Quad Core - Dual CPU's

Does all G5 Quad Core (Dual CPU's) support all MAC OS and all MAC software?
For example, could I run MAC OS 10.x and Final Cut Studio on a Quad Core MAC without any configuration or problems?
Dave

Hi Dave;
I can vouch for what the Innovator says about running with a lower version of OS X. When I migrated from my PM G5 MDD to my Quad, I had forgotten to upgrade my maintenance disk to 10.4.3. I tried toboot from it on Sunday. The maintenance disk was at 10.4.2 so I thought that should be close enough. WRONG! The reboot failled big time. I had to down the 10.4.3 upgrade and apply it to that disk before it would boot.

UPGRADING AND MIXING MEMORY ON MY MAC PRO QUAD CORE DUAL 2.8 (Xeon)?

Hello,
I have a Mac Pro Quad Core Dual 2.8GHz (Xeons) with 4GB of memory (2 x 1GB Apple modules + 2 x 1GB other brand - Shown as "Manufacturer 0x855D") and now I want to fill the other 4 memory slots by adding an additional 16GB (4 x 4GB modules) for a total of 20GB of RAM.
My 2 questions are:
1.- In which order/pattern should I install these new 4 X 4GB modules along with my original Apple 2 x 1GB modules and the "Manufacturer 0x855D" 2 x 1GB modules the best way (for better performance)? - I have heard stories that if I do it improperly, I could slow down my Mac Pro...
This is how I have them configured right now:
Raiser A / DIMM 1 = 1GB (Manufaturer "0x830B") - I assume this is the Apple memory, right?
Raiser A / DIMM 2 = 1GB (Manufaturer "0x830B")
Raiser A / DIMM 3 = Empty
Raiser A / DIMM 4 = Empty
Raiser B / DIMM 1 = 1GB (Manufacturer "0x855D") - How can I find which manufacturer is this?
Raiser B / DIMM 2 = 1GB (Manufacturer "0x855D")
Raiser B / DIMM 3 = Empty
Raiser B / DIMM 4 = Empty
2.- What brand would be most compatible to work with my Apple 2GB (2 x 1GB) factory memory? Kingston? Crucial? Mushkin? iRam? Corsair? OWC? (Does OWC sell their own brand? or which one do they carry?-its not specified on their web)
Thank you so much in advance for all your help!

About RAM installation in the Mac Pro
Mac Pro memory arrangement photos
Mac Pro Memory Configuration
Memory Tests- "2008" Mac Pro
Ram should be installed minimally in matched pairs and optimally in matched quads. This means the memory modules are the same size and specifications. They should also be equipped with the Apple-certified style of heat sink.
Brand really doesn't mean much as long as they work.

Error message on my Mac Pro Quad Core Dual

Hello..I'm hoping someone out there can help or advise me.
I turned on my mac this morning to find it's normal loading screen of grey with the darker grey logo in centre..all normal at this stage. This was followed by a wipe from top to bottom making the background grey a little darker and in the centre the apple logo was replaced by what appeared to be a semi transparent power button symbol with the words. "You need to restart your computer. Hold down the Power button for several seconds or press the restart button"
I have tried this several times to no avail I have also zapped the P RAM again nothing. Can anyone out there help. I have a Mac Pro Quad Core Dual which is only a few months old and is up to date with its system software.
I could be so grateful of any assistance.
Warm regards

Make an appointment. But in the meantime...
So from cold boot, you can't do the Command Option P R through 2-3 full reboot cycles (don't let up)?
Unplug everything and let it sit overnight without power cord or anything. That is the only way to rest the SMC system management controller on the 2008 model, the older model still had a reset button.
Also learned that the 2008 Macs can all boot AHT if the original OEM installer was used to install the system and the drive has not be completely reformatted and retail OS X used, just holding down "D" on startup. But you have to
Also, pull all your hard drives. Rule out that, which I have seen a hard drive cause panic on startup, which required disabling journaling and other repairs from Disk Utility and deleting caches, then repair, and finally do Safe Boot (shift key down on startup).
The only way to test RAM is with TechTool Deluxe or Pro; with Memtest or Rember; and to test some devices is to try using a differnent one, keyboard and mouse included if you have any.
Last hope: open case, look inside, take the two RAM Riser cards and pull out, check the DIMMs are fully seated.
If you have 3rd party memory, remove that (would need to before taking in probably).
Might want to put RAM back to way it shipped with 2 x 1GB and one DIMM on each Riser in slot one. Maybe that will wake this sleeping giant. Changing RAM config use to be one way to clear nvram in the distant past in the time of Arthur.
PS: it is "odd" to find a BTO 3.2GHz system, and only 2GB. For memory performance, Barefeats found a marked improvement with 8 DIMMs, and of course Mac Pro really needs memory to feed 8 cores and pro apps (2GB would be okay for web and email type use only).

Quad-Core/Dual-Core Front firewire issue with VX2100 camcorder

Hi,
My VX2100 camcorder will not work (isn't recognized) by the front firewire port on my quad-core G5. The camcorder works on the back port, and I have tried this at the apple store on other machines, all with the same result. Has anyone else had this issue or can offer some advice? Other firewire devices and camcorder have worked fine (I have a canon one that works with the front).

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

This is cute but will it support the Quad Core single cpu Core 2 Extreme ??

Any idea if the 2006 Q4 Quad Core 2 extreme will be supported.
http://www.reghardware.co.uk/2006/08/17/intelextreme_roadmap_aug06/
Also is there a way of getting drivers for the 7900gtx / G71/G72 or better to run on MAC PRO as my Dell's E1705 has 7800gtx and the other E1705 has 7900gtx 512mb and I need a bit more power ???
Will the power supply handle 2 /4 7950 gx2 ???
http://www.nvidia.com/page/geforce_7950.html
I am NOT much interested in the G70 / 7800gtx / fx4500 quadro as my old laptop has that in it already.
Any help will be nice.

No… the Core 2 Extreme Edition is based on the Conroe processor, rather than the Woodcrest, which does not support 1.33GHz bus nor multiple processor configurations.

PCIE, PCI, and the quad-core

I have recenty bought the new Quad-Core, a machine that I am very happy with. However, there is one aspect about it that I am not completely clear about. I understand that the PCIe and PCI cards are not interchangeable. Does the quad-core not have a standard PCI slot? In other words, for any video capture cards or other upgrades, I can only use PCIe, correct?

Well, I'm glad it is cutting edge, but the costs definitely hurt. I'm looking at $589 for a video capture card and monitoring system. PCI is as little as $300. Oh well!
Thanks for your input, I appreciate it!

ATSServer CPU @ 200% LOCKS-UP Mac Pro dual quad-core desktop

My dual quad core running Mac OS X 10.5.5 locks-up frequently at boot.
Required hard (destructive) reboot, until I figured out workaround
described below. Apple really needs to fix this as a high priority.
Symptom: Desktop freezes and the system becomes unusable.
Usually occurs when booting the system, but can happen
at other times spontaneously.
When it occurs during boot (after desktop first appears, usually
as task bar is starting to populate), the wedging is so bad that
applications are effectively 'suspended' mid-launch.
Icons and menu and mouse buttons and keyboard completely unresponsive.
Usually just a spinning beach ball that tracks with the mouse is present.
Attempts to resolve (both failed):
1. Did a fresh install of Mac OS X (with data transfer) and upgraded,
which brought system to 10.5.5. (Problem appeared immediately
on fresh installed system).
2. Totally re-indexed Spotlight and de-selected option to not index
PDF documents.
Workaround:
1. Enable 'ssh' logins and root user.
2. Login via 'ssh' from remote system, while Mac Pro desktop frozen.
3. Become super user in 'ssh' session.
4. Find ATSServer with 'ps -ef' or 'top' command.
5. Terminate ATSServer with 'kill -9'
6. Desktop on Mac Pro immediately unwedges and applications
that hung during start-up finish launching.
/var/log/system.log (many messages like this):
System/Library/Frameworks/ApplicationServices.framework/Frameworks/ATS.framework /Support/ATSServer[241]: FOExceptionMainHandler caught a fatal exception at 0x96028036
Safari[151]: GCGetStrikeMetrics failed: error 5.
Plea from customer:
Apple: PLEASE post an update to fix this very soon.
If anyone has clear instructions on what I can do to fix properly until
Apple comes up with a real fix, for example, caches to clear,
how to identify a faulty file, or quarantine a faulty faunt,
or any other diagnostics, please feel free to reply.
My machine was already in the shop for five weeks recently for repair,
and I can't afford down time, because I'm mid-project right now,
and it will be a HUGE setback to have to bring my machine into the
shop again for another 'n' days.

I'm also seeing this problem on my MacBook with 10.5.5. After killing ATSServer via ssh, I looked in the Console, and found these console messages which occurred when the GUI locked up:
10/18/08 12:44:03 PM com.apple.ATSServer[2554] Notice ATSServer(2554,0xa076afa0) malloc: * error for object 0x83ac00: incorrect checksum for freed object - object was probably modified after being freed.
10/18/08 12:44:03 PM com.apple.ATSServer[2554] Notice * set a breakpoint in mallocerrorbreak to debug
The problem seems to happen whenever I mount a certain remote shared volume (AppleShare) from my old desktop computer (G4 Dual 450 running 10.4.11). I guess it could be that ATSServer is choking when trying to generate QuickLook previews for some document on the shared volume...

Is the mac mini server the same hardware as the other mac minis (except for the quad core i7 and dual hard drives) with different software or is it configured differently?

I have a mac mini with an i7 dual core processor. It is perceptably slower than my macbook pro with a quad core i7. Does the mac mini server have the same hardware configuation as the regular mac mini with server software or is the hardware different (aside from the i7 quad core and dual hard drives)? I want a mini with a quad core i7...

Your assumption is correct. The server does however only
have the Intel HD3000 graphics like the base model with
no option, at this time, for the discrete graphics chip. So,
depending on what you are using it for, that could be a deal
breaker. Remember that your MBP does have a discrete
graphics chip.
I have a 2011 Mini Server connected to a Thunderbolt display
that gets used as an engineering workstation and general
personal use (some photo editing, LP restoraton, general
internet browsing). You simply just not enable any of the
server services. I find the combination to work quite well
for my purposes. I also have a 13" 2.7 GHz i7 Macbook Pro
which is pretty much strictly for work. As far as CPU
power it is pretty much equivelent to your Mini. For the most
part I find the Mini does outperfom my MBP. I heavily use
Parallels and Windows7 virtual machines, so the more cores
the better.
So, If you do a lot of CPU intensive stuff that is multithreaded,
the Server may help. If it is graphics intensive and your software
heavily leaverages the GPU, you may actually take a hit on
performance.

Mac mini (Late 2012): Dual- or Quad-Core?

I'm upgrading from a MacBook (2006) and - as a frequent iPad user - am thinking of just getting a Mac mini. I'm not sure though as wether to get the i5 dual-core or i7 quad-core version.
What I'll be using it for (none of these on a professional level, prosumer at most ;)):
Photo editing (iPhoto, thinking of switching to Aperture)
Web development (Coda, Espresso, local test server)
Designing (Sketch 2)
Full-HD video editing
Web, office, social media, ...
Can I expect a signifcant performance boost at these tasks from the quad-core model or will the differences be barely noticable (also considering most of these applications will be running simultaneously)?
I'll be maxing out RAM from a third party vendor in both cases, HDD capacity is not important and I'm not going to upgrade to SSD or Fusion Drive.
What do you think? Any thoughts appreciated!

Thanks for your insights! My inital goal was being cost-efficient; Fusion Drive is only an option on the quad-core model thus making it 1080 Euros were I live. That's almost an entire new Mac mini which I could buy in 2-3 years. I don't mind CPU intensive tasks taking longer (e.g. rendering final movie) as long as the actual "creative process" runs smoothly (e.g. cutting the movie).
As you both said finding out how/if apps take advantage of multiple cores is not that easy. I guess I'll have a closer look at all the benchmark tests and reviews that will be showing up in the coming weeks.
I think Fusion Drive on a dual-core might boost performance more than just going quad-core, unfortunately this is not an option for the lower end model. Also I want to wait a little to see if Fusion Drive is proprietary Apple hardware or just implemented software-wise (which would mean I could fix a broken drive myself after warranty has expired).
By the way, any guesses on Black Friday sale options (as far as I could find out the Mac mini wasn't included last year)?

Macbook pro, dual core or quad core?

Hey guys Im getting an early college present and was wondering which Macbook I should look at. This will be my one and only computer while im in college. No photo editing or anything like that, maybe some video editing but it will be almost none. Will be used to surf the web and write documents. My question is should i get the dual core or quad core processor? Will it really matter for what i want it for? One thing I absolutely hate is lag! So the faster of the two the better.

So if I went with the quadcore because you guys say it is faster than the 2.9 ghz dualcore. Would the difference be noticable between the 2.6 ghz and the 2.3 ghz? I noticed the 2.6 has 8 gb to the 4gb and 750gb to the 500 gb.
Well, actually, only one guy said the quad core would be faster, but it is not clear why they said that. You said you were only going to use it "to surf the web and write documents." Well, guess what. You don't need a quad-core for that. You don't need a dual-core for that. I've surfed the web and written documents on my old single-core iPhone. Those tasks are just not that demanding.
So unless there are more things you want to do that you haven't mentioned, there is just about no way it's worth paying for quad-core or a 2.6GHz processor if all you are going to do is surf the web and write documents.
The quad-core is going to speed up operations that specifically benefit from parallel processing, like intensive editing of photo/audio/video, or bulk encoding of audio and video, or specific math apps, stuff like that. And most Mac users would not benefit from choosing the 2.6GHz over the 2.3GHz because the performance of so many common uses depends not only on the CPU speed, but actually on the overall balance of CPU, RAM, and disc. In other words, if you really have a legitimate application for 2.6GHz it usually means you must also install a great deal more RAM and also an SSD to avoid creating a bottleneck that holds back the CPU. But then you would have a machine that is massively overpowered and overpriced for surfing the web and writing documents.
You could surf the web and write documents quite effectively on the least expensive MacBook that Apple sells. But since you do want to keep it throughout all of college, it is a good idea to buy something higher than the bottom of the line. For a Mac for very basic uses that should last four years, I would suggest:
13-inch MacBook Air with 256GB SSD storage and 8GB RAM
13-inch MacBook Pro with 500GB HD storage and 8GB RAM
13-inch MacBook Pro with Retina Display with 256GB SSD storage and 8GB RAM
(You didn't mention what your budget is)
I suggested 13-inch because it's more portable than the 15-inch but more comfortable for 4 years than an 11-inch. I chose storage sizes that would be appropriate since you said you would do some video. And I chose 8GB RAM because 4GB may not be enough for 4 years, and also because insufficient RAM is often a bigger cause of lag than CPU or disk speed.
If you have a limited amount of money, from this point on you'll need to justify why you would want a bigger screen, a faster CPU, or more cores given the two tasks you said you'd be doing most of the time. Because again, if you didn't actually need a Mac, you could write documents and surf the web on an iPad with the Logitech Ultrathin Keyboard Cover and be done for $600.

Dual-core or Quad-core for Premiere, After Effects, and Photoshop CS4?

We are planning to purchase around 25 computers for a computer lab for working with CS4 Production Premium at the high school level. Mainly Premiere Pro, After Effects, and Photoshop. Our budget is, unfortunately, a mere $550-$625 per machine (just the tower though, we have monitors). I've already established that a 64-bit operating system makes a significant difference in the performance, even though Photoshop is the only 64-bit application, and I'm now hung up on whether or not it's worth the cost of a quad-core processor over a dual-core.
I'm discovering the different hardware needs for each application, so I'm trying to find an economic balance that will give me the best performance per buck. It seems that Premiere benefits significantly from more cores (we're editing 1440x1080 AVCHD), and this article over at Tom's Hardware has convinced me that I don't want to compromise with a hyperthreaded dual-core for After Effects.
I'm also struggling with what part the graphics card plays in the mix. Which applications lean on the graphics card, and will it make much difference as long as I meet the requirements (OpenGL 2.0, Shader Model 3.0, Direct3D 10, and 256 Mb Ram)?
I understand I will need to settle for less-than-awesome with my budget, but I'm already making sacrifices to get the number to $625. I would like to make sure that those sacrifices will be worth it for a quad-core system.

I think I may have answered my own question by looking at these charts over at Tom's Hardware:
http://www.tomshardware.com/charts/2009-desktop-cpu-charts-update-1/Adobe-Premiere-Pro-CS4 ,1404.html
http://www.tomshardware.com/charts/2009-desktop-cpu-charts-update-1/Adobe-Photoshop-CS-4,1 387.html
http://www.tomshardware.com/charts/desktop-cpu-charts-2010/Video-Editing-Adobe-After-Effec ts-CS5,2427.html
I think that the jump to the quad core in Premiere Pro is worth it, even if I don't see as large of an improvement in Photoshop or After Effects. I am still interested in the role of the graphics card in the mix if anyone can shed some light on that. Will an integrated graphics card (like an Intel GMA x4500 or Radeon HD4200) suffice or will I need an actual graphics card to realize the benefits?
Thanks

Mac Mini dual core or Mac Mini quad core server for normal use ?

Hello
I am looking to replace my desktop work computer from my 2011 i7 quad core 2.0 MBP for a Mac Mini because it was actually made for desktop use and my minidisplayport - dvi adaptor just broke ( I think because to many unplugs and plugs from the laptop to the monitor ) .
I work in Photoshop, Dreamweaver, Aptana, Netbeans, open 20 + tabs in chrome, firefox so I need a bit of performance
I have no use for Mac OSX Server, I just want to be at least as fast as my MBP. I can see that the 999$ Mac mini has the same processor as my MBP ( 2.0GHz quad-core Intel Core i7 ) but no dedicated video card. Also, the 800$ Mac mini has a video card BUT just a dual core - 2.5GHz dual-core Intel Core i5 .
What do you think I should get ? I don't play games, I have windows for that anyway. Would the dedicated video card make much of a difference ? ( does photoshop or mac use it much - openCL etc. )
Thanks!

You might also consider the Apple only available Mini
which has a 2.7 GHz i7 dual core which has dedicated
graphics. Also, all the 2011 i7 processors (Sandy Bridge)
are hyperthreading.
As for dedicated graphics, they are really only needed
for high end gaming or 3D rendering apps. It will
make no difference with the software that you mention,
as they are more CPU intensive.

Quad core or dual core i3

i dont know which computer to chose. should it be quad core with 2.5 ghz or dual core i3 with 3.2 ghz?

There is so much more beyond just the CPU too - such as graphics chipset. Again, it all depends on the usage scenarios. Some workloads don't parallelize well, so work better on a higher-clocked but lower core count CPU. Others parallelize well and are better on a quad-core.
*disclaimer* I am not now, nor have I ever been, an employee of Best Buy, Geek Squad, nor of any of their affiliate, parent, or subsidiary companies.

Can a logic user benefit more from having a Quad core as apposed to a dual

My friend is thinking about updating to a Quad core from a dual core 3.0 ghz. He uses logic as his main sequnecer and was wondering if it would be a big performance step up to do it

Hardly. It shows that in general performance a Mac gets about 1.4 times faster with every doubling of the number of processors. So a dualcore is 1.4 times faster than a single, a quad is twice as fast as a single and an octo (dual quad) is twice as fast as a dual and 2.8 times faster than a single core - given that CPU- and bus speeds are the same... get it? It's a quadratic scale (it seems)
The fastest Mac today (I believe) is is the Mac Pro 3.2, with two quadcore Intel Xeon 5400 'Harpertown" processors. Geekbench clocks it at 8499. My machine (G4 dual 1.25, the 'minimum machine' for LP8) scores 1044... but I manage...
