PowerBook G4 RAM Upgrade, suggestions

Hello there Apple Masters
My PowerBook G4 is relativly slow since the insertion of a new hardrive. The last one, died sundely on me, and needed to be replaced. After that, for some reason, the computer is very slow. I am running Leopard and while running any kind of application, is soooo slow. I also notice a funky sound while the disk is spinning...
Anyways, so I was suggested to upgrade my RAM which is onnly 512MB. Before, I didn't need more, the machine runned really nicely/___sbsstatic___/migration-images/migration-img-not-avail.png But now it seems otherwise. I was suggested to upgrade to 2GB, but I have only found 1GB of RAM on the online shop where I would like to order this product.
My questions would be, could you take a look at this model and tell me if this is the RAM that is compatible with my PowerBook G4, 17", 1GHz: RAM 1024MB Kingston Qualitätsspeicher, 333 MHz, PC2700 SODIMM Memory Module für Apple iBook G4, Powerbook G4.
If not, which one should I look for.
Here also a link to where you can see the picture (althoug I am not sure it actually looks like that):

Sorry if the website is in German, but I am currently working in Germany and need to buy the stuff here
I also would like to know if I can install this type of RAM my self, or if I have to have someone do it for me. Where can I see a manual on how to do this?
Thank you for your ideas

Apple specs and Do it yourself guides got pulled probably...
Probably not a good idea to restore files, they could have trouble. May have been backed up while there was a problem and data corruption.
As for Disk Warrior, it is commercial product by Alsoft. Another choice is your AppleCare TechTool Deluxe or Micromat's commercial version TechTool Pro, but you do need 3rd party utility to take it from where Apple Disk Utility leaves off.
A lot of tips on memory upgrades to do yourself from a number of sites.

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.

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.

Memory modules can we use for RAM upgrade of HP Pavilion dv5-1198de??

What memory modules can we use for RAM upgrade of HP Pavilion dv5-1198de??
Max RAM? Vista? Windows 7?

I can't find a dv5-1198de but I did find a dv5-1198er which should be similiar. It states up to 8 gb of ram. HERE
I would try www.Crucial.com for suggested memory ,you can use their Scanner Tool to let it detect what you have and what you can upgrade/replace with.

First go to the RIM web site and look to see if they have an uninstaller for the device you had. Some times a reinstall of the application and then running the uninstaller is required for complete removal.
If no uninstaller is available, then you will have to use Spotlight to find all items with 'Blackberry' and 'Rim' in the titles. I would also download EasyFind and use that to locate such files. Often it will locate items that Spotlight misses.

This is the regular status of the memory of my macbook pro. Do you think I need a RAM upgrade?

Hi there,
I'm hoping to seek the expert views of the community here.
I have a MacBook Pro, Late 2011, 17 inch. Running latest version of Mavericks. Speed seems to have slowed somewhat, perhaps since I upgraded to Mavericks, but not certain about that. Based on my research of the Apple communities, I suspect that I may benefit from a RAM upgrade.
Attached are a few screen shots to assist:
Based on what I have researched in the community, the fact that I have used 3.99GB of 4.00GB, and have used 5.63GB of Virtual memory, seems to suggest to me that I have well and truly maxed out my RAM. Also there is a high number of read ins/outs (but it had been a wheile since I last did a restart on the MBP (if that has any effect on these numbers here).
I have also read that my model of MacBook Pro is upgradeable to 16GB of RAM (2 x 8GB).
Thoughts and views from the community would be greatly appreciated. Will additional RAM help the speed and performance of my MacBook Pro?
Many thanks.

More RAM is always a Prudent move...

It will certainly help with Performance.
Macs can be very Fussy about RAM...
You can use these Links to check which RAM is suitable for your Mac...

It is Important to get the Correct and Matching RAM
Those sites also have videos on how to Install RAM should you need it....

My Pro has had RAM upgrade. Will not login.

My Pro has had RAM upgrade. Brand new compatible module. Boots fine but will not login.
The password is typed in correctly (per account).
A light grey screen & mouse cursor appears then we are cycled back to the login page. If we deliberately try an incorrect password we get the 'shimmy & shake' of an incorrect password.
The H/W test passed.
What do you suggest?
Many thanks!
Andy.

I don't own a MBP but that sounds bizarre. Did it shut down as soon as she plugged it in?

Battery drains while sleeping after RAM upgrade

Installed 16 GB of RAM and a Hybrid/SSD 1 TB internal HD on MacBook Pro 15" mid 2012 and now the battery drains while the computer is in sleep mode, about 1-3 % per hour. Before the RAM upgrade (stock 4 GB of RAM) there was no noticeable battery drain, so I assume it has to do with the upgrade. I read that it takes more power to maintain 16 GB of RAM during sleep, so my questions are as follows:
Is 1-3% per hour normal?
Will resetting the SMC help the issue?
Does the Hybrid HD have anything to do with this?
I am not too happy about the battery drain as it happens that I don't use my laptop for some time and prior to the upgrade the loss of battery charge was not an issue at all. Is this the price I have to pay for maxing out my RAM or is there a way (resets, settings, etc) to reduce the amount of battery loss
Thanks for your input.

Hi everybody. I have the same question. I have a macbook unibody late 2008. I have recently upgraded the OS to Yosemite. In order to have a smoother functioning of the system I have immediately replaced my original 2Gb (1+1) RAM with 8 Gb (4+4). Since then, I have noticed a dramatic reduction of my battery charge during sleep mode. Now after 8 hours of sleep it goes from 100% to around 65% (before it was 95%). Is it a natural consequence of having installed a larger RAM or there could be anything wrong with my settings?
I have read a couple of articles about standby mode and standbydelay setting but this does not apply to my model of macbook.
Here is my pmset -g result:
Active Profiles:
Battery Power        -1*

Issues with sleep/wake feature after 16GB RAM upgrade in my MacBook Pro. Any thoughts?

Just installed a 16GB RAM upgrade in my MacBook Pro and now it doesn't wake up on it's own when I open the lid. I have to press the power button. It works fine with a smaller RAM upgrade.
I've tried putting in just one of the 8GB modules and the sleep/wake feature works as normal so there isn't a problem with the RAM modules that I've bought (Crucial.com). I've also put in a combination of Apple's original RAM and the new ones to make 10GB (8GB + 2GB), and the sleep/wake feature works on that too. Put both 8GB modules back in and the MacBook doesn't wake up when I open the lid, I have to press the power button to wake it up. The MacBook itself works fine, super fast and the memory is recognised on 'About This Mac', the sleep/wake issue is the only problem I'm having with the 16GB RAM.
Any thoughts on this? Has anybody else had this sleep/wake issue like this when upgrading RAM?

I upgraded my early 2011 MBP to 16 gigs with Crucial. My machine would not sleep properly, because when I tried to wake it, it would wake from its hibernate image file. This is the issue I've seen here in this list.
I tried all the suggestions I saw on these groups. Nothing helped. I contacted Crucial, who suggested that if their RAM was defective, they'd replace it per their warranty process. I needed some proof it was their RAM causing the problem.
I put the original 8 gigs RAM back in the machine (2 4 gig sticks), and it behaved normally. I then put one stick of Crucial RAM in, all by itself. The machine behaved normally. I put the other stick of Crucial RAM back in, and took the first one out. The machine would not properly sleep and wake from sleep. This proved that one stick was causing the problem, and the other was not.
Defective RAM!
I then requested and received an RMA from Crucial to send the defective RAM back. They paid shipping. I got new sticks of RAM about a week later. These new sticks of RAM work properly. No sleep issues.
I'm surprised and disappointed to say that this is not the first time I've received defective RAM from Crucial. I've purchased from them for years, and had GREAT service and received high quality products. The past couple years my experience has been different.
I'm still pretty steamed about this, as I spent a great deal of time trying to diagnose the problem and fix it. I don't really have that kind of time to waste. My expectation was that their RAM was high quality, and unlikely to be at fault.
Perhaps this is just a bad batch of RAM. I get that. I can forgive them once. But this has happened twice in the past three years. I'll look elsewhere for my next memory purchase.
Keep in mind that their customer ratings are generally very high. My experience is probably isolated.

Lenovo G40 ~ 70 ram upgrade problem

I bought a lenovo G40 ~ 70 laptop and I wanted to upgrade my ram.It contains 4gb ram and I wanted to upgrade it to 8gb .What type of ram card should I buy and after the upgrade will my computer have problems? thank you.

Hi Ayato,
Welcome to the Forums
As per the query we understood that you are looking for RAM upgrade for your Lenovo G40-70 laptop.
As per the specification of this model , the maximum memory supported by this model is upto 16GB DDR3L 1600Mhz.Hence I would suggest you to look into DDR3L RAM as the RAM slots in the laptop will only support the same. And "L" in DDR3L refers to low voltage.
Click here for the model specification.
Hope this helps. Do post back if the issue persists.
Best regards,
Ashwin. S

Problems with RAM upgrade iMac G5 1.8GHz

Stuck - Need Help!
I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
Followed instructions to T, but with the two new chips in, the machine won't load.
Interestingly, it boots up with the following RAM combinations
old 500MB + new 1GB (in any combination) - recognised as 1.5GB
one new 1GB RAM (again either one) - recognised as 1GB
I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
Anyone overcome a similar problem in the past?
Thanks

I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
Anyway, here goes:
Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
Upgraded A: Added 1GB stick = 2GB total
Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
Any thoughts are appreciated.

What is the maximum ram upgrade possible on a Mid 2011 iMac 21.5-inch

I have an iMac 21.5-inch, Mid 2011 running OS X 10.9.5 which currently has 4 GB 1333 MHz DDR3 Ram. The Hard Drive has 149.87 GB free out of 499.25 GB. It has been running slow for a while now. I would like to know what is the "TRUE" maximum Ram Upgrade possible. The reason I say "TRUE" is because the specs say one things when I find others saying another. I would like to install the maximum Ram that will increase the speed to its optimum. I have read some information that this particular computer will not take advantage of anything past a certain amount of ram.
So with all that said, I am asking for specific numbers, types of ram, suggestions etc etc...
Thanks

Here's what you can do and need:
Maximum Memory
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Sources for memory I recommend are:

Ram upgrade to 2GB - fan running faster

I have just upgraded my intel mac mini from 512 MB to 2 GB using a kingston upgrade kit (KTA-MB667K2/2G).
The system is performing a lot better but there is an annoying "trouble": when 2 GB are installed the fan is running more fast and more often then with 512MB.
During my tests, I have see that while using OS X the system is able to regulate the speed, it goes from very slow to very fast but it moves to fast more often then before and the system is definetly making more noise.
The bigger problem happens when booting using windows XP: when 2 GB of RAM are installed the fan is always running at top speed or near to top speed.
That is not happening while using the original 512 MB.
I have tried to reset the SMC by using the apple istructions here:
http://docs.info.apple.com/article.html?artnum=303446
but it didn't make any difference.
I have double checked all wires,I have switched from 512MB to 2 GB and from 2 GB to 512MB three times(!) but nothing has changed:
- when using 512MB fan runs slow;
- when using 2 GB fan is still able to change speed but is running fast more often.
Further more, to test, I have also left disconnected the fan speed cable in the front side, and in such way the fun starts at max speed and runs at fast speed all the time. So it is not a trouble with such connection.
Is that normal this behavior?
Does anybody have noticed any fan speed difference after RAM upgrade?
About BootCamp and XP running fan at max speed, could be that reinstall them could solve the "always on" fan trouble with 2 GB?
Thanks a lot for any help.

I have some updates about the problem.
I was thinking that it was a my fault about some missing setup needed when installing more ram to mac mini.
So, today, I have moved to a local apple center and I have asked them to install the RAM for me... they do, and it happens the same thing: the fun was running very fast quite often under OS X and was always fast under bootcamp-XP.
I have asked them why this happens and if that was normal, but they have no other mac mini with such amount of ram and they never see it before. They suggest me to test it for a week and eventually to give them the mac for a day to make some hardware tests.
Later, back into my office, the noise was too high and too annoying so I have called again apple to explain the situation.
They told me that they have no reports about similar problems, that it should not make more noise when adding RAM. They suggest me to try remove and reinstall better the RAMs or to try different RAMs (I am using kingston kit KTA-MB667K2/2G).
So I have also phoned to kingston support, and they say that it is a strange bahavior, that they don't have reports about that too. They are now investigating the problem and they let me know something in next days.
They also put to my attention the fact that the computer is able to see and work well with the 2GB memory, so the memory is working correctly. They think this is something related to apple hardware/firmware and could be that apple should fix it in next realases.
Unfortunatly, all this new infos and all the time lost for a "simple" memory upgrade didn't solve my troubles and I still cannot use the mac like I need.
So I have continued my tests by changing the kensington Dimms with other 2 GB dimms by Nanya technologies that were installed on my centrino duo notebook.
Mac mini was able to see and work well with them too, now the fun speed is a little bit slowly then using kingston ones but still more fast than with 512MB.
Bootcamp-XP is still not usable due to high fan speed and the high noise. OS X seems to control better the fan speed but it goes high there too for any little thing you do.
So I have made one more test suggested by kingston:
I have started mac mini while only one kingston dimm were inside.
In this way the mac mini was making some less noise that using the two nanya dimms, but it was still to high.
The last test I made was to check the cpu temperature with different amounts of RAM and results were interesting.
Using OS X with 512MB, the cpu temperature is about 33 C while iddle; if I try to start parallels desktop with guest windows XP, temperature goes up to 40 C and the fan is still running at quite low levels.
Instead, while 1 GB of RAM was installed, cpu iddle temperature was 35 C and starting parallels desktop will result in temperature levels till 50 C.
So there was a difference of about 10 C.
While doing these test I have left the mac mini open, so once stopped, I was able to quickly feel the RAM temperature with my finger and it was quite hot.
I didn't try temperature with both 2GB dimms, but I belive it will be surely more high.
So what I am thinking now is that probably apple is aware about higher temperature inside when using more RAM, so the bios starts the mac mini with the fun running faster because it detects the 2 GB memory.
OS X is able to control someway the fun so it is not always running fast (but quite often) while using boot camp with XP becomes impossible due to the fan always at max speed.
I don't think apple's rams could work at lower temperature than kingston ones, so the dubt now is that things are correct in this way.. so intel mac mini with 1/2GB could be a shame due to high level of fan noise... or... my mac mini has something wrong.
Is anybody here with a mac mini and 2 GB of RAM?
Anybody could make some test about that?
Thanks a lot for any help

PowerMac G4 won't power on after RAM upgrade

Hey all,
Had a friend of mine e-mail me with a problem. He recently attempted a RAM upgrade for his PowerMac G4 (sorry I don't have more specifics), he had 2x256MB sticks with an open slot and tried to put in a 512MB stick. When he did this, the computer wouldn't start (hit the power button and it lights up but the machine turns right off).
He tried leaving the computer unplugged for 15+ minutes as well as resetting the CUDA via its little grey button on the mainboard. Nada.
He also tried starting the machine with just the new RAM and putting the old RAM back in as it was ... neither would work.
I suggested it may be the battery on the mainboard, to which he has ordered and it waiting.
I was just curious if there are any other ideas?

when you say bad power supply how did you come to that conclusion...i just had a problem where i attempted to install the ram as per instructions...it caught some sort of flat power strip inside the bay and pushed it into the recepticle..i know of people having problems with the ram seating so i pushed and pushed....and eventually broke the wires...now i have no power. i dont know what the wire was but from the power of deduction i realized it was important....as my macbook is now a brick

RAM Upgrade - Cost?

I'm looking to upgrade my RAM on my 2010, 17 inch mbp (2.53ghz, i5). I have 4GB of RAM, and have two questions. I was told that 8 GB is the max, but have also heard that 16GB is possible. Also, how much would it cost to get this installed? I'm in contact with a friend who said he can do it for $80 flat, but I saw on crucial.com that the 4GBx2 RAM upgrade will cost around $59.00. If I go through crucial.com and just look to install it myself, or have someone else do it, will it be overall cheaper than if I go to my friend? Any suggestions?

Only mechanical thing to worry about is not stripping the screws. Stainless steel on aluminum can be a recipe for disaster. Get a new Phillips #00 screwdriver as gkpurves suggests. When removing the screws for the first time, they may feel a bit tight, since they apply a dab of threadlocker at the factory; hence the new screwdriver recommendation.
When screwing them back in, be sure to use the right sized screw in each hole. Feel the thread catching and don't force: each screw will slide in with little effort if threaded right. If it doesn't go in easy, back it out and start again. If you want to be a.n.a.l. about it, insert the screws in a cross pattern, like when screwing down a car's lugnuts. Tighten snugly but not too hard. This ain't your Mustang's lugnuts!

I was wondering if the laptop L300 - 20D.
Can get a ram upgrade. It has 1024 MB RAM 800MHZ. And i need 1500 MB .

Your notebooks RAM can be upgraded up to 4 GB.
For upgrade you can use follow RAM modules:
512MB DDR2-667 - PA3511U-1M51
1GB DDR2-667 - PA3512U-1M1G
1GB DDR2-800 - PA3668U-1M1G
