Dual 1.8 G5 Losing Processor

I have a Dual 1.8 G5 (2003) that I recently loaded Leopard on. A few times this week I've had the second processor disappear. MenuMeters and Activity Monitor will show the CPU at 0% regardless of load, and when I check the System Profiler it only reports a single CPU. The second processor returns if I reboot the machine, but this is still very strange and rather unnerving behaviour. Anybody have a clue what's up?

Hi.
I'm having similar problems with my Dual 1.8. Except mine boots with two CPU's showing...then, anything from 5 to 30 min, the machine freezes or kernel panics.
A force shut down later and back in the OS, only one CPU showing. The Apple tech guys here in Cape Town say its cpu or logic board...I hope it isn't the latter as it has been a year since the last logic board got replaced.
There is not more to say that we are the unlucky few. Although there seem many Dual G5's in the workshop with similar problems here.
I hope for our sakes its just CPU because its cheaper and the faulty one can be deactivated until the cash rolls in.

Dual 1.8 G5 Losing Processor Since Leopard

I have a Dual 1.8 G5 (2003) that I recently loaded Leopard on. A few times since I've loaded Leopard I've had the second processor disappear. MenuMeters and Activity Monitor will show the CPU at 0% regardless of load, and when I check the System Profiler it only reports a single CPU. The second processor returns if I reboot the machine, but this is still very strange and rather unnerving behaviour. Another user reported a similar issue in the G5 forum, also tying it to Leopard so that's why I'm reposting here. Is this happening for any other models? Does anybody have a clue what's up?

Hi Rob,
This is a stretch, but try resetting the PRAM:

Dual Core with 2 different processors in a Satellite A100-599!!??

Hello,
My Satellite A100-599 is a Core 2 Duo T7100 2.00 GHZ.
In Device Manager, under Processors, I have 2 processors:
Intel(R) Core(TM) 2 CPU T5500 @ 1.66GHZ
Intel(R) Core(TM) 2 CPU T7200 @ 2.00GHZ
Is this normal? Shouldn't I have two T7200 processers @ 2.00GHZ ?
Thank You.

Hi mate,
no, its impossible that a dual core CPU has two different cores. I think its rather a software bug which displays the model not correctly. To fix this there is some bugfix from microsoft which should be availble on the microsoft website.
You can also try to update your chipset drivers from the www.intel.com website.
But physically its impossible because the cores are on the same processor casing, so I dont think that intel would sell CPUs with different cores. :)

Buying a Power Mac G5 DP 1.8GHz Dual with a PPC 7450 Processor???

I just purchased but have not received as of yet a Power Mac G5 DP 1.8GHz Dual PCI-X 1 GB 160 GB. In the Details it is stated: "1.8 GHz DP PPC 7450 (G5) x2 RISC Processor."
A friend of mine mentioned that the PPC 7450 is a G4 processor but it might have been used in what is referred to as a G 4.5 PPC. That the true G5 processor should be a 970 fx processor!
Can someone quickly confirm one way or the other. The machine might ship to me tomorrow (Monday) and I will tell them not to ship if I have been misled.
Thanks much for a quick response.

If it's a Power Mac G5, then the description that it's a PPC 7450 is wrong (a G4). G5's are 970.
Since it is hard to mistake a G5 for a G4 Power Mac, and G4's did not have 1.8 GHz processors (unless it has a third party G4 upgrade) or PCI-X, it is likely that you are getting a Power Mac G5.
I've never heard of a "G4.5" description. Apple sold G4 Power Macs up to 1.42 GHz in the curvy plastic case, and then sold G5 Power Macs in the squarish aluminum case. You can't put a "G5" PPC in a G4 Power Mac, and you can't put a "G4" PPC in a G5 Power Mac.
But it wouldn't hurt to contact the seller to verify that it's a Power Mac G5 (huge aluminum case).

What the heck is Single Core, Dual Core, and Quad Core Processor Configurat

I am listing an eMac computer on ebay. I have all the information necessary except processor configuration. Do eMacs come with Single, Dual, or Quad processor configurations? Or does it vary? I don't even know what those are really.

Make sure to follow these steps when selling*:
http://www.macmaps.com/selling.html
As was already indicated all eMacs were single core.
Apple didn't start releasing multicore machines until the later G5s.

Dual G5 2.5 missing processor.

I've been using a dual G5 2.5 for ages and I just realized lately that my dual G5 went from dual to single! While researching around the Internet, I saw that there are multiple instances about the liquid cooling leaking and killing machines.
Anyone dealt with this problem?
Many thanks.

Me and two friends use Macs for making music, I've had 4 iBooks, all off which had Logic Board failures. They were replaced until they were out of warranty. I've sent back countless iPods, and I believe this isn't the original PowerMac I bought, I can't remember why it went back cause I'd only just got it. But know this one's almost dead.
One friend, has always had iMacs, he's had similar problems with Logic boards and the Screens losing alignment.
Another friend a professional musician also had countless PowerMac problems, i think he's onto his 3rd.
All 3 of us of could just be unlucky, but I find that highly unlikely.
All the ice white plastic and brushed alluminium doesn't make it a Super-computer.
I'm slowly beginning to realise this!
Our consumer rights in Britain state any electrical appliance should last a reasonable amount of time, I don't call 3 yrs a reasonable amount of time for a £2000 computer.
Apple make a big point of being environmentally friendly these days... It would be a lot more environmentally friendly for me to be able to fix this powermac for a reasonable price (not £400-500) and have to spend more money disposing of this one and replacing it with the newest shiny model.

Dual G5 only using one processor in Logic 8

So...
Why does my Dual G5 only use one of the two processors in Logic 8? The one processor will go to max, stop the song from a cpu overload, yet the second processor never kicks in.
Please help! U_U
Thanks,
bp

it seems that the buffer settings on audio preferences are too small.
use this setting:
I/O Buffer Size: 512
Process Buffer Range: Large
Or... you are using some heavy third party Virtual Instrument that don't support Altivec on PPC processors.
(many software houses make good plugins that works fine on Intel processors but they forget to use Altivec implementation for PPC Mac side)

Dual-core 2.3GHz G5 processor Vs. Dual-processor 2.3GHz G5

I have just purchaced a DUAL PROCESSOR 2.3GHz G5 is there a difference with this to a DUAL-CORE ?
Apple sent me this and told me it was the same thing .
sent me RAM that doesn't fit .
so I call and they say they differ . that i need different Ram
or the newer G5 for an added cost of $500.00
is there a difference or are they milking me?
I feel as they should just send me the new one .

Hi TGX;
There are some significant differences between the Dual Core and the Dual Processor 2.3 GHz Powermacs. There is the difference in memory and there is also the difference of PCI Express in the Dual Core as opposed to to PCIx for the expansion slots in the Dual Processor. In addition the Dual Core has the 1 MB of cache for each processor which improves performance.
Personally, if it was my machine, I would send it back and request that they send what I had ordered.

How can I tell if I have an i7 dual core or quad core processor?

I just got my brand new (2011 refurbished) MacBook Pro yesterday and it is slow and choppy right out of the box. I checked the "About This Mac" screen and it says I have the "2.2 GHz Intel Core i7". It says nothing about "dual core" or "quad core". I thought I was buying a quad core, but now I'm starting to wonder exactly what I bought.
Does anyone have any insight on this?
Thanks,
Matt

You have a quad core.
Number of Cores: 4

How do I get OS X 10.6 pon my OS X 10.5.8 Power Mac with only a dual processor

how do I get OS X 10.6 on my OS X 10.5.8 Power Mac G5 with only a dual 2 GHz PowerPc G5 processor. I do not see how or where to buy 10.6. Am wondering if it won't download to a powerpc 10.5.8...any ideas how I can do it?

Hi, we're out of luck, it cannot run on G5s.
10.5.8 is as high as any G4/G5 can go.
10.6.x/Snow Leopard General requirements...
   * Mac computer with an Intel processor
    * 1GB of memory (I say 2GB at least)
    * 5GB of available disk space (I say 30GB at least)
    * DVD drive for installation
    * Some features require a compatible Internet service provider; fees may apply.
    * Some features require Apple’s MobileMe service; fees and terms apply.
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory, I say 6 GB
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading, I say 50 GB.
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

Jdeveloper dual core processor performance problem

I have a dual core 2.4 ghz processor and 2 gig of ram and Im running Jdevloper 9.0.5.2 and my performace is terrible. Other developers in the company have non-dual core processors and they can start up in debug mode using the Jdeveloper embedded oc4j our application in 10 seconds where it takes me 4 min!!!!! It is a struts,ejb web application. Is there anything I can do to help in debug mode??? cheers.

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,
Brian

POwerMac G5 Dual Core vs Dual Processor

Am thinking about upgrading my G4 computers and going to the G5 Powermac. More than likely a dual processor or dual core. What is the difference between the dual processor and dual core? Is there any difference between these re: efficiency and how they work overall?

A "dual processor" refers to two physically distinct and separate chips. A "dual-core" refers to 2 processors on a single chip, often sharing certain resources (eg cache, memory, etc).
As far as I know, the only dual processor G5 Apple currently offers, is the Quad, or 2 dual-cores. The 2 GHz & 2.3 GHz machines, have only a single chip with dual-cores (2 processors on each chip), to the best of my knowledge.
To the best of my knowledge, having separate chips is better whenever possible, than multiple-cores (processors) on a single chip, because multiple cores have to share resources.
However, if you can only have a single chip, multiple-cores (2 processors) are advantages. It won't double your productivity, but should give it least a 40-60% boost. This assumes that the specific software you are running, takes advantage of multiple cores. A lot of software does not take advantage of multiple cores, and having a multiple-core machine is a waste.

After Effects and a dual processor

I just got a Dual 1.3Ghz Power logix processor and I wanted to know if Adobe after effects will take advantage of the second chip? I know the Final cut pro 5 will, and all the new apple compositing software(shake, motion, aswell as DVD studio) But will after effects get help from this or not?

If it helps, this page has benchmarks for G4 upgrades.
One of the benchmark options is "Adobe After Effects 6 Pro - Render 10 Frames".

Windows 2008 r2 guests blue screen on Windows 2012 R2 Hyper-V Cluster with e5 2670-v2 processors

Hello all,
We have a new hyper-v infrastructure deployed in two brand new Dell R720 Servers with 384GB of Memory and dual Intel e5 2670-v2 processors. This infrastructure is replacing an existing hyper-v 2008 R2 and all the guests are being migrated to this new cluster.
The issue we are seeing is our 2008 r2 guests blue screening ocasionally with 0x0000001a,0x0000004e or 0x00000050 bugchecks.
All this guests are configured with dynamic memory and with the integration components up to date. These same guests were running with no problems in the hyper-v 2008r2 cluster.
When searching i found this article from vmware that pretty much describes what we are facing:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2073791
Are you aware of the same problem with this kindd of hardware on windows 2012 r2 hyper-v?
Thanks!
Nuno Carvalho

Meanwhile i found this May 2014 update on the intel specification of the CPU we are using:
CA135 Incorrect Page Translation when EPT is enabled
Problem:
If EPT (Extended Page Tables) is enabled, then a complex sequence of internal processor events may result in unexpected page faults or use of incorrect page translations.
Implication:
Due to this erratum a guest may crash or experience unpredictable system behavior.
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
Status:
For the affected steppings, see the
Summary Tables of Changes.
This affects VMware as of the today update of the article i referenced in the first post, what about hyper-v?

Mac Pro 2009 Processor Upgrade Possibility?

I've searched and can not seem to find a straight answer. I have a 2009 Mac Pro with the single 2.66 quad-core processor. Since these Pro's use the daughter board (or whatever it's called) with the processor and RAM on them, can I just swap out that board with one from an official 2009 Mac Pro that has a dual 2.26 quad core processors effectively turning it into a 8-core machine? I'm not talking about tearing it down and swapping the actual processor, just pull the entire board out of a single proc machine and swap it with one from the same model year but with the dual proc machine. Anybody know if that would work?

Why would I consider selling and rebuying if the ENTIRE processor board with RAM and heat syncs and everything on it would simply plugin and work and I'd automatically have a dual processor setup? I'm still not sure anyone is fully understanding what I'm asking. Grant is the closest but I'm afraid of just trying it because I don't want to fry anything or break anything. If I knew it would simply work or not work, I'd just try it, but I don't want to ruin anything by trying. It's starting to sound like no one has ever tried this before. To me it seems like such a simple way to upgrade if it actually works. There would be no major disassembly, no processor swaps, no firmware upgrades, just a simple plug and play, but it sounds like no one can give me a straight answer. I'm just shocked no one has tried this. Anybody? Anybody swap the entire single-proc board for the dual-proc board?
Maybe pictures will help. Has anybody taken this out of their mac -
And then stuck this is and powered their machine up?
