• I need to upgrade my Mac (MacBook white unibody mid 2010) with a SSD (and iMac mid-2010) and the RAM and SSD

  I need to upgrade my Mac (white unibody MacBook mid-2010) with a SSD (and iMac mid-2010) and the RAM and SSD: I look to buy upgrades site Crucial and OWC site and there is a little difference, in terms of money: it's better to buy the Crucial site or OWC site.

  They have good tools to find compatible parts for your Mac models.  The OWC took is here

  http://eShop.MacSales.com/MyOWC/

  OWC tends to have the most detailed information on the Mac.  If I look to the top of the part to OWC and review specifications.  OWC offers often information based on the Mac-specific tests.  If Crucial offer something similar for a substantially lower price, buy it from Crucial.  I'm sure they have a refund is not political, if a part they say is compatible.  I bought the RAM and SSD both Crucial and OWC.  From my experience, be it high quality.

  For the 2010 iMac, OWC also offers a "kit" (with the tools and support) to replace the hard drive of 3.5 inches with a 2.5-inch SSD.  Eventually, if it's a 27-inch iMac, I think that you can Add the SSD instead of replace the hard drive.  And they have self-produced how-to videos on the process, related to many of their lists of products.  OWC provides a lot of information with added value and service for Mac users.

  OWC also offers kits to replace the optical drive on some Macs (including MacBooks) with an SSD (as a secondary internal drive).

• I have a faulty ram (top) slot for a Mid 2012 Macbook Pro 13 "i5.  Can I install a 8 GB Ram in the slot below or is maximally 4 GB?

  I have a faulty ram (top) slot for a Mid 2012 Macbook Pro 13 "i5.  Can I install a 8 GB Ram in the slot below or is maximally 4 GB?

  This was after the 3 beep error and I couldn't restart the Mac with one of the 2 GB of Ram into the lower slot.

  Is there a way to test if the top housing is faulty or just dirty?

  Thank you

  Yes, the MBP will work with a single module of RAM installed, but there will be a slight performance decrease.  A MBP 2012 will accept a module of 8 GB RAM.

  Is there a way to test if the top housing is faulty or just dirty?

  Install each RAM module individually in each slot, leaving the other empty.  If the two RAM modules work in a slot and not the other, the slot is faulty.  Sometimes the adjustment screw can resuscitate the slot.  If this is not the case, make an appointment at an Apple store for a FREE evaluation.

• iMac 27 2010 graphics card / ram problem

  Hello - read through the form and try to isolate the problem.  A week ago my end 2010 iMac 27 I7, 12 GB of Crucial Ram, OSX Yosemite went screwy - icons went fuzzy, and the system has just stopped responding. I tried not just pull the plug, but the computer was out of order, so I had to pull the plug. Please keep in mind it was a day hot here in New York and I've come for a quick moment to remove some files and did not close the windows a turn on the AC, so they probably overheated system or so I guess

  Anyway, after a few hours and I came back home and turned back on the iMac. Immediately, I noticed some pale red bans on the screen. The system has been restarted slowly and then it stop at halfway however and just go to the gray screen. I did a reboot, re-installed the operating system made the system check, but the failure of operating system to kick when I do a normal restart, and I am only able to operate the computer in Mode safe.

  Is there a way I can understand if the RAM is the question, the graphics card, or if it's the OS? A faulty graphics card will prevent the system from starting normally? I have the same question when I open it on safe mode?

  I'm trying to see if there is a way to save the iMac and get more use out of it, but at the same time a few years if it's gong to fix an expensive that I can't do on my own, so maybe its not worth what's now 5-6yrld of fixing iMac little matter how the computer cost me back in 2010.

  Thanks for your help and sorry if this question has been answered countless times before.

  Most likely graphics card problem...

  Note:

  One way to test is to boot from the HD, (now shift key at startup), run utility disk in Applications > utilities, then highlight your reader, click on repair permissions, test for problem in Mode safe...

  PS. secure boot can remain on the gray radian for a long time, let go, he's trying to repair the hard drive & trash/rebuild the cache files

  Reboot, try again.

  If it does so only in ordinary chest, there could be a problem material such as Video card, (the Quartz is disabled in Safe Mode), or airport, some USB or Firewire devices, or the module in part 3, Check System Preferences > accounts (users and groups in later versions of OS x) > login items window to see if she or something relevant is listed. Or a stray process eating RAM.

• iMac is not using available RAM

  My 2010 27 "iMac (running Capitan) use not all of the available memory. I have 8 GB and up until 1 month ago it used every last bit of RAM (as it should). However, since then he has been leaving 1, 5-2 GB of free throughout the day, no matter what I do, and my understanding of the operating system, it's that I should * not * take this as a good sign. Adds that the fact that I have reason to believe that my HARD drive is almost its disappearance and I'm not thrilled on the additional workload, it is probably ignoring manipulation of programs available RAM (and Yes, they've all been gloomy at the end).

  I know there are a lot of intel I leave so please ask away.

  Thank you

  Ivan

  OS X will use as much or as little RAM as it should.  Having RAM unused is not a problem in and of itself. It simply means that the Mac does not require that it based on the workload, it is put under currently.

  There is really no reason to be alarmed of the it. Especially if the pressure indicator of memory in the activity monitor application is displayed in green. Really, there is no way to force the OS X to use up RAM.

  If your hard drive is questions and slow down things, which should have no impact on the use of the RAM at all.

  You might want to think about a new hard drive, however.

• Mid range iMac with 16 GB of RAM or Imac 4 k with 8 GB?

  Hello

  I have some doubts about my purchase between this two imac. Now, I have a Macbook pro 15 "mid-2010, intel core i5 2, 53ghz, and I upgraded the ram from 4 GB to 8 GB two years ago. It works well, but little work with after effects (not professional) is so slow, just now, and other apps open like photoshop, illustrator(professional use) at the same time is not a good idea. I think that the CPU is limiting.

  So, I have two doubts:

  -J' I notice a significant difference in performance with a new imac like that?

  -If I decide finally buy a while ago, what could be the best decision to have a good computer for another 6 years and my work: mid-range imac with 16 GB or imac 4 k with 8 GB (two 21.5 because I prefer)? Top models are so much money for me.

  Thank you guys.

  (Sorry for my English is not my language)

  For "future verification", it is not wise to buy an iMac 21.5 "with less the amount of maximum available ram. 8 GB can be enough today that is not being upgraded after purchase and you may quickly regret your decision.

• How to replace inside the faulty RAM on Satellite M40X 141?

  Hello world
  I strongly suspect a main RAM failure. It is possible to replace it by removing a slot or is it is soldered to the motherboard?
  In this case is the only way to fix Board replacement?
  Like the RAM to be located under the keyboard, which is the best way to proceed for replacement?

  Thank you much for the help.

  apipop

  Hey Popy

  The laptop has 2 slots, but only one is scalable user.
  I think the a slot is located under the keyboard and the expandable slot, you will find at the bottom of the unit.

  I think you n t a lot of experience with these replacements. Am I wrong?
  I think that these replacement or controls are not very easy for someone who doesn't have enough experience.
  So I think you should ask a technician or help!

• SP4320... Faulty RAM - Bank B?

  Hello! ;)
  I have a SP4320 with 128 MB of RAM (64 MB + 64 MB Module aboard).
  I wanted to update the RAM with a 2nd module of RAM (64 MB).
  but I discovered that each memory module that I insert in the slot B (the black in my case) is not working properly.
  for example: when I put the crack A 64 MB Module in the slot B is f * ed up. (win2k-> bluescreens, Doc memory RAM Diag V2.0-> check memory fails) :(
  but in the slot has the same module works without problem.
  is this a defect of material known on this type of laptop?
  and is there a solution for this problem without changing the motherboard?
  It's a little annoying because a 256 MB SO - DIMM SD - RAM costs about 40 euros :(
  and I don't even know if the NB accepts these great modules...

  Edit: Sorry for my English 'strange'... ;)

  Hello

  Your device can handle with 320 MB RAM maximum. The compatible RAM modules are:
  PA3003U - 1 M 03 32MB MEMORY KIT
  PA3004U - 1 M 06 64 MB MEMORY KIT
  PA3005U - 1 M 12 KIT MEMORY OF 128 MB.

  According to the specification, you can use two 128 MB module.

• iMac 5 k 64 gig RAM?

  OWC offers a concert 64 for the iMac of 5K and application it works perfectly.

  Has anyone tried this before?

  FWIW, I almost did, but at the point where they wanted $1000 + for the kit so I opted for the 32 GB kit. I'm sure 64GB kit works. OWC are certainly reputable.

• Suspect, I have a SGE2010 with faulty RAM, no matter who wants to look at my logs and confirm, or alternative sugest

  Good afternoon all

  I have a 24port SGE2000P and a 48 SGE2010 port.

  My SGE2000P works brilliantly.

  However, my SGE2010 is very bad.  When turned on all the lights of the port rest for awhile.  Then they turn off very briefly and a battery lights before the power clique and it reboots and starts the cycle again.

  I connected it to a cable from the console and reports a variety of decompression errors.

  Most common are: -.

  LZMA: Decompression of file failed!

  HOSTG_rscode_file_load: cannot load the file

  % OS-A-MEMORY: main system memory Pool overflow

  % ERHG-E-SEND: return to the DEFAULT size of the TABLEs

  % ERHG-E-SEND: RSP_INIT: fatal error

  Error fatal file 20d0001.SW loaded error;

  Depending on which firmware the switch is on and which mode (stacking or stand-alone), it is.

  I tried to change the firmware for: -.

  3.0.0.17

  3.0.0.18

  3.0.1.0

  3.0.2.0

  using both Console cable (sigh 25mins) and through TFTP server (on rare occasions I managed to enter).  And I tried the two image of sw 1 and 2 where one of them was defective.

  As all 4 of these use the same firmware start the 2.0.0.03 software, which I don't think is replaced as part of the process of the firmware if it's the same thing.  I thought that perhaps it was corrupted.  I tried to install 2.0.7.5 (I think) who has an older startup software.  But it would not downgrade from 3 to 2 allow me.  And it wouldn't make sense that it runs the software before initialization it unpacks the firmware.

  I managed to get away from the switch upwards in stand-alone mode, maybe twice 80-100 cycles of power.  But when I tried to make a change, he crashed and restarted.

  Finally, I realized if I use my SGE2000P as master of the battery, I could get the SGE2010 to start much more regularly than the unit 3.  Still not 100% but maybe 50% of success.

  If I put as unit 2 seems to power cycle and not go up.

  Also, when I set up the stack the stack Master network cable on the SGE2000P SGE2000P IP it gave errors on the console of the SGE2010 port, but did not restart.

  If I tried to access the master IP SGE2000P Stack WebGui interface, while the cable network plugged on the SGE2010 he crashed and restarted the switch when I entered the admin password.

  My theory about the RAM, it's initialization software runs to put me in the debug console menu.  The firmware is OK, as I have replaced it like 20 times and it's calculated PASS.  When he unpacks the firmware in the memory live there defective segments where the errors to decompress.  And as most of the administration is on the master ones why it can impede the long mode battery.

  Anyone got help, ideas or suggestions?

  I would be really grateful!

  I'm a little at my wits end.

  Hi Ewan, these errors are showing no errors loading and table files. Unless there is a serious component failure through xmodem firmware reload should fix this.

  Since you already xmodem box I would say based on the main system of the pool error, it is probably a failure of a component.

• IMac i7 16 GB of Ram

  Just got a new machine tonight and I was wondering which lot of ram/carrots to give XP?

  He took to 4 GB and 2 hearts now.  What do you think?

  Take a look at choose settings of VM right.  As a general rule, always start with 1 vCPU unless you have an application that can use several CPUS.  (e.g. Photoshop.)  Many times more than 1 vCPU is a waste and can make things slower.

• Cannot increase the RAM in end-15 27 "iMac, retina

  This question drove me crazy.

  End of last year, I bought an iMac 27 "new retina (17.1 model) with 16 GB of RAM of factory. I have since decided to upgrade to 32 GB myself - but apparently not.

  I tried both levels of separate module of Crucial (both sticks 2x8GB, configured by using memory widget Crucial own the latter, so I think it was the 'right' RAM). Both times, after the installation, my iMac would not start. I get the kernel panic, then reboot after reboot goes no further than the Apple logo.

  Conjecturing that it must be a problem with Crucial RAM, I ordered two modules from OWC. This time, I realized an online chat with a Counsellor OWC just to make sure that the triple, I was getting the right modules.

  Result: same kernel panics, same inability to start. After you have uninstalled the aftermarket RAM my iMac works fine.

  And, Yes, I want to install RAM correctly (I did several times with previous computers that are much more difficult to upgrade). I also tried the papillotes in different slots (lots of combinations), switch reset PRAM, etc. etc. Nothing works.

  I wonder... all the stories of 'success' on Amazon and Crucial and OWC come people who completely REPLACE their factory in RAM with spare sticks? Seriously, I think that the issue is an incompatibility with the aftermarket RAM and the factory stuff. On the other hand, I am reluctant to throw 16 GB of perfectly good 'Apple' RAM just to open the four slots for 32 GB OWC.

  I know that Crucial has been (or is still) a provider of RAM to Apple, so this is really surprising.

  It is interesting to try to pick up sticks 'factory' (which will be costly, of course)? I believe that my 'Apple' RAM made by Samsung. Is there a reliable source for this?

  Or I'm doing something completely wrong? (Can't imagine what it would be. I've even been through a chat tech with OWC has nothing to help).

  In fact, I wonder if I now won't be able to max out my RAM (assuming I decide to eBay my Apple sticks and just go all new).

  Difficult for me to believe that the iMac is that picky about RAM...

  Thanks for the ideas.

  I do not have a 2015 end iMac, so I don't know if the problem which arose with iMac 2010 might be similar; before connecting a couple of these very long old threads, most of the problems was: the iMac 27 "would go happily with factory all the RAM, or with less of a mix of OEM and third party RAM (12 GB) max, but would have problems with 16 GB of third party RAM maxed out. I used to have a such 2010 and stayed with a total of 12 GB of RAM (OEM 4 GB and 8 GB of RAM from OWC) worked well.

  Problem with 16 GB on 2010 iMac 27 "i5 & i7.

  Other than the usual suspects such as faulty RAM, RAM slot, or not seated correctly, if you have time, you might want to try to install unless the maximum - it is a shot in the dark, but...

• Can I upgrade an end iMac 2014 with 5 K retina display up to 64 GB RAM?

  Hi, I have an iMac with Retina Display 5 K at the end of 2014. It is maximally in each record except the RAM. I heard that the new iMac end 2015 can manage up to 64GB, despite what Apple has posted on their specifications (32GB). The end of 2014 iMac can also manipulate the 64 GB? My drive is 3 TB Fusion.

  Unfortunately, only the end of 2015 iMac supports 64 GB of RAM. IMac late 2014 can manage up to 32 GB of RAM, but nothing more.
