After ram upgrade, continuous beeps, but then boots ok?

I just upgraded my ram to 2 x 4 GB 1067mhz DDR ram. The brand is Corsair. Further details here: http://www.ebuyer.com/164771-corsair-4gb-ddr3-1066mhz-laptop-memory-cm3x4gsd1066. I purchased this ram for my macbook pro mid-2010. The comments in the link indicate it should work with my macbook.
Unfortunately - and I think it's to do with the ram - when I turn the power button, I get continuous beeps. But weirdly after holding down the power button (off), letting it go, and then turning on again a few times, the MBP will eventually boot up fine. Doing a 'system report' indicates the ram is operating 'OK'. Although I'm a bit skeptical about that!
I thought the ram might not be installed properly so I pulled it out and pushed it back in again. But still the same problem.
I think it's really odd that the MBP will eventually boot up, so I'm not 100% sure it's the ram.
Does anyone have any ideas how to fix this?

So-called value RAM like Corsairs value line or Kingstons value line are often problematic in Apple machines. Apple tends to set its design standards quite tight in terms of RAM for things like clock timing, latency and so forth.
"Value" RAM lines are in fact the exact same modules as used in companies better, machine-specific or configuration-guaranteed modules, but the value RAM failed the stringency QC testing required to make the higher level product cutoff.
All RAM tends to start out the same, and then the level of quality specificity or guarantee is based on various QC testing - the "good" stuff that places like Crucial or Kingston or OWC sell as system-specific passed or exceed all QC test limits as specified by the computer manufacturer. The value or non-system specific stuff is the stuff that did not make the grade for the higher QC standards (but it still may be okay in a system that allows sloppier specs than a higher end system like an Apple logic board's requirements).

If the reset doesn't work, force the iPad into Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button.
5. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: You need to be patient and repeat the above many times to recover your iPad. Data will be lost.

I am experiencing difficulties opening some web-based PDF files on my iPad. I was having the same difficulty opening the same PDFs on my iMac (after I upgrade to Yosemite) but was able to overcome it by adjusting the Adobe Reader plug-in settings.

I am experiencing difficulty opening some web-based PDF documents on my iPad. I had exactly the same difficulty on my iMac (after I upgraded to Yosemite) but was able to overcome it by adjusting the Adobe Reader plug-in security settings in Safari (in OSX).
Unfortunately there does not seem to be a way to similarity adjust the security settings in Safari in iOS 8.
The message I get when I attempt to open the PDF (on my iPad) is as follows:
            "To view the full contents of this document you need a later version of PDF viewer. You can upgrade to the latest version of Adobe Reader from ..."
Needless to say this is unhelpful for two reasons:
- I have the very latest version of Adobe Reader; and
- in iOS Adobe Reader is not a plug-in and plays absolutely no role in opening web-based PDF documents.
If anyone has experienced this difficulty and has been able to overcome it I would be most appreciative to hear of you solution.

Mac mini won't boot after RAM upgrade.

Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?

Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.

MacBook not booting after RAM upgrade

I'm sorry if the case has been already posted.
Yesterday I took my MacBook Alu unibody late 2008 to a RAM upgrade (from 2 to 4gigs) to an offical Mac Reseller. They installed it and showed me that the system loads properly and recognized the new RAM.
I took it home, started working on After Effects and Photoshop and when i wanted to check a video on Quicktime, this program refused to boot.
Then photoshop freeze and after effects did so. I quited all aplications and restarted. On restart after the 'bong' i've got the grey screen white an apple logo and a loading bar underneath, that was it, it never finished loading but shutting down.
After the 2nd try the computer gave me the BAD RAM alarm signal right before the start button was pressed and nothing more. I just managed to start it ONCE on safe mode, but this one also freezed and colapsed.
Today i didn't get the BAD ram alarm but the grey screen and loading bar after shutting down.
I took it back to the reseler, the shop boss who did the upgrade wasn't there , the guys on the morning shift placed the old RAM back resulting the same. So they told me it's a software problem, not hardware and might be caused by a failed firmware update or something i did wrong and since i was showed that the system booted after the upgrade i can't complain or argue that they did somethiing wrong.
So basically the want 80euros to check what's wrong with my computer plus the 120 i already payed them for a RAM that doesn't work and of course the repair cost of the computer.
On monday i'll go to talk to the boss, what do you guys recomend me to tell him? i'm frustrated that the guys there treat me like if i broke my computer for beeing stupid and wanted to get it fixed for free, when it clearly broke after they did something wrong on it!
please advice me!
thanks!

What brand is the RAM? From what you said, it is obvious that the RAM is at fault. I would simply tell them that it is not compatible and return the RAM.
Check the System Profiler to see what it says about the RAM (Apple Logo - About this Mac - More Info) and run this application to test the RAM:
http://www.memtestosx.org/joomla/index.php
If either shows any errors, print out the results and take them with you to the store.

MacBook Pro won't boot after ram upgrade...

Hey everybody! Hope everyone is having a great Christmas! I got a 16gb ram upgrade for my 2012 MacBook Pro 15 today and I am having some trouble with the upgrade. Its an odd problem. I installed the two 8gb sticks no problem, but when I try and boot into OS X the machine shows the apple logo with the spinning wheel underneath, and then it just shuts itself off. I don't know what the problem is. The machine boots fine into my Windows 7 partition, and registers both sticks of ram. OS X restore also boots no problem and lets me reinstall OS X, which is what I am doing currently. IDK if this is just because of a hardare change or what. The ram I installed is Adata pc3 12800 1600mhz ram, so it should be supported.

Replace the Ram, buy from OWC or Crucial, buy the Ram Apple recommend, don't rely on "it should work"

Re: Satellite A660 - No boot after RAM upgrade

I have just gotten 8GB of RAM for my Satellite A660, it is Corsair CM3X4GSD1066 4GB PC-8500 (1066MHz) 204-pin SO-DIMM DDR3 RAM CL7.
The system posts fine and the 8GB is showing up in BIOS but once its clears post and goes to load Windows it stops on the black screen, the cursor flashes a few times then it stops. I have left it for about 5 minutes and it wont boot through.
Please Help.
I have replaced the 4GB sticks and it works fine.

Hello
For me it sounds like that the modules are not compatible or have defective sectors
As Akuma wrote, such performance modules are risky in notebook because you dont have any options to change the latency values as on desktop computers. So I always prefer Kingston modules for notebook RAM upgrade.
But before you buy other modules, try a BIOS update and load the default settings.

Macbook Pro is Not Booting After RAM Upgrade

Hi,
I just upgraded the RAM in my MacBook Pro running Mountain Lion from 4gb to 8gb (Using the memory that the guy at Fry's recommended). It has been stuck on the Apple logo for about 20 minutes after the upgrade, even after I made sure that the RAM was seated properly. Is it normal for it to take this long to boot after a RAM upgrade?

I installed 8gb (2 X4gb) and it has a maximum of 8gb. I have determined that it was just bad RAM, so I will return it as soon as I can.
Thanks.

Apple Hadrware Test never ends after ram upgrade

Hello,
I have a macbook pro 15" mid 2012 (not the retina) with osx 10.9.4.
I recently upgrade my 4go of ram to 8go of ram (Corsair Vengeance SODIMM 2x4go PC12800 1600Mhz CL9 1.5V CMSX8GX3M2A1600C9).
In order to test the ram I use the Appel Hardware Test.
Both mode, simple and extended, seems to be frozen and never ends.
I try to let the test works the all night and the all day but the test never ends.
So I decided to test my ram with memtest86 boot cd and everything seems to be ok.
The fact that Apple Hardware Test never ends trouble me.
Do you think there is a problem with my ram ?
Do I need to return my ram ?
Thanks

Welcome to the Apple discussions.
We could discuss how you'd benefit from the additional memory, however, since the system isn't working, let's focus on the beeps.
When you start the system, it goes through some tests (called the power on self test or POST) before loading the operating system. If it finds any errors, it beeps, and the beeps are:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
3 beeps means it doesn't find any memory that passes the POST test. The fact that this started up after the service center installed the memory upgrade is suspicious, however, if it worked in the store then stopped working later, it may just be unfortunate timing.
There are some company's on the internet that claim they can repair the logic boards, otherwise, Apple's solution is to replace them. In the US, some Apple stores offer a 'fix everything' service for $350, which is less than specifically replacing the logic board - perhaps there is a similar service in Taiwan.

Powerbook G4 17" motherborard failure after RAM upgrade???

Thank you in advance for any advice.
I have an original, first generation PB G4 17" that I've used for 5 years. Recently, I had to replace the AC supply because the former one was bent when the laptop fell out of a chair. When I took it in to an authorized dealer here in Taiwan, to test the power adapter, I decided to upgrade the RAM from 1GB to 2 GB. Before I brought it home, it seemed to work at the store, although I thought I did not appreciate any performance boost when I opened multiple apps. Anyway, after I got home, I tried to turn it on, but it would not turn on. Thinking the battery was depleted, I hooked it up to the new AC adapter (Apple brand), and lo and behold it would not boot. I would shut it down by pressing the on/off button or just disconnect the power source (adapter and battery). It started to beep three times after multiple attempts. I took it back to the store, and got my original RAM reinstalled, and the same three beeps occured. I just got a call from the service center and was told that the motherboard has failed. Does any of this make sense? I have never had any trouble like this prior to the RAM upgrade. I just replaced the HD about 6 months ago. I'm just sick to my stomach...Any suggestions? Any input would be much appreciated.

U410 incredible slow after RAM upgrade

Hello everyone, A month ago I bought a Lenovo Ideapad u410 MAG6NMH and decided to upgrade the memory from 8GB(2 sticks of 4gb) to 16GB (2 stick of 8GB) . but after I had change the memory my notebook became very very very slow, like starting up took 8 minutes. So after some research with google I though the settings in my BIOS are wrong, but I was not able to find my RAM/memory settings in the BIOS, did I overlook this? Some of the specs from notebook/memory: CPU/SoCCi7-3517UCPU architectuurIntel Ivy BridgeThe processor should be able to handle16GB RAM memory Memory information(To show my old and my new memory I have put them both in (new 8gb stick and old 4gb stick), when my pc was slow both the 8GB stick were in) the old 4GB RAM specs: new 8gb RAM specs: My BIOS version: Picture from one of the new 8GB memory sticks: I hope I have informed enough about my specs, I hope some of you guys can help. And again , my notebook was slow with two stick of 8GB(so when I had 16GB) but for the pictures and installing cpu-z I replaced one 8GB stick with an old 4GB stick. I hope I've been clear enough en sorry for my bad English. Mod Comment: Removed blank spaces that should have included pictures. Please see About-Posting-Pictures-In-The-ForumsThanks, I've edit it.

I too am having this problem with my i5 U410 after upgrading from 6gb of ram, to 2 x 8gb corsair vengeance ram! I've had slow boot times, CPU usage darting all over the place and makes my laptop unusable! I've been troubleshooting this all day and have found that If I remove 1 x 8gb stick, laptop runs completely fine. I then bumped into this thread (https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Betreff-100-CPU-load-with-16GB-RAM-eGPU/td-p/1219312) for a different lenovo laptop, which mentions about the bios not being able to allocate enough memory for 16gb of ram, plus a GPU over 512mb, which the U410 has a 1gb GPU. So I went into the bios and disable the Nvidia graphics driver and set it to UMA only, and low and behold, the laptop runs completely fine with 16gb of ram installed. But this disables the GPU, and as a video editor, this is not a tradeoff I can deal with. I've trawled the intenret for hours not looking for a solution, but havn't found any reasonable explanation yet!

KT3v MS6712 System Won't power up after RAM upgrade

hello this is my first posting to this forum and I hope someone might be able to help on this as I am totally stumped. I have been running my KT3V MS6712 mobo with 256MB since it was built. The manual for this mobo says it can handle up to 3GB RAM in any order or size. I have 3 DIMM slots and thought it would be more cost effective to just
purchase 1 DIMM leaving the other 2 slots free. So I decided to upgrade to 1GB and I bought a Kingston 1Gb PC2100 266MHz DIMM and installed it on my system. Now my system won't power on at all. When I press the power button on the PC, the CPU fan spins for like 1-2 seconds then stops. The system appears to be completely dead. Cos I thought the problem was down to the new RAM installation I thought better put my old 256 DIMM back, however I still get the same problem. I have tried swopping both DIMMS into different slots but still doesn't work. The system was working fine until I did the RAM upgrade. I tried resetting the CMOS by moving the jumpers around in case it was a BIOS issue, still hasn't made a difference. Dunno if its the PSU which has suddenly gone, however seems strange. There are no beeps from the system or lights flashing to indicate anything. I don't have
the D-Bracket installed either. I have also never upgraded the BIOS on this system as it has always been stable. The CPU is not overclocked. Has anyone had this problem before after a RAM upgrade? Hope I have given you enough information

Suntek is perhaps not the best of PSU makers, but a sudden collapse is not so common. You normally notice problems earlier.
I took a big beating last time I said this , but it is important that there is no power in the system when changing memory sticks.
It sounds a bit like the processor went away for holiday. Have you any data on the processor temperature? Is there any activity at all? Does the processor heat sink get warm?

Unstable Mac Mini 2011 after ram upgrade

I put in 8GB kit ram from Corsair. Every specific things is matching with Apple's requirement on ram upgrade. I got Corsair 8GB KIT DDR3 SO-DIMM, 1333Mhz. The first boot with the new ram was fine but after 10 minutes of normal using (Safari, Spotify) and testing open Photoshop CS5 it crashed.
I shut down the system and tried to take off the rams the put it in again just to make sure that they're there perfectly. Second boot, everythings seems work well but after a while, maybe 20 minutes, Safari crashed and a "crash log" is sending to Apple. Happened the same with Spotify, Photoshop when it was open. I couldn't reopen the programs so I did another reboot.
The third reboot, seems fine until 1h30min the whole system crashed, the computer is rebooting by itself and showing a message of "something is wrong with the system" so it needed a reboot.
And Safari crashed once again while I wrote this.
I hope someone can help me solve the problem. I'm running the lastest version of Lion Mountain (10.8.2), 2.5Ghz i5 mid 2011 Mac mini.

I have used Corsair RAMs on multiple Macs with
a lot of success (running a 16 gig on a 2011 Mini Server
I am currently typing this on). It may just be you got a bad
one. It happens. Depending on where you purchased
it should be no issue replacing.
You should check though to see which is bad. Put
both of the old RAM in to make sure things still work
as before. It is possible something else may be wrong.
If all is well, then swap out with one new module at a
time and see how it works. It may be just one module
(most likely).

After OS Upgrade, Computer will No Longer Boot from Disc, Enter T-Disc Mode

I purchased the Leopard update about a week ago and proceeded to install it (upgrade option) on my MacBook Pro previously running Tiger. After this update, I no longer seem to be able to boot from a disc(c on startup), enter target disc mode(t on startup), enter single user mode(command s on startup), basically anything that requires hitting a key on boot. In short, the operating system seems to override any of those commands and just loads regardless of what I press.
How can I fix this?? I fear that if my mac suddenly dies, I won't be able to fix it with archive and install via the CD, since I can't boot from it. I also won't be able to recover my files with target disc mode or anything.
For more in-depth details:
-My hard drive does have an open firmware password- it was recommended as part of the undercover anti-theft program that I use. Although I can tell putting the password on was a mistake, since I've read that single user mode is no longer accessible with this password active. I don't think this is affecting my inability to boot from disc or target disc mode though, as I was always able to do this with Tiger, even with the firmware password active.
-I have tried booting from other discs, like my old tiger OS disc that came with the laptop- that fails too.
-My Leopard installation was not clean. Like many others, I used the upgrade option and it appeared to work ok- until restart, where I was faced with the blue screen. Since I was unable to boot to single user mode and try removing potential APE files, I let the computer sit for an hour on the blue screen until it finally loaded. Upon getting in, I found that I did not even have APE's installed. I proceeded to reinstall the operating system via an Archive & Install. Upon boot after this reinstall, I still received a blue screen that lasted a long time, and the OS loaded very slow. It did this for a few additional boots afterwards, and has appeared to smooth itself out now, a week later. The OS now loads fine and works alright (from what I can see), but I still can not boot from disc or anything else.
If anyone at all knows a solution for this, it would be much appreciated. I wanted to suspect something like the disc drive going bad, but being that things like the target-disc mode aren't working either- I'm hesitant to believe its just the disc drive. Being that it also happened just as I upgraded to Leopard and faced issues, I have more of a hunch that its something to do with Leopard.
I apologize if this has been answered before, but I've looked all over the site, google, everywhere I could think of and came up with no answer.
Thanks ~Brian

Hi, I have been having the exact same problem with a late 2011 MBP 15 inch. I replaced the hard drive with a samsung SSD 1.5 years ago, along with a samsung SSD in the optical drive. It worked great until the Yosemite upgrade. The MBP seemed to work reasonably well for a few days after the upgrade, but then it started stalling on various programs (spinning beach ball on Mail, Safari, etc). Start-ups were also longer and had a loading bar each time, which was new since the upgrade. I left the MBP to sleep last night and when opening it, it crashed and tried to restart. On restart it loads to the login screen, then after I enter the password it partially loads (based on the loading bar), then shuts off. I removed the SSD and plugged it in with a USG, but that didn't change anything. Here is a picture after using CMD-V before it shuts off.

Strange issue with RAM upgrade: It works but it doesn't! Please help.

Hello Everyone,
I have a very strange issue with my iMac since upgrading my RAM from 4 to 12 gig. When I first installed the new RAM it booted up and ran great. The next time I went to boot the iMac up it swtiched on but didn't get as far as the first white boot up screen. I tried turning it off and on a few times using the power on/off button but still no success. I decided to remove the RAM and reseat it. The computer then booted up again fine. Here's the problem though: when I went to switch my iMac on the next day it wouldn't boot up. Again, I took the RAM out and put it back in and the iMac booted up fine. I've checked the status of the RAM in the system profiler and it reports that everything is OK. So, I'm at a loss. Obviously, I don't want to go through this process every time I want to start up my Mac. Any ideas/solutions would be very gratefully received.
Many thanks in advance.

I completely agree with you. It will be one of the 3 issues you outline. The machine was bought brand new and has never given me a problem. It is just the introduction of the new RAM that has started a problem. However, I did just risk a restart and it booted up fine. I don't know if a restart is any different to shutting down and then pressing the on/off button to start the computer. Maybe my last reseating has done the trick or maybe my thinking is flawed because restarting involves a different process to booting up by pressing the on/off button. I don't know.
In the part of the world I'm sitting in it's night time now so I will leave the diagnostics running and check the results in the morning. I hope the issue is now resolved anyway. This sort of thing takes me back to my dark PC days although in this case I know it's probably not the Mac's fault.
Thanks again. Very much appreciated.
