Dual VS. Single processors for audio?

Bearing in mind that a dual processor Sawtooth is faster than a single, which is overall a better computer for running audio applications? For some reason I seem to remember someone telling me a few years back of some problems with the duals in this regard.....but I'm probably mistaken. If anyone could clear this up for me it would be great!

well, earlier version of pro tools (earlier than 7) do work on dual processor machines, but they can only use one processor! The only advantage is that you can set CPU usage in Pro Tools Hardware setup at 99% while in single processor machine you can use only 85% of processor capacity. You gain a 14%. That is because the other processor can take all the load that is not generated by Pro Tools usage. Of course all other application can be run on the free processor so that you can use multiple application with almost no problems but Pro Tools will only use that one single processor. Hope this help.

One Image for dual and single processor G5 machines

I'm working in a lab that has both single and dual processors G5 machines. There is only one image for both machines and I suspect that we have a few bugs with the single processor machines because of this. Has anyone else used one image for both single and dual processors? Have there been problems. I'm wondering if it is necessary to create two separate images.
mdinger

There is not difference in the images, but you might have problems with the single G5 machines and 10.4. Did you do the firmware upgrade?
I have ~10 single G5 and 25 dual D5 machines netinstalled from one image without trouble.

Dual or single processor?

I've been using a dual 450 and I have no idea what I would lose if I move to an iMac G5. I do a lot of downloading and uploading of large files to a server, and use Photoshop, InDesign, Dreamweaver and Illustrator heavily.
Can someone please tell me what the advantage is of having a dual processor instead of a single?
Thanks!

Hi Designcat;
Generally speaking the primary difference is that if the application you are using is able to fully load the CPU on a single processor box, you will noticed degraded performance if you attempt to multitask. On the other hand if you have a dual processor that likelihood of tying up both CPU is much less so the possiblility oif multitasking is much better.
Having used both, I think that multiple CPUs is the way to go, since OS X is based on UNIX and is able to utilize multiple CPUs very well.

Possible to Swap Dual 1.25 Processors for Dual 1.42?

I have to replace my processors and perhaps the logic board of my original Dual 1.25 Ghz MDD Mac.
Does anyone know if the [FW800] 1.42 Ghz processors are compatible with the 1.25 model that preceded it by 5 or so months? Additionally, would the logic board work within the MDD mac?
Thanks,
C
Dual 1.25 Ghz MDD Powermac G4 Mac OS X (10.4.8)

Based on some net research, mostly on the xlr8yourmac site, I found that the swap has been done by several Mac users with dual 1.25 GHz MDD G4s. The mods were made over a year or more ago and there weren't any follow-up qualifiers, so they apparently were good upgrades.
So, if you have to replace the dual 1.25 MHz processors anyway, going to the dual 1.42 GHz processors is a workable swap. However, the upgraders noted that the performance gain was modest, so doing it for performance alone probably isn't cost justified.
The information I found did not include any mention of logic board swaps and did not specify whether or not the processor swap affected the ability to boot into OS 9. I don't think it is likely the boot encoding in locked into the processors based on personally upgrading several processors on old Macs over the years.
Good luck with your processor swap.

Can a Power Mac G5 2.7 dual processor be run as a single processor?

This is in relation to my last question that I may have mis-worded,
Can I run a dual core, dual processor, as a dual core, single processor, and if so, how do I do this?
This is the info on;
About this Mac:
Power Mac           G5
Machine Model     7,3
CPU type             Power Mac G5 - 3.1
Number of CPU's 2
CPU Speed          2.7
Any Help,
Thank you.

Yes. (but yours is a dual processor, single core each processor)
It may be run as a single processor by disabling one processor.
While booted normally, in Utilities, open Terminal and enter the following:
$ sudo nvram boot-args="cpus=1"
To re-enable the 2nd cpu
$ sudo nvram boot-args=""

PowerMac G5 Image across single, dual, and quad Processor Macs

Good Day,
Our organization is preparing to roll out Tiger. To streamline
this process we have decided to create images for each Mac family in
use. I know I need to find the newest possible model to create the
image but what is the rule for single, dual, and quad processor macs?
Can we use an image created on a quad processor PowerMac on the
dual/single processor PowerMacs?
Thanks

Macs of different models and vintages may take different restore disks. The disk image method of doing this kind of work may or may not work. Use the original disks when faced with different releases or different models. See this article:
http://docs.info.apple.com/article.html?artnum=25784
So a dual-single processor transfer will not necessarily work.
In addition, there are license agreement considerations.
I would not do it unless you know you are in the clear on both accounts.

Migrating from single processor to dual processor Callmanager

Hi Networkers,
had anyone install a Callmanager 4.1 dual processor version of CM4.1-K9-X345D= before in a single CPU in a dual processor capable server before.
Can it work in the first place?
Had anyone successfully migrate it to a dual-processor later on?

I dont think there is any difference in Callmanager software for a dual processor versus single processor server. For 7845 (dual processor) the hardware detection disks may be different from the one for single processor (7825, 7835)
Migrating from one to another is as easy as taking a BARS backup from one server, build the other server to the same version and restore it. (Make sure server name and ip are the same for both servers)

Expanding a single processor G5 to a dual processor

Hi , I have an early 1.6 single processor G5. Is it possible to add another processor to this computer? Thanks for any help.
Also, Will I have any trouble running panther on this machine? I am now using 10.3.9

Depends on the MLB. Some of the First generation SP G5's have a MLB with the circuitry and connector for a second processor. However if this is the case it can ONLY take a second 1.6 GHz as the board will be set up as not to take anything faster than 1.6.
A dual compatible MLB should also have 8 DIMM slots, as far as I know the 4 DIMM MLB does not exist with dial CPU connectors.

Will moving a dual 1.25 processor to a single 1.25 motherboard work?

I have a dual 1.25GHz MDD but suddenly it will not start. No lights and no fan at all. It's just dead.
I have replaced the power supply, but that did nothing. I am assuming that the motherboard is dead. I have a single processor 1.25GHz MDD that's working and noticed that the motherboards look identical.
My question is: Can I take the processor from the dual 1.25 and put it on the motherboard of the single processor machine? I guess, my concern is, do both machines use identical motherboards. If so, this should not be a problem, but before I do anything I want to find out for sure.
Thanks for any help you can provide.

I have the same issue, a suspect MDD2003 G4 MB. My wife yanked the ethernet port from the motherboard when she unknowingly tugged at the cable. The part number is 820-1476-A which is the same as the part number I see available for DP 867 units from before 2003 in several eBay auctions. Does anyone know if the 820-1476-A logic board is the 167MHz bus version? I have a secondhand DP 1.25MHz G4 I want to install but I am getting only power light and fan, no drive or chime on boot with my suspect 820-1476-A logic board...

Trying to upgrade from dual 500MHz to single processor

Question 1
My Mac G4 GE has a dual 500 Mhz processor installed. Is it possible to upgrade to a 7447, 7448 or 7455 single processor or do I have to stay with a dual processor for my G4 to work?
Question #2
Can you tell me when the upgrade will not help anymore since my G4 has a 100Mhz Bus or maybe any other hardware that will limit the processor up to a certain speed?
Thank you guys

Hi-
Is it possible to upgrade to a 7447, 7448 or 7455 single processor
Yes.
do I have to stay with a dual processor for my G4 to work?
No.
maybe any other hardware that will limit the processor up to a certain speed?
The processor will run at stated speed.
Any hardware that is faster or more powerful than the component being replaced will enhance performance.
Can you tell me when the upgrade will not help anymore since my G4 has a 100Mh
RAM is the only thing that will not be upgradeable, as far as speed. Larger capacity is no problem, and will help performance.
Of course, all upgrades are relative to the bus speed and throughput on the bus. As compared to a faster system, the performance won't be as high overall.
But, this is comparing apples to oranges......

Single processor vs dual core

Hi all, hope this is the right place to put this post.
I'm finally about to take the plunge and get a new mac pro, putting my old G4 out to graze.
My question is, which machine is the best? A single processor or dual core?
I work mainly with photoshop, illustrator, indesign, painter and increasingly flash and dreamweaver.
It's going to cost me a couple of thousand so I need to get my choice right.
Any advice would be greatly appreciated.

Hi northey;
It all depends on how intensely you use the apps you listed.
If you just dabble in them never doing anything very intense then single processor will probably be sufficient.
If on the other hand you use these apps to their fullest and with great intensity then the dual processor would be the better choice.
A second point if you use the apps professional to make money then the dual processor would be the better choice since time is money.

Best option for a word processor for the G3 dual usb running Panther

More and more I am coming to rely on my G3 for word processing tasks - particularly research notes and a personal journal.
So far I've tried the simple text editor (quick but poor text on-screen), OpenOffice (being xwindow it's slow to load and slow to update screen) and AppleWorks (good display but no spell checker) -each have problems for me.
What is the best word processor for the G3 running Panther (or Classic/9 for that matter). I need: Quick to load/run, readable text, automatic word wrap, spell checking and a reasonable path to exchange files with my desktop Linux system.

AppleWorks does have a spellchecker; it just is not automatic (check-as-you-type).
In AppleWorks, go to Edit menu > Writing Tools > Check Document Spelling.
I've never used anything (in a major way) except AppleWorks.
A couple of options which you haven't mentioned are Pages in _iWork '06_ (or earlier; the current version has left behind G3 processors) and _Microsoft Office for Mac_.
I'm unsure of how well any of these will integrate with Linux. Open Office may be your best bet there. (I'm just guessing. It seems like common sense to me that Open Office would work with an open OS like Linux.)
Another application which is creating a buzz and sounds like it could work for you is _Google Docs_. There would certainly be no problem with Linux integration there. It looks like it would be easy sharing all the way around and you shouldn't find any incompatibilities as long as you have a decently up-to-date browser.
I'm not sure anyone has developed the "perfect" word processor, but there are some good ones out there. Good luck on your quest.

VISTA Support for Multiple Dual Quad Core Processors

Sorry if I missed this in my search.
Does Windows Vista Home Basic support dual quad core processors?
Windows Help & Support:
Under System, you can view the processor type and speed, as well as the number of processors installed, if your computer uses multiple processors.
Yet I see no mention of multiple processors there -- what am I missing?

Hi -g,
all Windows Home versions (XP and Vista) only support one physical prcossor with multiple Cores.
Windows Professional versions (XP Professional and Vista Business+Ultimate) support two physical processor with multiple Cores each.

From my personal experience, I wouldn't go for an Integrated card. This is one of the most important components for Photoshop, so invest in a decent graphics card (ATI or NVidia). It doesn't have to be a really exepensive one - I have been using ATI Radeon with 256MB of RAM on my Dell Studio for almost two years and it still rocks! (even when I work with 3D in Ps CS5 Extended).
I would also invest in more RAM (this can be added easily - I bought extra 4GB as my Studio came with 3GB).
I wouldn't worry about the processor - I'm on Intel Core 2 Duo - and it works very very well, it's very quick which is very important as I'm training Photoshop.
I hope this helps.
