Memory upgrade freezes iBook G3

Hello,
I just recently upgraded to Tiger 10.4.6 on my G3/800 mhz and the system works fine with the standard 256 RAM (128/128). However, when I installed a 512 RAM, the system would randomly freeze or just not start up at all. When I replaced the 128 stick, everything is back to normal and runs fine.
The system recognizes the 512 stick which places my total RAM at 640 MB.
Can you please expalin why this occurring.
Thank you,
Bryan

Hi, Bryan. Welcome to Apple Discussions.
It sounds like you got a bad (or incompatible) RAM
module. Ask the vendor for a replacement.
Hi,
I purchaced the 512 MB stick from MacMall.com. It's a 512MB PC100 SODIMM.
It said it was compatible for iBook/Pwrbook G3.
Before I send it back, I just wanted to make sure it was the right one.
Thank you for the for the feedback.
Bryan

I upgraded my iBook G4 from 384MBytes to 640Mbytes and upgraded from Tiger to Leopard. After a few weeks the HDD failed. New Leopard install reports: "insufficient memory". I need Tiger install disks so I can install

I upgraded my iBook G4 from 384MBytes to 640Mbytes and upgraded from Tiger to Leopard.
After a few weeks the HDD failed. I bought a new disk, installed it and trued to install Leopard, but the install fails reporting "insufficient memory".
I assume the installation requires more memory than the OS actually needs to be able to run.
I need Tiger install CD/DVD so I can install Tiger first and then upgrade to Leopard.

Call Apple Customer Support 1-800-767-2775, provide the Serial Number and specifications of the Mac, and for a reasonable fee, they will supply a replacement set of system discs (if available).
The discs will be for the original version of the OS that was pre-installed when the Mac was manufactured.
You need much more RAM than that.

Dual 867 MDD won't sleep after memory upgrade

Since yesterday my PowerMac G4 Dual 867 MDD has become insomniac. What changed since yesterday is that I installed an additional 512MB of RAM. So far as memory is concerned, there's the factory-installed 512 Infineon module; a second 512MB Kingston module (installed about a couple of years ago, and has been working fine ever since); and a third 512MB Kingston module (the one I installed yesterday) for a total of 1.5GB.
I am aware that sleeping issues can arise for all sorts of reasons (inc. USB peripherals) but it is pretty obvious that in my case the problem is caused by the memory upgrade.
The symptoms: Once I click Sleep on the Apple menu, I can hear the sound of the hard disks spinning down, but the rest of the box remains fully powered. The screen freezes and the computer has to be manually switched off, as the mouse cursor disappears from the screen and the keyboard becomes completely unresponsive.
So far I have tried the following: I have reset the PRAM (no luck there), and have tried switching memory modules to different sockets (basically, the single remaining free slot). I apologise in advance if that second troubleshooting routine might portray me as an ignoramus; I have a good understanding of things but cannot claim to be an expert.
I am a extremely frequent user of the sleep mode, and this issue has taken away from me all the pleasure that comes with a coveted (and long overdue) memory upgrade. I would deeply appreciate any help in resolving this.
Many thanks

Dear Dave,
Many thanks for your prompt response. I ran Rember (Amount of memory to test: "All". All other boxes unchecked - I was running other apps at the time). I cannot understand the results from the log, but I didn't get any feedback at the end of the testing. I attach the contents of the log below:

Frequent kernel panic due to memory upgrade?

My 3.5 year-old MacBook Pro started to have increasingly frequent kernel panics a while ago, sometimes even several times per week. The Apple Store said it must be connected to the memory upgrade (from 2 to 4 GB). However, having the modules replaced with new Samsung ones provided little relief. Could both memory upgrades have compatibility issues or is something wrong with the mainboard? Right now, I am mostly running Win 7 in Bootcamp. The cursor will just freeze following an action such as trying to open a web site or formatting a row in Excel.
BTW, the most battery life the machine ever gave me was two and a half hours, regardless of whether I was running Snow Leopard (with Parallels) or Windows.
Thanks!
Kind regards,
Hans Christian, Oldenburg, Germany

well... the first time i got the kernel panic. it was text overlay on my screensaver that was running. The second time the computer just froze. I wonder though if the kernel panic would have eventually happened.
i keep noticing now that this iChat Agent slowly creeps up during the day to about 2GB Real Memory and 2.4 Virtual Memory. is this normal or causing the freeze??

MacBook memory upgrade

Hi there,
I would like to ask for your experience with memory upgrades for white plastic MacBooks. I have one MB062LL/A (2.16 GHz Intel Core 2 Duo, 1 GB RAM) and I just ordered another one MB402LL/B (2.1 GHz Intel Core 2 Duo, 1 GB RAM) to replace my wife's old iBook.
Would the memory upgrade be identical to both of them? I infer that would need to replace 2 identical memory chips in each computer, since they do not have empty expansion slot, so in fact now they do contain 2x512 MB, is that right?
Is there dramatic Leopard performance and responsivity difference if I bump it up to 2 GB? (2x1GB)? Is it worth of money spent? Real life experience anyone? Would it matter to go even higher to 2x2GB? Any measurable effect on it?
What should I look for at my upgrade chips? What qualities would be the figure of merit? I did found a site (http://eshop.macsales.com/shop/memory/MacBook/DDR2/) where they seem to offer exactly what I look for, but would it work? and more importantly, would it work reliably? What brand would you go for? I've read all kind of horror stories with incompatible Memory and problems caused by it, and I would not like to take much risk. Where would you shop for mac memory?

Hi,
According to Other World Computing, the memory is the same in both models. Right now, they contain 512MB in each slot.
You will notice a bit more speediness with more memory, but nothing blazingly fast. It's up to you to decide if the memory upgrade would be useful. If you use the computer for internet, eMail, MS Office, and other programs like that, you may not notice much of a difference and for now, you may want to stick with 1GB. But if you feel the MacBooks are a bit sluggish with 1GB, and you are using more RAM hungry applications like Photoshop, then upgrade to 2GB. I don't think that you would need to go the full way and put the maximum 4GB. As I said before, it will get a bit speedier, but nothing shocking.
Personally, I've been using Other World Computing (http://www.macsales.com/) for 5 years and I have never has any trouble with it. They are inexpensive, reliable, and they offer great performance. Their RAM has never given me any trouble. And if for some reason something goes wrong, all of their RAM has a lifetime warranty.
Best of luck, and please post back if you have any more questions.

Memory upgrade on iMac G3 700, help with system crashes

I tried to do a memory upgrade on my iMac, so I bought two kingston 256 MB PC133 modules, but none will work, the system starts, but hangs in about two minutes after loading the desktop. I went back to use the older memory module wich is an spectek, but I need the upgrade, any ideas?
Thanks!
FedericoMG.
Ps: Sorry about my english... I'm from Argentina... :-P

Hi Federicomg
The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
http://support.apple.com/specs/imac/iMacSummer2001.html
Apple profiler from my iMac this is the original supplied RAM from Apple:-
DIMM0/J13: Size: 256 MB
Type: SDRAM
Speed: PC133-333
1) I would re-instal the original ram and open system profiler to see what type the ram is.
2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

MS-6195 memory upgrade

Hi,
My system is based on Ms-6195 K7 pro and Athlon 700 mhz. 192 Mb Ram (128Mb module + 64Mb module)
Problem:
when I try to upgrade memory with a sdram 256Mb PC100 module, the memory test can't finish and my system don't boot.
Please can you tell me how configure coreectly the BIOS or tell how to do.

MS-6195 memory upgrade.
I have also tried using new PC100 256Mb memory and am getting nowhere.
The ones that I have bought are single sided, [8 chips on only one side]
and do not work with my motherboard, however, if I put them into another,
older PC, it shows up as 128Mb.
So I assume that the DIMM is working OK, and that the 'old' PC has a memory size limitation??
I have tried the same things as wbs and Grommit and got the same results.
So I assume that the answer is in getting older DIMMs, double sided with 8 chips on either side.
Does this seem to be about right???

Memory upgrade fail - Kernel panic after put old memories back

I People, this is my first post here and unfortunately is to report a problem, not to help friends.
I did an memory upgrade last weekend. After this, he will not boot normally, only in safe mode.
I discovered that they sent me 1333Mhz memories, and my mac (mid 2009) supports only 1066Mhz.
I put the old memories again, however I believe that the system did not recognize.
As you can see below, the system recognizes two modules:
Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353237334448302D4348392020
Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353637334648302D4346382020
It is not true, I' using now 2 x 2GB, DDR3, 1067 Mhz (stock)
I tried to reinstall the system, but when I try, I got crash again.
how can I solve this issue?

Hi BGreg,
I already reset the PRAM as you said.
I've cleaned the memory modules as indicated by Linc above.
Today I formatted my harddrive to try a clean install, but system crashs after 5%, 10%.
There is something making me worried:
In one of my tries, I opened the system view to check my actual hardware configuration, and to my surprise, the system shows me 8GB installed. Cannot be. I have 2 x 2GB.
Where my system stores this information? There is a way to reset it? I tried last hour install the snow leopard, that cames with my mac, by DVD, but does not worked too.
Thank you all so far.
Giuliano

Memory upgrade

Hi,
Can I install 2 x Crucial 4GB DDR3 - 1333 SODIMM 1.35V 204 PIN - CT51264BF1339J on a Macbook Pro 13 inch late 2011?
Currently, I have 4 GB (2 x 2 GB) and I want to upgrade to 8 GB. There is a controversial info regarding this particular memory module, some people say it is not compatible.
When I look to the specs I find:
204 PIN form factor = OK
1,35 V = OK
DDR3 = OK
1333 = OK
SODIMM = OK
Max 8GB = OK (2 x 4GB)
Latency= 9 cicles (same that stock modules supplied with the laptop) OK
The thing is Crucial, sell an identical specs module that costs quite more. They claim it to be compatible with Mac. The also sell this one I mentioned as being not compatible. The funny thing is that specs for both are identical. I only find a difference on the pricing. So I am really confused.
Do they one to sell me a more expensive one like being specific for Mac or there is a hiden specification that makes the two modules to differ from each other?
Can somebody confirm this info to me, please?
Many thanks in advance
Best Regards

News on this subject:
A Crucial support representative replied saying:
"Mac compatible memory is guaranteed to work in your specific system. There may be subtle differences in non specific memory that will cause it not to work for you such as chip solution and the configurations of chips..."
Well, I find it very ambiguous technically speaking. If they sell good quality memory as they claim, I do not see which subtle differences will affect the functionality. The chip configuration is standard and chip solution is about quality. So Crucial should be all right as everyone claims (even if manufactured in China)
So I went a head and both 2 x CT51264BF1339J for a very reasonable Belgian price and installed it into my system just two minutes ago. I am writing this using the mentioned system.
I was on Google after 30 seconds of taping the On button. Although it did not changed a lot as this startup timing is more related to the Hybrid 750GB HDD (SSD + Conventional Drive) I upgraded few months ago.
I upgraded the memory to run Virtual Box and Parallel desktop more easily though it worked quite good with 4GB. I did not upgraded to 16GB because it is not necessary on my usage. Only one virtual machine at once + E-mail + Browser + some PDF opened. Some technical stuff and nothing like Photoshop or similar. Thus the huge money difference would have gone for nothing if I buy the specific Mac modules of 8GB each as "Crucial Memory Upgrade Tool" subjected me.

Memory upgrade not working

I ordered 8GB memory for my imac mid-2011 model.
I then tried to install and all I'm getting is three beeps telling me there's something wrong with my memory.
I've tried all configurations but can't get the 2x4gb modules to work.
I've had to stay with only the original 2x2gb ones it came with.
Can anyone please help.
The only difference, besides the size, between the two modules is that on the 4gb ones is says PC3-10600S-9-10-F2 and the 2gb ones say all the same except instead of F2 at the end it's F1.
Cheers.

Which would seem to suggest that you may (unusually) have a doubtful memory module. Less unusually, you would have paid over the top for it.
Many people on these forums speak well of the following suppliers.
In North America contact OWC … Upgrade Apple iMac Memory
In Europe contact Crucial.com … RAM Memory Upgrade
Both companies have facilities to guide you and will recommend the correct memory package to meet whatever needs you describe to them.
There may be benefits buying from your own geographical location insofar as Shipping charges, Local sales taxes and Exchange rates. Check out the basic memory costs and do your sums next time you buy.

Memory upgrade on Satellite Pro L40-15d

Hi
I have Satellite Pro L40-15d with 512 memory (Samsung) but I wont upgrade to 1GB. I have Kingston ktt667d2/1g I have tray to put in to both slots but nothing work I cant switch on computer.
But when I change for old one laptop is ok. What can I do? Install special program or update BIOS or maybe the memory stick is broken.
Regards

Hi
The notebook doesnt boot after the memory upgrade due to these different issues;
- memory modules are not compatible together
- memory modules are not compatible with the notebook
- memory modules are faulty
- one of memory slots is faulty
In most case the memory module replacement helps.
One hint; did you try to switch the memory modules in the slots? Sometimes this helps.
Several weeks ago I have updated my memory and the notebook didnt boot.
I thought its a memory malfunction but after module switching the notebook booted correctly.
Good luck

Memory upgrade on Satellite A50-104

I NEED TO FIND A 512MB MEMORY UPGRADE FOR MY A50/104 ANYONE NO THE CORRECT ONE TO BUY, I WAS TOLD ON EBAY THAT 512 DDR SODIMM IS THIS RIGHT. ALSO HOW DO I CHECK ON MY LAPTOP FOR THESE DETAILS IF THERE ARE ANY AND ANY OTHER SPEC BATTERY ,HARDDRIVE ETC

Hi
You have several ways to find out what memory module is compatible and supported.
You can use a diagnostic too like Everest, you will check the user manual or the Toshiba website for details or you will contact the service in your country for supported modules.
I will try to answer the question: The Satellite A50 should support PC2700 DDR-RAM like these parts:
PC2700 256MB (PA3311U-1M25)
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G)
Now its your choice. You can also google for the offers
By the way: Visit the Toshiba Options & accessories site. There you will find compatible parts

Memory upgrade on Satellite Pro A40

Can anyone please advise where is the best place I can get a memory upgrade for my Satellite Pro A40 laptop.
I think my machine is a PC2700 DDR. I am looking for either 512mb or 1gb.
Thanks in advance.

Hi
On the Satellite Pro A40 you will find 2 memory slots and you can upgrade the memory to max 2GB (2x1024MB)
It should be possible to use these modules:
PC2100 512MB (PA3164U-1M51)
PC2100 1GB (PA3278U-1M1G)
And
PC2700 512MB (PA3312U-1M51)
PC2700 1024MB (PA3313U-1M1G
I purchase the compatible parts and devices always form the Toshiba service partner in my country because so I'm 100% sure that this parts are compatible.
So I would recommend you also to buy the modules form the ASP in your country.

Memory Upgrade on Satellite Pro A60

I have upgraded an A60 Pro with a 1GB memory up but the Control Panel /System/ General tab still shows it as having 192MB RAM. This limits me downloading some Security Software from BT Yahoo.
Can anyone advise on how I can make the machine recognise the new RAM or is the 192 MB RAM noted different memory from the new memory upgrade?

If you use non-compatible RAM module it is logic that system can not recognize it correctly. I do not know who is the manufacturer of this 1 GB RAM module but if you want to use compatible one pick up some info about PC2700 1024MB (PA3313U-1M1G) or check Kingston web page.

Looking to upgrade Ram memory to 2gb on my NB300-108
Have looked at Toshiba website and the cost but there appear to be a plethora of alternative websites with compatible memory upgrades when I put in the part number.
Would welcome any experiences of the forum regarding alternatives etc
Thank you

According notebook specification you can upgrade your NB to 2GB. I recommend you to use high quality module offered by Kingston. All info about it you can find here .
I have NB520 so I cannot tell you more about NB300.
