Hello all!

I own a Quad that's very noisy and I'm therefore interested in other Dual-Core G5's sensor data and how it compares to mine. In particular, I'm curious to get an idea of the range of CPU core-voltages throughout the DC G5 population. I thought starting a little survey here would be most fruitful. I'd highly appreciate anyone's input! Participating requires that you have a Dual-Core G5 (i.e. Dual-Core 2.0 GHz, 2.3 GHz or Quad-Core 2.5 GHz - other G5s don't interest me at this point!), and only takes about two minutes. Here's how:

1.) IMPORTANT: Open System Preferences, enter the 'Energy Saver' preference pane, change to 'Options' and set 'Processor Performance' to 'Highest'. Feel free to change this back to whatever value you had it at after you're done with the procedure.

2.) Halt all wildly processor-hungry processes, such as iTunes ripping, QT conversions, BOINC and the like

3.) Wait about one minute so your hardware sensors' read-out properly reflects the current load condition

4.) Open Terminal and paste the following code at the prompt, followed by the return-key:
Code:
ioreg -n IOHWSensor | awk '/location/ || /current-value/ || /"type"/' | sed -e 's/[^"]*"//' -e 's/" =//' -e 's/location//' -e 's/type//' -e 's/"//g' | awk '{ d=($2/65536); if ($1=="current-value") print substr(d,1,7) "\t" ; if ($1!="current-value") print $0 }' | sed -e 's/ //' | awk '{ if ((NR % 3) == 0) print $0; else printf $0 " " }'
I know this is a bad time to post scripts on a forum, considering the recent trojan being posted at macrumors.com. But rest assured - there's absolutely no need to worry! All this script does is reading-out some of your hardware sensors (namely those for temperature, current and voltage) and formatting the output in a straight-forward manner.

5.) Post the output you receive into this thread, along with some information about your Dual-Core G5 (see my post below)

Thanks to anyone volunteering their time! I highly appreciate it!

It may also be worth mentioning the video card that is in the machine. It can make a huge difference in the noise of the system. When my Quad first arrived it was particularly noisy. After searching around, I found several threads on the topic (for example jebjeb's thread here on MacNN). Seeing the number of success stories, I took the plunge and swapped the cooler on my 7800. The system is very quiet now. There is definitely a noticable fan hum in my quiet home office, but its easily drowned out by the forced air furnace.

As an aside, that GPU Diode temp of 59 at idle seems really high. Before the new cooler, my 7800 was 45-48. Now its hovers around 42-44 at idle. 58-60 at full tilt. (all readings from Temperature Monitor)

I'll post my readings later tonight when I have access to my Quad.

Oh, related to the sensor topic, I wonder what the distribution of pump configurations there are in the Quads. Digging into ioreg I started to get worried mine was broken in that only one Pump was listed, unlike the dual pump disassembly pictures that have been posted. After some fretting and diagnosis, the flashlight through the back of the system test at least convinced me that I have a different configuration from the online photos.

Very good point! Thanks!! Added that to my Info above.

Haven't done this yet, since my Quad is in for repair at the moment, and I didn't want to void my warranty just yet What cooler did you use? Zalman or Arctic?

That's quite a difference! The sensor on my GeForce 7800 GT has always been reading between 50 and 60°C. Interestingly, the number of displays attached and the resolution of the displays seems to make little difference in temperature.
I'll post my readings later tonight when I have access to my Quad.
Much appreciated!

Cheers,

Ron

You mean to tell me that your system only has one radiator pump? Very interesting, indeed! Mine has two, I checked as well. But I'm having my CPU-unit swapped at the moment. I'm wondering what the situation will be when I get it back!

Keep the info coming! Very interesting!

well, concerning the radiator pump configurations, I'm quite sure that I used to have two sensor readings, but now the pump for CPU B is gone. brysonda, are you sure that your Quad has only one pump?

And for the cooler of the GPU: it is getting more and more on my nerves. The only reason I haven't exchanged the cooler yet is AppleCare, which I fear to become invalid after the modification... Any thoughts on that?

I'm away from my Quad for the weekend, so I'll add my info on sunday evening.

Thanks to all of you who posted information so far! Very interesting! Most of the core-voltages appear to be around 1.3 V, which is at the high end of the IBM PPC 970MP specification (1 - 1.35 V). The variation in measured voltages also suggests that Apple is running each core at the lowest voltage at which it runs stably at full clock speed. I've seen as low as 1.15 V...

I'd be very happy to see more data - also from other Dual-Cores, not just Quads.

Thanks again!

Cheers,

Ron

Thanks for your data, Feng! Was Processor Performance set to Highest? Veeery low core-voltage, if it was! That's how they all should be, IMO.

Thanks for all the info, everyone! If you don't mind, could you add info on the approximate date of purchase (e.g. late December 05, or early February 06)? There might just be be some interesting correlations...

TIA,

the voltages stay the same after a few minutes, temperatures are still going up.

further info: quad g5, 2.5gb ram, geforce 7800gt, 250gb hd, built late november or early december
btw just a thought: how exact are these values anyway? i'm pretty sure that there are some measurement tolerances...

Man, got busy and haven't had time... finally got a chance to reply.

I used the Zalman. Worked very nicely. I did get the Arctic Silver thermal compound, rather than using the included tube. I had an old fan from some of my old PCs that I cannabalized the connector from to make an adapter from the video card to the zalman. That way neither needed modification themselves. Put all the parts from the old cooler in storage, that way if I need to put it back on I can. Hopefully I won't need it. Even if the warranty is out the window, it is definitely a lot quieter.

Mine will read at around 58 when I've been gaming, but never at idle. I'll post up readings shortly. I have to reboot to get the inlet sensor to read, it shows the problems noted by the Temperature Monitor website, in that OS X doesn't properly wake it after sleeping.

Well, I'm sure insofar as I looked through the back of the system and it looks distincly different from these pictures. I haven't actually seen the pump itself, but the back side heat sinks for the (power supply?) are suspended above the processor boards by copper heat pipes more like the pictures of the Dual 2.5. I may try to get some snapshots with a digital camera, though I'm not adventerous enough to try and take the processors out like the above photos. I can't even see how the heat sink cover is attached.

Well, I did a non-destructive swap of the cooler (see my previous post). If I need to, I could put it back on. Failing that, I still think it was worth it. It may actually be keeping the card cooler overall.

Confusion,
I do have some more corroborating evidence that I only have one pump in my Quad. When watching the temperature graphs in Temperature Monitor, there is a definite pattern. When all 4 cores are computing, seti for example, CPU A Core 1 is the coolest followed by A2, B1, B2... Seems like the logical flow of cooling fluid in the system.

I'm sure there are tolerances, but I expect them to be within a few percent (but that's just a wild guess). I'd expect that Apple's Hardware Test and Service Diagnostics make good use of sensor data to determine the health of a G5-system, and sensors with reasonably low tolerances would therefore be essential.

But that's just speculation - if anyone knows more, please share the wealth!

Cheers,

Ron

Power Mac G5 Dual Core 2.0 GHz
Nvidia GeForce 6600 (256 MB)
RAM: 1.5 GB
Maxtor 6L250S0 (boot)
Western Digital 160 GB (secondary)

Performance is (always) set to 'Highest'.

This baby is very, very quiet. The main noise is actually low-frequency, as distinct from the fan-whine of all my previous Mac's.

Running half a dozen app's, (iTunes, Mail, Safari, Preview, TextEdit, Activity Monitor, Terminal) CPU load is 24-27% thanks to Safari choking on something or other . . .
