G4 mini: RAM 512 beeps 3 times, 1 GB beeps one time - No boot :(

OK, so my little G4 mini had 512 of RAM. I bought a 1GB DDR 333 PC 2700 2100 stick, which should be correct, right?
Well, upon installing, I get a single long beep and the front light flashes three times. I figure, badly seated RAM; try again. No solution there
Went back to the 512. Now it beeps three times and the light flashes four times! :((
OK, "maybe I destroyed something in the process?... Let's try going back to the 1GB" Same as the first time; one beep.
Go back to the 512; three beeps.
Anyone can help me figure this one out? If you need more details please just ask! Thank you in advance.

I read the Apple guides and it look like for after 1999 models:
1 beep = no RAM
3 beeps = RAM did not pass self test
Well, after many changes the 512 started working again, so I don't know what the problems is/was or how to solve it. I'll stay with 512 for now, I guess

RAM error beep when trying to boot install disc

I'm trying to re-install OSX in order to get a clean system and upgrade the OS. However, if I try to boot from the OSX Leopard install disc, I get the three RAM error beeps. I bought new compatible RAM (2x2GB SODIMM), tried with one of the old banks, then the other, in both available slots, then the new RAM - nothing helps: Booting the system with no install disc inserted works fine, having it inserted results in the beeps. It doesn't matter if I try straight boot, pressing C, using rEFIt or going for the device's own pre-boot OS selection menu, nothing helps.
I had the screen replaced on warranty a couple weeks ago, but I do not assume that poses a problem. Can anyone help?
Thanks!

Why do you have rEFIt installed?
To be able to multi-boot OSX, Win7, and Ubuntu.
What is your machine and what OS X does it have?
Early 2011 MacBook Pro 15" non-glare screen. 4GB stock RAM.
What's on the disk 10.5 or 10.6?
The disk is Leopard, as far as I can remember. I believe I got Snow Leopard over the App store.
Have you cleaned the disk, use another?
I don't exactly have another disc ... but I tried to image them to a SD card and that gave the same results.
What are you trying to do exactly?
Completely wipe the drive (low-level) to be able to sell the device.

Upgrading Mac Mini Ram

i have a 1.66 ghz core due mac mini with 512 mb of ram. i want to upgrade to 2gb.
does the mac mini have 2 slots for ram and if so, what kind does it take?
is it still hard to open, do you still have to do it with a sharpened putty knife or have they changed that with the core duo's

Hello,
****, im no pro and i dont want to mess anything up
trying this. i also dont wanna pay through the roof
for mac ram
I can appreciate that.
any suggestions?
I would first find out if you have any Apple Authorized Service Providers in your area that are not actually owned by Apple.
Then, ask them if they will install memory modules that you supply. If so, then see what they would charge for the service.
If they say no, ask them how much they charge for their memory.
A lot of Mac Mini CoreSolo and Duo owners have complained of problems resulting from servicing the machines themselves. There are so many parts that you have to move and remove, that you need to be exactly sure of what you are doing when you put it back together.
So, if you are not comfortable doing it yourself, see if you can buy cheaper memory elsewhere and pay an Authorized Service Provider to install it. Many of them will do it if you pay for their time.
As for buying 3rd-party memory, I buy mine here:

I hope this helps.

MacBook Pro will sometimes beep 3 times on boot

Shallah
Feb 9, 2014 3:09 PM
This problem started in late January and continues till now. The first time I took it to the Genius Bar the employee opened the back and repositioned the RAM. ( the laptop would sometimes beep 3 times on boot so he thought it was a ram problem). This made it work for about a day then it started crashing again. The second time I went to the Genius Bar the employee erased all my data, with my consent, and restored the makbook to factory settings. This did not help either as the laptop won't even let me use photo booth without crashing. I used to not power off my laptop and let it run in sleep mode for long periods of time. Also I move around with it a lot. What could be causing this issue and how much do you think I will have to pay to get my MacBook Pro fixed. It's a late 2011 model running mavericks and the latest updates. I do not have apple care and the laptop is out of warranty.
I am running osx mavericks. Never spilled anything on it. Have 4 gigs of ram.
MacBook Pro, OS X Mountain Lion (10.8.5)

In addition to BobRZ's advice, try each module in each bay. In rare occasions that is the problem, not the RAM.
Also download from Kelly Computing, Rember and run it overnight or longer. It is a good test to determine if you have faulty RAM or not.

Mac Mini Mid-2010 Beeping every five seconds - HD Upgrade

I upgraded my Mac Mini Server (Mid-2010) with two 480 GB SSD drives tonight. The drives are Intel (ssdsc2bb480g401) drives. I know the mid-2010 mini runs at 3 GB/s and the drives I put in are 6 GB/s.
I thought the drives would work and just run at 3 GB/s. I'm getting a constant beep and LED flash every 5 seconds. I'm thinking the drives are not compatible.
Anyone else run into this problem?
I see a bunch online about memory upgrades related to beep sequences, but the memory is the original 4GB. No change there.
Thanks!

den.thed,
Thanks. I have done that a few times already with no luck. I just pulled the top module out and the computer booted. I pull the bottom module out and replaced it with the top one and it booted.
That tells me both modules are working.
I think put the extra back in the top slot and the beeping comes back. I have reseated a few times and still get the beep. Maybe a bad slot? Dammm static electricity is the only thing I can think of.

Three 3 Beeps after long resume, boots into OSX just fine. RAM Issue?

Hi everyone,
After about a year or so of experimenting with Hackintoshs with the OSX86 community (MSi Wind and Dell E1405) and an enjoyable experience with my iPhone, I've decided to pick up my first Mac. I ended up with the newer Macbook 2.4ghz. As a veterened PC user who had no problems with Windows, I find OSX to be very user friendly, so this computer has been very enjoyable indeed.
I went ahead and upgraded it to a 500GB HDD and 4GB of DDR3 RAM as soon as I got it, and by this, I mean, I booted it up to ensure it worked, then shut it down, and added the new parts.
I don't remember if this happened on the first bootup when OEM spec, but now, whenever the computer has been asleep for a long time (after I get up in the morning, or when I get back from work), I hear three or so short beeps right before the DVD scanning for a disc. I believe this also happens if the computer has been turned off a while. If I restart or shutdown for a "short period" it does not happen.
I did some research online, and most people say the RAM has a problem, but they all never boot or have major issues.
My MacBook boots, detects the proper amount of System Memory in "About this Mac", and looks to be just fine in System Profiler. I also ran the Apple Hardware Test, and it passed without issue. The MacBook has no functionality issues that most people contribute to bad memory (reboots, funny screens). Basically, if it didn't beep 3 times, I wouldn't have thought anything could be wrong. The only other issue I have is that it doesn't turn on the laptop's display when resuming from sleep (which is very annoying), something others are reporting as well.
The DDR3 I got is OCZ Brand. A silly name, but reputable brand. It looks to use the same brand Micron chips as the OEM Apple. A link to the Memory I purchased is here - http://www.amazon.com/gp/product/B001CNR39U
Does anyone have any insight into what could be causing the MacBook to beep 3 times whenever I boot up after a long time of sleep/off?
Thanks,
Jonathan

Sounds like faulty RAM. Get 'em replaced. I tend to trust Kingston and/or Patriot for my memory needs.
If that doesn't work, then try popping in the stock RAM. If those work, then we know the RAM you replaced is still faulty. Keep retrying. If the stock RAM still beeps, send the machine in for repairs.
Btw, a running joke between my friends, we call OCZ ... OverClockZors =P.

Mac Mini RAM upgrade: failure after one week

my system:
Model Name:          Mac mini
Model Identifier:          Macmini5,2
Processor Name:          Intel Core i5
Processor Speed:          2.5 GHz
Number of Processors:          1
Total Number of Cores:          2
L2 Cache (per Core):          256 KB
L3 Cache:          3 MB
Memory:          4 GB
After severe performance problems with Aperture, I decided to go for an RAM upgrade to 2x4GB. Went to my (non-Apple) dealer, got me two DDR3 1333Mhz Samsung bricks and put them in. Worked like a chime. Startup went fine, RAM types shown in the Activity Monitor with plenty of free RAM and great performance... for a change.
After a week however my Mac froze. A restart gave me two beeps and a flashing light in front. Manual tells me 'wrong RAM type'. Same situation after replacing only one of the bricks.
A bit weird after a week of juicy operation?
Getting back the old RAM installed resulted in a working Mac - but with the limited memory obviously.
Will go back to the dealer and have the RAM replaced next week.
Ever heard about RAM failing after a well?
/thanks!

UPDATE:
right, I went back to my dealer and got the RAM sticks replaced. the miniMac booted up at the store and is now working fine again. Let's see for how long.
Size:          4 GB
Type:          DDR3
Speed:          1333 MHz
Status:          OK
Manufacturer:          0x80CE
Part Number:          0x4D34373142353237334348302D4348392020
Serial Number:          0x005001B9
I had checked the serial number and RAM chip IDs with the Samsung tool from their homepage. Looked just fine.
To my limited knowledge about Silicon production it would not be too easy to produce fake RAM sticks that
- are accepted by the HW check
- show the capacity as specified
- .. but fail after few days (haha!)
I will update you about the latest with this story.

When I turn off my mini, and at other random times, i get a message saying I need to restart my computer

When I turn off my mini, and at other random times, i get a simple message that says I need to restart my computer. any suggestions?

The message to restart your computer, in multiple languages, is a kernel panic. This is usually, but not always, caused by hardware, with memory being the leading cause.
You might want to run the Apple hardware test, which is on the original gray-faced OS X disks that came with the mini. FInd the one that says 'AHT Version x.x' in small print on the label, insert and reboot holding the alt/option key down. Choose the Apple hardware test, and when prompted, choose the extended test. You can also download Rember from http://kelleycomputing.net/rember/ if you want to really test the memory. Set it up and let it run over night.
See this kernel panic FAQs for other ideas: http://www.thexlab.com/faqs/kernelpanics.html

New ipad mini retina: Safari crashes every time I hit the plus icon to open a second page

Brand new iPad mini retina, safari crashes every time it try to open a second window

Cleared and cleared then rebooted. Worked like a charm. Multiple windows open fine now, hardest part was navigating my way back here. Thanks dido ones... Bah auto correct diavonex.... Anyway, much appreciated. Just surprised it didn't work right straight out of the box, but possibly a hiccup from starting this device from a backup of my iPhone.

My ipad mini loses Internet connection every time it automatically locks.

My ipad mini loses Internet connection every time it automatically locks. I have to re-establish the connection but sometimes it would take too long for the Internet to be connected. I'm using a wireless connection

just browsing around I found this question. Also on my mini retina I fight with this problem. After a lot of searching I found that the only solution is to switch to
Airplane Mode, wait few seconds and switch again.
Or, if you are lucky, to find a Genius who replaces your unit. Cheers

Mac Mini + MacBook + wireless internet/router: Time Machine on external HD?

Hi all,
In theory, this is possible (I think) but I wanted to see if anyone had tried it because the guys in the Apple shop gave me crazy eyes when I suggested it.
I have a Mini that's being used as my multimedia hub. I also have a MacBook that talks quite nicely to my Mini over my wireless internet gateway (modem+router in one). I was going to buy a Time Capsule as I recently suffered some serious data loss after my Macbook power supply caught on fire (yes, you did read that correctly) and damaged my HD.
My question is, rather than buy a Time Capsule and suffer all the NAT/networking/bridge issues that other people are struggling with - can I just connect a 2TB external Firewire HD to my Mini and use Time Machine to back up from my MacBook and my Mini to the external HD?
If you can explain why this is a good/bad idea, I'll be really grateful!

Personally, I wouldn't attempt doing all that over a wireless network. You'll be pushing the bandwidth limits of wireless. Not to mention it's not the most reliable of network methods, so entrusting it to backups is also something I wouldn't recommend if possible.
I'd just get an external drive (FireWire preferably) and connect it to the Mini. If possible, bold the drive down to some permanent fixture in your place. External drives have a nasty habit of dying after about a year, because they usually take a lot of abuse in the form of little bumps and jolts. You bolt it down, so that it has to move in relation to some permanent fixture with considerably more mass, and it won't be AS likely to die early on you.

May be you can do something like this!
data: l_time like sy-uzeit.
data: l_time1 like sy-uzeit value '06'. "6 hrs to be deducted from system time
move sy-uzeit to l_time. "this is system time
"write l_time.
"write:/ l_time1.
SUBTRACT l_time1 from l_time.
write:/ l_time. "This is 6 hrs behind system time
