Dual 1.25 ghz processor in a dual 500 mhz GBE?

I have a dual 500 mhz processor Gigabit-E G4. Would a 1.25 ghz processor from a MDD G4 physically fit in there and boot? I know the multiplier would be different, but if its just a little bit slower, that wouldnt be a big deal, because it would still be faster than the 500 mhz. Also, how much slower would it be?
thanks

That is a little different question.
AGP Graphics through Digital Audio use a 3-lug mount and a 300-position rectangular data connector. The Digital Audio moves the processor socket to the back rail, where there is a lot more room for multiple processors, and replaces translucent shroud with fan assembly with the small black rubber fan assembly.
The Quicksilver and later use a 4-lug mount (the first three are compatible) where the fourth lug carries +12 Volt power. You might be able to use a processor as fast as the Dual 800 (top of the line \[original] QuickSilver) if you grabbed +12 Volts off a Hard drive Molex connector and bolted it to the fourth lug on the processor.
As far as I know, the 300-position rectangular data connector stays compatible. I have never seen articles suggestion you have to change stuff to move to a different group of processors, but you should check places like:

I use a 2003 FW800 MDD desktop, with dual 1.25 GHz processors, and OS10.4.11, and with native Bluetooth card, won't recognize a newer Bluetooth Headphone set as an Input or Output device in System Preferences

I use a Mac 2003 FW800 MDD desktop with dual 1.25 GHz processors, 2 GB memory, and a native Bluetooth card installed. I use OS10.4.11. The FW800 was the only MDD that could use Bluetooth natively, as an optional installation. I use the installed Bluetooth to run an Apple Aluminum Keyboard, and would like to use it with a new (2010) Samsung SBH-600 Bluetooth Headphone set, but, although the set will pair with the computer, and is recognized in both the System Profiler, and the Bluetooth section of System Preferences, it is not recognized in the Sound preferences section of System Preferences as either an Input or Output device. Only the installed external Apple speakers are recognized. I'd like to know if there is anything that can be done to make the Bluetooth system installed work with these headphones - either something that can be changed in the computer settings, or an added external Bluetooth device with different Bluetooth capabilities.

It it may be that you are running either an outdated BT software or the firmware of the card is not up to date.
What version is your BT software? Is it later than 1.5?
http://support.apple.com/kb/DL1209
Firmware:
http://support.apple.com/kb/DL354
Along with the firmware, it is likely that the headphones require a later BT revision than you are running. The headphones need rev.2.
You may need to move to Leopard for support.
http://support.apple.com/kb/DL889
It also may be that headphone support is limited to iChat or the like in Tiger.....
If you go to a USB BT dongle, D-Link often gets the nod as having native compatibility in OS X.

Using A Dual 1.25 Ghz Processor Card in a 2002 QuickSilver formerly DP 1Gig

Hi There,
Is there any technical reason why a Dual 1.25 Ghz Processor card wouldn't work in a former 2002 QuickSilver Dual 1 GHz Machine?
Thanks For Your Time,
Eric
G4 Mirror Door 1.25GHz Dual Processor CPU Board MDD..

Just say you got it to work it would blow, believe apple makes everything different even if it looks pretty much the same, its best not to try stunting, in modifying it will cost you, just try E-bay your bound to get some deal.

Dual 1.25 Ghz processor swap into 867 quicksilver?

Hey… I know this is going to sound like an odd question, BUT… I am considering upgrading my 867MHz Quicksilver processor, and tried a 1.5GHz upgrade chip from OWC. It didn't give me the performance boost I was hoping for. I have an opportunity to take the processor out of a dual 1.25GHz Mirror Drive Door PowerMac G4… is it possible to place the processor & heat sink from this machine in my older 867? I think the dual has a 167 bus vs my slower 133 bus, so I don't know if that's a problem. Thanks in advance for the help!

Hi
unfortunately processor cards from MDD G4s aren't compatible with Quicksilver (and earlier) G4s as they use slightly different architectures and possibly even different processor sockets. That's partly why OWC (and other third party) processor upgrades cover models from the AGP/Sawtooth G4s upto the Quicksilver 2002 G4s, but aren't compatible with the MDD or FW800 G4s.
The fastest 'Apple original part' upgrade would be a dual 1GHz from a Quicksilver 2002. I swapped my single 800MHz for a dual 1GHz (pulled from another Quicksilver) and the difference in performance was very worthwhile.
Having said that though, most benchmarks show a dual processor G4 is around 40% faster than a single processor running at the same clock speed, so I'm not sure a dual 1GHz would be much (if any) faster than a single 1.5GHz. Also which ever processor upgrade you choose, you're still stuck with the same relatively slow 133MHz system bus, which will impact real world performance.
I hope this helps.

Can the Dual 1.8 GHz processor be replaced with the Dual 2.5 GHz?

I don't know a lot about processors and compatibility, so I was wondering if anyone could tell me if this upgrade is possible.
Thanks!

Hi-
A lot depends on the series of the G5. Even within a specific series, say late 2004, processors of different speed had different boards, power supplies, etc. There are other factors beyond the physical as well.
Even the action of removing and replacing the same processor requires the system to be thermally calibrated. There is more to a G5 than the individual components. G5's are the sum of the components, some tied to another with no alteration to even series possible.
My thought is a simple processor swap as described would not work.

Can FW800 133 MHz board from single 1 GHz machine take a dual processor?

I've read in more than one place that the logic board from the 1 GHz FW800 machine can't be used with ANY dual processor. Can anybody tell me with a reasonable degree of certainty whether this is true or not?
Please don't bother answering based on general principles. I already believe -- tell me if I'm wrong -- that every other MDD FW400 or FW800 board CAN take a dual processor and, except for this question, EVERY processor will work EITHER with EVERY 133 MHz board OR with EVERY 167 MHz board.

From my experience the processor card should be compatible, but don't hang me if I'm wrong.
This page showes how to set different multipliers = bus ratios.
So, according to the default multipliers for the MDDs, you get:
6.5x 133 MHz bus = 864.5 MHz CPU (867 MHz)
6.0x 166 MHz bus = 996 MHz CPU (1.0 GHz)
7.5x 166 MHz bus = 1,245 MHz CPU (1.25 GHz)
Thus, if you put a Dual 1.0 GHz onto a 133 MHz board, you'd get not 1.0 GHz but 800 MHz instead (798 MHz to be exact). The same goes for the 1.25 GHz where you'd get 1.0 GHz (997.5 MHz), and for the 1.42 GHz where it'd be 1,1 GHz (1130 MHz, multiplier 8.5x).
6.0x 133 MHz bus = 798.0 MHz CPU (1.0 GHz → 800 MHz)
7.5x 133 MHz bus = 997.5 MHz CPU (1.25 GHz → 1.0 GHz)
8.5x 133 MHz bus = 1,130 MHz CPU (1.42 GHz → 1.1 GHz)
So, if you alter the bus speed of the board (see here, link is from the xlr8yourmac page linked above) you will be able to use the Dual processors for the 166 MHz bus on your 133 MHz board, then overclocked to 166 MHz, at their designed speeds. If you don't what to change the boards system bus speed the processors will just be underclocked, thus run slower – with all the advantages like less power consumption and less heat emission together with a prolonged lifetime.
To fit the 133 MHz system bus you would have to change the multipliers on the processor daughter card to run at the processors native speeds.
Just one example:
1,000 MHz / 133 MHz = 7.5x
So, if you'd want to run a Dual 1.0 GHz processor on a 133 MHz system board you'd have to alter the multiplier from 6.0x (for the original 166 MHz system bus) to 7.5x (for your 133 MHz system bus) – the resistors to change the multiplier reside on the processor daughter board.
That said, keep in mind that this procedure is *NOT tested or confimed*, but it seems logical, doesn't it?
I had a OWC Mercury Extreme 1.4 GHz processor upgrade placed in a Gigabit Ethernet replaced into a Quicksilver (2001 version). As you can see here, it had set the multiplier to 14x to have it run at 1.4 GHz on the Gigabith Ethernet (100 MHz system bus) and I had to set the jumpers to a multiplier of 10.5x for the Quicksilver (133 MHz system bus).
Thus, if I had put the OWC Mercury Extreme running at 1.4 GHz in the 133 MHz bus Quicksilver unmodified back into the 100 MHz bus Gigabit Ethernet, it would run at 1050 MHz (roughly 1.0 GHz).
That's it. There wouldn't be more to it than that, but the latter source (for changing the motherboards system bus speed) states that Apple put in some protection on the processor daughter card to prevent increase in system bus speed if no dual processor is present. Since this doesn't apply to you as you stick to your 133 MHz system bus it shouldn't bother you.
*But don't blame me* if it should turn out to be completely wrong!
Cheers,
Andreas.

Flash 8 Pro freezes on Mac G5, dual 2,5 GHz

Ever since I upgraded from Flash MX 2004 Professional to
Flash Professional 8 on my PowerMac G5 it doesn't run. All I can do
is
open the software but as soon as I click on a menu or a
button, whatever, like changing the size it freezes instantly. I've
searched the forum and every possible place to find any answer that
can solve my problem but it seems like I'm alone with this, I can't
find any information anywhere. I've even tried to un-install and
re-install Flash again but same problem still occur - freezing. Has
anyone had the same problem on a Mac G5 with dual 2,5 GHz
processors, in that case – what did you do to solve the
problem? I'm out of ideas and can't figure out more.
My specs are:
PowerMac G5 (2005), dual 2,5 GHz processors
Boot ROM-version: 5.1.8f7
Systemversion: Mac OS X 10.3.9
Kernel-version: Darwin 7.9.0
1 GB RAM memory
Apple 20" flatscreen, 1650 x 1050 pixles resolution
Flash Professional 8, upgrade (Flash worked fine before the
upgrade!)
All other Studio softwares I upgraded run and work great,
except for Flash.
Please help me, I need HELP!

I also have to add: I can't even click on Preferences in
Flash, nothing. It freezes instantly. It run as long as I don't
touch ANY button or menu in Flash, as soon as I do anything, touch
a menu or button Flash freeze.
Anyone know what to do? Or shall I throw it out and install
an earlier version like MX 2004 Professional, that version of Flash
worked. Please, please, please... Help.

Power Mac G5, Dual 2.5 GHz wont' boot

My Power Mac Tower, with Dual 2.5 GHz processors was off. When I push the start button, the white light flashes, the fan turns on then immediately shuts off. I suspect it is the power supply, is there any way to verify that it is the Power Supply before Igo buy another one.

I would try things in the following first......
Have you ever changed the PRAM battery? Your Mac is at the age where it may be depleted.
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
For G4's and earlier models, check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject. Most of his tips pertain to a G5 also.
G5 Tower users check Apple KB article HT2580 on DIY (Do It Yourself) Instructions. Click on the PDF for Battery.
Here is the late G5 SMU reset.
Early G5's use a PMU reset and the battery shown in the tutorial. The battery for late G5 (2005) + G5 iMacs and earlier iMacs, Mac Minis and Intel Tower Macs is this one.

Software for Gigadesigns Dual 1.7 ghz

Hi I have a Mac G4 (AGP Graphics)
with a Gigadesigns Dual 1.7 ghz Processor
in the system profiler it is reading
Number Of CPUs: 2
CPU Speed: 0 MHz
System Version: Mac OS X 10.4.11
I bought this computer on ebay 6 months back with the software on it
I had no problems
I been using Garageband For some time now
But recently I wanted to use Logic to see if it would send midi out.
I never used Logic I figured it was like Opcode Studio Vision.
I lunched Logic for the first time and got this error
• Logic Pro requires that your system have a CPU speed of 500.00 MHz; this system has a CPU speed of only 0.00 MHz.
I tried to see if there is software for the Gigadesigns Dual 1.7 ghz Processor to make it stop reading CPU Speed 0MHz
is there any software for Gigadesigns Dual 1.7 ghz Processor?

Hi
You need Giga-Meter 1.0.1. reinstalled. Then your mac will read CPU speed.
Click on my name and send me an email and I will send you a copy.

Is it OK to Swap a Dual 1.25 Ghz Logic board with a Dual 1 Ghz one?

I need to replace the logic board in my original Dual 1.25 Ghz MDD Powermac G4. I found one that came from a Dual 1 Ghz Powermac. The person selling it says that they are identical.
Anyone know if it is alright to install the Dual 1 Ghz logic board with Dual 1.25 Ghz processors (and in the dual 1.25 case)? Thanks.
Dual 1.25 Ghz MDD Powermac G4 Mac OS X (10.4.8)

I have a dead dual 1.25 MDD. Indications are that the problem is either the logic board or the processors. I have heard the MDDs are known to have more logic board failures that other Macs, so I am thinking about replacing that...
Does anyone know how much could I expect to pay for the just the logic board?

Dual 1.8 GHz G5 only running of one processor

My dad has a Dual 1.8 GHz G5 and had problems in the past, one of the processors went out. He took it to a repair shop and they switched it to run only off one processor. Apparently after they repaired the computer, they didn't tell it to run on both processors. We found out when we went to About this Mac. How do I tell it to run off both processors again?
G5 Dual 2.7 GHz, 15-inch PowerBook 1.5 GHz Mac OS X (10.4.3)

Nap is a power saving feature.
The following processor states are defined:
■ Run: The system is running at maximum processing capacity with the processor running at full speed.
■ Idle: The system is idling; this is the default state. All clocks are running and the system can return to running code within a few nanoseconds. If the system has no work to do, it will be in idle mode.
From idle, the processor will enter deep nap state when the system is power-stepped to half frequency. In this state, the processor’s internal frequency is reduced to 1/64 of the maximum frequency. The processor frequency is returned to normal on exit from idle. The exit from idle takes a bit longer than the regular idle nap but is still in the nanoseconds.

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor?

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor? Everything on my computer has been running so slowly in the last few weeks. Have I finally outgrown OS 10.4.11? Would there be some other problem that would sudden make all my speed take a nose dive? I have 8.5 gigs of RAM... Please advise!
Thanks! Matthew

Everything on my computer has been running so slowly in the last few weeks.
First open Console in Applications>Utilities, see if you have reapeating messages.
How much Free Space do you have on the Hard Drive?
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Is there a processor upgrade available for a Dual 1.8 GHZ G5?

I am looking to upgrade a Dual 1.8 GHZ G5 to 4 processors if that is possible?

Not 4 CPUs, but somebody here in the last month or 3 changed to higher rated G5 CPUs on a slower Logic board, which I didn't know would work, not sure which speeds it was & can't dind anything on Apple of course.

Can I add a processor to my single 1.8 Ghz, making it a dual?

Can I add a processor to my single 1.8 Ghz, making it a dual? If so, where can I find installation instructions to do that? Thanks.

I've heard from various places that the G5 boards (excluding the 1.8GHz G5, 600MHz FSB) share a common design. However, the SP ones lack a physical socket for the second processor even though the board traces are there. That opens up possibilities if you're adventurous.
I recommend selling your current G5 and using the money towards a dual or quad G5 if you're not too attached to it. It's the simplest solution and would result in a faster system overall.

I have the following Apple Computer: Dual 1.25 GHz PowerPC G4, 2 MB per processor. Can I put install new Intel Xeon processors in place of the current ones to bring my Mac up to the MacPro standards and so I can install the new Mac software?

I have the following Apple Computer: Dual 1.25 GHz PowerPC G4, 2 MB per processor. Can I put install new Intel Xeon processors in place of the current ones to bring my Mac up to the MacPro standards and, if so, can I then install the new Mac software (Lion)?

As has been clearly stated, no, no, and no.
If such an upgrade were possible, it probably would be more money than it would be worth.
If you're running a G4 (dual-processor even) you can pick up a used Mac mini (intel that is, and something from 2010 or newer would be the best bet) that will be screaming fast compared to a G4.
Once upon a time, processor upgrades were not only possible, but a good deal, and a relatively inexpensive way to get more life out of your Mac. I upgraded a G3 tower to a G4 for few hundred dollars, and I was glad I went that route at the time. Finally, CPU upgrades, at least as far as I know, aren't available anymore.
