1.5ghz 15" PowerBook RAM - 1gb Question

I just ordered a gig stick of the Samsung RAM for my powerbook. It is an older powerbook purchased about 8 months ago. Right now I have 2 sticks of 256 in it. My question for everyone is which slot I should put the gig stick in. Also, I plan on leaving one of the 256 in there to have a total of 1.25gb. Has anyone done this and/or had any problems with this configuration?

Well, yes if you're planning to replace the other 256 stick I suppose it might be helpful to swap them over now, though honestly it's no big deal whichever way you decide to do it. I understand your nervousness, but I can honestly say this is probably the easiest RAM to change of the 5 computers I've upgraded. The most important thing is to get yourself the right screwdriver then just look at the opened up bay in conjunction with the printed-out instructions until you're happy you know what's required. Also make sure you're happy which side of the memory module is "up" - look at the one you're about to take out first.
I found the Apple document as good as it needed to be. I'm sure you'll be fine - just remember to "discharge" yourself by touching something metal before you start. Good Luck

PowerBook 17" 1GB 1,6 GHz G4 does not show logging window

I have a problem, and it's strange.
I can access the PB with FireWire, start another mac via FireWire from the installed MacOS X (10.4.1 after setup) without any problem.
Verbose mode and single user mode as the open Firmware is still possible.
Reset the paramter rams and the vram... no change.
Boot from CD comes with the MacOs installer mode, if a use the MacOS Tiger DVD for startup.
But booting from the internal, fresh setup harddisk will lead to a MacOS splash screen on the blue background, were in the window the blue progress bar comes from left to right.
This progress bar moves about one fifth of the lenght, get stuck and the system freezes...
Anybody a clue, what might help?
Anything, I can try in single user mode?
The PB came from a customer, and someone tried to delete it. He removed the harddisk and put that into a harddisk erease tower to delete all data... that's what he claimed.... and that's it. I am able to partitioning the harddisk and set it up, but I am unable to boot from the harddisk the PB. I can boot another mac via firewire from the harddisk, but not the PB itself...
Now I am stcuk.... any guess would be helpfull.

Hello Greg, hello Jim,
I was a week on autumn vacations, so I had plenty of time. I was trying to do.
I reboot from the original Tiger DVD, used Disk Utility from the install DVD and overwrote the harddisk 7 Times with zero. I did no partitioning, but renamed the disk and start setup.
Setup runs, as ever, with now failure. Reboot, and the system hangs....
I tried Apples Hardware Test, but the test cannot repair the harddisk, because of a failure message poping up, that a subsystem process cannot be executed, and the repair failed.
So I do not realy think, that the harddisk has an error, it seems different, because on a harddisk error, a format with zero would not perform that well, as the installation would not run that smooth...
I have done now serveral installtions tries, but all end up with the blue progress bar in the Mac OS X screen hanging at about a quarter of lenght and doing nothing further.... even if I wait for more than 12 hours...
I never have seen such a thing before.
Hello Steffen.
I do not really see a question in your new info, but, based on the totality of both your posts, my two guesses are as follows:
(1) This disk drive is either faulty or connected improperly. Alternatively, it seems possible to me that it is an incompatible drive that has been installed in this Mac.
If I could not find a way to tell whether one of these conditions exist, I would test by replacing this drive with a known working drive that is known to be compatible with the PowerBook.
If I did not have access to a working, compatible drive, I would ask an Apple Service Technician to fix the problem.
(2) If this drive is compatible with this PowerBook, and if it really "can boot another mac via firewire from the harddisk" after OS X has been installed, there must be something wrong with the PowerBook's connections or other hardware.
I would test this by installing the problem hard drive in a different PowerBook 17" 1GB 1,6 GHz G4, to see if it works there. If so, you know the problem is with the PB rather than the drive itself.
If the problem is with the PowerBook hardware, unless I could troubleshoot and repair the problem, I would ask an Apple Service Technician for an estimate of the cost to correct the problem before undertaking repairs. It is possible that this will be a costly fix.
(3) Please let us know what happens. We will watch for your status update.

Another RAM upgrade question

Hi everyone,
I know there seems to be lots of RAM upgrade questions here but hey thats what forums are for.
I'm looking to upgrade my macbook's RAM it's currently got 2GB (2x1GB)
Is it possible to purchase 1x4GB and put that with one of my current 1GB sticks to create a total of 5GB?
I would be interested to know if this is possible or if anyone has tried it.
Thanks in advance
Scott

This will work if your MacBook is late '07 or newer.

Desktop RAM upgrade questions

Hi, I have hp elite m9000t series desktop with 2 GB(1 x 1GB) ram and as per the specs and research in hp website it can support to 8gb. RAM is of DDR2-SDRAM (pc2-5300 / 667 MHZ) type. I have 2 more slots open, so guess that can add 4gb(2 x 2gb) of ram. Question is 1) do i need to buy the sam ddr2 667 mhz ram or can i go to higher speed models? 2) is it compatible to have 2 slots with 1 gb each and another 2 slots with 2gb ram each? 3)what is the recomended RAM for window7 better peformance? i am planning to install VMware to do other OS like linux, etc.. given that i may need more RAM. Please suggest me on the memory upgrade..I am seriously looking towards windows7 release date, i am very much disappointed with vista, cant wait for windows 7.
btw, i am planning to upgrade to 64bit windows 7 professional, currently i am running with home premium 32bit.

It's best to install RAM which is just like the one you have right now, i.e. pc2-5300 / 667 MHZ. In fact, I would recommend using RAM from the same manufacturer as the one that is currently installed. Each slot should have the same amount of RAM. So I suggest you use 1+1 or 2+2 rather than 1+2. Since you'll be using VMWare(hope your processor supports Virtualization), I suggest you go for 2+2.
Make it easier for other people to find solutions, by marking my answer with \'Accept as Solution\' if it solves your problem.

All things being equal, does 4th gen quad core i7 (2.5GHz) need more RAM than 5th gen dual core i5 (2.7GHz) for same tasks?

Bought mid/late 2014 15" MBPr with the i7 2.5GHz and 16GB RAM. I'm within 2 week exchange period at Best Buy, and thinking of switching to 2015 13" MBPr with i5 2.7GHz and 8GB RAM for battery life and weight, and they don't offer the upgraded 16GB RAM option for any 13" models.
Needs to be Best Buy because of gift cards
Use docked at office 75% of time vs 25% out of office, so portability and battery life are nice to have but not as important as if I had 8 hour flights on weekly basis
See appeal of having 5th gen i5 in 13" vs my 4th gen i7 that will be updated this summer
Not a gamer and don't use Final Cut or other video editing, but I tend to leave several applications open and usually have between 1-3 GB free RAM of the 16GB total at any time according to my Memory Cleaner readings
Therefore, worried that 8GB is a non-starter as simple math says that I would have shortfall of 5-7GB RAM based on above readings, but wondering if dual core i5 will use RAM more efficiently than quad core i7
Any help greatly appreciated!

Also to note, would like this to last 4 years, which was reason that I bought the higher spec'd model even though I don't run games or video editing

I have a 2008 mac book....with 1GB 667hz DDR2 RAM 1GB each....I want to upgrade it with DDR3 Rams 2GB each, it is possible?

No, the two RAM types are different, and the architecture has to specifically be able to interface with it. You can upgrade to 2x2GB of DDR2 memory, for a total of 4GB.

Powerbook G4 15in 1.5GHz Dead Lower Ram Slot

My Powerbook G4 has a bad lower Ram slot, but the problem is intermittant. If I put both 512mb ram in and start up, sometimes I get the 3 beebs and sometimes it will boot and show a full 1gb ram but locks up moments later.
I've been running on 512mb and it is not fun!
I can not afford a new logic board or a new mac. I am a web designer and need my PB for work.
How can Apple not Recall these machines and fix them?

Did the 2 RAM modules come with your Mac? Have you tried swapping the RAM modules to opposite slots and do you get the same failure in that slot? Make sure the modules are securely connected in the slot.
To eliminate RAM modules being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.

Upgrading from powerbook g4 to new mbp 15.4 i7 - ram & hardrive questions

Hi,
I am a graphic designer and I am currently using my powerbook g4 and it is running VERY slow, its time for an upgrade. I have decided that I would like the mbp 15in i7 with the anitglare display upgrade. The two other upgrades I have been trying to figure out if it is worth the money is the 4gs of ram to 8gs ram for $400 and the 500GB Serial ATA Drive @ 7200 rpm for $50.
I mostly use indesign, illustrator, photoshop and dreamweaver. I will also be updating my cs2 to the new cs5. I tend to run multi programs at once. I dont know how much a difference this $450 will make for what I do. Does anyone have any advice on whether it is worth it or not.
Thanks!

Welcome to Apple Discussions.
My recommendation would be to upgrade the internal HD but wait on the RAM upgrade. Here is my rationale, first try the new machine with 4GB and see if the performance is acceptable to you. If it is you are ahead if it isn't the RAM is user upgradable (and will NOT affect the warranty), the job takes 10 minutes at the most. Also RAM is currently expensive, however third party RAM is less than what Apple charges, not dramatically but about $40.
On the HD you are getting increased HD performance for a modest fee however the applications you will be using are not disk intensive so the performance increase will be very small. If you did decide to upgrade the internal HD at a later date (which also will not affect the warranty assuming you do it per the instructions) it would cost more than $50.

Roger

Powerbook RAM in MacBook Pro

I'm sure this is probably not possible, but worth a shot.
Can I transfer the 1GB RAM chip in my Powerbook G4 15" 1.5Ghz to my new MacBook Pro 2.0Ghz?

If the mac does boot by some strange change you will be totally downgrading the performance of you computer as both chips will need to run at the speed of the slower chip from your PowerBook.
It is simply a bad idea.

12" powerbook ram upgrade

I have a 12” powerbook G4 with a 1.33GHz processor and have noticed that programs have been running a bit slow on my 256 of factory installed ram. I have one slot available for adding a new stick and am not sure if it is worth the money to put in 1Gb or just triple what I have by adding in 512. A gig stick is 3-4x the cost of the 512 & I don’t run any major major memory burning programs. Any advice? Thanks

Problem with RAM 1GB and SGA

I have RedHat 6.1 and Oracle 8.0.5 on Dell with 2xPII and 1.5GB RAM, kernel 2.2.14. When I set in kernel option 2GB RAM, make it, I can set max 70MB shared memory pool in init.ora. With 1GB RAM in kernel, I can set 419MB shared memory pool (its max from standard shmparam.h).
Question: How I can set > 419MB shared memory pool with 1.5GB RAM?
Thanks for all answers.
Jirka

The problem is the default address for mmap, you can solve the problem changing the SGA address, a good choice is 0x40000000, the procedure is:
Shutdown all your instances
cd $ORACLE_HOME/rdbms/lib
genksms -b 0x40000000 > ksms.s
make -f ins_rdbms.mk ksms.o
make -f ins_rdbms.mk ioracle
I can get up to 1 GB SGA in my 2GB machine

Macbook C2D late 2006 RAM upgrade question.

Hello everyone,
I have a late 2006 Macbook and am planning to upgrade the RAM from 2GB to 4GB.
From what I understand, my motherboard only supports 3GB, and I'm ok with that.
My question is:
Because 1GB will be left unused, will the OS use any of the extra GB towards my Intel GMA 950 GPU's 64MB of shared memory?
I know the machine performs better graphically with with 4GB of RAM rather than 3, I was wondering if that extra GB of RAM is just used my my GPU rather than by the computer?
Like, will I get more then 64MB of shared RAM?
Thanks for reading, and I hope someone here has the same configuration as me, has added the 4GB, and could tell me if there is any GPU upgrade with the 4GB.

No, the GMA 950 shares the 3 GB. Some have reported after testing that the MacBook is actually using 3.3 GB.

This is from the specs.
+Memory available to Mac OS X may vary depending on graphics needs. Minimum graphics memory usage is 80MB, resulting in 944MB of system memory available on 1GB configurations.+
The 64MB is a baseline because of the GMA 950 spec. The MacBook actualluy uses more and more is assigned as needed by the graphics.

HDD/RAM upgrade question - 400 mhz sawtooth

Hello!
My Sister has a Sawtooth G4 - Well, I believe it's a sawtooth anyway. I don't know for sure, so I'll post a bunch of specs:
It's a 400mhz model, early 2000. It shipped with a 10GB HDD, and 128 RAM. I believe it also has a 100 Mbps Ethernet. It has a DVI and VGA monitor video card, but i'm not sure the Video RAM level. It has an internal FW 400 port as well. The internal Airport card is shot - er, maybe the extension.
It has major issues with the system - and it seems to stem from a botched OS 9.2 install. It's running 9.1, but with trouble. For one, I can't open the extension manager. For two, it's slow, and acts funny.
Well, I thought i'd be nice, and try to get the G4 working for my Sister. It seems that it may require an Clean install of OS 9.0. Oh well, I can do that easily enough. However, before I go through all that trouble, I'm contemplating upgrading the hard drive (at least). With only 10GB, it's not very useful for iTunes, Photoshop, or our old OS 9 games - things she'd like to have.
I looked at the specs for the Mac at:
http://www.lowendmac.com/ppc/g4saw.shtml
It takes an 3.5 inch Ultra ATA drive? I've seen those around - and a 60GB drive or so is becoming pretty cheap. (I've seen 80G for under $50) I just figured i'd ask if anyone has tips on what to buy, how to install it, and Particularly if I need any special adapters for the G4. It does have a slot for a second internal HDD. I've also heard that a fast, second internal HDD can overheat the computer - is this a common issue I should be worried about?
The same questions go for the RAM. I'd like to add at least an extra 128MB, but I'm not entirely sure what to get. The above site mentions that it uses PC100 SDRAM in DIMM mode? Hmmm... I'll have to look around.
Please excuse any silly questions, I'm just far more familiar with more current systems, and it's 1 AM
Thanks,
Dan
PS: It looks to have a slot for a floppy drive under the DVD-ROM drive. I have a bunch of files on our OLD PowerBook 5300 that i'd like to move - but I need a floppy drive. Our old external USB floppy drive is.... very dead. The external floppy drives i've seen at stores seem to be pretty expensive, but internal drives are still fairly cheap (some under $30). How hard would it be to find/buy/install a compatible floppy drive? What format would it need to be? If such an upgrade runs over the $40-50 that a new USB drive costs, it's not really worth it.
15" Powerbook G4 (May 2005 ed), iMac DV (9.2.2) Mac OS X (10.4.6) 1G Ram, 192 (iMac)

Wow, thanks again!
I figured out that this is the AGP graphics Sawtooth - not the Yikes model. Where do these names come from?
As per upgrading to OS X - we have a G5 which she can use, and a XP box - which is down with the flu for the third (or fourth?) time. Therefore, the G4 will stay OS 9. She just wants to have a reliable machine that can play DVDs and music, and play some of our old OS 9 games. It's not intended to run any new programs, just the old ones that she can't run now. When I mentioned photoshop - it's a "Limited edition" of version 5.0 - and it's far, far, FAR more reliable on the G4 than on our 2-year-old XP box, despite the G4 running 9.1 with a wimpy 128 meg ram!
The main reason for upgrading the HDD was to make it more practical for games and MP3s - via iTunes 2! It won't play AAC, but it plays MP3s fine. She has at least 8 Gig of music - too much for a 10G drive! (Even half of it leaves precious little expansion room)
I'm watching for a "small" HDD - it seems that our local Fry's is no longer selling anything smaller than 100G - which was $100! Or perhaps they were just sold out at the time. I'll keep an eye out for another sale. In fact, asking my friend for an old drive is a good idea. They have parts from at least a dozen old windows and linux boxes floating around - so they likely have a drive or two. If it's a used HDD, loaded with Windows (probably 95-2000), will it confuse the system before re-formatting?
As per RAM:
I'm quite aware of the lack of RAM. However, I'll have to watch for sales! I'm not aware of any "Mom and Pop" stores close by, although that's a fantastic idea. A PC 133 128 MB card runs $40-50 at the local computer stores, but only $15 at OWC! Therefore, if I don't find suitable RAM locally, I'll order some. I wouldn't mind an extra 256 (or 512) for my iMac either.
Speaking of iMac - I've determined that it's the iMac DV Special ED from March 2000. (400mhz, originally 13 Gig Drive - now 60, 9.2.2) The question is whether or not it maxes out at 512 MB or 1 GB of RAM. One of the Apple support sites I found ( http://docs.info.apple.com/article.html?artnum=58007 ) said that the slot loading iMacs max out at 512. It makes no distinction between any slot loading iMac. However at http://www.lowendmac.com/imacs/dvse.shtml, it mentions that this model specifically can accept 1 gig of RAM. I'll assume that the Apple article is correct, but I'd love to get a full 650 MB if I can! (I'd love to add a 512 to the 128 I have now)
It's amazing, really - after 4 years of constant use, a hard drive motor failure (hence the 60G HDD), and a year and a half burried on a desk, the iMac is becoming more handy by the day. It's good at capturing the Video and audio from say, Halo, while my PB's too busy to run anything else (via S-Video and audio through our DV cam). It makes a great DVD player, an iTunes Jukebox, and game machine - most of my games are still OS 9. To top it off, it makes a great wireless base-station for my Nintendo DS at school, where there's no WiFi! With 30 gig of space left on the HDD, it has plenty of room for whatever I want to do with it. Guess you can "teach and old dog new tricks!'
Well, I guess this means my question is answered for now - once I find the things I need, i may have some more questions, Thanks again!

Powerbook 12" display question

Hi all
I recently bought a 1.5 Powerbook computer from someone. I was told before I bought it; that the screen was dim and you can faintly see things in the Finder. The person that I bought it from told me that she took it to the apple store and they said that it was the inverter board that was the problem.
After I bought the computer, I took it home and started to troubleshoot the problem. Well, the display is definitely faint. However, about a third of the display (from about the middle to the lower part of the display) is completely black.
I haven't hooked up the powerbook to an external monitor. If I assume that the person who I bought it from told me the truth about the Apple Store looking at the computer, that they would have done that to eliminate that possibility.
My question is this. Since the lower portion of the screen is completely dark (and the upper half is faint), would the problem be the inverter board or the actual display?
Also, I have another 12" powerbook (it is the 867 model) that is disassembled at the moment. Would it be possible to take the connector from that display and somehow put it in the 1.5 model's logic board in order to see if the display would come on?
Another question: if it is the inverter board and not the screen, would I have to take the whole display out in order to get the inverter board? I noticed in the powerbook-medic's video take apart guide; that he only goes as far as to removing the display in his video and doesn't show the removal of the inverter. I know that after you take out the LCD, you have to disengage the airport part from the inverter from his take apart manual. Any thoughts on this for advance precautions?
Thanks in advance for your time in reading this.

Well, so much for the previous questions
Anyway, I decided to buy a used display on Ebay. The person I got it from has 100% feedback and has done many auctions.
In any event, after taking the powerbook apart once again, I put in the new (used) display in. I also put in my hard drive from another aluminum powerbook machine (12" 867). When I booted the machine, I didn't see anything on the screen. All I heard was a low long beep for a couple of seconds.
I decided to put in another RAM chip and the original hard drive from the 1.5 machine. I started up the machine and noticed that it was doing the SAME thing that it was doing with the other screen. It was giving me a faint desktop.
I took the machine to work and tried it again with an external monitor once again. It works with an external display.
So, before I email this woman and tell her that she gave me a display with a bad inverter board. Would it be possible that there is something else wrong other than the display.
BTW, I did the P RAM thing and reset the power manager.

Mac Pro 8-core RAM Configuration question

I know there is a lot of questions about Ram fro Mac Pro on this site but I got a brand new Mac Pro 8-Core today, didn't buy RAM from Apple because of the obvious reason, 1GB (2x512mb) is what I have right now. I am interested in upgrading to 8GB...SO... my question is, What is the best RAM configuration for my Mac Pro? Read the list below. Keep in mind that I am a web/graphic designer so Photoshop is one of my main tools along with Aperture, DreamWeaver, Flash, Final Cut, Illustrator, etc...
My options:
2x4GB
4x2GB or...
8x1GB ???
Please advise. Thanks in advance.

2GB X 4 is best due to the combination of benefits of performance, cost, power consumption, thermal profile.
Performance: groupings of four FB-DIMM allow 256 Bit memory access
Cost: 2GB FB-DIMM are less expensive and more generally available than 4GB
Power consumption: 4 FB-DIMM use 1/2 the power of 8
Thermal Profile: fewer FB-DIMM generate less heat and allow more airflow
