the Apple Store, as it has a 400GB Apple-branded hard drive.

BD, this G5's lack of a modem makes me think this is the second of the 7,3 models you linked to. Also, it has a 128MB ATI video card installed, although perhaps this was an option on the earlier model which shipped with an NVIDIA card by default.

Again, thanks to both of you for helping me unravel this mystery. I'll probably end up posting separately about the problems this G5 is having, which at one point I suspected might be firmware-related, but now I'm not so sure.

I also doubt a Firmware problem FWIW. 🙂

Finally got them both Downloaded, ineed...

Would be a downgrade, (if possible), to Version 5.1.8f7

The oter one I'm not positive as to what version it is... but you don't need it!

What exactly are the problems you're experiencing?

Very good idea! 🙂

Yeah I doubt it's firmware, especially now that I know this isn't a June 2004 G5... confirmed by a "©2005" stamp on the logic board. Thanks for enlightening me to the existence of another 7,3!

Not sure when I'll get to making a new post, as I'll do some more troubleshooting first, so here's the short of it: it's crashing a lot, seemingly randomly. Sometimes it's an infinitely spinning beach-ball, other times multilingual screen of death, other times just freezing up. It's even crashed on the first boot right after a clean install of 10.5.4 on a new hard drive.

However it passes every test I've put it through, including multiple runs of AHT. The memory is all Apple-original and has passed AHT, as well as Memtest booted into single user mode. No peripherals or PCI cards. Sometimes it won't crash for days and other times it won't boot at all.

The hard drives are properly jumped to run in 1.5GB mode and I'm running low on ideas, other than the possibility that this is a problem with one of the procs or the logic board. See... now I've gone and written more than I should, but I suppose I'm just hijacking my own thread! 🙂
