PM G5 dual 2.7 RAM

[John Carmonne]

What's the most RAM that can be installed in a PM G5 Dual 2.7? I have 4 1GB and 
4 512MB sticks at the moment and I saw some Crucial 4GB (2 x 2GB) 184-Pin DDR 
SDRAM ECC Registered DDR 400 (PC 3200) sticks. I want to know if I can install 
8 of these in my Mac.

Re: USB 2.0 Card for MDD G4

[Tim Martin]

An option that no one has yet mentioned but one of those you get what you
pay for products.

7-Port NitroAV FireWire 800/1394b & USB2.0/1/1 ComboProfessional PCI Host
Adapter Interface supporting 32-Bit & 64-Bit Bus Systems
(Mac/WIN)

I have been using the above product, which when I researched and bought it
three (or more) years ago was unique and it looks as if it still is - I've
hung various external hard drives upto 2TB raid array off it and used it for
elgato EyeTV (which has been a productivity killer :-) With some drives it
has presented sleep issues to the system but I don't believe that was the
card’s fault. Pricey compared with single function cards but in my Sonnet
Duet 1.8Ghz upgraded Quicksilver has been a very good extension.

It looks like the PRam battery is dead.
This battery holds the internal Parameter Ram settings, including the
time/date.

It's a 3.6V lithium battery, 1/2 AA format.
It should cost 3-5$.

If you Google "powermac G4 pram battery" you should find plenty of info,
including its substitution (quite easy).

Look for:

1/2 AA 3.6 volt lithium battery

These are made by EVERY major manufacturer of batteries in the World.

Most older desktop Macs used these batteries, but these are not routinely
stocked by the "usual suspect" battery sources.

More modern machines, and particularly PeeCees, use a CR2032, which is
also a lithium battery, but is only 3.0 volts.

CR2032s are available everywhere.

FWIW, CR2032s (20mm dia, 3.2mm thk) have a rated open-circuit (i.e., no
load) voltage of 3.6, and a rated load voltage of 3.0.

The CMOS function of Macs and PeeCees doesn't place a very significant
load on these cells (of whatever type), and lifetimes in years or even
decades are not unusual.

For severe service, such as in desert or arctic areas, a BR2032 is available.

Is the PRAM battery needed?

Ok, I'd like some input here…

Is the PRAM battery needed? newer macs, older macs…. please chime in:-) In my 
understanding, this little battery does a whole lot more than just "set my time 
and date".. honestly if that was the case, Apple would've got rid of the thing 
a long time ago?? my 2 bits…. I'm interested in hearing your thoughts/facts on 
the subject.

Thank you to all who replied.

I shut down using the power button.  Booted back up, and the machine
came up in unadulterated 10.5.  No updates applied.

I launched Software Update again, but this time there were only four
updates instead of five listed.   I believe that it managed to install
the iTunes update it wanted to, and maybe that's what stalled the rest
of the process.

This time, instead of letting SU do the update, I chose "Download
Only".  After that, the Mac OS X Combo Update immediately appeared in
the Downloads folder.  It must have been stored somewhere from two
nights ago attempt, but I searched the machine yesterday (using Find)
and wherever it was, it wasn't visible.

Anyway, telling SU to download it caused SU to immediately cough up
whatever copy it downloaded two nights ago.

I ran the installer manually and it worked perfectly.  The machine
booted into 10.5.8 without problems.

However, this whole thing is being driven by a new iPhone, which needs
iTunes 10.5 (or something like that, not my iPhone).  And when I try
to launch the iTunes 10.5 that SU installed, it informs me that it
needs QuickTime 7.5 or better to run.  But the link on the message
leads to a page at Apple's site which just tells me that QuickTime is
built into the OS now and will be updated automatically by SU.

So which of these updates (10 now that 10.5.8 is installed) that SU
wants to install contains the QuickTime update?  Maybe the iLife tools
update?   Or is that Apple page true for later OS's but not for
Leopard?

Once again, I am pushed to a near-murderous rage by how hard Apple
makes it to find a simple thing like older versions of QuickTime
updates.

A google search turned up a copy of QuickTime 7.7 on a page called
Macupdates, so I can get QuickTime.  I'm just upset that I can't get
it from Apple, as I ought to be able.

There should just be an Apple QuickTime page which lists all the
versions with download buttons.  And, in fact, I found a page like
that, and all the download buttons take one to the Apple page which
tells you that Quicktime is built into the system now and not a
separate download, so none of the links on that page actually works.

G.  Sigh.

But, on the bright side, no matter how idiotic Apple Support is, this
MDD is almost configured thanks to the Mac community and despite
Apple, I think.

Thank you again for the help, and for reading my venting, if you're
still reading.  :-)

Yes, no and maybe.  Some Macs, particularly older ones will not start up 
without a PRAM battery.  Some can be jumpstarted without one.  That is you turn 
it on, it doesn't do anything then you hit reset (or cycle the power really 
fast) and it will start up.  Next time you have to do the same thing.  Some can 
start up just fine without the PRAM battery.  

The PRAM (Parameter RAM) stores a number of parameters (hence the name).  The 
number of items stored in it has decreased over the years.  The two most 
important still in there are the startup disk and the video mode.  

Without a PRAM battery the computer can take longer to start up as it searches 
through the available boot devices to find an OS to load.  Oddly enough it 
takes longer to find that there isn't anything there than it does to find 
something.  In one configuration I saw it took about two minutes before it 
started boot due to the large number of possible boot devices.

As to Apple getting rid of the battery if it was only for the clock, I 
certainly hope not and doubt it highly.  It's rather a pain when the clock 
isn't set right and it's also a pain to set it every time you boot.  If the 
computer is connected to the Internet it can set the time automatically at 
startup but that isn't always the case.

Also, I know of one instance when the battery was low (about 2V vs 3.6 for a 
good one) but not totally dead and the computer wouldn't boot.  When I removed 
the battery it would boot fine.

The original Mac used an existing Moto 68000 family part which performed
two functions:

1) a real-time clock, and

2) a non-volatile RAM.

The 3.6 volt battery supplied the power for both functions.

As long as the NV-RAM remained powered, the various "persistent" settings
were retained.

As the Mac became more highly integrated, the entire function of this
RTC/NV-RAM chip was brought inside the LSI, and the NV-RAM portion was
expanded so that more paremeters could be retained when power was off.

So, not only is the TOD clock retained, just about all system parameters
are maintained as well.

Such as: quite a number of settings which are set by System Preferences...

Video resolution, among many others.

The PeeCees had no similar requirement in the very beginning, but the
PC/AT added essentially this very same chip to its architecture * , and
the much more modern PeeCees of today still have the remnants of that
RTC/NV-RAM chip.


* It was perhaps fortuitous that Moto defined this chip so that it could
be integrated into a conventional memory-mapped architecture (Moto-type)
and a I/O-mapped architecture (Intel-type), so it was a no-brainer to
incorporate this very same chip in the PC/AT.

Later, Dallas Semiconductor made a clone of this chip and incorporated a
very long lifetime battery into its package. It is the Dallas chip which
eventually found its way into PC/AT clones.

In 1984 the pram battery was used to maintain power on the flip flops that were 
used to store not only the clock display settings but a bunch of other user 
preferences that needed to be present during shut down.

By 1993 or so I personally was using other forms of static memory that were 
capable of storing the likes of preference values without any external power.  
RAMTRON , a company here in Colorado Springs, was quite proud of its efforts in 
that field called ferroelectrics.

By the late 1990s we had devices that could retain a lot of memory using 
nothing but stored electric charge on the gates of metal oxide , CMOS, devices. 
You needed external power to change the charges on the gates but they would 
remain charged when power was removed.

Now we have whole plug in "disks" that fit in USB connectors. Gigabytes of 
erasable but still non-volatile RAM are simple. Electrically erasable 
programmable read only memory, EEPROM, is the acronym these days. Entire 
operating systems can remain ready to go when power is applied.

Sometime, probably in the very early 90's, the PRAM battery became unnecessary 
except to keep a clock running.

With time servers on the net even that requirement has disappeared for 
connected installations and even for portables that can see a cell phone tower.

The question is just when, by model number, did Apple join the crowd.

My Mac IIFX requires a battery to start up its power supply.  It's an 
interesting feature that makes it possible to shut down on a power failure 
without worrying about fits and false starts as the power company comes back on 
line. That just might be the last Mac that did it that way. It was a part of 
the Apple Desktop Bus that allowed the start up button on the keyboard.

With the passage of time, the "leakage" current of the CMOS circuitry was
improved to the point that the persistent parameters could be retained for
years, even if no battery was present.

However, as the RTC function cycles the circuitry one every 1/32,000-ths
of a second * , there is some external power required for this function.

* The actual crystal is 32,768 Hz, and it can be fine-tuned using an
external variable capacitor.

The "trickle" function works even though the Mac appears to be powered-off.

PeeCee PSUs generally work the same way as the low-powered microprocessor
which performs the power-on-reset function needs a source of power simply
in order to recognize the power switch has been toggled.

Notice that in many cases your USB devices will still be powered, although
not by much, when you power-down your machine.

Old Machine bests New Machine?

[JohnV]

Don't know how specific this might be, but any thoughts and advice is  
appreciated.


My main audio studio system is built around  LOGIC 8 running on a PPC  
G5 (ex video editing rig) 10.4.11

It's a rock

I have a series of short pieces composed for a gallery installation.  
They were developed on the studio rig and work fine.
Because of the interactive aspect of this project in a Gallery  
exhibition, I'm using MAX and  sensor systems that require a newer OS,
The machine that is going into the gallery to run these pieces,  
through a quad sound room installation, is an iMac dual core.


My horrifying surprise is this:
	These LOGIC music projects, that play fine on the G5, cause the  
newer/faster/amazinger iMac dual to CHOKE... playback stops and CPU  
overload box shows up.


How can somethign that doesn;t tax the G5 bring the iMac intel Dual  
to it's knees?

Software failure? Do you run Logic 8 on iMac under Rosetta?
Which iMac dual and which PowerMac G5 do you have? Latest PowerMac G5 with
2x PPC 970mp can outrun iMac Core Duo, but since you have not written any
specifications, I can only speculate.

Software failure?
Doesn;t seem to be, LOGIC doesn;t crash, just stops playback, posts  
the CPU overload screen and asks to resume

nope

WAAAY too much information left out of that.

What is MAX? How well does it deal with Logic files..perhaps you can export the 
finished pieces as AIFF, AAC or MP3? What 'CPU Overload' box? Is there a 
version mismatch between what the newer system expects versus the files form 
the older system? Does your old G5 system use any hardware elements in the 
Logic toolchain?

There's your problem. over 2X the RAM in the G5. Also the Core Duo iMacs are 
not more powerful than the G5's. The Core Duo iMacs were seriously prone to 
issues like this because they're RAM-starved and CPU-starved. The Core Duo was 
just not a very good CPU, the Core 2 Duo was enormously better. 

If you can scare up a Core 2 Duo system and feed it sufficient RAM, I'll bet it 
runs a lot better. An actual new iMac would run rings around the G5 system, 
taunting it mercilessly :-)

The first gen Intel macs kicked G4's asses, but not the dual G5s. The bus speed 
is a third faster for the G5, the cache is smaller but you've got over twice 
the RAM, plus the clock speed is faster.

However the main culprit here is the RAM. My old Core Duo iMac would grind to a 
complete halt for 5 minutes at a time bringing up a Windows VM if ANYTHING else 
was running, and most of it was due to the skimpy RAM.

There's a "fix" for this underpowered iMac problem, it's called the  
"iMac4,1 Firmware Tool", and it can allow you to upgrade the RAM and  
CPU in these older iMacs.


The iMac4,1 came with a 32-bit only Core Duo with maximum 2GB RAM. By  
running the iMac4,1 Firmware Tool you can upgrade the firmware to  
iMac5,1 while will correctly identify 64-bit Core 2 Duo CPUs and  
remove the 2GB RAM limitation.


I think this is a fantastic upgrade to save an older iMac, and in this  
case, seems to be exactly what you need. Order a new (used) Core 2 Duo  
CPU and some more RAM, run this tool, and upgrade your hardware, your  
"new" iMac5,1 will be as fast or faster than your G5. Here's info:
