Anyone running their iMac with 512 MB or one 1 GB or one with 1,5 GB RAM?

Please follow these instructions as I am curious on what your iMac will respond with.
I ran the test and it came no answer, but after removing part of the arguments i finally located this string in the result:
"reg" = <00000000000000400000000000000040>
This could obviously mean that I indeed have 2 64 bits wide registers working simultaneously. Can someone out there with "unmatched pair" run the test and report about the result?
Type this string at the terminal:
ioreg -p IODeviceTree -n memory -S
and look for the row:"+-o memory <class IOService>"
If this returns either "reg" = <00000000000000000000000000000040> or "reg" = <00000000000000400000000000000000> then I am on the right track to know if the system runs in dual channel mode.
Thanks in advance.

Of course I could just remove one of my 1 GB RAM modules, but I thought it would be much simpler if someone else meeting the criteria would be kind enough to share their results with me. The procedure doesn´t harm the computer. It would be a very stupid thing to post such a thing. Of course I´ll also mark the answers as helpful or solved when I have enough replies.

  • I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram.  Will I be able to run Lighroom 5 if I upgrade from Snow Leopard to Lion?

    I want to upgrade to Lightroom 5, but I'm concerned about compatibility with my 2008 intel Core 2 Duo iMac with only 4G of Ram.  Will I be able to run Lightroom 5 okay if I upgrade from Snow Leopard to Lion?  What will happen to the applications that aren't 64-bit compatible?  Also the Eye-one Display 2 colorimeter to calibrate the monitor will not run on Lion, so that will be an expensive upgrade to an i1DisplayPro. Is the upgrade important enough to offset the expense?  I have an Epson R2000 printer.  Will there be problems with the drivers if I upgrade to Lion?  It would be great to hear from other mac users who are also photographers and who print their own photos.

    I believe I have solved the problem.  I have 16mb ram so I went into photo

  • Anyone tested 24" iMac with FW800 drive?

    Just wondering if anyone has tried using a FW800 drive with the 24" iMac?
    I tried my Macally enclosure with a Samsung 250 GB drive. I found that the write speed was about 70% of the read speed (using Quickbench 2.1)---very similar to my old dual G5.
    I was hoping that they had fixed this probem. Guess not.

    Glorfindeal is correct. See the specs here:

  • Running Snow Leopard with 1 gig of RAM

    I'm very interested in upgrading from Leopard to Snow Leopard in the near future. However, I've seen a few people recommend a minimum of 2 gigs for installing SL (even though Apple only requires 1 gig). There are some testimonials that claim that 1 gig is fine for basic netbook work, but I regularly use the Adobe Creative Suite. It runs okay on Leopard (just takes a minute or two to get open), but I'm worried that more intensive functions will be totally unusable if I put SL on. This is seperate from the issues users have been reporting with CS4 on SL. I'm just curious if the upgrade will cause my valiant 1 gig to give up entirely and make CS4 and other apps too slow to use.

    Here's the thing - your 1GB RAM is the bare minimum required by Snow Leopard. It will run; but how well it will run is another matter. Your MB has been running ok so far, but you have already admitted that things are slow. Snow Leopard by itself is not going to cure overall system performance issues.
    The other thing you have to consider is the system HD. When it gets to about 50% full performance starts to degrade; this is a matter of simple physics. At about 80% full things usually start to get quirky. At 90% full you are getting close to crashing your system. This is because the operating system needs adequate space on the system HD to run, and among other things it uses that space to make up for any shortage of RAM; when it does that your system still runs but it runs more slowly because disk is not as fast as RAM.
    Then there's the matter that your MB is an old model with a slow bus & RAM speed compared to today's models.
    What can you do to improve overall performance? Add RAM. Upgrade the hard drive to a 7200rpm HD. Keep the HD under 50% full. Don't run multiple apps simultaneously if at all possible. Run a maintenance utility like MacOSXCocktail or Onyx from time to time. That will give you a noticeable jump in speed.

  • Anyone running Tiger & Retrospect with an iSight?

    I do support work for a user who has an iMac 800Mhz and an iSight camera. He also has a LaCie external (FireWire) hard drive and we use Retrospect 6 to do backups to file-based sets on that drive. Recently, we upgraded the station to Tiger (and did the corresponding Retrospect upgrade for 10.4 compatibility). Ever since then, the nightly backups get intermittent failures, reporting read errors (bad media) when trying to verify writes to the hard drive. I've bantered with LaCie tech support about this; they've had me update the firmware on the drive, and I even went so far as to reformat the hard drive (using Tiger's version of Disk Utility) but the problem keeps coming back. Even though the drive is under warranty, LaCie won't exchange it based upon only Retrospect having read errors. They've asked me to do all sorts of other testing, like attaching it to another computer, try another FireWire cable, copy large sets of files (1GB+) back-and-forth to the drive. It seemed like rigmarole to me.
    But I posted a question about this to the Dantz forum, and he says this problem happens to him -- but only if he's left his iSight also plugged into the iMac! We're not daisy-chained here; I have the LaCie drive in one port and the iSight in another -- but I'm wondering if anyone else out there can confim having this problem on their systems? If so, anyone know if it is supposed to be fixed in a future update?

    Hello CC and Paul.
    Welcome to Apple Discussions, CC.
    I am sorry to hear that you are having these problems. Most of us who upgraded from 10.3.9 (a mature OS X version) to Tiger 10.4 (the initial release of the version) immediately noted that all was not well. Try the good suggestions already posted in response to your problems. If they do not get you sorted, here follow my best ideas.
    As does everyone else, I expect that things will continue to improve as the updates are issued, but until then, the best I can offer is my suggestions for making the current version of Tiger work as well as I can. I also offer my work arounds for the remaining problems.
    First, I suggest that
    b everyone
    update to the latest version of the Mac OS they use. 10.3.9 and 10.4.2 both offer significant improvements over their predecessors. If you do not already have a well tried and good method of updating, see How I Update My Mac OS X.
    Then,
    b everyone
    should also try the
    b GREAT
    suggestions above regarding updating to the current firmware and software versions on
    b everything
    that is giving trouble. Apple covers Mac, the OS, Apple applications, and iSight with Software Updater. However, you will need to check and update all 3<small>rd</small> party hardware and software separately. Many 3<small>rd</small> party apps require updating for compatibility with new OS X version updates. Some patience may be required because development of the 3<small>rd</small> party updates can take a while. In the meantime, 3<small>rd</small> party questions that are not quickly resolved in Apple Discussions are likely best resolved in the 3<small>rd</small> party Support Pages or their dedicated discussions forums.
    I have no help to offer to those who must keep iSight, TV or other AV devices, external drives, and other Firewire devices all connected to their Macs all the time. As explained in the Possible hardware or software conflicts with iSight. FAQ, I use iSight by itself.
    iSight's demand for a solo connection to my Mac is not new to Tiger. It worked exactly the same for me in Panther, even in 10.3.9. I must
    b unplug.
    Nothing else works for me. See How to turn iSight (really) off.
    Those who have healthy Macs (Mac OS X maintenance), should not need a telephone to ask someone to connect iSight. iChat AV can run without iSight. In fact, I normally leave my iSight unplugged. A text or audio message asking to plug in iSight when convenient works for me. (You may need to reset the
    b iChat > Preferences... > Video > Microphone
    to "iSight Built-In" after you connect your iSight.)

  • Anyone running 2009 MP with SSD without TRIM?

    Does anyone have experience of running a SSD on a 2009 MP, without TRIM, without issues....if so for how long and which model?
    Thx

    OS X should by this time, but does not implement TRIM across the board, even though SSD has been around for 4 yrs and TRIM support in Windows has been supported since Windows 7 beta over 3 yrs ago. Is it only a matter of throwing a switch to support non-Apple ?  that seems to be what TRIM Enabler suggests. Not if Apple is using proprietary firmware.
    The SATA 3.1 specifications Queued Trim Command - allows SATA SSDs to execute Trim without impacting normal operation...
    http://www.sata-io.org/technology/6Gbdetails.asp
    Wikipedia SSD: "includes support for the TRIM command to reduce garbage collection for data which the operating system has already determined is no longer valid. Without support for TRIM, the SSD would be unaware of this data being invalid and would unnecessarily continue to rewrite it during garbage collection causing further wear on the SSD."

    I've seen Crucial m4 be loved and no love lost. Systems vary like people it seems.
    Top tier and Apple uses Samsung and is highly rated so I would have no trouble recommending them

    I have half a dozen Corsair, none with firmware bugs all are older SATA2 models.
    The newest looks or sounds good and 180GB is a good value size

    MacRumors post: one of the best tutorials on SSDs and TRIM along with BGC.
    Garbage Collection (GC) is the process of relocating existing data, deleting stale data, and creating empty blocks for new data
    All SSDs will have some form of GC – it is not an optional feature
    NAND flash cannot directly overwrite a page with data; it has to be first erased
    One full block of pages has to be erased, not just one page
    GC starts after each page has been written one time
    Valid data is consolidated and written into new blocks
    Invalid (replaced) data is ignored and gets erased
    Wear leveling mainly occurs during GC
    The OS tracks what files are present and what logical blocks are holding the files
    SSDs do not understand the file structure of an OS; they only track valid data locations reported by the OS
    When the OS deletes a file, it marks the file’s space in its logical table as free - It does not tell the drive anything
    When the OS writes a new file to the drive, it will eventually write to the previously used spaces in the table
    An SSD only knows data is no longer needed when the OS tells it to write to an address that already contains data
    How Trim Works -
    The OS sends a TRIM command at the point of file deletion
    The SSD marks the indicated locations as invalid data
    TRIM Features:
    ► Prevents GC on invalid data
    ► Increases the free space known to the SSD controller
    TRIM Benefits:
    ► Higher throughput – Faster host write speeds because less time writing for GC
    ► Improved endurance – Reduced writes to the flash
    Lower write amplification – Less data rewritten and more free space is available • TRIM does not generally work behind a RAID environment
    Anandtech 2009 SSD tutorial - http://www.anandtech.com/show/2738/5
    keeping 15-20% free will help (or figure how much you write to the drive in a month) seems if you get to 90% full can result in problems. Whether Durawrite or any other controller and firmware.

  • Anyone Running Two Macs with Logic?

    Just wondering how much time it saves and more power it gives...I have a Dual 2G and was thinking of one of the new Intels and using OSX's built in networking, with adat out of the second Mac back to my Fireface.
    I'm just trying to get a handle on how much help this would be to me, DSP wise, etc. I know I could put some of the VSL library on it, or whatever...
    I'm also a little confused about whether doing it like this is different than using the LOGIC node thing, and if so, which would help me more. I tend to use a lot of plug ins, some of which aren't LOGIC's.
    Thanks
    Tom

    X: Basically, Justin has given the info on LAN MIDI.Regarding the hardware route: just think of the slave computers as hardware synths,and you're near the mark. For example, on my DP 2.0 I run a single MOTU MIDI Express,giving me 8 ports.That is then connected to one of my AMT 8's.The only problem with that is V-Stack is capable of supporting 16x16,so to take full advantage, you'd have to double the number of MIDI interfaces.So,for that one computer alone you would require 4 MIDI interfaces. That's when hardware starts to become unwieldy. And expensive. I have five AMT/Unitors and a MOTU, but really don't wish to acquire more;so I'm going to take a look at MIDI over LAN. Maybe the answer is a hybrid configuration.
    Regarding getting the sound out. Each slave computer has a soundcard: in my case the excellent Hammerfalls. I take the ADATs out of those into the Quad's rig of MOTU's. The audio i/o's on each are freely configurable in both the Hammerfall's software and the V-Stack's/Kore's and all other standalone instruments. It's way, way more powerful and flexible than the node method.
    Hope this helps.

  • Is anyone using their MB with a separate monitor?

    I am wondering if using the MB with a separate monitor causes it to be noisier or hotter. I once tried to use a PB with a separate monitor and it was extremely noisy.

    Hello Bantock,
    Your MB should preform without any issue's. I of course suggest that you only use the external monitor when the AC adaptor is plugged in.

  • Has anyone nought their mac with educational price? Will there be any quality difference with the same unit without discount?

    Title

    The only one that allowed me to change a delivery schedule is UPS, and there I had to open an account and pay a $20 fee to change a delivery to another date, and specify morning or afternoon.  Could not refine it any further than that.
    Normally, if FedEx delivers and no one is there to sign, they will leave a note and try again the next day.  Will try to deliver three times and then return the item to the shipper.
    You can take their note to the FedEx location indicated and pick up the computer yourself.
    An alternative, if there is an Apple store convenient to you, order from Apple on-line for store pickup.  I have done that, also.  They will notify you by email when the computer is available at the store.  You will have to show proof of who you are to pick it up.

  • Is anyone else having problems with Firefox 8 dominating Ram?

    I am running osx 10.7.1 The only thing running is Firefox 8 (with add-ons disabled. One window, with only this tab open.) & activity monitor. While firefox is running with one tab open my system is using 1.92gb of ram. as soon as Firefox is quit all of that ram frees up.
    Does anyone have a solution to this? I cannot Run Firefox 8 without it making my system completely unusable.

    UPDATE: After upgrading to 8.0.1 I am down to using 808.6 mb of ram, with one tab open(still no add-on's enabled) as compared to 8.0's 1.92 gb. while this still isn't great (firefox 3 only used 630.4mb with 6 tabs open + 2 add-on's) it is starting to fall back down to the realm of acceptable numbers, I guess. I Throw this update up for discussion of the results. The more people I have numbers to compare with the more I can establish a "baseline normal" for version 8. so far I'm working with the ram usage for 10 similar systems(same os, same firefox, all w/ add-on's disabled & only 1 tab open) If you'd like to add your numbers to my research feel free to post them in a reply.

  • IMac with a Duet and a FW 800 drive?

    Anyone using an iMac with an external FW 800 drive and Duet (on the FW 400 port)? I have a Duet and a Glyph Portagig - interested in knowing if this would be a stable and solid setup with Logic.

    I'm using the Glyph off the FW800, but it is powered externally. Had a problem with the Glyph at first, but turned to be a manufacturing error which Glyph corrected..now works fine. The Duet is using the FW400 port and is powered off the port itself. I upgraded the RAM to 4gbs.
    Generally running anywhere from 12-24 tracks..depending on the song of course. Using very little of the software samples, but am freely using compressors, verbs and other sweeteners.
    I have installed all the updates of Logic Pro and Leopard (can't remember the numbers off the top of my head. Music style is rock/pop/country flavor.
    I may regret this , but everything is working flawlessly. So, I'm either a non-critical user, or it's working great...not sure which, other than I have no complaints. Love Logic and love the Apogee Duet.
