Dual Processor P4 motherboards

Anyone know if MSI make a Dual Processor P4 motherboard?. Want to get 2 P4 3.2Ghz processor kit etc built into a Vapochill box. Hope they do make one.

You are out of luck Dude , Because as Matter of Fact, I have never even Heard of a Dual P4 Board , I have Seen Dual Xeon, and Dual Itainium Boards, Because Dual CPU Boards are Mainly Used for servers Not For Desktop and Gaming Use, And they Require 24 Pin PSU's Not the Regular 20 Pin Main Connector... And the Only Manufacturer of Dual CPU Motherboards is TYAN....And the Only Semi-Desktop Dual COU Board that I am aware of, is the TYAN Tiger Dual Athlon MP Board, INTEL Never Intended the Northwood, or Prescott CPU's to Run in a Tandam Configuration, Thats why they Came out with Hyper-Threading Technology, and I am almost positive that is the Closest that you will get to a Dual CPU P4.......You Can Build a Dual Xeon Rig but at $1000+ for Each CPU, for a rig that wont be faster at Most Gaming and regular Desktop apps. then a regular Single "Northwood" P4, and Most Definitely Slower then Either of the Extreme Edition Northwoods (As these EE Northwoods are the Closest thing to a Xeon, as the EE also has a 2MB L-3 Cache)........I could be wrong about the Dual P4 Boards Existance but I doubt it.................Sean REILLY875

What is causing a PowerMac G5/2.3GHz Dual Processor sudden abrupt shutdowns

Hi all
I am posting in hope that someone out there can help me solve this very puzzling problem.
The machine: A PowerMac dual processor G5/2.3GHz (early 2005). 1.5G RAM. 250G HD. SuperDrive. Radeon 9650.
The problem: When under some load, this machine will suddenly and abruptly shutdown as though someone pulled the power cord. There is no warning. Just a soft click, and it powers off. The machine can be manually restarted after the sudden shutdown with no problems.
This problem is very replicable. (eg go to a particular website, play an embedded video, and boom, the machine shutsdown. Each and every time.) It was replicated at an Apple Store and at two Apple Authorized Service Providers.
System.log said "PMU forced shutdown, cause = -122"
Before the sudden shutdown, the machine seemed to be operating normally. The fans did not noticeably speed up. Activity Monitor showed no more than 50% CPU activity for each CPU. Temperature on both CPU was around at 70C before the sudden shutdown. Temperature and activity on both CPU goes up and down in tendem.
If I use the Energy Saver system preference to change "Processor performance" to "Reduced", the problem goes away. (As measured by going to the same website and playing the same video. Even playing 5 videos simultaneously did not cause a sudden shutdown.)
What have I done #1: I have reformat the hard drive with a 7-pass security wipe, followed by a clean-install of Tiger which was then brought up-to-date using Software Update. I then installed Safari 4.0.3. No other software is on the machine except Tiger and Safari. (Later installed Hardware Monitor to get me a handle on the temperatures.) The problem persisted.
What have I done #2: I then installed a new PRAM battery and reset PMU using the switch on the motherboard. Resetting the PMU also resetted the PRAM. The problem persisted.
What have I done #3: I then took the machine to an Apple Store. They found that they can replicate the problem easily. But, after 3 days of running the Apple Service Diagnostic, the diagnostic software didn't find any problem. They also did a thermal re-calibration. That didn't help either. Without an error code from the diagnostic software, the only "solution" the Apple Genius offered was to start swapping CPU, power supply and mother board at my expense. And even then, he has no idea which component to start swapping first. (Two independent Apple Authorized Service Providers offered the same non-diagnosis and roughly the same "solution".)
Has anyone encountered such a problem before? What was the solution?
How about an educated guess as to what's wrong?
I want to, if possible, and if reasonable, repair this machine.
Thanks in advance.
Lara

This sounds almost exactly like the problem I have. My G5 is also an Early 05 2.3G. I tried every tip I found on the forums from UPS vs. wall socket to stock RAM vs. 3rd party to booting from external HDs, etc.. I currently have 10.5.8 on it and it's running using the "Reduced" processor setting in Energy Saver prefs.
I have also made a trip to The Apple Store where the AS folks ran their diagnostics but were usable to replicate my problem. I understand they "can't fix it if it ain't broke".
Aside from the "Reduced" setting work-around has ANYONE actually solved this problem definitively? Although I have no interest in spending $1000 to fix this, I can't imagine disposing of it on Ebay.
Assuming this is a hardware issue, this would mark the first insurmountable failure of any of the 10 or so Macs I have owned.
Anyone? Anyone?

Labview and AMD 760 MPX Dual Processor Chipset?

Anyone have any experience with Labview on a dual processor motherboard with the AMD 760 MPX chipset [and, of course, Athlon MP 32-bit CPUs]?
Any gotchas? Any known incompatibilities?
On the hardware side, has anyone had any problems with NI-DAQ or NI-DAQmx?
Any info would be most appreciated. Thanks!
PS: Especially interested in opinions of e.g. Tyan Tiger MPX -vs- ASUS A7M266-D [or any other boards you're familiar with]. Thanks again!

It's years I use 6533 high speed digital i/o making 2mhz output without problems on any hardware.
Today I'm trying to use a Tyan Tiger MPX (double AMD)and .....it doesn't work at all. It's surely a problem with the pci bus, dma and bus master. The total speed is 200KB/sec instead of the desired 2MB/sec. I tryied more than one serial number so the problem is a motherboard's design problem.
I dont use labview but only nidaq drivers and C language.
Now I'm changing the motherboard...at least until someone explain me how to work around the problem.
No problems with MSI and Intel motherboards.

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.

Running dual processor on early Quicksilver board

I'm back to a Sawtooth because my 1ghz dual processor is panicking. Diagnostic in Tiger says the external cache is bad and I understand that I have to shut the cache off every time I boot by if I use CHUD to disable the L3 cache ( which I am very scared to do).
Because I'm more a MacButcher, I figure that running the dual processor on an earlier (733mhz) board which doesn't have the rom to enable the L3 cache might be a possible workaround. I'd then swap motherboards and run the dual limping a little on the earlier motherboard and slip the 733mhz processor in the later board and resell.
Does this all sound possible? What should I watch for? I realize the dual processor would run slower than intended, but it would be better than using the 500mhz Sawtooth and cheaper than buying a new processor.

Hi
I could be wrong, but I thought the level 3 cache was only not recognised if you installed a Quicksilver processor card in a Sawtooth or Gigabit Ethernet logic board, as these originally came with G4 variants that didn't have any level 3 (just level 1 on the processor die and level 2 on the processor card). If the 733MHz logic board is from a Digital Audio or Quicksilver, I wouldn't be surprised if the level 3 cache was recognised, as these shipped with G4 variants that could support level 3 (regardless of whether Apple actually chose to provide the extra cache on some of the models). I'd be surprised if there were any boot ROM differences - I'd imagine it just says if there's level 3 cache available then use it. That way Apple could have one unified logic board/boot ROM and just drop in different processor cards with or without level 3 cache. There are some reports in the CPU Upgrades database at xlr8yourmac.com which seem to suggest a 733MHz Quicksilver can be upgraded with a card pulled from another QS and the level 3 will be recognised.

Z800 dual processor Booting Problem

Hi there,
I got a Z800 dual processor , I tried to operate the motherboard with CPU 1 only without installing CPU 0. now when I turn on the device. the fan of the case spin at maximum and RAM fan doesn't spin. besides bios screen not loading. is that mean my motherboard is gone. or could be bios got corrupted.
Thanks

Dual Processor Board??

I AM STARTING TO BUILD MY NEW SYSTEM AND WANTED TO GO DUAL PROCESSORS, ONLY REASON BEING I PLAY LOTS OF GAMES AND I ALSO DO 3D ANIMATION. I AM ALSO THINKING OF GOING WITH ONE OF THE 3D LABS WILDCAT GRAPHICS CARDS AND "MASS" RAM.
ANYWAYS I HAVE BEEN LOOKING FOR A DUAL PROCESSOR MOTHERBOARD AND I HAVENT BEEN ABLE TO FIND ONE. I AM LOOKING FOR TOP OF A TOP OF LINE BOARD HOPFULLY ONE WITH 800 FSB AND SUPPORTS DDR RAM 400 ALTEAST. THE ONLY DUAL BOARDS I HAVE FOUND ARE LIKE P2 AND P3, BUT I AM LEANING TOWARDS AN AMD FX-51 PROCESSOR RIGHT NOW.
ANY INFO OR SUGGESTIONS WOULD BE AWSOME. THANKS EVERYONE!!!

Hi,
Look under the Server/Workstation boards....
But they only support 1 FX....for Dual support you need the Opteron 2xx series...

Best dual processor G4???

Howdy all...
I'm looking to buy a used G4, and I'm wondering which variation(s) to look for, or if there are any to avoid.
I'm upgrading on a budget, from a Biege 333mhz G3MT. I'll be photo processing in Photoshop, doing graphic work in Illustrator, and all the usual e-mail/web stuff too. I see a number of ebay auctions that look reasonable...but I'm not to familiar with the G4 models. I'd love to snag a new G5...but the budget says no way.
Thanks for any advice.
Kenn
Biege 333mh G3 MT, PB3400 Mac OS 9.1.x

The Adobe products are fine with Panther. That is what I use.
For quite a while in 10.0, 10.1, 10.2, and part of 10.3 I was using Illustrator 8 and Photoshop 5.5 in Classic. Last spring I upgraded to the Creative Suite which is X only. They all worked fine. If you work with fonts then you are going to be in for some education so please read Kurt Lang's masterpiece about fonts with X.
http://discussions.apple.com/thread.jspa?threadID=122011&tstart=0
It is very easy to get yourself messed up with fonts. For me the transition was fairly painless since I had been using Font Reserve in 9 and they were very good about updating for X. Faster than Extensis(Suitcase) who bought them. They are both owned by Extensis now.
When I was migrating to X I frequently booted into 9 because it was familiar. This last year I booted into 9 one time. I still keep a few old macs for running peripherals that don't play well with X but my daily work mac is the one on my profile below.
In general, the AGP macs are the most upgradeable macs out there. While Apple was in it's funk with new products not many changes were made and it was easy for cpu upgrades to address a lot of macs. Starting with the mirror doors motherboards were frequently changed and as an engineer at Giga Design told me, they were pretty fast to begin with. So to answer your question, yes, in general single processor macs should be able to take a dual processor upgrade. If you purchase one of the older cpu upgrades it may be that they were intended for Quicksilvers that were dual to start with but most of the newer upgrades have overcome that issue.
But, and I'm going to make an assumption here, you don't impress me as a tinkerer on computers. By that I mean, getting a medium speed upgrade, use it for a few months, sell it for a faster card for a few months, sell that one, get a dual, etc.. I would get a fairly fast upgrade (say 1gz. or so) get used to X and save your money for a newer mac. It will have built in everything, faster bus (which you can't upgrade), faster memory, etc.
I started out using X on an old 9600 with a single g4 450 upgrade card. It worked fine through 10.2. The gui of X is a processor hog so resizing windows, opening a folder, and new windows was slow but it did Photoshop filters was just as fast in X as it was in 9. It just felt slow. I have had my dual 867 for 2 years and could sell it for 2/3 of what I paid for it.
Go middle of the road on the upgrades (which is cheaper), and when it is unbearably slow, get a newer mac. That's what I would do.

I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

Things to note:
I have been unable to update firmware on this computer for about a year now. Im not sure why.
I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
any thoughts on the matter would be greatly appreciated, thank you.

Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

Why can't I download 10.4 for my G4 Dual Processor?

I have an older G4 500 mHz Dual Processor Mac and two other macs (iMac & new MacBook Pro). I just purchased Adobe CreativeSuites3 and realized I can't install on my oldest Mac without upgrading the System software. I want to have the same version of CS on all Macs. I looked into upgrading to Leopard and discovered it won't work with my G4. So I went to upgrade from 10.3.9 to 10.4 and it appears that Apple will no longer sell a new version of 10.4! Am I looking in the wrong place? Will my G4 successfully run 10.4? How do I purchase a copy of it?

Tiger is available at many online retailers. Price Grabber has several listed. Make sure to get the full retail version.
Personally, I would stay away from E-Bay. A lot of machine specific versions get sold there, and unless you know what you are looking for, you'll end up with a disk that doesn't even work on your Mac.

CHUD on a dual processor MDD running Leopard (10.5.8)

I finally got around to installing CHUD today and am wondering if some of you folks who have used it for a while might have some easy answers to a few questions.
I first tried version 3.5.2. It installed, but I couldn't adjust any of the settings. I then read on japamac's site that some MDD's could use 4.4.4. I installed that version and it does work (In fact, I'm posting this with one processor tied behind my back). However, there does not seem to be an option for nap mode.
Also, after I toggle between single an dual processor mode a few times, performance in dual mode seems to take a big hit. A restart solves the problem, but I'm wondering if this is normal.
Is there any way to get nap mode to work in a dual cpu MDD running 10.5.8?
Is there any way to get it to stay in single CPU mode when it wakes from sleep?
I read through the discussions at xlr8yourmac before posting this. It appears that some people have been able to get nap mode to work under Leopard, but they are not always careful to mention exactly which version of Leopard and CHUD they are using.

Hi-
When installing CHUD, it is also necessary to run CHUD remover to deinstall previous installations.
If not deinstalled, odd stuff happens.
3.5.2 is the one for dual processors.
Other versions have mixed dual processor support.
This is one of the claims that 4.4.4 works, but I have lingering doubts
http://discussions.apple.com/thread.jspa?messageID=5974655&#5974655
I may need to edit my blog page.....
It takes a script for automatic Nap enabling in a dual processor machine with 3.5.2.

Dual processor not showing up in Activity Monitor

I have a dual processor G5 PowerPC at work and when I look at the CPU Activity Monitor it shows me the activity on both processors. My Mac Pro at home is also a dual processor but when I look at the activity monitor it only shows one processor thread. Is this normal or is there something wrong with my Mac Pro? Anyone else notice this as well?

Hi KSStudio. A few questions to clarify.
1. Is this a dual or single cpu machine?
2. How many cores per machine?
Check it out...
Assuming you have a dual cpu (8 core) 2009 mac pro, when you use activity monitor choose > Window > CPU Usage. You should see a floating window with 16 panes. (8 panes if you have a single processor/4 core model) Under normal loads using 10.5 you should see some activity in all 16 panes. Under normal loads using 10.6 you should see activity in odd numbered panes. You will see activity in even numbered panes when the load is high. This is normal and due to Snow Leopard's improved utilization of processor technology.
Hope this helps.

Mac Mini Dual Processor?

I was told by a salesman at the guitar center that I could hook my mac mini G4 to a powermac G5 to boost the speed a bit. I don't really know how I'd do that, but my question is, if that's possible could I hook up a Mac MIni G4 to another one of the same speed and make that a dual processor set up...??
Mac Mini Mac OS X (10.3.9)

To my knowledge, there is (unfortunately) nothing as simple as that.
Still It should be "doable" to connect two macs to share their capabilities, but, due to the power used to run the process, you certainly won't end up with the power and ease of use of a dual processor machine...

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.

Dual core 2.3 or dual processor 2.5 for FCP Studio 5?

I'm on the fence whether to buy a dual core 2.3 with a 7800GT card or a refurbished dual processor 2.5 with a x800 card. The saleman today was pushing the 2.5 b/c he said it was faster, though he said the x800 would run around 20% slower than the 7800GT. I had actually read that if anything the dual core 2.3 was faster. I've been looking all around (including barefeats.com) but can't seem to find much to confirm the graphics card statement. Thought I had read in a post here that they were also about the same speed. Is he right about this?
Untimately, I'm looking for something to run FCP 5 Studio and things like Boris Red and Combustion with. With the price difference being about $380 b/t the two options, which one would be faster and the better bet?
Thanks ahead of time for any help!

FCP doesn't care about your card. Much. Not now anyway, we have no idea what will happen in the next rev but the trend is toward offloading much of the work to the OS and GPU.
Buy what you can afford and buy what you think you need to make money now. You can always upgrade in 18 months when the second generation of the Intel machines are likely to be shipping.
Are you using Motion or Aperture? Different criteria. Dunno 'bout no Combustion, never been using it.
