Installing extra RAM

I hope someone can help me. When I bought my powerbook I added 512MB of memory which they did in the store for me. I just bought another 1GB so removed the 512 and put the 1GB in its place but now I understand that I can add both, but where is the second memory slot? I saw the 1.67Ghz processor and behind that was the 512 slot which I took out, but where do you store more if you want to? Thanks for any assistance

Sorry for delay in reply but I packed up laptop to take to Apple store – but didn't get there. They are confused too, as the memory slot should be empty – not filled with processor. Here is the info:

Problem installing extra RAM

Hi,
I recently decided to increase my RAM. I have an iMac G5 with iSight ( Power PC ). I bought a memory module from the online Apple Store here in the UK, by clicking on the model ( under Memory ) and selecting the 1 Gb module - 533 Mhz DDR2 SDRAM ( it made no specific mention of the PC2-4200 compliancy but I assumed it was the right one given the route I followed ). It duly arrived and I installed it by following the manual. However, on checking About This Mac the extra RAM was not registering, ie still showing the original 512 Mb RAM. I called Apple Tech Support and we tried a few things like resetting PRAM etc,but no change. Eventually, I was put on to sales and arranged to retunr the module and get a refund. I got the impression by the way the conversation went that this was not the first time this had happened.
So, no extra RAM. Anyone tried to install extra RAM in an identical model?And, if so, did they get their module from Apple? I'm assuming this is nothing to do with the fact that I have a Power PC model and the current models are all Intel?
Any help and/or advice would be much appreciated.
Thanks

Any RAM can be faulty, and I suspect the one you got from Apple was. Go online and Google for PC2-4200 (533MHz) DDR2 SDRAM memory. Kingston is a good brand and should come with a lifetime warranty. Most RAM from sources other than Apple is cheaper as well. The RAM you bought is correct for your model, and make sure that when you instal it, you hear it click into place.
Please post back with results,

Disappointed after installing extra RAM :-(

Hi,
Well, I got the RAM today and installed it. It shows up on the "about this Mac" memory list so I know it is okay.
However, I have to say that I am not noticing much of a difference at all in performance. It's really disappointing. There is no increased briskness in terms of opening programs and I am still getting the spinning ball.
I feel like I wasted $100.00 but am hoping there is maybe some system problem I am overlooking.
I really don't want to have to erase and install.
Any suggestions would be much appreciated.

Kallum,
You did the right thing in purchasing the RAM, I assure you. Look back at your earlier thread, and you will notice that I hinted at the possibility that there may be more going on with your machine than just RAM issues...
I'm afraid that you are facing the possibility of erasing and reinstalling.
This isn't the end of the world, though, and we can get you back up and running in short order. The key will be making a good backup, from which you can restore everything. In fact, it is likely that you will end up taking more time with this, than with the actual erase and reinstall.
Do follow another poster's suggestion that you reset your PRAM by holding down Option-Apple-P-R at startup, and continuing to hold until your hear a total of 3 chimes, but don't be too disappointed if that doesn't help.
Post back with the results of this, and let me know what resources you have at your disposal for making a backup. An external drive is really what you need, but let me know what you have.

Installing extra RAM Tabs difficult to pull

Plastic pull tabs will not pull out existing memory. How hard can I pull, the instructions say 'gently'

The memory eject tabs on my 27-inch iMac do require a fair amount of force. In order to make sure that you don't tear the tabs from the memory slot make sure you pull straight down. If I recall correctly it takes approximately 1/4" of movement in order to eject the memory.

Extra RAM

Hi guys, quick question about the 15" Superdrive Powerbook. Is it easy enough to install extra RAM? Would I have to go to a professional or could I install it myself? Cheers!

Here's the link to Apple's instructions on how to add extra ram:
http://www.info.apple.com/usen/cip/pdf/pbg4/pbg415fw800mem.pdf
You may want to open it up to see what you have now....1GB may mean that you have two slots filled already....the factory 512 and another 512. If that's the case, then you'll need to remove one, or both, to add one or two 1GB cards.

Installing 2x1 Gig extra Ram

MSI P35 Neo2- FR
2 x 1 Gig Ram
Windows XP
Video 8000GT one Gig Ram
Intel Dual Core E8500
Bios 1.8
Newbie --
I am thinking about installing 2 x 1 Gig extra Ram, I understand that Windows XP 32 bit, will only recognised a total of 3 Gig. Does this mean that the system only operates of 3 Gig of Ram, all be it 4 Gig of Ram is inserted?

You could buy 2 x 512Mb modules......
You will not really see big increase in performance for day to day tasks. If you edit photos or do media work then yes you will see speed increase.
On a sidenote:- Did manage to acheive 3.5Gb seen buy XP pro, by dropping to a 64Mb graphics card.....

Do i need extra RAM to install adobe design standard cs5.5

I have an iMac bought mid 2010 snow leopard 10.6.8. I am looking to buy adobe creative suite design standard CS5.5, will I need extra RAM?
I hope not!
I only really need photoshop, illustrator and indesign, so my other question is can I just install these from the package?
Please help anyone!
Thanks.

No, I am saying the three programs that you want to use in the suite, if you are planning on using all three programs (at the same time) then it is possible your system could slow down, then a RAM upgrade will help. Give it a try it may work out okay.
Yes, I know how to backup separate things on to another external hard drive. Just connect the hard drive make sure it is formatted for use as a Mac hard drive. Open disk utility and click on the hard drive at the bottom of the window it will show you the partition map scheme, it should be GUID Partition Table. If not then you should format the hard drive but clicking the erase tab and the selecting Mac OS Extended (journaled) from the format drop down box. If you are going to use the drive to transfer files from Mac to PC then you should select MS-DOS (FAT) the only problem with this format you will not be able to copy file larger then 4GB. Then just open the find and drag and drop folders and files to the external hard drive.

Early 2008 mac pro more beachballs with extra ram

I have just installed and extra 8 gig of ram however i seem to be getting more beachballs hangups than i had before. I have installed the ram in the appropriate fashion but i just get more hangups. I have cleaned the system using onyx and all the caches are clear but i still get hangups. Please help

I see more trouble from people using Onxy. Coincidence?
Does it work with just the new RAM?
They are fully Mac Pro FBDIMMs with large heatsink and in paired slots?
Have you run Apple Hardware Test and Memtest (or Rember) with them?

What do I gain by installing more ram ?

Hi !
I would like to know what are the advantages of installing more ram on my powerbook ? Would installing an additionnal 512 mb ram or 1gb ram speed up the idvd compression to dvd ? More generally while I gain performance on game graphics or video compression ( which takes quite a long time on a powerbook )?
thank you

Hi Yanis,
No performance gain in graphics speed, no, but
a smoother and quicker computer use in everything that uses "hard disk accessing" while running a task.
Simplistic answer:
The more RAM is available, the less tasks need to use Virtual Memory.
And RAM is much faster than VM, too.
If you often hear that your work uses hard disk accessing, then you'll be happy with extra RAM.

Satellite U200-181 - How to add extra RAM?

Hi
I've enjoyed my U200-181 very much, but would like to have some extra RAM in addition to 512 Mb installed by default. How can I do that?
How many SO-DIMM slots available? Are there any disassembly instructions?
Thanks in advance

changing the memory is very easy.
1. pull off the black strip above the keyboard (it just snaps in place)
2. remove the 2 screws
3. pivot keyboard forward being careful not to damage keyboard cable
4. remove 2 screws on big metal plate on the right.
5. remove plate to expose 2 x ddr2 200 pin sodimm slots.

Problem installing 512mb RAM in Macbook Pro.

Hi,
I hope someone can help me, I have checked other posts and nobody seems to have the exact problem that I have after installing RAM.
I installed a Crucial 512mb module in my Macbook Pro which already had a factory installed 512mb module in one slot.
First time the Mac started up ok but it did not recognise that extra RAM had been installed. I reseated the crucial module and the Mac would not start, just a pulsing power light and a black screen.
I installed one module at a time and the Mac booted correctly with both the Crucial Ram abd the RAM it shipped with.
When I put in both Modules it will not boot, I switched the slots and made sure that modules were inserted correctly but no joy.
Sorry for being so long winded!
Macbook Pro Mac OS X (10.4.6)

Thanks guys,
It just seems odd that both modules are working correctly when they are installed on their own and there is no boot when they are installed together.
As you stated it may be that the specs are different but I checked and all the info seems the same.
I'll just go ahead and send it back to Crucial for a replacement.
Thanks again.

Extra ram cause restarting problem on g7-2325dx

I have g7-2325dx with 4gb ram, and when I attach extra 4gb ddr3 sodim ram from best buy, the laptop shows error messages leading to restart. When I restart it, it will work for about 5 minutes and error message will show up again restarting the laptop. So I decided to get rid of it. Is there anyway I can put this extra ram without causing error messages?

Hello Chris,
As mentioned in post #2 (by Pepe) try updating your BIOS first. Btw Could you let me know the error message you were receiving? Also did you try installing the 4GB (new*) memory alone in the slots and did it boot up if you have tried?
Moreover, in order for your laptop to recognize 8GB of memory you need to have a 64Bit of operating system as 32Bit recognizes a memory of 3 - 3.5GB only.
My theory is either the 4GB module maybe defective or it maybe due to the use of generic brands. Sometimes some Generic (OEM) brand memory will not work. In case you need to test the memory, then you can test it using memtest86 (click here).
You can send back the memory to bestbuy and instead try buying from crucial, memorystock, corsair, G skill, OCZ. Kingston.. you can find the memory in the above websites.
Following is the exact specs of the memory which your system supports - 4GB DDR3-1600 MHz, PC3-12800 SODIMM (HP MFG # - H2P64UT#ABA)
Good Luck with the upgrade
Best Regards,
John

Windows 7 and extra ram

I want to share an interesting experience with fllow iMac users.
I bought a reconditioned mid 2010 iMac 27" a couple of months ago. It came with 4gb of Ram but I decided to mac out to 16gb with four pieces of 4gb Transcend which worked fine. I also upgraded to Lion. With this config, I was unable to install Win 7 Ultimate 64, Win XP etc. (All original full versions). I then tried to revert to Snow Leopard but failed. I was on the phone to the nice Mac folks and they suggested I lug this 27" back to a dealer here in Hong Kong which is a nightmare with all the traffic. I was preapring to do this and thought I better put the old Ram back in so the techs don't fault me for using the wrong hardware. So I replace the ram and then have one more try at reinstalling MacOSX and it worked. I then added Win 7 and the whole family of Office Software. This was going fine. I then decided to add the extra Ram and then Win 7 would not boot again - MAC OSX was working fine with all kinds of combinations of RAM. I tried to repair it and inserted the original Ram but it did not work. I am now thinking of trying to add one piece at a time and see what happens.
The thing I can't work out is why MAC OSX accept the ram and not Win 7.
I saw a lot of old posts about this but nothing current so I thought I had better put something here for folks to consider.
If you have a similar iMac and upgraded with OEM (non MAC) ram and you are running fine let me know. Perhaps Win 7 in bootcamp can only accept MAC ram or needs new drivers for OEM ram.
If you know about issues and solutions, please share.

Hi and welcome to Discussions,
are the 8GB shown and used in OSX ?
Have you tried running the Apple Hardware Test yet ?

PSE 11 not recognising extra ram on an iMac

I have an iMac which had 4 gb of ram. Photoshop defaulted the usage to just under 3 gb. I installed another 8 gb of ram but PSE fails to recognise the extra ram
so I can only get it to use 3gb. If I reinstall will it recognise all my ram? Will I still have all my photos on the organiser?

Hi smudger1939,
PSE won't recognize the extra RAM after 3072 MB. As it's the highest which a 64-bit application can use. So even if you install even another 16GB of it. I won't be able to use that one. However, it's a benefit when you are using several applications parallely. The extra RAM will be used by other applications, and will not hamper your PSE performance.
So if you want to increase the performance of PSE, reduce the history states. You can also refer to this kb article for the same:

HT1270 Where do i buy extra ram memory? and prices

I need to buy extra Ram memory for my new laptop, from 4 gb I want to go for 8 g. Where do I buy it and who installs it?
Thanks

OWC and Crucial are the best sources for Mac compatible RAM. Process are on their web sites.
RAM can be user installed. Look for installation videos on the OWC web site.
Note that retina MBPs cannot have RAM upgraded.
Ciao.
