Only 8 out of 16GB ram is visible in Windows 7 64bit

I'm running a brand new Late 2012 i7 iMac with Fusion Drive, 16GB of ram, etc. I just put a bootcamp partition with WIndows 7 Pro x64 on the Fusion Drive  today and after all the drivers and updates were applied the system does not allow usage of the full 16GB installed in the machine (this was also the case prior to driver/updates installation). Can anyone supply a solution or a reason why this is the case?

Hello folks,
I have been facing the same problem until right now. All above suggested methods failed (as it did for Jeff0123) . But after long research on that issue I think I found the reason (but no proper solution yet).
MS Windows 8 and 2012 use a new printer driver generation based on XPS. Which means drivers like "generic text-only" won't work properly depending on the method the data is sent to the printer. In my case the
same way like Jeff0123 tried to access the printers.
See link http://support.microsoft.com/kb/2779300
One solution might be to use API calls. I have also found a site which shows an example project for thermal slip printing. The VB.NET source code there features a wrapper class for all API calls. The functions you find behave pretty similar to the ones of
the posted C# code example of Jeff0123. I did a small test so far and for my needs that works fine.
Although the page is in German you can find the mentioned class by searching for "Public
Class RawPrinter". Beside the comments the class methods are written in English. You find the class here: http://www.vbarchiv.net/tipps/tipp_2375-kassenbon-drucker-mit-vbnet-oder-c-per-esc-pos-befehle-ansprechen.html
Hope that might help for at least a few of you. So long!

  • Upgrade from 4x2 GB to 2x8 GB Ram results in strange Windows 7 64bit behavior

    I wanted to upgrade my System, swapped the 4x2 GB (Adata 1600G) to 2x8 GB (G.Skill F3-2133C9D 16GXH) Ram to the Dual Channel Slots (2 x Blue)
    The System asks me to enter Setup with F1 recognizing the mem change.
    I have OC Genie active and tried it later without.
    When I boot to Windows with the new RAM my NVIDIA Card has a yellow exclamation mark in my device list. Also NVIDIA Software can`t access the card telling me I would have not such an device active. I tried to reinstall the drivers without success.
    I tried a couple of changes in bios and rebootet, but gave up after 40 Minutes of experimenting.
    After I went back to my old RAM the system runs smooth like always.
    Now I hope someone here can give me the right advice what to do, or ì`ll sent them back to the shop.
    System:
    MSI Z68A-GD80 (B3) (MS-7672) (Bios V20.1 01/09/2013)
    Intel Core I5-2500k @ 4200
    NVIDIA N560GTX-Ti
    New Ram: G.Skill RipjawsX F3-2133C9D 16GXH
    Old Ram: A-data 1600G @ 667 MHZ
    What I did:
    1 G.Skill Ram in DIMM1 works good, also with OC
    changed the other one G.Skill module workd ok (to be sure both are ok)
    as soon as I add the second RAM NVIDIA Card doesnt work correctly, some programs give me strange warnings, blue screens, random crashes.
    I choosed DIMM1 + 3 (Blue) or DIMM2 +4 and all other positions with no good result.
    Even with default settings no luck.
     i get the following error on my nvidia card in the device manager
    "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
    Is it an error on the motherboard ?
    How can I proof that? Any tools ? I`m really out of ideas ...
    Thank you

    thank you. that`s what I had in my back mind
    I didn`t thought that the performance increase is that less. any reviews you can recommend ?
    Here is the memory scaling on a Core i7 2600K:
    As you can see, in both cases (non-3D and 3D apps) the performances boost is close to zero.
    So again: for all the current Core i5 / Core i7 processors, DDR3-1600 is the best match.
    Above that, nothing but troubles.

  • Yosemite only recognises 16gb RAM out of 32gb

    Hi guys,
    Until a month ago when I upgraded to Yosemite, Maverick recognised the 32gb RAM physically installed on my machine, after the upgrade to Yosemite (currently 10.10.1), the system ONLY recognises 16gb RAM.
    I have a 27-inch mid 2010 iMac, 2.93 GHz Intel Core i7. All 4 slots are used, but the system should read 4 x 8 gb, but it only reads 4 x 4.
    Already tried resetting the PRAM and SMC, but nothing.
    Any clues, advice... something ?

    Thanks for your reply and... I must say I feel like an idiot, worst like a moron.
    After reading what you replied, I took a moment to think and I just realised I mistook the computers I have!!!! D'oh!
    The one in my office is the old one with just 16gb and the one at home is the one with 32gb!
    I know, I know, pure idiot... just coming back from a long vacation completely disconnected from technology and no matter how many times I saw the SYSTEM PROFILE I never realised it was the mid 2010 iMac.
    Laugh all you want, mock me... I deserve it.
    Thanks anyway!

  • Out of memory with 16gb ram?

    I am running CS4 on an 3.0 8 Core Mac Pro with 16gb of ram and a raid 0 scratch drive made from 6x15k drives. I had my memory usage set to 92% with 10.5.6. I recenetly upgraded to Snow Leoaprd and was working on a 3mb file, with no other applications runining, besides firefox.  I was trying to use the quick selection tool and when I tried taking away from the selection I got the "out of memory (ram)" error. So I dropped the ram usage for ps it down to 85% and that seemed to work. Is this normal for Snow Leoaprd? In the past, people had recommended that if you had over 10gb of ram to set your ram usage to 100%, but I see that must no longer be the case?
    Thanks,
    Steve

    Now I just tried opening up one page of a 9pg pdf file in CS4, and I got the "not enough memory" error again? I have 10.5.6 on another drive, so I went back to that operatinig system and tried opeing the same file in CS4 with the memory usage set at 92% and it opened up fine.

I thought I had a defected newly purchased keyboard. I pulled out my older wireless keyboard, and the same thing happened. It must not be the keyboard if it happened to two different keyboards. I have a habit of restarting my computer, when things don't work, I find it helps, and sure enough, everything works. Today, it happened again. Does anyone know what is causing this to happen?

  • Will 16GB RAM wear out the SSD? rMBP

    Will 16GB RAM in my 2014 Retina Macbook Pro wear out the SSD? I plan on keeping it for 4 years.
    Can the SSD, seeing how as the new Macbooks have everything soldered I think, be replaced at all if it runs out of write cycles?

    The SSDs of today have a Mean Time Between Failure rate equal to that of the hard drives.  That means you can use the modern SSD as much as you like as those failure rates are in many, many years.  The first and second generation SSDs had vey short lifetimes.  All of that has changed and you can feel free to use it as much as you like.
    Your other comment, the current generation of Mac OS X's, Lion, Mountain Lion and Mavericks, do grab a great deal of the available installed memory.  So it looks as though all of the memory is in use.  Actually it is not but is simply grabbed by the OS X so it can quickly allocate memory as needed.  More important to look at than the available memory is the Memory Pressure.  Go to Applications > Utilities > Activity Monitor and click on Memory top center of the window.  Then look at the Memory Pressure bottom center.  As long as that is displayed as green you are great.  Yellow and you are loading up the memory.  Red and you are using virtual memory, the SSD, for swap space.  With 16 GB ram it is not likely you will ever see that go yellow.

  • Upgraded 16gb ram. Only using 4gb

    Hi,
    I have an iMac 27" Mac OS X 10.6.8. I upgraded the memory from 4gb to 16gb. After working on it I have noticed that the memory that is using within the activity monitor, it only uses 4gb. I'm usually using Pro Tools 8 LE for it, I have a lot of troubles with memory.
    Any Ideas to start using the 16gb ram?
    Thanks in advance

    Install Sophos: https://discussions.apple.com/message/18316360#18316360
    That is pure sarcasm by the way. Don't install Sophos.
    What you are seeing is completely normal. Your iMac uses what it needs, and your usage indicates that it needs less than 25% of its available memory. If it needs more it will take more. 16 GB is enormous.
    Enjoy your Mac.

  • Issues with sleep/wake feature after 16GB RAM upgrade in my MacBook Pro. Any thoughts?

    Just installed a 16GB RAM upgrade in my MacBook Pro and now it doesn't wake up on it's own when I open the lid. I have to press the power button. It works fine with a smaller RAM upgrade.
    I've tried putting in just one of the 8GB modules and the sleep/wake feature works as normal so there isn't a problem with the RAM modules that I've bought (Crucial.com). I've also put in a combination of Apple's original RAM and the new ones to make 10GB (8GB + 2GB), and the sleep/wake feature works on that too. Put both 8GB modules back in and the MacBook doesn't wake up when I open the lid, I have to press the power button to wake it up. The MacBook itself works fine, super fast and the memory is recognised on 'About This Mac', the sleep/wake issue is the only problem I'm having with the 16GB RAM.
    Any thoughts on this? Has anybody else had this sleep/wake issue like this when upgrading RAM?

    I upgraded my early 2011 MBP to 16 gigs with Crucial. My machine would not sleep properly, because when I tried to wake it, it would wake from its hibernate image file. This is the issue I've seen here in this list.
    I tried all the suggestions I saw on these groups. Nothing helped. I contacted Crucial, who suggested that if their RAM was defective, they'd replace it per their warranty process. I needed some proof it was their RAM causing the problem.
    I put the original 8 gigs RAM back in the machine (2 4 gig sticks), and it behaved normally. I then put one stick of Crucial RAM in, all by itself. The machine behaved normally. I put the other stick of Crucial RAM back in, and took the first one out. The machine would not properly sleep and wake from sleep. This proved that one stick was causing the problem, and the other was not.
    Defective RAM!
    I then requested and received an RMA from Crucial to send the defective RAM back. They paid shipping. I got new sticks of RAM about a week later. These new sticks of RAM work properly. No sleep issues.
    I'm surprised and disappointed to say that this is not the first time I've received defective RAM from Crucial. I've purchased from them for years, and had GREAT service and received high quality products. The past couple years my experience has been different.
    I'm still pretty steamed about this, as I spent a great deal of time trying to diagnose the problem and fix it. I don't really have that kind of time to waste. My expectation was that their RAM was high quality, and unlikely to be at fault.
    Perhaps this is just a bad batch of RAM. I get that. I can forgive them once. But this has happened twice in the past three years. I'll look elsewhere for my next memory purchase.
    Keep in mind that their customer ratings are generally very high. My experience is probably  isolated.

  • 15" Macbook Pro mid-2010, 16GB RAM upgrade possible?

    Hi all,
    I've been looking around all the support forums and questions asked etc..
    But I can't find a definitive answer about support for the 15" mid-2010 MBP being able to use 16GB (and be stable).
    I'm aware that it's perfectly fine on the 13" model, however I have the 15" i7.
    From what I've been reading it's because of the motherboard/Graphics chip/EFI BIOS incompatibiity with anything more than 8GB. (Which is silly really, as the same Intel core i7 can have up too at least 32GB of RAM on any none-Mac system.)
    Have Apple not pushed out an EFI BIOS update that could allow the use of 16GB RAM?
    If this has been clearly answered elsewhere (and I haven't found it), feel free to point me in the right direction.
    Thanks, Jon.

    Unfortunately, 8GB is the limit. I have the same machine. Why it works on the 13" and not the 15" is ridiculous, but that's how it is.

  • Early 2013 Macbook Pro Retina 2.7 i7 512GB SSD and 16gb Ram with Serious Cuda Problems! Trying to teach Apple their Macbook Pro Retina isn't a Pro Jan. 11. 2015.

    Apple replaced the logic board, wiped the computer, did a fresh instal of the OS, and also a fresh instal of all the programs during the beginning of 2015. The GeekBench scores are the highest of any of the similar computers (at least on the day of my testing). But here's what's happening. The Macbook Pro Retina has a GeForce GT 650m with Cuda Technology and it can't handle editing in Premiere Pro with Cuda Acceleration turned on. Open CL, a second form of graphic acceleration on the Macbook Pro, appears to be functioning properly.
    At the Apple Store on 1-10-2015, I was told that since the logic board and the graphic cards have been replaced that there is nothing they can do and they recommend contacting Corporate. This comes after they told me to buy a new logic board and that that would solve the problem. This comes after Apple did not listen, for over a month, about the possibility that they didn't properly build a professional notebook computer.
    The computer displays a black program monitor screen, at random times, when the user edits footage with Cuda Acceleration enabled. It used to lead to an entire system crash and/or a Premiere Pro crash before the operating system was completely re-installed. My solution, since I bought the computer, was to edit in Open CL... However, I've come to learn that there is a major difference in performance between Open CL and Cuda Acceleration.
    For the Macbook Pro Retina, Adobe Media Encoder render times are about 20% faster with Cuda Acceleration than Open CL. The 2013 Macbook Pro Retina appears to be able to handle Cuda Acceleration in Media Encoder, but I have had a number of issues leading to program crashes on every project before the new logic board and operating system were installed. For over a year and a half, I actually never used Cuda Acceleration. Having sent every crash report and user data to Apple over that time, I truly expected an update of some sorts and it never came.
    FYI: The latest Macbook Pro Retina uses the GeForce GT 750m... This is essentially the same graphic card that performs about 10 - 20% faster due to a new "boost mode." More importantly, it actually has the exact same number of Cuda cores. Having the same number of Cuda Cores means that the Cuda Acceleration is essentially the same when exporting or viewing video. To prove a point to Apple that their 2013 Macbook Pro Retina isn't functioning properly, I bought the latest computer with the 2.5 i7, 16gb Ram, 512gb SSD and I can honestly say that the 2014 model works perfectly fine with Cuda Acceleration turned on while editing in Premiere. I can also say that a proper render test proved the 2013 and 2014 model to be the exact same.
    I'm new to this whole pay $2700 for a computer that your manufacturer didn't / can't test properly, so I will be contacting Apple and speaking with Senior Advisors, their Customer Support division, and will soon speak with their Corporate branch. I'm confident that the Early 2013 Macbook Pro Retina with a 2.7 i7 16gb Ram and a 512 SSD is nearly the same at rendering video and editing video, provided the Cuda Acceleration works, as their latest 2014 Macbook Pro Retina with the 2.5 i7 processor 16gb Ram, and a 512 SSD. It's truly a great computer and a great build, minus their current inability to properly test / diagnose their computer.
    Knowing that the latest graphic card in the Macbook Pro lineup is essentially the same model, I feel that Apple is not directly looking into the viability and life span of their current Macbook Pro Retina product line. They can't test for performance issues relating to their graphic cards, so why consider buying from them when the end user is actually in a position to experience up to a 20% decrease in certain professional programs.
    For future reference, I'd strongly urge other individuals to avoid purchasing Apple products if they offer Cuda Technology. In my opinion, Apple is an Open CL organization, at best, who is not responsibly manufacturing / producing computers that fit their organization's strengths. For a fact, they can't test their Cuda Technology and won't even attempt to address Cuda Acceleration errors for Apple owners (01-11-2015). I say this having walked out of the Apple Store on 1-10-2015 with virtually no support other than to contact Corporate.

  • 13" MacBook Pro with Retina 256gb SSD and 16gb ram?

    So I have decided to go with a 13" MacBook Pro with Retina.
    I am now deciding on how to customize it...
    My uses are:
    Primary -> Writing. I am an aspiring writer/ future published author, and this unit will serve as a primary storage unit for on-the-go writing. The SSD will help in this capacity, tremendously, as well as battery life, as inspiration to write can happen anywhere. I found he typability to be easier on the MacBook Pro as well, rather than the Air.
    Secondary -> Music, videos, gaming.
    Basically, I am aware that the crispness of the rPro is apparent. I am not worried so much by the music, or videos, or even browsing part, as I'm sure its quite speedy.
    What I am thinking is the might of the 4gb ram, 128gb SSD storage.
    Would it be more worthwhile, since I plan to use this for 5+ years, to go for the little bit extra and get the 8gb ram, 256gb SSD storage unit, for only $200 extra. This seems a minor fee considering the length at which I plan to use and keep this.
    That being said, I still play some older games and whatnot, with the possibility of playing World of Warcraft in the future... That being said, and knowing that Macs are not gaming powerhouses (unless you wish to go 15"+), would it be worthwhile to splurge another $200 for the 16GB ram? What major differences would doubling the 8 to 16 do for me and the performance of this MacBook?
    Thanks in advance!
    Nick

    Since it is not possible to upgrade the RAM after purchase (it is soldered to the logicboard), I would definitely opt for 8GB. The same goes for the SSD- I would opt for double the storage. Though it is possible to upgrade your drive in the future, it comes at the cost of installing it yourself and potentially voiding any Apple warranty.
    It would not be worthwhile to spend another 200$ on 16gb of RAM, IMO for your purposes. The lack of a discrete GPU and a duel core processor is what will limit gaming performance. 8GB of RAM is enough, in itself.
    Rather than spending an additional $400 dollars, either spend the extra $200 for the 8gb 256GB model, or consider the 15'' entry level model for $700 extra dollars-which would be plently powerful enough for your purposes.

  • Macbook Pro 13" Late 2011 16gb RAM error

    Hi,
    I've got a 13" Macbook Pro Late 2011, Intel i5 2.4ghz, 16gb RAM Corsair (mac branded), 500gb 7200rpm Seagate Momentus.
    Recently my mac keeps restarting 3-4 times a day. I've done the Apple Hardware Test and I found out a problem with my memory (4MEM/9/40000000).
    So I've tested each stick and the funny thing is that they both works well (without reporting errors) alone. When i put the second stick (no matter if the first or the second one), AHT shows up the error.
    So, each stick alone -> OK
    Two of them together -> BAD
    I've tested also the two sticks that originally came with my mac (2x2gb) and everything went fine.
    What do you think people?
    Thanks!

    Me too!

  • MacBook Pro 13" Late 2011, 16GB RAM and Apple Premium Service Center

    Hello all,
    My dad has a MacBook Pro 13" Late 2011, it came with a 4GB RAM. When he got Parallels and installed Windows 8, 4GB RAM were not enough to even deal with Safari so he had to buy 16GB RAM from Cruical. Today when he went to Apple Premium Service Center here in Qatar (51 East) they refused to install the x2 8GB RAM and only installed one of them. They kept warning my dad that installing the whole 16GB can cause issues with the MacBook Pro HDD and can make it go faulty. I wanted to ask if installing RAMs can pose the HDD life to any danger. Because my dad uses his Mac for work and wouldn't like to lose any of his files against small additional speed.
    Thanks.
