Hi,

I'm looking for a Powermac G5 quad (A1117/A1177).
Who has one for sale?

Thanks
J

You might wanna add a location.

Around here there is pretty much always at least one for at <100€.

But even within Germany shipping is 25€ or more, so....

Hi Kronos,

I'm living in Belgium.
I can imagine shipping cost will be high due to the weight.
Which German sales websites do I need to look at?

ebay, kleinanzeigen.de

Always something, sometimes something good, often something good to far away ....
I myself am looking for a 2.3PCIe/DualCore, no need to learn plumbing.

But still with a bit a of patient and the will to pick something up you will find.

Thank you for the info.
I will start monitoring kleinanzeigen.de.
Ebay has some G5 quads but they are overpriced.

Regards
J

Just a small suggestion.

If you are going to be using it for MorphOS. The single processor PCIe 2.0 and 2.3 are a better solution imho.

They run much cooler and use the massive heatsink and MorphOS only sees one processor so the other one is useless. The QUAD MB's tend to fail as well.

You can swap out the 2.0/2.3 with a 2.5 processor and you will be good to go, exactly the same for MorphOS as the QUAD.

There are a few videos out there describing and showing the process. I know Chris Edwards just did it as well and made a video for it, no idea when it will be released.

Good luck!

Hi matt3,

Thanks for the additional info.
What does "MB" mean?

MB = Motherboard.

For some reason the QUAD systems have a decent amount of motherboard failures. Good opportunity to purchase the processors as they usually are fine. That is exactly what I did and many others who bought a 2.5 from a failed motherboard system and used the processor to put in a single processor variant.

The single processor PCIe system are very well made and run cool and quiet. No other PowerMac system for MorphOS is as good.

Good luck!

He makes only 1 mistake, claiming that there was a 2.7GHz model suited for this hack as 2.7GHz was only on option with AGP G5s.

That one (#6)?

@Andreas_Wolf
@Kronos

No he got a 2.5Ghz processor, so he has to pull a cpu off the heatsink and mount the 2.5. He made the video a week or so ago but no idea what his queue looks like to say when it will be released. He may bundle a 3.19 review as well with it, not sure.

@Kronos

Yeah, I told him the 2.7 is a different type of cpu and wouldn't work, even if he figured out the power connector differences I doubt the motherboard would work with it.

From my experience the 2.7 PCIX is the best for playing media and with wayfarer.

The 2.5 has a faster cache I think and faster memory maybe.

So for most things the 2.5 on a PCIe is maybe a bit quicker or very similar, for the few things that hit the cpu hard the 200MHz difference makes a difference.

I never could tame the 2.7 PCIX to be a quiet system, the 2.5 PCIe is sooo much quieter...

What I find interesting is that the CPU clock seems to force the mobo FSB and not the other way round.

Well ran out of patience and spend a whole 40€ and 1€ in gas money on a 2GHz version.

Everything ready, Radeon : check SSD : check 3.19 BootCD : check
..

Power cable : fail

Had no idea that I would need a 16A rated one with horizontal pins.

Well that is on order, also found a DP+HDMI card with no extra power that does support overlay (the one I already have is a bit too high up the food chain).
Won't be able to test anything till next weekend ;(

But, quick question what kind of RealTek NIC do I need?
Quick search on ebay gave me some RTL8125B (2.5GBit) a 8337XTR (1GBit) RTL8111 (1GBit)
There is also a RTL8153 (1GB) based combo card with USB3 based on NEC chip which might yield some extra USB2 ports with an optimistic future upgrade to USB3.

I have both pcie the 2,3 and the 2,5quad. And i also have the 2,7 AGP not working anymore.
Is it possible to swap the cpu from the 2,3 into the 2,5? So i could spare me to buy a new MorphOS license.
The 2,5quad is loud like a F14 Jet.

A lot of things are possible, but it seems that Mr Edwards is trying to do it the other way round giving him an air cooled single (DualCore) CPU 2.5GHz G5.

The other way round you would end up with 1 air cooled DualCore CPU in a motherboard designed for 2 DualCore CPUs which will either:
- work just fine (you never know till you try)
- a non booting system
- a system so confused that it will run the fans at 100% all the time


If you fancy some experimenting I would start by simple removing 1 CPU in the Quad. Preferably the one in the socket unpopulated on 2.0 and 2.3 models (I think that would be the top one). If that works mount the 2.3's aircooler to the remaining CPU.

This is assuming that you have a license for the Quad.

If you succeed I'll raise my hand showing interest in that 2nd 2.5GHz CPU ;)

Swapping a dual core 2.5GHz processor into a single processor motherboard using the heatsink works perfectly well as a bunch of us have done so.

cpu swap

Since the cpu module tells the motherboard the clock speed to run at, putting a slower processer in should work as well.

I had a dead 2.3 in my dual cpu pcix system and morphos worked fine. There may have been a command to turn it off as well. So your chances should be decent.

Good luck!

Stupid ideas that work are still stupid:

Don't try this at home...

Well it does see both the MorphOS CD and the SSD I had prepared on the AGP G5, it does boot them, but no display an any port of the R5 230. Actually not 100% sure if the SSD booted, but it did show up in the startup menu.

Hope the HD4670 will fare better.


@matt3

Good to know it would work that way if I get a 2.5GHz CPU, but what ThePlayer suggest is using 1 CPU in a dual socket Quad mainboard which might a different set of dice.

Up to installing 10.5 to make sure those SATA ports work for sure.

> what kind of RealTek NIC do I need? Quick search on ebay gave me [...] RTL8111

That one should work (#41). Don't know about the others.

> I had a dead 2.3 in my dual cpu pcix system and morphos worked fine.
> There may have been a command to turn it off as well.

The 2nd CPU is allegedly (#35) turned off automatically by MorphOS since 3.10.

@ Kronos - Just for info - the Airport Extreme A1027 works in the PCIe versions of Power Mac G5s (A1117/A1177 models).

I have this installed in my PowerMac DC 2.0 GHz system, though I haven't got the system running, but it is recognised in Mac OSX Leopard, just be careful which way you orient the card. I seem to remember it needs to be with the "Airport Extreme" wording facing upwards. There is no metal "keyed" slot to enforce correct alignment over the Airport/WiFi connector, as there is in the earlier PCI Power Mac G5 models, that is why you have to be sure you have it oriented correctly.

Most users try to find the "RUNWAY" card, which also plugs into that slot, but also allows (I believe) you to mount the Apple Bluetooth hardware on it as well as the Airport Extreme card (A1027), but as the "RUNWAY" card is as rare as "hens teeth" and sells for "silly" money I haven't bothered trying to acquire one, as I don't need it.

Also, if you want to use some Bluetooth keyboard (Apple A1016) or other Bluetooth hardware then if you have a dual-boot system then most of the mini-Bluetooth dongles available via internet online sales will give you Bluetooth capability if plugged into a USB socket on the PowerMac. Ideally they need to be compatible with Windows XP as those are the ones I have found to function correctly on Mac OSX Tiger/Leopard.

Hope this info is useful.

It's also worth noting that when placed incorrectly, the Airport Extreme card will stop your G5 from booting at all. So if you've just mounted A1027 and the machine won't even start (no reaction to power button) - you know where to look.

(this statement has been personally verified on no less than two Power Mac G5's to the unspeakable personal horror and then - relief of the one writing these words).

Well I did get 10.5 installed so SATA does work (it was sold as non booting with a HDD installed).
Only saw 512MB which I fixed by swapping places for the Apple 256MB and aftermarket 1GB modules. Corrosion? Badly seated? Dunno seems to work.

Got a new (NOS?) NIC coming in at 9.99€ which should work.

Quick google suggests that the A1027 can be found in (non US) PowerBooks so I might dig through my pile of spare parts, but not a priority.

Kinda unrelated side note:

Putting in a RadeonHD from a MacPro will make the G5 fans spin hard, it will boot, but MorphOS still won't use the card.
Not that I expected anything more ;)

Quote:

Early PowerBooks G4 and most iBooks G4 used A1027 cards for WiFi.

Alas, you will also need an antenna that fits (as the internal antenna connector won't work without some kind of adapter). The connector needed for A1027 is MCX male AFAIR and the internal antenna connector is U.FL (needs double-checking).

Well quick rumble through the heap only showed 1 card installed in a 5.8 which only misses the upper case/display that I might want to recover at some time.
Thats not "early" so, no idea if it would fit at all.

Oldest one would be a 5.5 but thats in parts and I haven't found that module yet.

Antenna should be no problem as I have at least 2 broken 17" displays where I could pull them out.
