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,

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.

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.

Problems installing new RAM

Hi guys,
I have a 17" G5 imac (built in isight) i recently bought a 2gb RAM chip for it. I have tried to carefully follow the instructions to install it, but the chip does not seem to "click" into place as suggested in the manual and if i close the machine up again the new RAM is not recegnised. So, my question is, am i being too gentle with the chip? or is there some special trick to this? i installed ram on my macbook easy enough before however this attempt is proving difficult. anysuggestions would be really appreciated.
thanks

You really need to force the stick in, I use both thumbs and push like mad!

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.

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:

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.

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

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.

Problem installing RAM (flashing power light, etc.)

Hi everyone.
I have been spending the last 2 hours trying to install this OCX Ram (2x1GB) into my PowerMac G5 Dual 2.5. Before installation, I just had the 2x512 Apple memory.
After installing the RAM following instructions from Apple's website, I turned on the computer and the power light just flashes twice, pauses, flashes twice, pauses, etc. I read that this could mean either the RAM is bad or installed incorrectly. I tried repositioning the ram in several different slots, but to no avail. Below is the link to the RAM from the site I bought it from. It seems like it would be compatible to me (A user review claiming to have used this model in his/her 1.8 1st Gen G5 claims it works fine).
To make matters worse, I took the new RAM and out and put the original RAM in their original positions and I still get the double blinking light! Can someone please help!

The memory you have has heat spreaders, which you shouldn't need, not that it is causing problem.
It isn't Mac compatible, lacks SPD the Mac needs usually.
You need to reset-nvram when changing hardware configuration usually. Manufacturing changes so even Crucial sometimes runs into problems with compatibility. Where two batches don't work together.
If you have a G5 2.5DP, memory based on someone else's system, with slower fsb and different specs?

Problems with Installing 4GB RAM on mid 2007 iMac

I ordered 2 X 2GB sticks of PC2-5300 DDR2 SODIMM RAM for my Boss's mid 2007 iMac from Crucial.com. Well they arrived a few days later and today I have been trying to install them for a few hours now without any luck. I have installed new RAM about 5-6 times without any problems before on different MacBooks and iMacs. After this install I plugged back into the wall and hit the power button, the iMac made a little noise (internal noise) then nothing, just a blank screen. I thought maybe the RAM was bad so I inserted 2 other chips (we ordered 4 X 2GB to upgrade 2 iMacs) and still no luck. After making sure the iMac would boot with the old RAM (which it did), I tried installing 1 X 1GB with 1 X 2GB and it booted up perfectly. I did this with all four 2 GB RAM chips to make sure they all worked and they did. Each time I successfully booted, I went to the system profiler to make sure it recognized 3GB of RAM and it did. So my question is why is this mid 2007 Aluminum iMac not working with 4GB of RAM, but it works perfectly with 3GB? Thanks in advance, sorry for the long question.

+It seems to me that it is not just a problem with the RAM but with the imacs themselves.+
How does this make any sense when one considers that Apple successfully specified, produced, sold and delivered all three iMac (mid 2007) models with an optional 4GB of RAM pre-installed?
In addition, Apple has, without issue, sold large quantities of that same RAM online and over-the-counter for customer upgrades. Much of all that 2GB, and the latest 4GB RAM, as usual, has been manufactured by Micron, the publicly owned U.S. manufacturing company parent of the Crucial direct sales division. The same type of RAM was also being provided to Apple by other manufacturers.
I received my two orders of upgrade RAM from Micron/Crucial even before I had purchased my 24-inch iMac, and it's worked great ever since I installed it. I also installed the second half of that order into my current MacBook, purchased a month after the iMac, and it's also been working great ever since. These are certainly superior Apple products.
Obviously there has been a change in RAM manufacturing design at Micron, probably due to their change-over to the costly, challenging high-tech 50nm and 40nm manufacturing technologies, and it is nothing more than Micron's problem.

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.....

It shuts down? Doesn't restart?
What is the difference in environment from the shop and your place?
Shutting down is normally - still - a sign of the processor turning itself off to protect itself. It's not alive long enough in BIOS, to make you see the temp?
I doubt you keep the computer in the cupboard, but it should anyway have about 50 cm free space in every direction (except downward of course).
Fredrik, The difference between home and shop, I keep the PC in a PC stand at ground level. I could improve its position slightly however, it has been sighted there for aroung eighteen months! The shop guy didn't seem overly concerned by the 49c temp, (he thought the fan was ok) which increased to around 56c with 1.5gb ram installed. When i tried to get into bios I was probably too late hitting delete key has it went to windows scan! After the problems I'd had last week with my original hard drive I didn't want to take any more risk's! Its seems obvious the cpu temp is affected with the extra ram, any ideas?
Thanks Pete

Installed 4GB ram, but comp only reading 3GB?

I just upgraded my 2.4ghz MBP from 2 to 4GB ram (Kingston DDR2-667 2x2GB cards). The computer reads all 4GB (in the system profiler), but when I open a program like AFTER EFFECTS, it's only using 3GB.
Any ideas why or how to fix the problem? Of course I got the extra ram specifically for programs like AFTER EFFECTS and FINAL CUT, so it'd be nice to know that i'm getting my money's worth!
thanks!

The computer reads all 4GB (in the system profiler)
So you DO have 4 GB RAM installed OK.
when I open a program like AFTER EFFECTS, it's only using 3GB.
Not all your RAM is available for an application to use; your video chip, for example, uses your system RAM.
