• New RAM not working not not on iMac 2010

  Hello

  I have a 21.5 ' mid year 2010 i3 iMac, and, after all this time, it was time to upgrade the RAM.

  I bought 2 x 4 GB Patriot SODIMM PC3 - 10600 1333 MHz 204-pin, by following the instructions in the Web page of Apple memory upgrade (install memory in an iMac - Apple Support).: 4 GB RAM SO-DIMM memory DDR3 SDRAM 1333 MHz. I installed it according to job with factory 2x2gb RAM Samsung sticks. After a reboot, everything worked beautifully for about 6 minutes. The identified computer sticks again and showed me a full 12 GB available. Which was great, since Yosemite + a few browser windows and Spotify only lasts up to 3GB. I have enough to spare. However, it restarted and again and again and again.

  I decided to test only the new RAM and started with the combination of Patriot 8 GB. It froze on reboot and fully started once, but it restarted less than 2 minutes later.

  Result: now I'm back to the original combination of 2x2gb. Always deal with the lack of memory and without understanding what's wrong with the new RAM I bought at Fry's. What about compatibility? Is there an another specification? Of course, I know, there may be a malfunction of hardware, but I would like to address this issue before making another run to the store and risking another model or brand.

  For reference: I've tried it before, but because of the lack of information from the seller, I was conquered by a stick of RAM 1x8GB, which is not supported by my model. So I replaced it with the 2 in question.

  Thanks for any help.

  It is generally recommended to stick with quality RAM to buy from a seller that tests and ensures their RAM to work with Macs - the two most recommended are OWC (macsales.com) and Crucial. They both offer helps you determine which RAM you need and offer the lifetime warranty.

  That should be your - sure.

  I'll be back on the RAM for a refund.

  It appears in the BIOS?

  When you install, you did it that RAM modules have been well installed in banks of memory, which means that they clicked in?

• eMachines EL1850 new RAM not working not

  Hello everyone!

  I wanted to upgrade RAM from 2 GB to 4 GB, so I looked at the label placed on the current RAM and tried to find the best match. I bought and tried 1 x 2 GB Kingston and 2 x 2 GB Corsair (more), but unfortunately none of them worked. After installation and turn on the PC, it was a constant noise for a long time and I couldn't do anything. Nothing on the screen. Then I tried one at a time into the two slots with the same result.

  What's wrong? What I am doing wrong?

  Thanks in advance for your time and help!

  The current RAM:

  UNIFOSA 2 GB GDDR3 - 1333 128MX8 1.5V EP, GU512303EP0202

  I tried (all new) RAM:

  Kingston 1 x 2 GB memory DDR3 1333 MHz Non - ECC, CL9, 1.5V, memory unbuffered DIMM (link)

  Corsair 2 x 2 GB memory DDR3 1333 MHz Non - ECC, CL9, 1.5V, memory unbuffered DIMM (link)

  Motherboard: G41T-AD V: 1.0

  BIOS: P01. B3 (the latest version)

  Upgrades successfully achieved to date: replaced Intel Celeron E3400 with Intel Core 2 Duo E8500

  Fortunately, I found someone who was trying to sell the same Unifosa modules, 2 x 2 GB. They work perfectly!

  I want to thank all the people who have tried to help me!

• ProBook 4740 s: new RAM not recognized...?

  I have an old but functional 4740 s Probook, always running on 4 GB of memory. Is no longer worth (especially running programs using a lot of memory as GIMP), and with the upgrade to Win10, I decided it's definitely time to upgrade memory. The max memory for this model is 8 GB.

  According to data IO could find online, I bought Kingston KTH - module X3CS / 4G memory, specified for HP/Compaq. I inserted the memory as far as I can tell, but it does not appear as being recognized. I run the Windows memory checker and found no problem.

  Can anyone suggest what I might hurt?

  Memory module specifications are given as follows:

  Kingston 4 GB DDR3 1600 MHz specific system brand HP SODIMM

  On the Kingston site the Probook s 4740 is not specifically reported as compatible, but they list any of this model. Elsewhere online (IE on thousands of websites of seller) it appears as compatible memory.

  Thanks for any help!

  The most likely cause is that the two modules are not exactly identical.

  It is an essential element of the recommendation that I propose to members who want to upgrade.

  If you want it to run as expected once the new modules are connected, do not mix the types of module or manufacturers.

  Purchase of of another memory identical bar and you shouldn't have problems to start at 8 GB memory acknowledged.

• Compaq Presario C303NR is not completely put on after the new RAM upgrade

  Hello Paul,

  It's Tammy. I finally took the time this morning to upgrade the ram in my laptop, model C303nr. And I am desperate need help because something has gone terribly wrong.

  The laptop starts up to my office, I get nothing but then move lines, a little like snow tv, but more structured. I took the new memory on a couple of times and tried to re-sitting, but I get the same results. Furthermore, when I tried to put the old memory, exactly the same thing happens. Have I completely broke my laptop?

  Can you or anyone out there please help me. This is my first attempt to do something like that and I feel absolutely sick results.

  Clinging to hope for a fix.

  Tammy

  Hi Paul,.

  I must say once again, you have a way very appreciated to bring the balance to my pc problems.

  During my first attempt to install new ram not worked, I thought that I had inadvertently he damaged everything trying to embed. (It is certainly not a room of heap for the maneuver of the ram, clips and fingers! Besides, while trying to stay grounded.) Then, when I couldn't get the old RAM to work either, I thought I had I damaged the laptop everything somehow. It was a horrible feeling.

  Even after that I finally got the new ram to work, I felt bad to not get it in correctly the first time. I felt as if I should have been able to prevent any inconvenience on my part. However, when I read that you have recently encountered a problem with ram of your son, your post made me appreciate that sometimes things happen if its your first time or umpteenth time to do.

  Thank you for giving me the space to hold myself.

  In addition, I can imagine how the ram of your son was stuck. If that does not damage its ram, then maybe ram is a bit more durable than the shell egg-nitroglycerin, I felt... like manipulating its fragility should not always be a concern.

  I wish you the best,

  Tammy

• Satellite Pro 6000 - new RAM does not work

  Hi all

  New to this forum sorry if this was asked before, I did a search but could not find anything so here goes.

  I just bought a new RAM for my Satellite Pro 6000. When I install it nothing happens the laptop won't boot. If I put the old stick in no problem. The ram I bought is unb 512 MB PC133 CL3 and old RAM 256 MB PC133s. I think little small to read with these old eyes.

  I was told I might need an update of the BIOS but cannot find one for my laptop under 1.4 for the moment.
  Any help would be thank Lindsey

  I think that the new RAM is not compatible with the motherboard or laptop.

  The manufacturing of the new RAM you said does not for me so I would buy an another RAM, such as Kingston. Kingston makes high quality RAM and many users here buy Kingston RAM to upgrade its RAM.

  By the way: do you use the RAM or only the new? Normally, if you use two memory modules live, you must use it with the same specifications.

  The update of the BIOS, you can find the Toshiba site, but this doesn t affect the compatibility of Aries.

• Satellite L30 10Y does not start with the new RAM modules

  Hello
  regged just with this forum I have a problem to upgrade memory.

  I read through a few problems of memory here and all users that it is a problem of memory comaptible. I got Hynix 512 MB RAM in my laptop and I bought 2 x 1 GB memory Hynix these two are match sticks to the installed memory, but when I installed my laptop wouldn't boot at all. It would only boot if I had a stick in both.

  I tried to switch ports top and btm and even when a stick was installed it says in XP, Vista and Windows 7 (yes I tried all systems) 896 MB of available space. I even tried to use my other Hynix stick, but he won't start and showed more stick of 1 GB (896 MB usable in Windows 7). After reading all the threads I wonder if it is a hardware failure or is there a fix in the world of Toshiba or perhaps in the world of Toshiba, the L series is almost obsolete and not worth to help people who unwittingly bought their goods.

  I apologize for being slightly down on Toshiba but a laptop that shows what he can work and is not a company should hold his hand up and say that Yes, there is a fault and help deal with the problem.

  You see 896 MB, because the rest is reserved for VRAM for graphics card.

  Sometimes RAM may simply be incompatible, because of incompatibilities of calendar or RAM chip/controller design differences.

• New RAM for Precision Workstation 670 does not

  I just bought 4 of them: http://www.ec.kingston.com/ecom/configurator_new/PartsInfo.asp?ktcpartno=KVR667D2D8P5/2G

  When I install only the new RAM in the computer, it emits a sound when I insert the power supply cord. If I use 2 original 512 MB sticks into sticks new housing 1 and 2 and 2 in slots 3 and 4, the BIOS indicates only 1 GB is installed and the new sticks are not ECC.

  As far as I know, the new RAM I bought has the same specifications as http://shop.crucial.com/1/4/43005-dell-precision-workstation-670-workstation-memory-module.html. I buy the wrong type of RAM? Can I do the computer works with the new RAM (maybe not using ECC)?

  
  

• Satellite A300 - towers, but do not post

  Hello

  I hope that someone has had the experience of a similar question to mine, I have a * Toshiba Satellite A300 * which is a couple of years old, but has been problem free until the last two weeks.

  The question:
  -Laptop turn on but does not post, power tubes, display work etc.
  -Let the battery fully discharged and now the power button for 60 seconds will sometimes allow the laptop to work again, but this work around less frequently works all the time.
  -The problem is the same with or without battery
  -Probably adapter works as the laptop occasionally works and works of battery/power LED

  Why the laptop power it will prevent start from time to time?
  Tips or advice would be great, apparently not a major hardware problem and it certainly doesn't seem to justify a replacement yet.

  Thank you

  Hello

  Hmm... I guess that if only sometimes maybe it's a malfunction of the equipment. If your computer doesn't start it has nothing to do with Windows so it of not a software problem.

  Do you have the hardware upgrades to the last time? Perhaps the new RAM module is not compatible or something else.
  You can see the RAM modules to find errors using Memtest86.

  In the worst cases, the error is related to the motherboard and it is an expensive part of notebook.
  Is your laptop under warranty? Whether an ASP can repair free of charge.

• Tecra S3 - cannot use the new RAM modules in the B slot

  Hi all

  I just bought two RAM modules of 1 GB to replace my old 512 MB one. This, as far as I know, is the maximum allowed by my Toshiba Tecra S3 (PTS30E-01000QSP).

  When I put a module in A slot, the machine works perfectly; If I place a second in location B, the computer tries to start but, at a time given, it freezes just (no activity of the HARD drive or changes on the screen) and the fun begins racing on as if some process crashes in the CPU to heat that make it up. At this point, I was always afraid that the heat can damage the computer and be turned off by pressing the on/off switch, so I can't tell if the problem is solved simply waiting.

  I swapped the two modules on A slot and the two work well when they are the only one on the machine. Pretty funny if I place (as is the case now) has the old 512 MB in the location B as well as a single module of 1 GB in slot, it works!

  My BIOS has been upgraded to the last, that I could find in these same pages (version 3.20 if I'm not mistaken), but it made no difference. If I enter the page of the BIOS when the two 1 GB modules are present, the BIOS recognizes that they are there. This behavior occurs when I try to start Windows or Linux.
  Honestly, I'm puzzled. Someone has an idea what can happen and how I could place the two modules on my machine?

  Thank you very much and sorry for the long post

  O.

  Hello

  The modules you purchased exactly for your Tecra S3? Maybe that they are not compatible with the laptop and it hangs after a few minutes.

  Normally, the Tecra S3 can handle up to 2 GB and that means 1 GB in each slot. For modules of Toshiba part number is PA3411U-1M1G.

  In my opinion you should try it with other modules with original 512 MB module everything works so I guess your new RAM is the cause of this problem.

• Portege R700-19 t - new RAM-> start is no longer

  Hello together,

  so I bought two new RAM sticks for my old laptop
  Toshiba Portege R700-19 t

  But since I installed them, the machine does not start in an operating system more.
  The installed Windows 7 64 bit goes to a black screen before the windows at Startup logo (even in safe mode). And after a few seconds, the fans will quickly but nothing seems to happen.

  The next thing I tried was a (12.04) ubuntu live dvd. But it does not either. No error message or anything, just an automatic restart after a few seconds of black screen.

  The next thing was memtest86 + v4.20:
  It crashes immediately sometimes a black screen and sometimes at this http://i.imgur.com/eJqIyDp.jpg .
  I tested my new two sticks together and alone, still the same problem. The old ones that work perfectly and not crash of memtest.

  In the BIOS is the only thing on the memory and then it sees the correct "Total memory size 8192 MB.

  • Max Speicherausstattung: 8 GB

  In my understanding of both new sticks should work well with my laptop, or am I missing something?

  For me, the question is clear enough; the laptop does not start because of new RAM modules.

  The new RAM modules are not totally compatible, or the RAM modules are defective.

  I recommend you test an other modules; for example modules manufactured by Kingston.

• Module of RAM not recognized on my Satellite Pro A60

  Hello
  I have a Satellite Pro A60 and recently bought a RAM of 512 MB memory upgrade.
  I have fitted on the correct port, however, there does not appear to be be achnoledged as being there.
  Can someone help me?

  [Edited by: admin August 31 05 19:02]

  Hi Robert,.

  I guess your A60 has two RAM ports, then I suggest that Exchange you the two RAM modules autour to check if the port rather than the modules itself that is the source of the problem.

  I hope that you took of anti-static precautions before manipulating the new RAM module. They are easily damaged by a discharge of static electricity.
