Memory options for iMac

Does the Late 2013 iMac with 3.5 GHz i7 support triple or quad channel memory? I am running Mavericks 10.9.5 with the stock 8GB and trying to find the highest possible memory bandwidth the machine can run.
In other words, will 2x8GB, 3x4GB, or 4x4GB will give the highest speed access to memory? I am not often seeing the used RAM exceed 7GB, so I am not too worried about passing 12GB if triple channel is supported.

BrianAdam3342,
The answer is really pretty simple, iMacs are fussy about upgraded RAM installed. If you want your machine to work reliably follow these three rules of thumb and you will likely be rewarded with years trouble free RAM use. :
Buy high quality RAM from recommended sources such as OWC (www.macsales.com) or Crucial
Stick with the specifications Apple recommends.
Install matched sets of RAM. If you are going to continue using your existing 8GB,
add 2x4GB = 12 GB
add 2x8GB = 24 GB or if you want to max out at 32GB
add 4x8GB = 32 GB
Add the RAM in options 1 & 2 to the 2 empty slots when you open the iMac's RAM door.

    Fusion Drive option for iMac 21.5" late 2013 will upgrade main SATA HDD to 7200rpm model? Or just add SSD to standart 5400 rpm HDD for 21.5"?
    Thank you for your attention.

    You can't add an internal drive, but you can add as much storage as you want via Thunderbolt.

    If you can, you want MATCHED, TRIPPLE CHANNEL, ECC registered ram with the same timings as the original ram.  I found that 1333mhz ram of that type is a bit easier to find these days (any faster ram will work in the your macpro).  Anyhoo, I found 12 GB of ram 3x4gb (oh yeah, and tripple channel ram likes to be installed in three's so if you can stick with only 3 chips of ram unless you are making it out or something.) for like $150.  If you keep your eyes pealed you can get a great deal.

  • PCI Option For iMac

    I own a professional recording studio. The studio and the software I use was purchased with a Mac in mind from the start. Unfortunately after spending far too much money on my mics, outboard gear, mixing console and the rest the bank was broke and a Mac capable of running the studio was not in the budget. I had always had a tower in mind because it always was dominant Mac and could be expanded. Also for one major reason, use PCI based plugins and my interface for recording needs a PCI slot to run as well. With the advances in Mac over the last couple years months the iMac could fit my needs far better than a tower, and with a 24" screen, it would be ideal for mixing. Are there PCI options out there for iMacs, such as something that would plug in via firewire or ethernet? Thought I's ask the experts.
    thanks

    I hate to disappoint you but iMacs are not designed for expansion. They do not have available PCI slots for third-party cards. For that you need a tower style Mac. You might consider something from the G4 or early G5 Power Mac tower lines such as the QuickSilver or Mirrored Drive Door G4s or one of the earlier G5 models that still have PCI slots. Later G5s have PCI-X slots. Because these are no longer in production they can be purchased used through eBay or some online retailers who vend used/refurbed older Macs.

  • External Monitor Options for iMac?

    I have an iMac and have been using a lot with my 7D files. They look great, but I would like to have an external monitor output. Any ideas on output modules for iMac? Thanks!

    is if there is a Firewire out that can send my Color display out to my Trinitron monitor, like FCP
    No, absolutely not. COLOR does not support FireWire output. The developer intended the application to be used with a PCIe Video I/O interface, (Kona, for example, as opposed to GPU) supporting HD-SDI output, and the fixed output gamma characteristic of 2.2 was assigned as default to support that.
    *All other approaches* are considered to be +ad hoc+ substitutes and are +de facto+ "as is". The policy should be read as -- "we made it one way which functions very precisely; if you want something else, that's your business"... but for a very large number of non-broadcast content producers, that's fine. It doesn't matter if its technically "wrong", as long as there is a result, not to imply that no one cares about the products they are generating -- but there are obviously some very large knowledge gaps in the consuming population in this area.
    That's my possibly cynical interpretation of the history and situation...

  • Add Move to Memory option for Applications in Settings for Dell Venue 7 OS

    The "Move to Memory Card" option was not enabled by Dell. It should be. <Forum violation = soliciting>. Dell, please add this feature. It is useless to have a memory card if you can't store apps on it. That's the main purpose of it. The camera is so slow it really isn't going to be useful to store photos on memory card, not even sure this option is enabled LOL. Anyways. Need to be able to store Apps and increase system memory to speed up operation. As it is anything over 5GB in total apps will bog down the Venue 7 making it basically useless. I feel like it's like using dial-up all over again. I should have got the iPad Air.

    I'm running a 32gb card for music and movies.  Have no problems.  Load the card via computer attached with usb cable.

  • Power options for iMac

    We are ready to order a new iMac.
    Of the options, which is the most important for Photoshop CS3/digital photography work:
    A) the fastest video card, given two good choices
    2.8GHz Intel Core 2 Duo or 3.06GHz Intel Core 2 Duo
    B)the most powerful processor
    ATI Radeon HD 2600 PRO w/256MB GDDR3 or ATI Radeon HD 2600 PRO w/256MB GDDR3
    C) the most RAM
    I've pretty much decided on the maximum 4 gigs of RAM, but am trying to figure out if I need the MOST in the other two departments. I am not a gamer, don't do video and am switching from PCs to Mac. Whereas I'd like to keep the price down, I do not want to be underpowered just to save a couple hundred bucks and have no one locally for a reality check.

    >We are ready to order a new iMac. ...for Photoshop CS3/digital photography work
    The latest iMacs will accept 4 GB RAM and have a FW800 port to add the necessary external drives. Today such a configuration indeed will do an adequate job of just running PSCS3 - but just running the apps does not make a box the best choice.
    For life cycle and for performance reasons IMO iMacs are much less good choices than towers for desktop graphics workstations. iMacs are subject to the very significant limitations noted below.
    Just the RAM limitation alone is an obvious serious limiter even with today's app versions, and as RAM prices continually fall modern apps and the OS are taking advantage of more and more RAM all the time. E.g. even though Photoshop can only directly address ~3 GB RAM, PS running under OS X has shown improved performance with 8 GB and more RAM for about 5 years now.
    Boxes purchased today will be running the OSs/apps of the next few years, when the 4 GB limitation of iMacs will become even more significantly limiting. I consider RAM the bargain value performance enhancer today and it will only get better, so IMO limiting a graphics desktop box destined for 2009-2012 usage to 4 GB max RAM is poor life-cycle decision making.
    I would also point out that, as consumer boxes, iMacs now only come with glossy displays. Matte vs. glossy is a matter of personal preference, but personally I find glossy unacceptable. Most graphics pros do not want their displays arbitrarily adding contrast and saturation to their work. That, for me, makes iMacs unacceptable at any price.
    Some pros get around the iMac's glossy display issue by having their second display a matte and just using the iMac for palettes. I guess that could work but it is not something I would want to do because frequently I compare images on both displays.
    All Photoshop versions require a separate hard drive for scratch to achieve best performance. That starts an iMac with at least one permanently attached external drive limited to FW speeds. The SATA of MPs is far preferable. Note too that if DSLR batch image handling were to creep into the usage during the life of the box that single FW800 port will also be limiting as regards disk i/o.
    Any new box should be planned for the apps and OS versions expected to be in use during the life of the new box in addition to current apps. That includes CS4, OS 10.6 and beyond. And, IMO when buying for the graphics-pro future we should be equipping folks with the ability to handle image management apps like Aperture because managing DSLR captures will become more and more prevalent a need over the life of most new desktop graphics boxes.
    iMacs are nice consumer boxes and I have purchased them for family members, but they are much less-good desktop choices for graphics professionals. Better would be a refurbished Mac Pro, even the 2006 model. Note also FWIW that new Macs of various flavors will be announced between now and Mac Expo SF in January, starting with laptops tomorrow (new MPs likely sometime between now and Q2 2009).

  • Limited Memory Options For ILSR?

    Hi all
    I'm about to go out and purchase a K7N2-ILSR but I'm in South Africa and my memory choices are only Hynix, Transcend and Samsung.
    I've been reading all the posts about memory issues with the ILSR and was wandering if someone can tell which is the better brand of the 3 to go with.
    I will either get an XP2600 or XP2800 with the board.
    Thanks
    John

    Our exchange rate isn't too healthy and I wouldn't even know where to begin to look for ram on the net that would actually ship to here.
    I thought about the KT600 but from what I understand the NF2 performance is better and the features on the ILSR outway the KT6-LSR.
    I can get the board/memory straight from the distributors so maybe I should talk to a technician and see how many returns they've had.
    The one distributor sells MSI boards/Hynix and Samsung memory and the other MSI boards and Transcend memory.
    My last option is to get ram (Kingston) from another distributor in another city but I noticed that Kingston and ILSR don't get on.
    Would I notice the performance difference between ILSR and KT6-LSR?

  • Question about Memory Upgrade for iMac G3/350 - Slot Loading

    I was thinking of upgrading my memory and found this on eBay
    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350070149602
    The auction says that it won't work in an apple computer but it looks like it should. Any help would be appreciated.
    Thanks,
    James S.

    I agree with Richard; if the seller says it won't work in a Mac, why bother? It's likely to be hi-density, which either won;t work or will show up in a Mac as only half its true size.
    I've been hanging around these forums for nearly seven years and have seen a lot of tears shed over alleged Mac RAM bought on eBay. Your mileage may vary, but I get RAM for our 13 Macs for online venders who are Mac-savvy. They all work.

  • Memory options for a executable jar launched for an icon

    I'm running windows xp and have created a java application in an executable jar file. I would like to run this from the desktop as an icon. I have been able to do this by putting a shortcut to the jar file on the desktop. . So far so good... but I need to specify a larger memory maximum to handle larger files in this applicaiton. From a command prompt this would be "java -Xmx128m -jar myjar.jar" -- does anyone know how to add interperter options into a shortcut, or some other way to do this?
    Thanks.

    You can do this by using the Windows Explorer and using the File / New / Shortcut menu item. Select the javaw.exe program and enter the full command line with options and the jar file, something like ...
    %windir%\SYSTEM32\javaw.exe -Xmx128m -jar C:\java\myJar.jar
    This shortcut can then be put on the desktop.

  • SSD option for iMac when working off external worth it.

    Ordering the maxed out iMac 27 i7 16g ram etc. is the SSD helpful if I work off externals for all my media etc.
    I have the Air and see the boost for start up and application load times. Other than that is it really a boost for working with say FCP with media on an external drive.
    I would assume the boost only helps if the files are on the actual ssd which given its size is not possible.
    So a bottleneck occurs.
    Just could use 600$ in other areas if I only gain a fast startup and fast app loading.
    Thanks

    Thank you and so well spoken baltwo
    I have gotten so much "your crazy" from my buddy for spending tha max on everything else why not just SSD.
    Just seemed at 600$ what's the gain if all my content is bottle necked on a second drive Or external....what's the point. Rather spend that cash on proper backing up solutions etc.
    Guess I was feeling what we all are getting caught up in this SSD speed vacum. I have the air it's snappy and great but all files are residing on the drive. Not happening on an iMac so was wondering how much of gain is true to form.

  • Wide gamut options for iMac, what are they

    We have a new iMac 22 inch model and when we try to calibrate it as a wide gamut monitor using Datacolor Spyder Studio we get the error that this is not a wide gamut monitor. *** I thought this was the ultimate in displays!
    What do we have to do to get a wide gamut display? We really don't want to add a monitor

    Color gamut is a bit worse on the new panel vs. the old one from what I can tell. Both are WLED backlit which limits the  spectrum of colors they can accurately reproduce.

  • Memory Options for Manifest?

    Hi all,
    Is there a way to set the JVM memory arguments (like -Xms and -Xmx) in the manifest or similar mechanism?
    I'm converting an application from being launched with a .bat file to a double-clickable .jar, but i'm seeing a bit performance hit regarding memory.
    Thanks.

    Appending the argument after the file name does not work in my tests. It appears to be ignored (as might be expected).
    I used the following target spec:
        "C:\Program Files\Company\My.jar" -Xmx256gand the JAR ran successfully.
    It should have failed with:
    Invalid maximum heap size: -Xmx256g
    The specified size exceeds the maximum representable size.
    Could not create the Java virtual machine.So, has anybody solved this?

  • Mounting options for iMac G5

    I need to attach an iMac G5 to mounting arm. The rep that sales the mounts said that his will attach to standard flat screen interface called VESA. The VESA interface is either 75mm or 100mm. Anyone tried to attach an iMac G5 to one of these?
    Thanks

    Thanks.
    In another thread I found that the Apple Store sells a mounting bracket that replaces the stand. This bracket has VESA compliant holes at 100mm.
