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...

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.

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.

2009 Mac Pro 8-core shut off randomly, won't restart. Swapped processor board and HDD's into my other tower. Started fine and worked for about 10 minutes, then same thing. Powered off by itself and won't restart.

Both towers are 2009 models, one is 8-core, the other 4. I figured the problem was with the power supply, so I just stuck the guts from the 8-core into the 4-core. It booted up with no issues at all, didn't require any updates or anything. Firefox even restored my tabs. But after about 5-10 minutes, the machine shut off at random and won't start back up. The DIAG LED lights up one LED yellow when pressed, labelled "5V STBY". Same LED on both boards.
Any ideas? I've got two really expensive paper weights at the moment, and my AppleCare plan expired 3 months ago.

Dust VAC for dust bunnies
real issue can be thermal paste or lack or needing redone
dust clings to any ram or electronics or inside psu and graphic cards
motherboards both support dual processor?
thermal sensor readings from Hardware Monitor would be nice
unplugged is not enough to reset the SMC, power on button also, and every cableetc disconnected
try with one dimm too

HELP! Dual processors not seen. What happened to them?

I have a twofold problem, both on AGP Graphics machines with the Sawtooth boards. I purchased mine used about a year ago and it came with a dual 550 processor upgrade installed. It works great, but somewhere recently, maybe after my latest upgrade (10.4.8) I checked my system profiler and it now shows the processors as dual 500s. It used to say dual 550. Any idea where the other 50s went? Could this be a glitch in the OS that doesn't allow it to see the the extra gHz? I may try zapping the PRAM, but do you think it's because of the software? I'm baffled. The other part of my problem is I just upgraded the other AGP machine with a dual 500 from a gigabit ethernet unit. It showed up fine as a dual 500 in the profiler. Then I swapped in a 160 gig internal and popped the OS on it and relegated the smaller, second internal into a storage drive, erasing the OS on that one. After doing that, it just shows up in the profiler as a single 500. Weird. I've never heard of a dual processor losing half and still work fine on the other. As I said before, it was showing up fine until I installed Tiger on the new drive, transfered the info from the previous system via the installer, and now, only one processor shows. Any ideas or suggestions for both machines? Particularly the one missing the entire half of the processor? Thanks!
G4 Dual 550 Mac OS X (10.4.8) 1.2 GB RAM, 380 GB Storage, DVD Burner/Handy Slide-Out Cup Holder, USB2, TV Tune

I am having the same problem. I have a 160GB drive I've been using for years with 10.3 installed. Took that one out and started fresh with 2 160GB drives (one WD and one Maxtor, both 8GB cache)and set them up as "concatenated" RAID set in Disk Utility (while booted from Tiger disc). Installed Tiger, only shows ONE 450mhz processor in Activity Monitor and System Profiler. And it's definitely only running one processor because my Mac is running VERY slow. I went back to the original 160GB drive running 10.3x and everything is fine, 2 450mhz processors showing and fast as ever.
I've been searching apple support, google and the like but no answers. PLEASE HELP!!!
Thanks, Eric

Dual Processor Mac Mini

Now that the new Mac Minis have a dual processor, will this be a good option to run FCP? My G-5 generates SO much heat I have to move it out of my home office before I start editing!
I was hoping the new Mac Mini might be my salvation.
Any input??
Thanks.

G5 Dual 2 GHz PowerPC Mac OS X (10.4.7)

But you can capture (DV and native HDV) to a USB 2.0 external drive instead (if your camera interferes with the firewire drive, or visa-versa), and if you have a dual interface external drive, once you have finished capturing, you can re-mount it over firewire and continue from there.
An iMac would be okay, full size HD, some real graphics card options (quite decent ones on the new 24"), the single FW interface becomes the only sticking point for FCP. I use a mac mini to encode and render very long jobs, because I can leave it on for months on end, quietly getting on with the job. My Powerbook G4 also has a single firewire bus, and I can manage okay with it, but I don't do anything too big.
I think you could edit DV on a dual core Mini fine, and HDV at a pinch. Motion would be very difficult, if not impossible, because of the lack of a graphics card.
You will need the latest 5.1 version of Final Cut Pro - see this page for upgrade / crossgrade information:
http://www.apple.com/universal/crossgrade
A lot of the posters here are only interested in the latest and greatest hardware, but the basics of the job (online DV editing) have not changed in nearly a decade now. Consumer level computing has changed a great deal, Apples consumer offering has changed enormously in the last 12 months.
Having said all that though, I would still agree with the general 'mood' of the board on this one, stick with your G5, maybe re-position it to affect you less (somehow), the G5 is a better / as good as machine, and, more importantly, you already have one.

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

Getting the cover off the heatsink, dual processor

My Power Mac G5 (dual processor) recently had some internal burning/fire/smoke issues inside the big cpu/heatsink box, and all I want to do is to take this apart and see what burned, but I can't get the **** thing off! The big box with the two G5 logos on it is being very uncooperative... There are no resources online for getting this thing open. There's a plastic thing at the left end that seems like it wants to come off, and the fans at the other end are slightly mobile. Please help!

I just went through the take-apart exercise to get to my processors. When looking at the processors, on the upper right side, there is a small piece of gray plastic that looks like a tiny circle on the aluminum wall between the processors and the graphics card/PCI slot area. This is a pin that holds the cover in place. I had to destroy that tiny piece of plastic by first sliding some iPod-opening tools to get a start, then some really thin screwdrivers to pry is some more, then a little fiddling to get some wire cutters in to grasp it and pull it out. Once removed, the cover slides towards the front of the computer and out, then you'll see the 4 metal pins which hold the cover in place.
But once I got that off, the next challenge was getting to all of the screws holding the processors down. You will need a long magnetic driver and the right sized torx and hex bits. I was able to pull every screw out and surgically remove them all with chopsticks and various other tools. But even then, when I pulled at the processors, they would come up about 2-3mm, then appear to be stuck. I eventually gave up and put everything back together. I'm guessing I need a new power supply, but I'd hate to replace that and discover I need a new logic board or processors. Alas, this Mac appears to be very difficult to take apart.
My advice to you is to not bother and just wait for the new product announcements at MacWorld before purchasing a replacement. I'm hoping that the Mini and/or iMac update has external eSATA so I can attach large 1TB hard drives at full bus speeds.

Can I put a dual processor in my power mac g5 which only has one processor right now

Can I put a g5 dual processor into my power mac g5? I have a power mac G5 but it only has one processor so I wanted to upgrade to the G5 dual processor found in the later version power macs. Would I be able to do this? If i could do this would i need another fan or other parts? I was also thinking of putting more ram in and another hard drive. PLEASE HELP

Exactly what to do with ram and video is hard to say without the model details. You can go to http://www.everymac.com and click on Power Mac G5 and then find the machine you have. The detailed info on the machine will show how much and what type of ram you can put in (I always use ram from either OWC, http://www.macsales.com or Crucial, http://www.crucial.com) and also gives the installed video card info. OWC would also be a good source to see what video cards are available that will work with that logic board.

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.
See this thread:

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.
