Hi i have two G5 11,2 Macs at home one 2.5 Quad and a 2.3 aircooled. I saw this video on youtube from Chris Edwards. He swapt the cpu from his 2.3 11,2 to one dual core CPU from G5 Quad.
Would it be possible to just swap the aircooling from the 2.3 into the 2.5 quad and remove the watercooling and one cpu from the quad? So it would be then a G5 Dual Core 2.5 Machine that is aircooled?
I know i could do it the other way round. But the Quad has a MorphOS Key so i had to buy a new license or at least bug Frank for a license swap.

It should work, but remember the PSUs in the Quads are inefficient timebombs ( worse than the smaller ones in the dualcores).

What you mean with timebombs?

Much more likely to fail compared to the smaller ones.

Yeah, I second Kronos on this...

Go to one of the single processor versions and swap the cpu like many of us have done.

To many headaches to deal with the quadcore systems...

You will have a CPU as a backup as a bonus :)

You could always buy another license so you could hop back to the other if needed. That is what I did. I have a spare ready to go if my main system ever failed.

Good luck!

To be honest I'm not sure if I would bother upgrading a 2.3GHz model for such small gains.
With a 2.0GHz base you get +25% both for CPU and front side bus.

So yeah, sell the quad, pay 79€ and enjoy the 2.3 as it is.

Ok i will think about it.
But looks like i have to get a new GPU the 4550 seams to be dead. Didn't power up the G5 for some weeks and now the G5 starts but i have no picture.

Do you hear the fans on the video card slow down, indicating that morphos is running?

If you are using an SSD, I recommend trying to boot a few times to see if it comes up. If your using an HDD then card likely bad.

Bring it to Neumünster and we can test some of my surplus cards.

They were all in the 15-25€ range, so that should work out.

Writing this on my G5 Quad. I removed one CPU and switched it to air cooling.
So far everything seams to be allright.
And the loud noise is gone. I guess the Pump of the water cooling did all the noise.
The Problem with the GPU was the Pixelclock it was to high. Don't know how that happend. It was working befor and i didn't changed anything.
Temps are good with heavy load the temps go up too 57° Celsius.

@matt3 the Card i use is passive cooled

@Kronos bring the GPUs to the meeting.

O.k. will also bring my little powermeter, really curious how a crippled Quad compare to an upgraded dual-core.
