New RAM problems?

Hello.
I recently purchased new RAM for my Apple. Since then, my laptop has been freezing up, not responding, and having problems with Safari. I put in the old RAM just to post this topic. Now things are fine!??? I don't understand.? Is this a problem with the chips (512 MB SYNC PC133 SODIMM). I have read that it might be the way I installed the sticks.
I have had to reboot my laptop 5 times an hour before I removed the new sticks and put the old ones back in.
Next... just how much damage have I just done to my Apple?
I installed Tiger last weekend. I have also had some problems with Apps. since then. I really don't understand.
Thanks for your concerns and help.
Scared....

Hi REILLY the NEW GUY,
Sounds like you got a bad stick of ram. Check back where you purchased it and tell them of your problems. They (if reputable) should replace it with ram that is compatible with what you need.

  • New RAM problems with my Dual G4 1.25 MDD

    Howdy I've had my Dual G4 1.25 MDD for 2 years and love it. I got it with 1GB RAM, thinking I was set. For Christmas I wanted to Upgrade the RAM to 2GB. from My PowerMac G4 Manual I knew I needed 2x 512MB PC2700 DDR333 CL2.5 SDRAM DIMM's.
    I went to DealRam (part of DealMac) and found 18004memory.com The price seemed great $39 per stick. I ordered it and within a week got 2x 512MB DIMM's. Problem was it was the Wrong RAM spec. I tried that RAM in my Mac 30 different ways and Everytime the computer either wouldn't boot, or it would suffer Kernel Protection Faults. One time it did boot up but the RAM only recognized as 2x 256MB DIMM's. I called the company, got an RMA and returned the RAM, this time they sent me 2 replacement DIMM's.... for a POWERBOOK, SO-DIMM's. I returned it again and finally Got from them the
    2x 512MB PC2700 DDR333 CL2.5 SDRAM DIMM's. They call it Hyperspeed RAM. Anywho, I powered down let the system cool over night and in the morning, popped it open, put the RAM in the 2 open slots DIMM2/J23 & DIMM3/J20. closed it back up and powered up. Everything was snappier, the boot was quicker and I checked About this Mac, it says 2GB. Apple System Profiler showed all 4 DIMM's and I thought everything was fine.
    Computer ran great for hours, no issues. Everything seemed quicker. Computer went to sleep overnight, next day woke from sleep and Tried to use iTunes and during an extensive sort for Songs, the system Locked up. Nothing would work. Had to force restart. this time I tried to Run my favorite online Game, WoW and after it loaded and I started to play, within 5 mins the whole game locked up. The audio sound went into a sort of Loop, I couldnt force quit and had to force reboot. This happened several times. I finally decided to Run the Apple Hardware Test. The Quick test locked up after running 2mins. I let it sit for 1hr just in case it was still doing something and the progress bar and time never progressed. So i forced reboot, ran Test again this time as Extended test. at 8 min & 31 sec the test stopped and I got an Error Code, this time I wrote it down "2MEM/2/4: DIMM3/J20."
    I guess that DIMM failed. I shutdown, popped open case, and removed DIMM3/J20 leaving the Original 1GB RAM and One of the 512MB Upgrades. I rstarted the Test again and Ran the Extended Test once more. It ran for 27mins & 24 secs and everything passed. So. 1.5GB is better than just 1GB. I powered down and powered back up to try and play WoW. Within 5 mins of loading game to play, everything locked up again.
    So I took both of the new RAM out and left the Original 1GB RAM and ran Test everything was great no Errors. Rebooted, and went onto WoW again and was able to play for several hours. I quit game and shut down for night.
    I have since Tried the 2x 512MB DIMM's in over 10 different variations in the computer with and without the original RAM and everytime I run a high end program or game (WoW, iTunes, and Photoshop), I get lock ups, crashes, and other screen weirdness.
    I dont want to have to Return the Memory again. I am already out over $15 from s/h with RMA's.
    PLEASE Any ideas what to do?
    1 thing I noticed the RAM gets very very hot, when I've powered down tand removed the new RAM. I wonder if there is a cooling issue?
    Anytime I put the Original 1GB RAM in, I dont have problems!

    Hi lz3broc,
    Sounds very much like faulty RAM to me, I'm afraid. I'm not sure about the temperature it's running at, but if the surrounding DIMMs aren't having a problem then I would definitely point the finger at those new memory sticks not being up to scratch.
    If you were convinced it was temperature related then you could always try putting heat spreaders on the memory to help with cooling, but as these stick (semi-permanently) to the RAM then you would never be able to return them.
    My personal opinion is that you should send the RAM back and buy two new DIMMs from Crucial Technology. I only ever buy RAM made by them and I've never had a problem with it - it's the same stuff Apple themselves generally use and works a charm every time. Probably not the news you wanted to hear, but that's probably the only way you're going to get a stable machine with 2GB RAM.
    Hope that helps,
    Andy.

  • New Ram problems with my iMac G5 20' w/iSight

    I purchased a 2 gig stick from (4-all-memory) web sight, got it the other day and installed it. I had removed 512MB stick from that one slot and added the new, it ran smooth for 24 hrs just fine, Then yesterday as I was downloading a couple-a shows from iTunes,(my Mac) it frooze up, had the sound that my Hard drive was making sounded like it was taking a ruff trip up a dirt road, makin all kindsa noise. I pulled the plug as that was the only thing that seemed to work to shut down. I tried to start up after a few, took several minutes to warm, then the noise, no screen etc. I then let the sucker cool down, tried again, same crap. I reversed my up-grade back to my 512MB stick and got everything to work kinda like before. My"About this Mac" button dose a restart kinda thing now when ever I try to see "About this Mac"? It shuts down everything few a second, then all comes back on as if just restarted, but never tells me 'about this mac'?
    Any coments on what to do, ersuggestions. I would like to try the 2Gig stick again, but I am fearful that my iMac might just throw a fit, like me Ex?

    Except for the keyboard & mouse, disconnect all devices from your computer when troubleshooting.
    If you have not already done so:
    Check the RAM install instructions in the manual that came w/your computer to make sure you installed the RAM correctly.
    Boot from your Hardware Test DVD to confirm problem.
    If you have Techtool PRO or Deluxe (make sure both are compatible w/your latest OS System) boot from same.
    If a RAM problem shows up on any of the above, then you should return the RAM to the manufacturer. Hopefully, the RAM you purchased has a lifetime quaranty.

  • MOVED: New RAM Problem

    This topic has been moved to AMD64 ATI/SiS/VIA boards.
    https://forum-en.msi.com/index.php?topic=137824.0

    The K8MM-V supports a maximum of 2GB RAM so it shouldn't be a problem.
    Test each stick with >>Memtest86<< in case one is faulty.
    In the BIOS make sure the RAM voltage matches what is required for the modules. Often, whilst set on auto it doesn't supply enough power. You could also look at setting the timings manually and you should find the correct timings to use on the label on the side of the RAM module.
    Each stick is the same right? You're not using mixed modules?

  • Just installed new ram; problems

    I recently grabbed a 2 gig stick to replace a 512 stick.
    Ran hardware test, everything fine.
    Now, I got a 1 gig stick to replace the other.
    When I turn it on, I get a flashing sleep light and no screen.
    Help!

    You may not have the ram seated properly you have to push it in with some pretty hard pressure. I had this happen the first time I added ram to a macbook.
    From Apple support doc
    "Note: You may need to use increased firm pressure in order to ensure that the memory seats properly. Failure to seat the memory correctly could result in a "no power" situation, or the memory not being recognized by the system."

  • Problem after installing new ram

    Just installed 1 MB of new ram. Everything appears to work with one very annoying problem that never existed prior to installation of ram. The problem is that the window moves slightly with any movement of the mouse. Not a great deal but enough to hide the menu at top of screen. I ran an Apple Hardware Test and all hardware passed. I changed the mouse but no cure. This happens with nothing running so I assume it is not software. It doesn't appear to affect the operation but it tends to make one sea sick with the up and down and side to side motion anytime the mouse is moved.
    Shure would appreciate any help with this.

  • New RAM causes crash problems

    Hello Everybody,
    have some problems with new RAM for my G5. With the original 4 x 256 RAM everything's going fine, but as soon as I correctly stick in the new 2 x 1 GB (Mac Dealer bought), my mac's going crazy (crashes or not being able to install and so on...) Changed the new RAM allready at my Mac Dealer, things remain the same. Does anybody have an idea?

    Have you made sure the RAM is properly seated?
    If it is, contact the Mac dealer and inform them they have a bad batch of RAM.

  • Problems with new RAM

    I bought new ram for my macbook Unibody (7.1) to update from 2gb (2x1Gb) to 4gb (2x2Gb). I replaced the old ram to the new ones, but when I turn the computer on it produces five beeps and continues doing that until I turn it off. But when I put one 1gb old ram in one slot and in the other slot a 2gb new ram it works perfectly and it says that I have 3gb (that means that the computer also recognized the new ram).
    The new ram came from a mac mini, and they are 1333mhrz while the old ones are 1066mhrz, but I heard that when the ram admits more speed than the slot speed they can be used with te speed from the computer (if my macbook has 1066mhrz slots, then, the 1333mhrz ram will work at 1066).
    Can you help me?

    Welcome to Apple Support Communities. We're users here and do not speak for "Apple Inc."
    Macs are notoriously 'picky' about RAM memory timing!
    Although what you suggest about RAM timing might work in SOME computers, your Mac obviously does not work with the 'faster' RAM inserted in both memory slots, hence the black screen and 5 beeps.
    Indeed, some sellers label faster RAM with a slower spec, and indeed some computers don't have a problem with that, but it is not true in this case.
    You have several options:
    1. Go back to the original 2x1GB RAM modules.
    2. Use one of the 2GB with an original 1GB module for a 3GB configuration. It's still a 50% increase in available RAM for your system from 2GB. If you start getting frequent Kernel Panics, that is an indication that the faster 2GB RAM just won't work in your system.
    3. Purchase two of the correct RAM modules with the proper specs. Your Unibody can hold 8GB or even 16GB if you're running OS X 10.7 or newer: http://blog.macsales.com/16302-some-2010-mac-owners-can-get-more-ram-than-they-t hought
    Crucial.com and OtherWorldComputing (www.macsales.com) are two reliable sources for Apple RAM upgrades, guaranteed to work properly.

  • Random restarts and freezes. Just upgraded my RAM trying to diagnose new RAM as the problem but they pass Rember test.

    Hey so I have been dealing with random reboots and computer freezes since upgrading my RAM. I also reinstalled my 10.8.2 at the same time I upgraded my RAM. I have a Mac Mini Mid 2011 with the OWC Data Doubler Kit and a Crucial M4 128GB Boot drive. My computer reboots every 30 minutes or so and sometimes completely freezes up. I am trying to figure out if the new RAM is the issue as I can send them back. I have ran several Rember RAM tests but the computer freezes mid test so I can not see the issue. All other times it completeles the RAM test with no issues.
    Any help is greatly appreciated!

    Reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts on the memory modules when handling them. If necessary, clean them with a mild solvent such as rubbing alcohol.
    The Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.

  • New RAM & UPS problem

    I just installed 8 GB of RAM from OWC. This gives me a total of 10 GB. Ever since, I get warning beeps from my Belkin UPS when I boot up or do a CPU intensive task such as applying a filter in Photoshop. I called OWC and of course they said it's not the new RAM although this never happened prior to the new RAM and started immediately after the install.
    Any thoughts?

    You can find people using smaller VA than what I see as sensible, and I would rather side on safety and not be at even 80%, 1200VA or above is a safe level and price. I went with 1500VA, in part because it was 1000VA or this, and so I could easily add a battery pack for 1 hr run time.

  • Problems installing new RAM

    Hi guys,
    I have a 17" G5 imac (built in isight) i recently bought a 2gb RAM chip for it. I have tried to carefully follow the instructions to install it, but the chip does not seem to "click" into place as suggested in the manual and if i close the machine up again the new RAM is not recegnised. So, my question is, am i being too gentle with the chip? or is there some special trick to this? i installed ram on my macbook easy enough before however this attempt is proving difficult. anysuggestions would be really appreciated.

  • Intel iMac randomly relaunching Finder. RAM problem?

    Several months ago I bought a new 3.06 GHz Intel iMac with 2GB of RAM. I also bought CS4 so I maxed out my RAM at 4GB with a 2x2GB RAM kit from Other World Computing.
    I've noticed in the lately that everything will suddenly hang, the Dock won't appear when I cursor to the bottom, and then my desktop pic will change. I have my prefs set to choose a random one each day but this isn't happening at the right time, it's random. Not only that but if I open Dashboard after that it has to reload all of my widgets again. Plus any docked Finder or app windows pop back out to the desktop. It's like the Finder is being relaunched or something.
    I'm wondering if this could be an issue with bad RAM or not having enough. With email, browser, FTP, time logger, and a few smaller apps going I can never really have more than a couple of the CS4 apps open without things getting sluggish. I try to avoid having more than 2 open at any one time. I've even dropped Photoshop's RAM usage settings from 70% to 60% to see if it makes any difference.
    The problem is still happening and it seems to be happening more frequently. Things just relaunched and I went into Mail to minimize an email window. As soon as I clicked the yellow button things hanged again but not in the same way. No windows would minimize, the Dock wouldn't appear and I couldn't switch Spaces. When I went to restart, as soon as my cursor rolled over the Dock item in the Apple menu it stalled there for a short time before I was able to go down to restart. Then the restart sequence stalled and I had to force a shut down.
    This is really frustrating as I was expecting a great new machine and software to replace my aging PowerMac G4 and older apps. Is there a way to test for bad RAM or does this sound like a known issue with CS4 or iMacs in general? I don't have the original 2x1GB RAM sticks any more, I sold them after installing my new RAM.
    Any help would be greatly appreciated.

    I've been trying a few things here and there when I've had time, giving time in between to see if the problem reoccurs. So far I've done the following:
    1. Repaired Permissions. No effect.
    2. Used Onyx to clean the System, User and Font cache options listed by default. It also told me that S.M.A.R.T., startup volume, Permissions and Prefs are all ok. No effect.
    3. I removed the RAM, inspected the boards and the slots. Can't see any sort of damage to either. I replaced the boards but swapped slots. Both boards are firmly seated. Also no effect.
    I'm going to try running 1 board at a time, swapping slots if the problem continues. If it does I'll try creating a 2nd admin account and go from there.
    I've also noticed at times when the hang happens it seems to be when I click on an item in my Dock (usually a folder of items). There have also been times that after it happens I'll switch to another space and the windows for different apps will have disappeared. The apps are still open but if I try choosing the missing window under View or Window they still won't appear. Same goes with trying to use Show All under the Finder menu.

  • Help! Installed new RAM and now screen isn't coming on!

    Hi
    I'm in a bit of a mess and would be grateful for any help with this one:
    I have a Powerbook G3 500mhz Pismo that currently has a 512mb card in the top slot (Kingston PB100/512) that I installed about two years ago with no problems and an original 128mb in the bottom. At Christmas I bought another 512mb for the bottom slot – (Kingston KTA-PBG4/512 - This one is smaller than the first but it was the one reccomended by Kingston on their website for the Pismo).
    I have just got round to installing it after backing up my system and I have good instructions on how to do it (I have replaced the HD two years previous with no problems)
    Firstly I have to mention that just before I changed the RAM the laptop fell from a small stool (about 1.5feet high) onto carpet due to the unbalancing effect of taking out the battery/CD ROM. It landed on its edge where the power socket is. I immediately put it back together and turned it on to make sure it was ok - it came on fine and there were no problems visually, mechanically or otherwise, so I carried on with the installation.
    I installed the new 512mb card in the bottom slot and re-assembled but when I turned it on the screen remained black! From the computer itself, however, it sounded as if it had started up ok – there was the chime and the familiar sound of the hard drive at start up.
    To troubleshoot I removed the new RAM card and put back the old RAM as it was – this made no difference. I checked to see if the processor board was firmly in place or if I had dislodged any connectors by mistake within the area that I had worked but this made no difference. I also tried to re-set the parameter RAM and this made no difference.
    Because the laptop took a small knock prior to installation, I am not sure if that has caused something to come loose or damage of some kind but as I mentioned I did test it immediately and it worked, so it’s either a delayed reaction or the new RAM card has caused it. – (As mentioned there is a difference between the two 512 cards in both name and size but the smaller size of the newer one I assume just reflects advancement in technology and it was reccomended by Kingston!)
    If anybody has any advice on this I would be very grateful (and also, if anybody can point me in the direction of instructions on how to take the pismo apart to get to the connections to the screen that would be great – in case I have to do it)
    Many Thanks Barry

    SpottyFox,
    It sounds like you are properly seating the CPU card from your description, so I don't believe that is your problem. I am glad you checked the pins (I should have mentioned that as the next step if the reseating did not help). I cannot answer whether anything was damaged from your description of the pins; I have read where others have realigned bent pins with success so maybe your mileage will vary.
    Start up your Pismo, then shine a flashlight directly into the display; if you can see data being written to the display, just the backlight is refusing to light. If this is the case, check the inverter board connections. The inverter is under the clutch cover and powers the fluorescent backlight in the display. Enlarge the bottom picture in this link to see the inverter:
    http://www.ifixit.com/Guide/Mac/PowerBook-G3-Pismo/Inverter-Page-10-Inverter
    Check connections at each end of the inverter. Disassembly is not as extensive as this guide suggests. Support the back of the display, then remove the main battery, optical drive, lay the keyboard on its face on the palm rest, heat shield, and clutch cover...that's it.

    You might also connect the Pismo to an external display; failure here would suggest a more serious problem.

  • Kernel Panic Message...Caused by new RAM???

    Hey guys, just purchased 2x1gb ram from otherworldcomputing.com for my powerbook G4, im currently running the latest version I can possibly run which is 10.5.8  Everything seemed great when I put the RAM in, seemed like my computer was running pretty fast campared to the 512gb that came with the computer.  All of a sudden, while im searching the web, it throws that kernel panic message up at me.  I restarted and a few minutes later while im still on the web, bam, the same message. 
    I am currently in safe mode while Im writing this and nothing has happened yet(update:a few mintues after I finished typing this thread I received the same message, I have turned the computer off and jumped on my wiftes computer to type this I am thinking about putting the original 512mg ram back in to see if I get the message again) 
    Wierd, the first few days witht the new RAM everything seemed fine and then all of a sudden I got those messages.  I have never had the problem ever before so it makes sense that its gotta be the new RAM right?  Here are my specs

    To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
    Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.

  • My new RAM doesn't work with my iMac.

    Hello,
    I bought new RAM 4GB PC10600 DDR3 1333MHz SO-DIMM to installed in my iMac 3.4 GHz intel core i7, osx lion.
    I try to installed it alone without original RAM (2GB * 2 pcs) installed to check how it works.
    After press start button, there are 3 beep sounds and iMac won't start.
    I try to reset PRAM follow the instruction, but it won't work.  Because there are 3 beep sounds alarm immediately after press start.
    Does my RAM have a problem?

    My iMac has 4 memory slots and I try to installed one by leave 3 slots empty.
    By the way this is the 2nd ram I purchased from OWC with same spec as the last one (also same as link above) but different in purchase date (about 2 weeks different).
    So now I have 2 GB *2 pcs (come with iMac) and 4GB * 2 pcs from OWC.
    So I'm quit sure that this ram is compatible with my iMac because the first one is work.
    But I have some notice,
    For the 1st RAM I bought from OWC (4GB PC10600 DDR3 1333MHz SO-DIMM), when first installation it also didn't work. I can't start iMac. And after 2 weeks, I try to installed it to my iMac again, now it can operate as normal.  What do you think about it?
