BEEP!! BEEP!! FAAAAANNN....... After RAM install.

BEEP!! BEEP!! FAAAAANNN....... After RAM install.
I installed two 1GB RAM chips into a recently acquired 17" G5 imac (1.6GHZ).
When I turn it on. It goes BEEP! BEEP! WHIIRRRR! (the fan).
I uninstalled it and put in the old stuff and it worked fine. Is the RAM bad? Or is it operator error?
Regards,

Bad RAM. Hopefully you can return it and get new sticks.

Compaq Presario CQ57 - Will not boot after ram install

I was upgrading the ram on my father's old compaq, and was going along fine. I got the ram in, closed it all up, and went to boot it.
I was greeted with a black screen, a blinking caps lock light, a blinking power button light and the orange wifi light. I've made sure it has no static multiple times, and have tried slowly reintroducing power sources. I have cleaned the ram and the input, swapped out ram cards, everything anf nothing seems to work. When I turn it on I hear the CPU fan, and a single beep, then silence after a few more seconds.
Anyone wanna help me with this? I'm a mac lass now a days, so this is a bit out of my memory.

G5 won't start up after RAM installed

I added 2 512meg Kingston RAM to the computer on Thursday. No issues, worked fine on Friday, and this morning. (I will have turned the computer on and off several times over the three days).
Whilst running Nikon Coolsan V and cleaning up the finder, the computer froze. After a few minutes I did a restart by holding start button.
Computer will not restart. The computer will not start with the Tiger CD or in Target mode.
I reset SMU, no change.
I removed the new RAM, reset SMU again, computer still will not start up.
Attempted to reset PRAM, but nothing happened, and computer did not restart.
The computer powers up, makes start up noise, etc. as per normal for about 5 seconds, and then nothing happens.
I have also tried removing all the the RAM, and installing again in pairs. No change.
At this point the computer does not even spin up to the apple screen (which it did the first few times after the crash).
It has two internal hard drives, both of which should be bootable.
Any ideas or suggestions?
Thanks

You need Disk Warrior from Alsoft. Your directory is kaput.
Pull the data cable, pull the drive. A damaged directory can actually prevent booting from DVDs.
When a system freezes, don't just assume you can reboot and go back to work.

Problems after RAM install on 450mhz iMac DV+

I've been trying to upgrade my old iMac DV+ First, I installed Mac OS 10 on it and although it installed, after looking in the system profiler, I discovered my machine had only 64mb of ram and 10.0 really needs at least 128. It also still has OS 9.2. Needless to say, it was barely functioning. I purchased two 256 mb Kingston SDRAM, 168 pin PC 100/133 today and followed the install instructions on Apple Support. The machine booted up on the second install attempt (the first time, I hadn't pushed the RAM in quite far enoungh) and the desktop looked normal "About this Mac" showed the 512 mb- success- I thought. Then, I tried putting in a Tiger install disc that my school gave me because they had an extra license. Before trying to install Tiger, I decided to check how many gb I had on my hard drive, so tried to open system profiler to check the specs. My desktop displayed some very un-mac-like black block/white print error messages and the computer froze. The Tiger disc was still in the computer, so I restarted again with the mouse held down and the disc ejected. I got the flashing question mark folder for a few seconds, then a blank screen. I had to shut off power. I've tried re-installing the RAM, taking it out and putting the original 64 back, resetting PRAM, and now I just have a green light, no question mark, and a gray screen. Any suggestions? I don't have much on it that isn't on my other machines. Can I go for a clean reinstall? Is it the RAM or something else? I'd hate to lose this machine, as it still could be very useful in some ways.

First, you need to install a firmware update. This must be done when booted directly into OS 9.1 or higher, but not OS X.
You will need a minimum of 128 MBs of installed RAM for OS X and 256 MBs for Tiger (10.4.x.)
OS X will require at least 6 GBs of free space during installation and at least that much additional free space should be available on the hard drive. The hard drive must be formatted Mac OS Extended.
You certainly can do a clean install. In fact I would recommend that.
Given the age of that computer you may need to replace the internal PRAM backup battery if it's never been replaced. It's a 3.6 Volt, 1/2 AA size lithium cell available at Radio Shack, battery specialty stores, and some photo supply stores.
In the future you should post questions about iMacs in the iMac forum. This forum is for Intel Macs.

Core Duo random restarts after ram install

Hi,
I am aware of kernel panics caused by bad ram, but not random restarts. Well, here is the list of problems since installing 2GB ram:
1) 1 kernel panic about 10 minutes after installing said ram
2) 3 random restarts about 24hrs apart while working.
Is this indicative of bad ram, or do I have a different problem?
Other than that, I love this mini.
Thanks,
Berndt

Hi Berndt,
Just wondering if that Mushkin brand memory is still working fine in your Intel MacMini Duo. I've checked out Mushkin's website and they do not list the Intel Mini as a compatable machine but every other Intel Mac is listed. Maybe they just missed it, I don't know. That's why I'm curious as to whether you're having continued success or not.
Thx.

Airport doesn't work after RAM install

I upgraded RAM on my Mac Mini. Followed directions and all is good. Mini with new RAM is running great; however now, my Airport doesn't see my or any neighborhood networks. Prior to the install this was all working fine.
I can' figure out the problem. Any suggestions on what to do?

Excellent! That was it. Thank you.
And notes from a novice: For those looking to upgrade RAM in the Mac mini (Intel) there are 3 things to note when pulling out the internal frame: 1. The little black (thermostat fan) cable up front. You must unhook but if you forget to reconnect the fan runs all the time. Not good; 2. The gold (audio) band in the back. This too came off very easily. Very small (plastic) clamp that was tedioius to set back. Lift internal frame and turn like a book page; and 3. the airport cable. There are 2 small circular (beige color) ports. Use the MAIN (it's in tiny print) near the back.

System rebuild after RAM install

I tried to add another stick of 512mb Corsair XMS PC3200 400mhz and immediatley had to clear CMOS and reset BIOS after the system failed to reboot . Taking the stick out allowed me to boot properly and get the system back-up. I RMA'ed the stick got another of the same and now I had a lsass.exe error which forced my local computer shop to reinstall WinXP and start from scratch (reformat the drives). Has anyone had any luck running Corsair XMS across all three slots for a total of 1536mb? Memclock has been tried at 400mhz and 333mhz...I'm now running at 333mhz with only two sticks. I have sticks seated in slot 1 and 2

well, the response ure most likely to get is that your PSU is underpowered on the 12v line for such a hefty rig.
Things u can try tho, set the 2nd value in the ram timings up at least one. If you are using all three slots then max is 333mhz btw.
Update to latest bios, not sure if it has many ram issues fixed in it, but tis wortha try.
oh and read up threads about SATA and RAID on this site, although i havent found problems some people have with drives corrupting, maybe thats where your lsass.exe went...
i have corsair xms and has been stable a long time now.

Occasional restarts on mid 2012 macbook pro after ram install?

Hi,
Recently installed 2x4gb Corsair Vengeance DDR3 memory to my mid 2012 Macbook Pro 13" to upgrade the ram to 8GB.
Since then i have been having almost daily forced restarts, where it says it has to restart because of a problem, i believe it
is a kernel problem.
Also have been experiencing many repeated "Aw Snap" messages on Google Chrome although this could be unrelated.
The specifications for my mac are:
OSX Mavericks 10.9.2
Processor: 2.5 GHz Intel Core i5
Memory: 8 GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 1024 MB
Has anyone had any problem with this type of memory? I believed it would work when i bought it.
Original memory was 4GB that came installed in the Macbook Pro.
Other than occasional restarts, everything seems to work fine other than "aw snap" messages on latest version
of chrome (have tried disabling extensions, making a new user profile, reinstalling Chrome, none of which has worked).
Would appreciate any help, advise etc. Will be reinstalling original memory, see if the problem persist.
Cheers
Tom

The RAM must be stated by the manufacturer to be compatible with a mid-2012 MacBook Pro.
Just because it says:
1600 MHz PC3-12800 DDR3L SDRAM SO-DIMMs (204-pin)
Does not mean it is compatible. It must say mid-2012 MacBook Pro RAM.

Weak Airport Signal after RAM install...

I just installed a new RAM chip in my girlfriends G4 iBook and I am noticing a considerable loss is wireless signal from the airport card. The system profiler recognizes the card, and I have doubled checked to make sure I installed the card properly. Anyone have any ideas what might be wrong?

Probably the antenna wire is not properly installed into the card. Check the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card to verify proper installation.
Otherwise... the antenna wire is probably damaged.

IMac sometimes beeps endlessly after wakeup

I'm not very familiar with Mac computers, though I'm very experienced with Windows computers, so I might overlook or misunderstand things obvious to someone more familiar with Macs. I'm helping a less technically-oriented friend with her Mac. I'm not sure I have all the information that is needed, but let's try.
The computer is a fairly old one-piece iMac. The "About" choice under the Apple menu says it is an iMac 5,1 and SMC version (system) 1.8f2. The current OS is 10.6.8. I believe the original OS was one of the 10.4 versions. The computer originally used a wireless keyboard and wireless mouse, both from Apple. Sometime after the upgrade from 10.4.x to 10.6.8, the wireless keyboard and mouse were replaced by a wired keyboard and mouse. There is an HP inkjet printer connected to the computer. The owner of the computer is not certain of the timing, but believes the beeping that is the subject of this post started after the switch to the wired keyboard and mouse, but she admits that it might have started before the switch. She is confident that it started sometime after upgrading to OS 10.6.8. She was told by the staff at an Apple Store that she needed to upgrade to OS 10.6 in order to use Skype, or some new version of Skype (I am not sure about that reason).
The problem is that, at times, the computer will emit one beep or a series of beeps (the owner sometimes calls them clicks, but I have heard them and would use the word "beep"). The owner has reported only one situation in which a single beep occurs. Usually, it is a repeating series of beeps, each of the same duration (about half a second or maybe a little less, I'd say) and with a uniform interval between them, though I can't say whether the interval between the beeps is the same as the duration of each beep.
The beeping usually starts immediately after the computer wakes up from the sleep state (done by pressing a key on the keyboard). The owner usually puts the computer into the sleep state when she is done working for a while by selecting Sleep from the menu. I imagine it sometimes goes to sleep on its own due to exceeding the configured time of inactivity, but I have not asked her that. Sometimes the beeping does not start immediately after wakeup, but when a folder on the desktop is opened. When the computer is emitting a series of beeps, the beeps usually can be stopped by opening Safari and starting to type a URL. Typing the first letter of the URL stops the beeping. The owner is not sure whether starting any other program also can stop the beeping. If the beeping started when a folder was opened, usually closing the folder makes the beeping stop. The owner says that she thinks opening a folder containing Word files causes the beeping (though that does not trigger beeping all of the time), but most of her folders contain Word files, so I'm not sure it actually is necessary for there to be Word files in the folder to trigger the problem.
When the computer is emitting the series of beeps, the owner reports that the menus respond differently than normally. She says that, normally, when she clicks on a menu, it stays open while she makes her selection from it, but when the computer is beeping, she must hold the mouse button down while selecting her choice, else the menu will close.
The beeping does not start after every wakeup, but once it has started beeping after a wakeup, the beeping starts at all subsequent wakeups until the computer is shutdown. The owner does not know whether a restart rather than a shutdown also stops the beeping after wakeup. When beeping occurs after a wakeup and has been stopped by starting Safari, the owner believes that the computer does not resume beeping again until it has been put to sleep and is awakened again.
The owner has not had the computer start beeping right after being turned on, however, it sometimes does emit a single beep when the first letter of the user's password is entered into the logon dialog box. This single beep did not occur on a test of using the logon dialog after logging off without shutting down. (The owner does not usually log off, but I had her try it just as an experiment to see whether the single beep would occur when logging on in that situation.)
Possibly related is that there have been times when Word documents will not open. The owner mentioned that when this happens, if she hovers the pointer over the Word icon in the dock, she gets a choice to force quit. I believe she said that using the force quit restores normal operation of Word. There also has been at least one case in which Safari refused to close. I don't know how common this sort of stuck program is in a normally-operating Mac, and I don't know how often it occurs on this Mac.
When I was observing once, when I asked the owner to log off, the logon dialog box proceeded to shake rapidling left and right a small distance (perhaps a centimeter or so) while the computer emitted a series of beeps different from the other series of beeps I described. This series of beeps had two beeps in rapid succession, followed by a longer pause, two beeps in rapid succession, longer pause. This repeated until a key was pressed. The owner has seen that occur only that one time, but she does not normally logoff while leaving the computer running.
We have uninstalled and reinstalled Office (including all the updates to make it current). We have verified that Bluetooth is not enabled, that the old Bluetooth pairings have been deleted, and that the batteries have been removed from the wireless keyboard and mouse. We have reset the PRAM and the SMC. We have run the Apple Hardware Test and it found nothing to report. We have disconnected and reconnected all of the cables (keyboard, mouse, printer, ethernet). The problem of the endless beeping after wakeup sometimes still occurs.
I imagine the next logical thing to try is to reinstall Mac OS. The owner is a bit reluctant to try that. She does have copies of her personal files on CDs, but she is reluctant to undertake reinstalling the applications. Reinstalling the OS without erasing the hard disk probably would be less disruptive, but is there much chance that would eliminate the beeping? My guess is that something in the software somewhere has gotten messed up, and a completely clean installation would be the only way to guarantee to clear it up. Am I discounting the chances that just reinstalling the OS could fix it?
My feeling is that this is a software problem, not a flaky piece of hardware, but is that justified? If it might be a hardware problem, which part of the hardware might it be?
At one point, I had an idea that there is some software remnant of the wireless keyboard or mouse software still active that sometimes causes fake input that triggers the beeping. However, I don't know enough about the Mac to know whether that is a reasonably likely possibility, and, if it is, I don't know what to do about it.
All suggestions for clearing up this beeping problem will be accepted gratefully. Suggestions of other experiments to try also are welcome.
If we do decide to try a clean install of everything, should I first install the OS from the original discs that came with the computer, then upgrade using the OS 10.6 discs, or should I just start with the OS 10.6 discs?

Hello, excellent work so far!
It doesn't sound like this much, but including for pondering...
The following table lists the new tones and their meaning:
Tone(s)          Description
1 tone, a 5-second pause, repeat          No RAM installed
3 successive tones, a 5-second pause, 3 successive tones          RAM does not pass data integrity check
1 long tone when holding down the power button          Firmware upgrade in process. See About firmware updates for Intel-based Macs for more details.
3 long tones, 3 short tones, 3 long tones          Firmware restoration from CD in process. See About the Firmware Restoration CD (Intel-based Macs) for more details.
http://support.apple.com/kb/HT2538
Can you count the beeps or flashes?
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
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
It sounds more like some Hardware issue at the moment, but only by a slight margin.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Mac Pro not starting after new RAM install.

Hey everyone,
I have a Mac Pro Mid 2010 2x2.66 GHz 6-core (12core) Mac Pro with OSX 10.7.5. I currently have 6gb 1333 MHz DDR3 ECC ram installed.
I ordered 16gb (2x8gb sticks) of RAM from newegg, specifically, 2 sticks of this ram:
Kingston 8GB DDR3 1333 ECC Registered Memory for Apple
I popped it in yesterday and when I try to start up, the LED light just flashes and the screen acts as if nothing the computer hasn't been turned on. It does not beep or make any startup sounds either.
As far as I can tell this memory is in spec. It is "Registered", could this be a potential problem? I have tried various configurations of which slots to put the ram in. The only thing I haven't tried is putting the 2x8gb sticks in by themselves to see if it might be a capacity or mixing of ram issue.
Does anyone have experience with this or know where I might be going wrong?

What you have not done is actually... what I would have done first to start with!
To make sure it works and works alone.
Mixing is suppose to work now, better, but as OWC found earlier, mix and match requires DIMMs that will.
There is more in depth on MacRumors about ranking, Registered and much more about using 3rd party and what to look for and does or does not work. Which is nice, they try and tend to keep everything in one place, one thread, easy to find and read.
And Newegg price isn't really different than say buying from MacSales.

Kernel Panic only after I install 16GiB RAM but it passed memtest and AHT

Kernel Panics occur after I installed the 16GiB RAM(Corsair Vengeance Laptop Memory Kit 16 GB (2x8 GB) DDR3 1600MHz CL10 PC3 12800 (CMSX16GX3M2A1600C10) in my MacBook Pro 17" 2011 early. It might appear in login window, or after using Safari for 2 or 3 hours. If I did't use the MBP overnight and just let it run, there would be strong possibility that kernel panic didn't occur. But on the next day when I went up and start using the computer, the kernel panic occur in half an hour.
I run the memtest for 12+ hours and Apple Hardware Test for 19+ hours, but no error was found. I tried OS X Lion 10.7.4 and OS X Mountain Lion 10.8 GM, and even a clean install of 10.7.4, but it still occur.
However, when I install one of the 16GiB a.k.a 8GiB, kernel panic never occur. I even tried one 8GiB with another my old 4GiB ram, and kernel panic didn't occur either.
I've tried to fix the problems for 2 weeks, and I did everything I can. So, can anyone tell me which part might be bad, Mac or RAM? Should I goto Genius Bar or ask Corsair for RMA?
Here's my latest panic log:

Thank you for your reply.
My 8GiB RAM is also two 4GiB DDR3 1600MHz (SAMSUNG) and it was running very well.
I also checked the intel documents (http://ark.intel.com/products/50067/Intel-Core-i7-2720QM-Processor-(6M-Cache-up- to-3_30-GHz), and it says:
Memory Types
DDR3-1066/1333/1600
If you have read my original reply to you post, I did mention that someimes it will work and sometimes it won't. Your Samsung might be rated at 1600MHz but the CL could be higher than your Corsair which is why it worked.
The memory Type you read in the link you provided is motherboard/logicboard depended. Your Logic board is rated at 1333MHz. So going 1600MHz will not benefit you since you're locked at 1333MHz.
good luck

My 6-year-old iMac is painfully slow after I installed Mavericks, despite increasing ram to 4 GB. Any help out there?.

My 6 year old iMac is painfully slow after I installed Mavericks, despite upgrading to 4 GB of Ram. Everything stops and I see the spinning beachball way too frequently. Any suggestions or solutions?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.

Powermac G5 won't boot after new PSU replaced- says no ram installed!!!

I've recently inherited a friends old Powermac DP 2.0 G5 after it died a death. After some testing I diagnosed that that PSU had died in it- something that seems quite common.
Having found some detailed instructions online, I sourced a replacement PSU and set about replacing it. All went well with no major problems. I put everything back together and then powered the machine on. The fans whirled to life but there was no video out. I then noticed that the power light was flashing twice and then a break.
I checked on Apple's website and it was saying that 2 flashed is no ram installed. Yet there are 4 sticks installed - surely these all can't be dead? Has anyone got any words of advice? I'll be gutted if it's the logic board as the replacement PSU was really expensive....help!

Could be the RAM, sockets, Logic board, only way to tell is to swap them out.
Have you done a PRAM reset...

BEEP NOISE AFTER SENT MESSAGE

does anyone know how to turn it off?
the (du nun) annoying tone after you send each message?
thank you

Sorry if I forgot to mention this, but i mean startup as in after I can see my wallpaper and the windows start menu button etc, not on the TOSHIBA loading screen.
I also run my laptop straight off the charger (no battery is plugged in most of the time)
My laptop starts, and it works fine after the beeps (which go away after a while, however I fear that it is a sign of bad things to come in the future) - the beeps happen after windows has loaded but practically freezes my computer for the next 10-15 minutes.
The laptop is fine, except for the beeping and freezing. - I do not have that much experience with changing settings at boot up but I checked and I can get into those things without a problem.
Overheating has been a problem (in the past and in the present)
Thanks for your suggestions, my apologies for not including some of the information.

BEEP!! BEEP!! FAAAAANNN....... After RAM install.
