Memory Upgrade failure

I tried to install an additional 512 MB memory module on my iMac DV,
but I've continously crashes and computer freeze after a while.
I tried with 2 modules Kingston KVR133X64C3/512
What's wrong ?
Should I change something in the configuration too ?
Thanks
Franco

Ciao e benvenuto alle discussioni di Apple.
Kingston themselves don't support the use of their low grade KVR (Kingston Value RAM) in any Mac as I found out I my cost when I installed KVR in my iMac G4 and also suffered Kernel Panic type crashes.
For RAM in Europe I'd advise trying Crucial.

Memory Test Failure:

I was digging in my computer drawers for a plastic thing to hold one of my SD cards, and then I found a RAM chip that is 512MB. I need lots of these for the imacs, but I tried to install it, and it didn't work......
It is a Dell Memory. Make your next upgrade Dell Certified Memory. and there is also the sticker with the M with the circle around it and the small OS9-style font and a bar code.
It came with one of my imacs!!!!! It was inside it already. I don't remember if I took it out before or after one of the imacs stopped functioning. (also...could that be the cause of the damage of my first 500mhz imac??????)
I put it in a dark blue 400mhz imac and it has 10.3.9 and 9.2.2 but I have it set to boot into 9.2.2 and it said "Memory Test Failure" or something like that. Everything booted successfully. And then I went to System Profiler. And it did not say 512MB.
My very first mac was a power mac g3 and it had issues. I thought it would be any number of things. I dismantled it. While I did not have any 512 modules (I want and need lots of them) I decided, reluctlantly, to put in some of the 256mb modules in the imac. And...
One of the modules caused the imac to never boot. I took that one out. I put another one of them in and instead of the chime, it there was a sound that was similar length, but it sounded like a common stand-alone analog television not recieving any signals. That static noise with the white "snow"?? It sounded like that. "BZZZZ"!! I took that one out. There are two 256mbs, but I want 2 512mbs,
and...
THAT is what was wrong with the power mac G3?!?!?!?!?!?! I already took it apart, thinking there wasn't anything easily fixable on it!!!! }=S I guess I will put it together again... But that won't happen until I have some more RAM chips... I do not like 64 mb and 128 mb chips. }=S
All 4 of the 256mbs were functioning. I bought them as used, and it said that it will fit in g3s. Why are 2 of the 256mbs not functioning any more???? I once had Tiger on Power Mac g3. It is a blue and white g3. Could Tiger's Dashboard have zapped the ram chips??!!!!!!!
Anyways, for every imac, I would like 2 512 modules. Which ones will work??? Ones that are certified Dell are obviously not. XD
and will dashboard zap the memory?????? I do not have Tiger installed, but if I install it, will it damage the memory????? =S

Which iMac do you have? All iMac G3 models only have two memory slots.
What iMac do you have?
Query by serial number
"A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

You could buy an external DVD drive. It needs to be firewire and bootable by Mac OS. If you have another PPC with firewire, you could try target Disk mode and installed tiger that way.
You need to figure out the level of your firmware before installing 10.2 or greater. ( The PC name for firmware is BIOS. ) Installing 10.2 with a down level firmware will most likely make your iMac unusable and difficult to fix.
Open Firmware, boot into Open Firmware.

What firmware do you need?
http://docs.info.apple.com/article.html?artnum=86117
For a slot loading iMac, this article indicates that you need to be running 9.1 or later version of Mac OS Classic.

"The iMac Firmware Update 4.1.9 will only run on iMac computers with lot-loading CD or DVD drives running Mac OS 9.1 or later from a local drive. If you are using Mac OS X you must boot from a local Mac OS 9.1 or later writeable partition (not a CD, or network disk) prior to following the update instructions."
You can download the Mac OS 9 updates from the Apple site.

For tiger, you need 256meg of memory.

HP Probook 4520s Memory upgrade to 8GB (2x4GB) Corsair Unsuccessful and Failed

Ok, here is the story
My notebook is HP Probook 4520s
with Windows Windows 8.1 (6.3) 64-bit (Build 9600)
Please refer to the end of this post for CPU-Z report of specs.
Currently I have 3GB of memory installed -had to install them back after upgrade failure-.
Please refer again to the CPU-Z report for the memory module specifications.
I bought the following Corsair 2x4GB memory pack

When I installed the memory module onto the notebook, I basically couldn't go beyond the POST stage. That is the HP logo appears on the screen, and that's it.. that's it.. nothing beyond that stage.
When I went to the BIOS settings, the memory successfully read 81xxMB, this is basically 8GB of RAM.
I tried to reset BIOS settings, failed again.
I removed the 2x4GB modules, put back both original 1GB and 2GB modules -the ones that came with the notebook-, everything worked again.
What went wrong here..?
P.S. please do not reply with lame replies like "that's weird" "that's strange", I know it's weird and strange. I want specific and clear suggestions.

Specific and clear. Your laptop uses 1.35 volt memory and you installed 1.5 volt.

Report on memory upgrade

A couple of months back, I posted several questions regarding memory upgrade for my Mini 1.5 Core solo. I thought I would take a couple of minutes and report on the results.
With memory prices dropping like they have, I decided to take the plunge and upgrade to 2G. Wow! This is now the computer I thought I bought. I run Mail, Firefox, Excel [PPC], Word [PPC] and Quicken [PPC] - plus Norton AV [PPC] - regularly, and Google Earth, iTunes, iPhoto occasionally. Plus an HP printer [PPC driver]. My Page Outs were running 30-40% of Page Ins for my typical use. I waited for program swapping as well as function swapping within a program.
I now wait for virtually nothing! Page Outs are barely above 0%. Programs load faster, though actual processing appears just about the same [as expected].
I purchased Micron memory from Crucial, as I knew it would be "right". It is now selling for $132/2x1G, free shipping, plus tax in many states. In order to insure no problems with validity of my AppleCare Warr, I had it installed by my local [non-Apple] Authorized Service Center for $45. I justified 2G versus 1G by looking at 2x512M costing me about $113 [installed] to double the memory versus 2G costing me about $177 to quadruple the memory.
As I watch Activity Monitor, it is likely that 1G would have accomplished most of the improvement that I see, but I am NOT sorry I went to 2G now when memory is cheap.
Thanks to all who gave me their advice when I first posted.
MacMini 1.5 Intel Core Solo Mac OS X (10.4.8)

I just got the 2 GB Upgrade Kit from Crucial for $120 /w free shipping. Came to about $130 after tax.
I purchased a 1.83 Mac Mini with 512 MB of ram and an 80 GB hard drive 3 months ago. I decided it was the best solution for a recent computer failure. Although quite fast especially for CPU intensive tasks the system would hang on particular tasks.
1) Parallels was virtually unusable (even more so if I had anything else running)
2) iTunes had problems displaying all of my album covers in the jukebox mode
3) Protoshop / Painter slow to load
4) Widgets were slow to load
Having the correct tools for the job, installation of the 2 GB kit was rather simple. I didn’t seat the top SO DIMM correctly the first time around but I was smart to test the system before closing the case.
Improvement was noticed almost immediately.
1) Boot times increased
2) The infrequent Beach Balls disappeared
3) Parallels is not only usable it’s like having a 2nd computer
4) iTunes has no hang ups
5) Photoshop and painter can handle large images with many layers without slowing down. (Large brushes in painter kill the system, but that’s CPU related)
6) Widgets launch faster but not as quick as I would have expected
Over all the upgrade was completely worth it. It is like a whole new computer. Bottom line 512 MB is the bare minimum for OS X 10.4 assuming you do nothing more then Brows the internet, Chat on line or use it as a media device.
I have a hard time justifying the upgrade through Apple’s site. It’s not worth the $120 premium when instillation should be simple for even an above average computer user. Either way I couldn’t recommend any one use a mini with 10.4 with anything less then 1 GB

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.
Christine

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.

Memory upgrade on NB300-108

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.

Memory Upgrade on DV7T-3000 (NQ339AV)

Hello,
I have a Pavilion DV7T-3000 with i7-820QM Processor. I am planning on a memory upgrade. Has any one tried upgrading it to 16GB RAM ? (2 x 8GB). As per specs it can only go up to 2x4 GB.
Thank you for for any feed back.

I believe you should try to PM a level 8 or higher expert here and see if they will access someone from HP.
