What happens if RAM is BAD?

Hello all, My wife and I are planning on purchasing a PowerMac Quad. And I am definitley going to add RAM to it! Just wondering, what would happen if I install a bad RAM or a RAM that is not compatible? Thank you in advance! -Ray

All kinds of bad things can happen if you have bad RAM ranging from non recognition to crashing your system. I would suggest making sure that you check with the vendor on matching RAM you are interested in to insure the sticks you are purchasing will work with your system. Most reputable vendors will have a web page that allows you to id your system and then select RAM that is a match. And also look for replacement guarantees. On another note, RAM installed by Apple with your purchase is generally more expensive than buying from another vendor and installing yourself.

  • Ram gone bad?

    does 3 beaps and black screen, nothing happening, mean ram gonw bad??

    The products are made in China!
    Quality control is still better than many, but I have noticed a rather higher percentage of reported faults on the forums over the last year than previously.
    Replacing RAM doesn't affect anything on your Hard Drive, in fact the RAM is user-replaceable (about the only thing that is nowadays).
    Nevertheless, If it were me I'd be happier if I had a backup on an external HD.

  • What happens to undeliverable APEX_MAIL?

    Anyone know what happens to undeliverable email (bad email address for example) sent thru APEX_MAIL?
    Does the "undeliverable" email show up in the "From" inbox or does it just disappear?
    Thanks,
    Russ

    Helpful... Thanks.
    I queried the tables and found the queue empty (good) and the log shows my outbound email (to a bad email address) without any value in the MAIL_SEND_ERROR.
    Yet the email has not bounced back anywhere I can see... The "MAIL_FROM" is a valid email address (via gmail) so I had hoped a failed delivery message would show up in the MAIL_FROM inbox, but it has been 3 hours and nothing yet.
    FYI, my "MAIL_TO" is an invalid email recipient at a valid domain. Next I will try a bogus domain.
    Any thoughts?

  • What happens if I intall 8gb of RAM when the max is 4?

    what happens if I install 8gb of RAM when the max is 4?

    It depends on the model of MacBook you have; click here, append the last three characters of its serial number to http://www.everymac.com/ultimate-mac-lookup/?search_keywords= , load the page, and check the actual RAM limit.
    If it's listed as 6GB and 8GB is installed in it, the computer will slow down to the point of unusability once more than 4GB is in use.

  • Macbook Pro frozen with a strange sound every 5 seconds. What happened?

    I was just surfing the net and suddenly my macbook pro 13 got frozen with a loud "beep" every few seconds (the same sound as that of upgrade booting). What happened? I've shut down and then it restarted as usual.
    Sorry for my english.

    Sounds like bad RAM. Run a hardware check and/or take the machine to the Apple Store or AASP.

  • What happens to FPGA code when a module it expects is missing?

    Hi Folks,
    I want to know what happens if you have FPGA code that expects a module to be present running on a system where the module is missing.
    We have a RT control system that runs on a cRIO 9014 with a 9111 backplane. There are only two modules in the slots and one of these is the Prosoft Profibus module. The biggest chunk of the FPGA code is taken up with configuring and sending and receiving using this module. Specifically the communications with the module are done by the Read (Memory) and Write (Memory) structures.
    We are developing code to use the Ethernet/IP libraries instead of Profibus in some cases. This means the communications moves from the FPGA to the RT. We are considering have the ability to switch be an option.
    My concern is that if the FPGA has code in that references the Profibus module, then it might behave badly if the module is not present.
    And so my question is if FPGA code tries to reference a module that is not present, what happens? Is it just an error? Will there be no error? What?
    Thanks!

    I am not familiar with profibus, but why not just remove the module and run it and see what happens? I'm guessing you will get an error, althougth which error I am not sure.

  • Hyper-V host crash and live migration - what happens?

    Hello there,
    it would be great if you could help me understand how live migrationworks on a sudden host crash of a cluster node.
    I know that the cluster functionality mounts the vhd file on another host and runs the VM.
    But what happens to the VM itself? Does it crash too and is simply restarted on another host?
    To my knowledge the RAM of the VM is run in the RAM of the host, wo I would assume that is all lost on a host crash?
    Thanks for any help understanding this,
    Best regards, Marcus

    In a sudden crash, there is no time for the state of any running VMs to move to another system.  Therefore, the VM is restarted on another node of the cluster.  Think of the host crashing as being the same as pulling the power cable on the VM.

  • Cannot Sign in to Ebay ONLY problems, cache, cookies, firewall, what happened???

    Hi and thanks in advance for anyone who can help with any suggestions. I downloaded the new version of firefox a few weeks back. The next day I noticed I could not sign in to my Ebay account. I can go anywhere else on the internet and all my sign in/passwords all work fine, only having problems with ebay. I can go on ebay but when I try to actually sign in it says ..
    Secure Connection Failed
    The connection to signin.ebay.com was interrupted while the page was loading.
    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
    Please contact the website owners to inform them of this problem.
    I have been trying for weeks and still cannot get sign in.....it is only happening on my DESKTOP....I can sign in on my phone and on my tablet....also on my sons HP laptop or his HP desktop. I'ts only on my desktop ....I have tried the firewalls. I reregistered and made a new account but once I signed out it won't let me sign in to that one either. I can go anywhere on ebay and click like "security or answer center' and it takes me there, as long as I do not click on the "sign in" part.....I have done so much to fix this in the last few weeks but nothing works.....I don't know what to do....somthing has to be wrong or something got deleted.....firefox is no help because everything on their help page is not working....Please if someone could give me some idea of what happened I would be so grateful!!

    Renegadewoman, welcome to the forum.
    The first thing that I would do is try another browser, i.e. Internet Explorer.  If your password doesn't work in it, I suggest contacting Ebay Customer Service.  This is most likely a software problem; not a hardware problem.

  • What happened to ability to upload to ovi share fr...

    as the subject says?
    Recently got the m8. And on my older 5800 (piece of garbage) i was able to upload my photo to my ovi share account right after i took it, or from the gallery. And i was able to create new upload content to flickr and ovi share from an application called share that was a Rom application on most my previous symbian phones back to n95.
    What happened to share application? The social app is a joke. Only has ability to use twitter and facebook, and very poorly to i might add. Why can't we make flickr and ovi profiles like we used to? Or better still, where the hell is the ovi share app gone? :mad:
    i dont want to post my photos on facebook or twitter, I've been using ovi share to store all my photos and some video's and lots of ringtones since it started.
    I need the ovi share app back. I need to be able to upload my photo to my ovi share account when i take it or from my gallery, not facebook or twitter,
    used to be so great. Simple photo storage with one click. Even used to upload in the background so you can carry on taking photos.
    This n8 dissapoints more and more every day. Nokia are failing. Nokia are getting owned by a company that don't know anything at all about phones. I talk of apple of course with there iphone. Apple created a flawless facebook app. And a flawless youtube app. And even an incredibly fast flawless web browser based on the exact same source code as Nokia very poor attempt on m8. Safari web kit i talk about. What the hell is up with that? Nokia been in the mobile phone industry since the start. Dam they made them as popular as they are today. But now they have sold out and getting whiped by apple.
    Anyway. Give me ovi share application for n8 please to start with. Then try and make a youtube app on par with the iphone's. Then try making facebook app that is as good or better than iphone. And most important thing of all, make a web browser that people can use. This n8 browser is exactly same as one on my 5800. Only the 5800 version worked. So many bad things on n8. Hope they are working on those things I've mentioned or i could be cutting my sim card down to size to use in my iphone4 permanatly.

    Nothing happened to File Sharing but the appearance of iTunes has changed. It confused me at first also. Here's how to do it.
    Are you looking in the right place to find the shared files on your Mac?
    First thing you need to do is on your iPad. Share the files you want to transfer by selecting Share > iTunes.
    Start iTunes on your Mac. Is it iTunes 11? If so use the View menu in iTunes to select View Sidebar.
    Then connect your iPad to your Mac.
    Select your iPad in the left sidebar.
    Select Apps in the row of tabs in the right window of iTunes.
    Scroll down under Apps to the File Sharing section. It is below the complete list of apps.
    You should see a list of the shared files or a folder that contains the files. Use the Copy To... Button ( if there is one ) to copy the shared files to your Mac.
    The problem I had originally was the scrolling. There are two windows of apps. Each window can scroll within its own window. So scrolling n the tp window of apps will get you to the bottom of that window but not down to the next section which is the file sharing area. Scroll by using the outer most scroll bar if you have one or if in Mountain Lion place the cursor near the left edge of the apps area to scroll to the lower File Sharing area.

  • Last night, mail suddenly lost all my emails, which were stored in mailboxes.  What happened and how can I find my lost files?  I have the latest MacBookPro, running Lion 10.7.2 all software updates installed

    Last night the mail application from Apple lost all my old emails, which were stored in mailboxes, neatly sorted by category.  What happened and how do I find them? 
    Details:  I shut down mail to run errands outside my office.  My late model MacBook Pro was on "sleep".  When I returned, I opened the application, and (RATS!) all the mailboxes were missing.  They just evaporated. 
    Operating system:  10.7.2 - all software updates installed and current as of 24 hours ago (12-30-11, 6 AM EST). 
    ln the mail program, the trash folder is OK and the sent folder is OK. 
    Yesterday, I did no maintenance on my mail folders.
    HELP! 

    1 - the sudden disappearance of my 22 mailboxes, used to sort the emails that I need to file for future use
    That was most likely the result of some kind of corruption, as I've already said, not a bug in Mail.  Have you repaired the hard drive with Disk Utility recently?  That wouldn't be a bad idea.
    2 - at random times, mail (or the server) says that my password is incorrect and I must reenter (fix:  usually I can quit mail, restart, and the connection is restored without reentering my password)
    This is a known issue, where a failure to respond promptly on the server's end mimics what happens when the password is rejected.  There's no need to quit Mail, just cancel when asked to enter the password, take the account back online and try again.
    3 - mail seems to resort the mail in my mailboxes at random time.  Several times a day, I must reset the sort to (a) by date; (b) by desending
    Never seen that before.  That points more to some kind of possible corruption in your Mail data or preference files.

  • What happened to toDo's in Mail

    What happened to ToDo's in mail? I used to be able to create a ToDo from a mail message I have not found a way to do that with the upgrade to Lion.

    Hi, NO_PC.  I missed the to-do box on Mail also, but I played with Mail and iCal till I found how to do it.  I checked with Apple Express to be sure this was the way to do it.
    In Mail, mouse over the header until you see the grab hand.  Drag it to iCal and drop it into the events column.  Then, grab the event and drop it in the Reminders column.  It will make a reminder but careful! cuz both event and reminder will be in focus.  If you delete the event, you'll delete the reminder too unless you first click in white space (or esc) to remove focus.  Then click on the event and delete.
    Open the reminder and you'll see the URL box says "Show in Mail" so you can refer back to the original email.  If you "archive" the message it'll just stay in the archive mailbox till you're done with it.
    I explained this in another section, if you want to read that (at the bottom):

  • I've upgraded to mountain lion and now cannot use microsoft office--what happened?

    I've upgraded to ox Mountain Lion and now cannot use any of my Microsoft office software.  What happened?

    It appears that you upgraded your computer to Mountain Lion and were using Microsoft Office 2004.  In the short term, if you need to open and modify Word files, go to the file in the Finder and Control-Click on it.  A menu will come up: go to Open With... and select TextEdit.  This should allow you to open, modify and save the file for the short term.
    You can do the same trick to open Microsoft Excel files in Preview and print them; but I do not think you can modify them in this way.
    Workarounds for Microsoft Office 2004 since upgrading to Mountain Lion:
    1.  Upgrade to Microsoft Office 2011.  This version works in Mountain Lion.  However some of your legacy 2004 files may convert badly.
    2.  Restore the version of OS X that you were using before Mountain Lion.
    3.  Partition your hard drive and/or attach an external hard drive and install Snow Leopard on it and use the 'dual-boot' method of booting into Mountain Lion when you need it and booting into Snow Leopard when you need to run your PowerPC applications such as Microsoft Office 2004.
    4.  The method I use, which allows me to run my PowerPC applications concurrently with Lion:  I installed Snow Leopard (with Rosetta) into Parallels 7 in Lion:
