Another question about upgrading RAM on G4 iMac

I know that there are numerous threads on this forum about upgrading RAM and I am sorry to have to open another one but, having read many of them, I am still confused!
I have unopened copies of Leopard and ILife 08 that I am planning to install on my 17-inch 1GHz G4 iMac with 768 MB of RAM (256 MB in the factory slot and 512 MB in the user accessible slot). I know that this model does not support all the functions of these programs but I am currently running Panther and the very first iLife so I think it's time for an upgrade!
Apple states that this model supports up to 1GB RAM so I have been thinking that in order to get the best out of the new software I should upgrade to 1GB RAM. My questions are:
1. Do I need to upgrade or is the existing RAM of 768 MB likely to be sufficient?
2. If I upgrade, how easy is it to add RAM to the factory slot? I have searched but can find no instructions on this here or on the Apple website which implies that this is not recommended.
3. Several threads on this forum seem to suggest that, in order to avoid having to mess with the factory slot, it is possible to put 1GB RAM in the user accessible slot and leave the factory slot well alone, resulting in total RAM greater than the maximum recommended by Apple. Is this correct or have I misunderstood?
Thanks in advance.

1. Do I need to upgrade or is the existing RAM of 768 MB likely to be sufficient?
That will probably be sufficient. You could always install and run both Leopard and iLife '08 and see if you feel that they are working OK before buying any RAM.
2. If I upgrade, how easy is it to add RAM to the factory slot? I have searched but can find no instructions on this here or on the Apple website which implies that this is not recommended.
Apple does not post the directions because this is not considered something that a user can do by themselves.
You can see the process at www.xlr8yourmac.com/systems/iMacg4/imacg4takeapart.html

That is correct. You could replace the 512 MB in the user accessible slot with 1 GB to provide a total RAM of 1.256 GB.

ANOTHER Question about my iMac G3. Mac OS X and RAM

Hey, I have ANOTHER question about my iMac G3.
I know that I'm supposed to have the latest firmware updates for my iMac G3 running OS 8.1, which I do, but I read some where these firmware updates could only be updated if you're running OS 9.2. Yet when I run the firmware updater, it says my firmware is up to date. I just wanted to make sure this was correct because I just ordered an OS X 10.2 CD today, and I don't want my mac to be "dead" when I install it.
My next question is how much RAM can my mac hold. It's an iMac G3 with a 233 mhz processor, if that makes a differemce.
Again, thanks to the people who have helped me with my first Mac.

hi there--
unfortunately you require system 9.1 or 9.2 for the required firmware update 1.2 for your computer http://docs.info.apple.com/article.html?artnum=86117. so you'll have to install that if you want to install 10.2. it may work for you for a little while, but then you could possibly lose all your information. so i wouldn't advise attempting installing 10.2 without the correct firmware.

Another Question about RAM

I bought my laptop in December of 2009.
13" MBPro.
I have been curious about upgrading RAM since that would be one of my only ways to improve performance. I am slowly adding to this computer so I need to improve it where possible.
I saw something about the "10%" page-in and page-out idea.
My laptop was rebooted earlier today but... as of right now...
Page-In: 474.6
Page-Out: 305.3
Would it be worth it for me to upgrade the RAM??
Any input is appreciated!

Page-outs should only be 10% or less of Page-ins - if you're seeing equal values then yes you need to add more RAM.

Question about upgrading iTunes multiple computers with shared library

Greetings,
I have a question about upgrading to the current version of iTunes.
Currently, my household uses 3 Mac computers (2 Powerbook 17in laptops and a Mack Mini). We are all (currently) on system 10.4.11 (with iTunes 9.2.1). Between the 3 computers we have a shared iTunes music and video library on a networked high capacity hard drive.
We recently purchased an iPad. In order to make it easy for updates and to use media from our iTunes shared library I decided that we should upgrade the systems on our home computers to Snow Leopard. I have ensured that all the computers have at lease 2 Gb of RAM and adequate hard drive space.
The only possible problem I see is that one of the Powerbook laptops uses the old Motorola processor. (This is one of the last Powerbooks to use that processor.) I don’t think this computer can be upgraded to Snow Leopard.
My question is, if I upgrade 2 of the computers (and iTunes in the process), will I still be able to access the shared iTunes library using the older computer with the older system and iTunes? Will the upgrade process change the iTunes library in such a way that the one older computer will no longer be able to properly access that library?
Are there any other problems I might encounter having a mixed system/iTunes environment?
Thank you,
Tim

Just a thought. Should I somehow open iTunes on MBP2 using MBP1's Library file??
both Macs can access the same library file, however, only one at a time !
to do that, you would ideally have the entire iTunes folder (not just the iTunes music folder) on the external. then, on one Mac after the other, launch iTunes while holding the option key, click on +choose library+ when prompted, and select the iTunes folder on the external.
or, you could have two separate libraries and keep those in sync using third party tools such as Syncopation, TuneRanger or SuperSync.
for purchases from the iTunes store, you could set up _*Home Sharing*_ - it can be configured to automatically transfer new purchases to home shared libraries.
Can I create a script to have MBP1 always save the iTunes Library file on the shared hard drive?
no need.

Several Questions about upgrading APEX

Hello,
I a several questions about upgrading APEX.
I want to upgrade my APEX 2.0 to 2.2 and hopefully in a few month to 3.0.
Is there a How To about upgrading APEX?
What would happen to my applications?
Would there be any problems about the applications when the APEX version is upgraded to another version?
Thank you,
Tim

Tim,
Yes there is (detailed) upgrade documentation provided with the upgrade itself, which you should definitely look through. The 2.2 and 2.2.1 releases are currently available here -
http://www.oracle.com/technology/products/database/application_express/index.html
You applications will be 'upgraded' as part of the upgrade process (i.e. they will continue to work with the new software once the upgrade is complete).

Question about upgrade and original iPhone

There might be other thread already, but have a question about upgrade to 3G.
I have the original iPhone and have upgraded to iPhone 3G.
The question is whether I can use the original iPhone indefinitely.
People at Apple store was telling me I can use the original iPhone (without the phone functionality) as long as I don't restore the firmware.
Is this true? What happens if Apple releases firmware in the future? Would this mean that I can only use this as long as machine doesn't require restore? I wanted to give it to one of my family members so she can use it as iPod so any info would be helpful ....

My understanding is the same as the Apple Store Employee.
If you try to update the software on an iphone with no service, I believe that it will be rendered useless.
It may be possible to swap the SIM card for software upgrades, etc., not sure.

Hi Everyone Im New, Got Question About Upgrading MSI GT60 0ND With SSD

Hi Everyone I'm New, Got Question About Upgrading MSI GT60 0ND With SSD.
:welcome:So As I've stated I'm new here, or at least got a new MSI notebook.
Ive got the new MSI gt60 0ND with 750GB HD and 675 Ge-Force GTX , anyways to the bottom line.
I would like to Upgrade my computer with SSD that I bought and install the win8 on it, in order to speed things up, but I have encountered a few problems..
1. there is no sticker on the back of the computer that gives information about the serial number of my windows 8...
2. lets say in some magical way I could get the serial number out, can I use it to reinstall ? because Ive heard that you cannot use this CD key anyways unless you got a special win8 installation CD key from MSI because its MSI branded windows 8.
am I screwed ? ?? ? I thought it is possible to upgrade with SSD but it seems like MSI made it very hard, I do not understand why they even putted the warranty void sticker on the expansion bay's .... WEIRD..
Please help !! Thanks in advance,
David

Yet another question about super raid - GS70

Yes, another question about Super Raid...I recently picked up the cheapest model of the GS70 on newegg which comes with 1 mSata SSD...just a mediocre one if I remember reading correctly. I'm interested in using MSI's Super Raid once my warranty is over with and have been reading a couple posts here:
1. Walk through of how to reinstall OS
--> https://forum-en.msi.com/index.php?topic=167198.msg1224063#msg1224063
2. I'll need a Super Raid card with links to get some, for about $100 each
--> https://forum-en.msi.com/index.php?topic=171722.msg1252847#msg1252847
3. I can't get Super Raid unless it originally came with it?
--> https://forum-en.msi.com/index.php?topic=171185.msg1249640#msg1249640
So what's the bottom line? Would I still be able to enable super raid in the future or am I SOL since it didn't come with it originally?
thanks!

The GT70 CAN come with an adapter that has 2 (on the older, GT70 0NX models) or 3 (on newer GT70 20X models) sockets for mSATA drives. It's an optional part, that takes place of the primary SATA drive in the notebook, and physically has a different part that connects to the motherboard. If it doesn't come with the SuperRaid adapter, then it just has support for a single 2.5" SATA drive.
The GS70 on the otherhand, has this built into the motherboard and there is no swapping it out for a normal 2.5" SATA drive. You can only use mSATA drives (on those ports). The GS70 is meant to be an ultrabook, and therefore does not have the same ability as the GT70 to house up to 2 full size 2.5" SATA drives.
That's really the main difference here. Without physically seeing a GT70 to see how the SuperRaid adapter works, it's slightly difficult to explain.
But in the end, I wouldn't worry about the SuperRaid....The GS70 should have support for Intel Raid Management Engine, in which case that's all you really need.

A basic question about upgrading iPhoto before moving to a new iMac

I just ordered a new 27" iMac for my wife who uses several iLife programs and is a big user of iPhoto. Her present iMac still uses Tiger and iLife '08. Don't ask why Tiger! I'm wondering if there is any advantage/disadvantage to upgrading iLife to '09 before we move everything to the new iMac which will come with iLife '09? I'm not sure if the iPhoto library being upgraded on the current iMac would be moved to the new iMac "easier/cleaner" than copying the "old" library then placing it into "Pictures" (and opening it with '09 in the new iMac). For some reason it sounds "easier" to upgrade Before moving the library to the new iMac. Obviously this same "theory" applies to the other iLife applications. I'd rather ask this question today than to have to ask it when there's a great big problem!
Many thanks for the suggestions.

TD certainly you're right and I sit here laughing at the fact she has iPhoto '09 on her macbook Pro and '08 on her desktop. It wasn't until Saturday night that she let me put Snow Leopard on her MBP and I've been running it on my MBP and MP since it came out. Oh well. But at this point we'll upgrade the desktop (a PPC iMac) then can copy and move the library to the new iMac without some potential for problem.

17-e110dx How to go about upgrading ram?

Hi:
Below is the link to the service manual for your notebook.
Chapter 1 page 6 provides the memory upgrade info.
http://h10032.www1.hp.com/ctg/Manual/c04069163.pdf
Make sure you get PC3L-12800 (DD3L-1600) memory modules. The L stands for low voltage.

Question About Adding Ram from other laptop to T-series Thinkpad

Hi,
I have a question about adding additional RAM. Right now I have a 4gb ram stick in the t510. I have an acer laptop which I do not need and there is a 4GB ram stick onboard (maybe two 2gb ram sticks) there in that older laptop. Would it be possible to add one stick of 2gb ram (or 4gb i need to check if it is 2 or 1) from the acer to the lenovo thinkpad making the total ram in the thinkpad over 4gb????
Thanks in advance

Hi Richk,
Yes, I am using a 64-bit operating system. I am running on windows 7. And as for reported incompatibilities....technically taking a RAM from another laptop and placing it in the laptop should be the same as purchasing a RAM card from ebay or something and putting into the laptop right?

Questions about TDM mode on an iMac

Hi!
I'm thinking about buying 2009-2010 27" iMac, it should replace my home server, display and audio system.
Primarily, I will use it in TDM mode, and have some questions about it.
Firstly, what about sound? iMac receives it over Mini DP, right? And if I'll connect HDMI device to iMac (PS3, looking forward to Xbox One, and MacBook Air over hdmi adapter), sound will be played over desktop's speakers, as it should?
Second, and most interesting part: if connection scheme is MacBook Air->Mini DP to HDMI adapter->HDMI cable->HDMI splitter->HDMI to Mini DP cable->iMac in TDM, everything will work fine?
Also interested about cables. For example, this cable http://dx.com/p/cy-dp-021-mini-displayport-to-hdmi-audio-extender-cable-white-1- 8m-177527 supports up to 1920x1200, but basically, both DP 1.2 and HDMI 1.3b supports 2560x1600. Should I look for another cable or this one will support 2560x1440 resolution?)

Beta software is always a risk. Some beta releases are close to finished status and quite polished and bug-free, while others have significant and often crippling bugs. Not that software in official release may not also have problems, but the entire point of beta releases is to identify bugs prior to an official release, so bugs are much more likely. Sometimes you won't encounter any problems, but other beta software may take your machine down completely; it all depends on what the software is intended to do, how skilled the programmers are, and where in the beta cycle the software may be. A "public preview" release from a major developer such as Microsoft, Apple, or Mozilla is less likely to have major problems, but it's no guarantee.
It's always wise to be very cautious about using any beta software, and to take extra precautions, particularly making backups much more often and preferably not using your main computer, when running any beta software. I would recommend never, repeat never, running beta software on any computer on which you depend on a daily basis for work or critical schoolwork. If you must, make a clone of your entire hard drive to another volume before installing any beta, so you can recover your system in case of major problems.

Upgrading RAM for an iMAC Intel Core i5 2.8 GHz Quad Core - Late 2012 (I'm guessing).

I have an iMAC Intel Core i5 2.8 GHz Quad Core - Late 2012 (I'm guessing). I am trying to upgrade the RAM of my iMAC and I am not sure how to go about it. Running on OSx 10.6.3
This iMac has 4 slots - Currently my RAM is using 2 slots with 4 GB so I have 8 GB right now.
The speed is 1333MHz. Now I have some RAM that could get to 32GB but the 4 RAM chips speed is
1866 MHz.
Would it be possible to swap my old RAM (8GB) 1333MHz for the new 1866mhz RAM? even with the difference in speed? The RAM is from Crucial.
If possible I can try and swap the RAM if I get inside my iMAC.

If you are really running 10.6.3, then you do not have a 2012 machine. Please check to see if this is yours (it's a 2010):
http://www.everymac.com/systems/apple/imac/specs/imac-core-i5-2.8-27-inch-alumin um-mid-2010-specs.html
It also mentions the exact specs of the RAM. I would only use the RAM supported by Apple; using the higher speed rated RAM will not result in higher speed.

Problems upgrading RAM in G3 iMac 400

Hi there,
I'm having some problems with upgrading the RAM in my iMac G3 (slot-loading 400Mhz). It is currently running OS X Server (10.3.9 - I upgraded the firmware via OS 9). Unfortunately it only has a meagre 192 mb of RAM in so I wanted to do an upgrade. I read on the Crucial website that the machine will handle 1gb of SDRAM so I went down to my local store and bought 1gb of RAM that I expected would be compatible. The Spec of the RAM was 2 sticks of 512MB 133MHz Non Parity SDRAM 168pin DIMM (website link for RAM bought is: http://www.savastore.com/productinfo/product.aspx?catalogname=Savastore&productid=10005879&pid=44&rstrat=0) Unfortunately when I put both these sticks of RAM in, my system beeps twice and the standby light flashes slowly. I took one of the RAM sticks out and put back in the 128 stick that had originally been in there and the machine powered up...but didn't show the additional 512 stick present. Does anyone have any experiences like this? Do I have to use a specific 'Apple' branded RAM here? Is there anything glaringly incompatible about the spec of the RAM used?
Thanks in advance for your help,
Martin BG
Life as an Apple Switcher - http://aurora7795.blogspot.com

Martin,
The iMac G3 400 requires PC100 RAM. Now Crucial will sell you PC133 because they know that their RAM is of a sufficiently good quality to downspeed to work in a PC100 system. However I suspect that the cheaper RAM you've bought can't handle that downspeed properly.
In addition Macs and OS X are notoriously fickle about the quality of RAM so it's always worth spending the extra £5-10 on RAM from a Mac friendly supplier.
My iMac G3 400 works just fine with 1Gb of Crucial PC133 RAM.
For your information 2 beeps refers to "incompatible RAM installed" this article refers (link).

Upgrading RAM on my IMac

Hi I just wanted to ask what is the maximum amount of RAM that the 2011 iMac can withstand? I was thinking of buying 2 of 8GB RAM DDR3 1333, and taking out the 2GB RAM DDR3 1333 allowing me if i wanted to upgrade another 2 of 8gb rams in the future, simply because I use many heavy applications on my iMac and will be planning to in the near future simply because I use it as a workstation for my music production, I currently use Logic and Native instruments and I am planning on getting Pro tools, and Pro tools takes a lot of processing up. and other fancy stuff such as Final cut etc.
what would your recommendations be?

32 GBs is the maximum. Just leave the original RAM in as it will still work and give you 20 GBs.
