Replace powermac mdd single 1ghz processor with dual processor

I want to know if i can if put a dual 1.25 or 1.42 ghz processor in my single processor machine. will it work because what i understand is that i have the slower bus speed of 133 and the dual processor machines have 167. will that matter?

Aftermarket processor upgrades would have to be specific to the Mirrored Drive Doors model. The CPUs for earlier models will not work. So you would have to follow the recommendations of each manufacturer. Maybe someone who has added one can chime in with a recommendation. Otherwise, try:

Single screen KVM with dual screen setup

So here's the deal. I have dual 20" cinema displays hooked up to my Quad. I took one of the displays and hooked it up to my IOGear DVI KVM (http://www.iogear.com/main.php?loc=product&Item=GCS1764) so that that display could be shared with my Powerbook G4 and my Core Duo MacMini. However, when I change ports on the KVM, the secondary display "disappears" from the PowerMac and it starts freaking out. Sometimes it will just try to detect the screen (constant signal flickering) for a minute and then give up and operate as a single screen system but most of the time it tries to detect the screen for 2+ minutes until it just crashes the whole computer and then I have to reboot the PowerMac.
Any ideas?

Removing pin 16 on the DVI cable to the PoweMac might help. See the last item in: <http://www.gefen.com/kvm/support/faq/>

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.

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.

Dual 1ghz processor G4 with FCP 6

Hi. I've seen this question around, but not specifically for my machine, so here goes:
I have a Mirrored-door dual 1Ghz processor G4 currently running FCP 5.whatever the last update number was. I'm now back in school and the school has Studio 2 (FCP 6). I'm happy with the system I have, but I can't take files back and forth from home to school, so I'm thinking about getting Studio 2 at home. I know right off the bat that I'll need a new video card, but I noticed that the minimum requirements are for a 1.25ghz G4. Will a dual processor 1ghz work? I'm not concerned with being able to use motion or color at home, just FCP and Soundtrack Pro.
I know that the real answer is buy a new computer, but that's not really an option right now.
Thanks.

Will a dual processor 1ghz work?
No, categorically no, it will not work. I've done this with my Quicksilver 1 gig dualie and this has been asked a few times in the past week. Search the board for my answers.

Logic on a dual 1ghz processor machine.

I have a quicksilver dual 1ghz processor machine with 1.5gig ram. The minimum requirement for Logic is a single 1.25ghz processor. It would "seem" like a dual 1ghz processor board would trumph a single 1.25ghz processor. I went to the local Apple store and asked several "genious" and software reps if I could run logic on my machine and the best I could get was "ummmmmm, good question...."
Does anyone know if I can run it? Apple doesn't - and if you buy the software and it doesn't work, you can't return it.

I was using a G4 MDD 1 ghz dual when I first upgraded to LP8. it did work but it was much slower and problematic than LP7. I found a good deal on a G5 on ebay and I am very glad I went that way. You will get a warning message when you instal Logic Studio, but it will work

What's the deal with dual processors???

The whole dual processor thing has been bugging me for some time now. If I have a dual 500mhz processor, is it the same as a 1.0ghz processor, worse than one, better than one?! Are there other factors at play? In my limited scope, if you had a dual 500, 533, whatever, it would be the same as a single 1.0ghz - and yet these dual processors are priced much cheaper. I really am at a loss as to how computers do their processing, and how to compare single processor G4's and dual processor G4's when making a purchase.
Insight would be greatly appreciated!

And you shouldn't forget, the future is multiprocessors. There is a limit to miniturization, and the solution seems to be multiplication. So operating systems and applications are increasingly going to be multiprocessor-aware. Maybe a perfect example is the upcoming MacOS release, Snowleopard. Apparently, there will be almost no cosmetic changes. The changes will essentially be 'under-the-hood'. And you can bet, that some of those changes will be increased efficiency with respect to multiple processors.
So what's the deal with airplane peanu...err, dual processors?
The advantage, theoretically is, having more workers to do the work. Your 1ghz processor is like a worker who can lift 100kg, and your 500mhz are like workers who can lift 50kg each.
So where's the advantage? If you have a farm with 40 kg hay bales in the field that you need to pick up, your better off with two workers than one right? Or 8 workers in the case of a 8-core MacPro. So an multiprocessor-aware operating system, doles out the work much more efficiently, spreading the tasks around, or spreading a single task around in pieces (if the app is so written).
You've heard of render farms? The multiple computers used to render the frames of animated movies? Its the same principle. Having computer 1 render the first 1000 frames and computer 2 the next, the project gets done within a lifetime. If they had had only one computer, ToyStory would still not be finished.
Its the future. Just wait till the end of this year for example. Nehalem chips will be sporting even more processors.

Power Mac MDD G4 1.25 Single Core vs. Dual Core

I am purchasing a 1.25 MDD G4 that has the single core processor. I am going to be using it for music recording and creation.
Am I going to wish I had the dual core? Or will I not notice the difference? I was previously using a 700mhz imac with 765mb of ram and overloaded it pretty quickly.
This machine, with 1 (which is has) or 2 (which I might install) gigs of ram should outshine that pretty significantly even with a single core shouldn't it?

Dual if you can, especially if you're looking to go to Leopard during the life of the machine. Single G4 CPU and Leopard is painfully slow, even at 1.67GHz.
Even the current entry level iMac blows away most of the G5's, except maybe the quad cores) so G5's should be reasonably priced.

Replace 1.6ghz logic board with dual 2.0?

Is it possible to swap out the logic board and cpu of a 1.6ghz G5 with a dual 2.0 logic board and cpu?

i mean staying G5 the entire time, just going from
single 1.6 to dual 2.0 (not dual core).
I think you could do what you're asking about. The CPUs and motherboard go as a pair, so you can't drop a 2.0 GHz CPU into a 1.6 GHz mobo or vice versa. But, replacing the mobo and CPUs as a pair should be OK.
You'll likely also need to replace the power supply. The 1.6 GHz machines had a 450W power supply, and the 2.0 GHz machines had a 600W power supply.
However, you might want to talk with an authorized Apple repair center to see if there are any other technical hurdles that I've not mentioned.

Replace multiple whitespaces in a string with single one

Can someone help me out?

PowerMac MDD 1.25 Dual G4 won't start..

Abruptly this PowerMac MDD 1.25Ghz Dual G4 won't start up. The button lights up, but there is no other reaction from the PowerMac. I have already reset the PMU on the logic board. I have replaced the CMOS battery. I removed the hard drive and copied important data off it. Any other suggestions before taking it to my local Authorized Apple Repair Station.

wouldn't it be more prudent to just replace the "wind tunnel" power supple
As a matter of troubleshooting, no.
After testing and confirming, yes.
Used and refurbished power supplies are available on eBay.
The 360W MDD PSU, having revamped fans, is the desireable one.
I'm thinking of just taking it in and have them check it out.
A third party repair service might be fine. Apple will just say it's too old.
I'm sure I can replace the power supply myself.
http://www.youtube.com/watch?v=uEfNH1DaJUo
Where is this capacitor located? inside the power supply?
Inside, where it is very dangerous for the non-trained to access and repair.
PSU components hold deadly charges long after they are unplugged.

Dual-DMVPN Design with Dual Hubs on a single router ??

Hi All,
In DMVPN, in Dual-DMVPN Design with Dual Hubs , can a single router perform the role of dual hubs.
The router has two different internet links. It is intended that when one link goes down, spokes shud connect to the same router onto the other active internet connection. Is this possible ?

Since no one has answered yet, I'll give you the practical answer.
You'll have issues with IPSec and static routing. "DMVPN" itself probably wouldn't have an issue, but it would depend on IPSec and routing to work.
It is easier, by far, to put in a second router. And when you factor in your time to try to make it work (and it may not work), the second router is less expensive.

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance
Labview Lover

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

How to replace Nexus5596 with dual-homing N2K

What is the correct process to replace a FEX parent switch with dual-homing fex?
Traffic should not be interrupted.

Hi
Do you have VPC between Parent Switches & are you running VPC on dual homed FEX fabric ports. ?
If yes Below is the procedure,
1) boot the replacement switch without VPC, peer-links & FEX ports connected to it.
2) Make sure it has same Software version matches with the peer switch.
3) enable Pre-Provisioning for slots with appropriate FEX model.
, here find the guide:
http://www.cisco.com/en/US/partner/docs/switches/datacenter/nexus5000/sw/system_management/521_n1_1/b_5k_System_Mgmt_Config_521N11_chapter_0100.html#task_05BB53AD7AFB49CF9A8E4A5C6C37CB38
So, on the replacement switch you will pre-provision the Fabric Extender and configure the ports so it will be ready when you add the module to the RMA SW.
Please make sure you put the appropriate FEX model on the provision slot, otherwise, when connected it will not come Online
Example, FEX 110:
N5K(config)# slot 110
N5K(config-slot)#provision model N2K-C2248T
4) Now keep all ports at Shut down state Then Configure Entire switch that includes FEX host ports, FEX Fabric Ports & VPC peer-link, VPC Domain Configuration.
keep FEX host ports in shut state.
5) keep VPC Role priority on existing switch lower than , new switch
6) Connect Peer-link ports to Peer switch & wait till VPC Comes up-
7) Then connect Fabric ports from FEX to the pre-configured ports on replacement switch
After it comes online Unshut FEX host ports.
I got similar steps here as well

2005 PowerBookG4- Replace Power PC w/ Intel Processor- Possible?

I have a 2005 Powerbook G4, PowerPC, version 10.5.8. I want to know if I can get an Intel (or other) processor to replace the old Power PC, and with that, install the current OS, which I think is now Mountain Lion. In othe words, I want to avail myself of the latest software innovations, and am willing to cobble together the hardware to make that happen, within reason. I like the physical design and architecture of the old G4 and am reluctant to part ways with it. Is this at all possible/practical,, or just too much $$ and hassle? I'm an old school guy who is happy luggin' around an older 'heavy' PC andf can do without tablets asnd such.

Its amazing how many people come in here and always ask this question or same sets of questions over and over again. Can PowerPC G4/G5/G3 be upgradable to Intel? Can I place an Intel processor in my Powerbook??, I don't mean to be rude or come off sounding bad towards those who ask these questions, but its getting rather long in the tooth.
PowerPC Macs, depending on which you have can go as high as 10.5.8 Leopard and thats all. Some can only go as far as 10.4.11, but those would be your low end PowerPC machines.
The best PowerPC Macs for Leopard would be the following:
G4 MDD dual 1.25/1.42
Any upgraded G4 based machine with a strong graphics card for core image(speeds up video acceleration under OS X) and processor. e.g.: Sawtooth G4 500 upgraded to 2.0Ghz PowerLogix.
All G5's in my opinion should have no problems running Leopard up to and including 10.5.8.
G3's are best suited for Tiger 10.4.11 and Panther 10.3.9(Low low end G3s).
A rule of the thumb: if its PowerPC it can't be upgraded to INTEL, period!
Hope I wasn't too rude.. didn't mean to ruffle any feathers here. Just tired of seeing the same thing over and over again.
enough ranting! Now, who's up for installing Leopard on their PowerPC Mac?
