Additional RAM needed for iMac G4 1.25 GHz

My iMac currently has 256 DDR SDRAM installed. I can't install Adobe Creative Suite as it needs 384 RAM.
My question, do I have to match the 256 in the empty slot on my machine, or can I get more RAM?
I assume also that I have another slot for more memory.
Thanks

Undo four screws and you get to the User Slot. Undo a further 4 screws and you get to the Factory slot. It's not nearly as friendly to get to the factory slot but still very do-able. The iMac G4 20" takes up to 2Gb so you could put a 1Gb DIMM PC2700 184pin in the factory slot and 1Gb SODIMM PC2700 200pin in the User slot.If you open the case you must replace the thermal paste when you clsoe it up to prevent overheating.
Here are the instructions.
I fold a blanket and put it on a table then place the screen carefully on that and then use a foam keyboard wrist rest to brace the dome whilst I undo screws.

How much RAM needed for the DB box

Hi,
Can someone share with me the technical way to do calculation of how much of RAM needed for a new Linux box with estimation of 500 users. I hope this calculation can also allow me to breakdown how much MEMORY needed for each session.
Please recommend any site that I can refer to if any. TQ.

My project start with Oracle 9i R2 (9206) on Linux (not yet confirm on the platform and etc). Just assume I will use Linux Red Hat Adv Sever latest version.
Hence how many GB of memory for the box is sufficient to handle 500 connections. Pls guide me the formula to derive the calculation. TQ

There are some highly experienced people here running Sophos free who say it's just fine. A lot of this talk here is urban mythology.
I'm not sure I qualify as highly experienced but I've run Sophos Home Edition almost since the day it was released on multiple Macs & I have had zero problems with it. I've even tried to duplicate the few reports of specific issues with it as best I can, but unfortunately almost none of the reports are from direct, firsthand experience. When I ask for details, I get evasive or incomplete answers, making it impossible for me to do much in that respect.
One thing I've noticed about many of those denouncing any & all commercial Mac AV software is a tendency to blame it for any problem they see without doing much if anything to try to verify that assumption. Another is that many of these folks don't seem to know much about how these apps can or should be configured, or how that can affect their operation.
But most of all, it seems to be an article of near religious faith for some Mac users that this kind of software is completely & absolutely unnecessary, downright evil, always a scam, etc. & react to any comment about that being overly simplistic as if it was heresy.
Please make no mistake: I'm not trying to tell anybody if they should run AV software on their Mac. I'm just suggesting that not all AV apps should be judged as if they were the same, nor should a few scattered or vague reports of issues with any particular app be considered as meaning it has or deserves a bad reputation. (If that were true, you could say the same of almost any app, to say nothing of every version of OS X or update for it Apple has ever released!)
All that said, Norton & MacKeeper (not to be confused with the MacDefender malware) do not have great reputations (for different reasons) & probably should not be serious contenders for anyone considering an AV app for their Mac. ClamXav is the most often recommended one, & as MadMacs0 mentioned, you might want to consider the newest full 2.0 version (not the app store one) if you want background scanning. It is not quite the same thing as say Sophos offers in that respect, & requires somewhat more effort to set up than Sophos' 'on access' scanner, but that's the point:
One size does not fit all, so be at least a bit leery of the advice of anyone that says otherwise.

Why doesn't the new ram memory for iMac (mid 2011) work (different brand)?

Hello,
I have an Macbook pro at home (early 2011) and an iMac (mid 2011).
My macbook pro had 2 x 2GB ram and I wanted it to be higher, zo I bought 2 x 4GB ram from Kingston. I installed it succesfully in the macbook pro.
I saw that the ram in my macbook and iMac where the same type (1333MHz DDR3), so I figured the Ram-modules were interchangable. The iMac has 2 x 4GB ram put in by Apple itself. It's a weird brand name, something Asian that I hadn't heard off.
I thought I could put the original ones from my macbook pro (brand Samsung) in with the original ones that where already in the iMac.
So the slots would look like:
4GB 4GB -> already in iMac, original modules with brand name I can't remember ;-).
2GB 2GB -> original modules from macbook pro Samsung
I also put in in like shown: the same types next to eachother.
Then I turned my iMac on and it only "beeped".
So I tried to put it in different combinations (4GB next to 2GB etc etc). But it still "beeped".
Very frustrating... because I thought I was doing a good thing by buying Kingston (quite expensive also...).
Now I think I had better purchased new 2 x 4GB Samsung and combined that with the 2 x 2GB Samsung from the macbook and put it all in the iMac. And take those of the iMac (2 x 4GB Asian brand) and put those in the macbook... This way it were all the same brands combined...
But I did by Kingston... so... why can't I combine the original iMac ram modules with the Samung modules from the macbook????? I've read that in older iMac models, the slots are sensitive for different brands, but couldn't find out for sure for my iMac (mid 2011). It's a bit stupid, no... Both mac's are from 2011 and have the same specifications...
Could anyone give me an answer?
A little bit mad at Mac right now ;-).
Thanks in advance!
Wallking.
PS: if it is about the OSX I'm using... can't update to Maverick for software licence reasons... I need the iMac for work a lot...

Hello,
I'm sorry if it wasn't clear... but I don't have ram issues with the Kingston type...
I used the new Kinsgtons in my macbook and wanted to take the originals from the macbook (Samsung) and them put in my iMac next to the other modules that were already in the iMac.
I know it's a bit confusing... ;-)
So... I have 2 x 4gb in my iMac from a brand I can't remember the name off... And I also wanted to put in 2 x 2 GB Samsung modules. So that would count up to 12 GB ram. Why? Because I took the Samsung modules out of my macbook and I thought I could reuse them in my iMac since they have the same specifications (1333MHz DDR3). But My iMac won't start up as soon as I insert those 2 Samsung modules.

Cost/benefit of RAM upgrade for iMac G5 2 GHz from 1.5 to 2.0 GB

Equipment: iMac 20" 2.0 GHz, 250 GB HD, originally 500 MB RAM upgraded to 1.5 GB: (1) 500 MB and (1) 1 GB DDR SDRAM, PC3200U-30330.
Not understanding the subtleties of memory upgrades, I bought this off the shelf with 500 MB RAM. When the processor board was replaced, I added a 1 GB RAM and can't say I noticed any change in performance. It does reduce the need for page outs.
After this, I read something about needing to have the DIMMs matched for there to be a performance gain. Or maybe this related to 64 bit operation? I read elsewhere in the Discussions that 64 bit operation would actually consume more memory and reduce performance.
If I upgraded to 2.0 GB, would there be any improvement in performance? In general or only in certain situations?
If I upgrade RAM, I'll have (2) useless 500 MB DIMMs. Is there any value in these? Where is the best place to sell them or do they have value as trade-ins?
Or is the best use of the money to put towards an Intel Mac that can support 10.6+ ?(...or a share or two of Apple stock.)
Please convey your wisdom. Thanks.
P.S. I know the stock is the best use of my money, so just consider the hardware options.

I happened to find this answer while looking for something else.
iMac G5 and iMac G5 (Ambient Light Sensor): Benefit of using matching memory modules (RAM) http://support.apple.com/kb/HT2708
Condensed version:
Applies only to original iMac G5 and iMac G5 (Ambient Light Sensor).
*If it has matching DIMMS it operates with a 128-bit data path, otherwise it uses a 64-bit data path.* A 128-bit data path allows greater throughput than a 64-bit data path. This allows faster manipulation of large files. With a 128-bit bus, you would see better performance when you have multiple applications open at the same time. Also, some enhanced gaming performance.
According to this, I was getting better performance before I added the 1 GB of RAM, except that degraded performance due to stuffing RAM to the gills has to be weighed against that. Seems like trading up to a full 2 GB would have some unquantified benefits. The only ways to find out are to find another iMac to compare with or to put in the RAM and see what happens.

Additional RAM needed

Trying to load new software, both of which tell me I need 1-2 GB of RAM. Where do I determine how much RAM I have, and can I simply buy and upload additional RAM to this model?
Thanks.

Hi
+"Where do I determine how much RAM I have?"+
Apple Menu > About this Mac.
+"can I simply buy and upload additional RAM to this model?"+
Yes. You buy RAM and physically install it. Depending on the model you may be able to do this yourself with an appropriate screwdriver or pay/get an authorised Apple Technician (or someone else who is capable of doing it) to do it for you. There's no upload involved.

RAM maxi for iMac 2,4GHz Intel Core 2 Duo

thanks a lot in advance : is it a good idear to have 6 GB in RAM DDR2 SDRAM 667MHz-( 4GB + 2 GB )-
on my iMac, processor 2,4 GHz Intel Core 2 Duo ( 20-inch ) ?

This one ?

If you or your Mac really needs the 6GB RAM than sure.
The slight decrease in speed due to not using paired-RAM isn't comparable to the gain you get from the additional RAM.
Have you used Activity Monitor as described in here Mac OS X: Reading system memory usage in Activity Monitor to determine whether you need more RAM ?

What's the best quality and cheapest 1GB RAM seller for iMac Intel?

I am looking to buy a 1GB RAM chip for my iMac Intel. However, this can be very expensive when bought straight from Apple. Where else can I get 1GB of RAM for a cheap price that will give me the quality I am looking for?
iMac Intel Mac OS X (10.4.8) Currently have 512 MB RAM on iMac

Yes, you can successfully use a single 1Gb module. You can just as well add a second one that isn't matched. However, it should be very easy to match RAM modules without buying the second one from Apple. To be "matched" they must both be same speed, same size, same number of component chips on both sides.
Size is easy, both 1GB. Speed is easy, both PC2-5300 667MHz. Component chips - little black square or rectangular chips attached to one or both sides of the board. Count the number on each side of the board and duplicate that configuration and the two modules, one from Apple and one from xyz company, will be "matching" RAM. If there are 4 on the front and 4 on the back, buy another like that. If there are 8 on one side, and none on the other, buy another like that.

Is 2 gig of ram enough for a 2011 2,3 ghz mac mini for doing some games? Like GTA IV

Is the standard 2GB of ram enough for a 2011 2,3GHz Mac Mini for doing games? Like GTA IV.
Or do I even have to go for the faster 2,5GHz model?

I have a MacMini Late 2011 with 2.3 GHz I5 and 4GB RAM and I use it as media center... It's enough to play FullHD movies but it uses 256 on 512 MB of (shared)RAM... I don't think that you can use a mini for hard gaming...
But AngryBirds Space on a 60" FullHD TV looks great

RAM Memory for iMac 27' (Late 2012)

Hi,
I have read a lot of discussions about what's the best option to upgrae the RAM for the iMac 27' (Late 2012), but I really don't know what should I buy in terms of compatibility.
Kingston ? Corsair? ,etc...
I pretend to remove the memory that's on my iMac (2x4GB) and install new ones 4X8GB=32GB, so, my question is, which brand should I buy, and also what about the voltage(1.3, 1.5) and latency (CL7, CL9, CL10, CL11...)?
Thank's

If you will go to either OWC (macsales.com) or Crucial, their sites will help you determine what you need.
http://eshop.macsales.com/shop/apple/memory/iMac
Use OWC's instructions to find your model identifyer. Their RAM has been tested and is guaranteed.
I would not recommend cheap brands or Value RAM.

D/A converter needed for Imac to TV?

I want to watch my FCE timeline or canvass on a TV while editing so I can see if I have the color corrected appropriately. I do not have a camera or a deck. I import my film from an external hard drive on which I have old home movies from the 50s and 60s digitized so I can edit in FCE.
Can anyone tell me how to set up in a chain a D/A converter and a TV with my Imac? What kind of a D/A converter should I purchase?
I have looked a lot on this forum and don't really understand what I should do. I am not a professional at all. The technical language I read is almost impossible for me to understand.
Can someone tell me in layman's language what i should do. I would appreciate any help.
Imac G5 Intel Mac OS X (10.4.8) 2 500gig external LaCie Drives

A D/A converter is a box that you must connect on one side to a firewire port of your Mac (with a firewire cable) and on the other side to your TV with an analogue cable, usually with 3 different "RCA" plugs: yellow for video and red and black (or white) for audio.
After connection and a proper setup of the converter, when you play your timeline in FCE (or Print to Video) the video and audio are directed to the TV through: firewire cable -> D/A converter -> analogue cable -> TV, and you can check the final result of your editing: colors, but also possible effects of interlacing on your video, and so on.
I use my camcorder as a D/A converter (and A/D as well), and I don't need a specific box. So, while I know some converters exist at prices around couple hundred dollars, I cannot give you specific suggestions about which might be good for you.

How big a hard drive do I need for iMac and Time Machine?

Sorry if this has been answered elsewhere already. I am going to buy an iMac, probably the new 24" with a 320G internal HDD. I already have one Lacie external 320G HDD so I was wondering whether I can use this for Time Machine backups, or do I need to buy a bigger one? If so, how big? Is there a rule of thumb for working out how much hard drive space you need to have for Time Machine, for instance if I were to buy the 500G iMac what would I need?
thanks.

I agree with the "double the size" rule of thumb. You should also consider how much of the 320GB you are actually using and are likely to use in the next year or two. After all, it's the amount of storage you use that matters, not the size of the disk. Disks will very likely be cheaper soon. You should also keep in mind that TM deletes old archive data when it runs out of disk space. So as long as you have more disk space than you have data to back up, TM will work, though you will lose older versions of your data.
So if your 320GB drive only has 100GB used and you're not the kind of person who eats up disk like there's no tomorrow, the 320GB drive should be fine for now. If you expect that 320GB disk to be full soon then a 750GB TM disk is more like what you need.
The same logic applies to a 500GB iMac. If you only expect to use 250GB in the next year or two then a 500GB TM disk should be OK. A 1TB drive will be a lot cheaper next year or the year after.

What replacement wifi card do i need for iMac 21.5-inch EMC 2308 late 2009 model

Need to replace wifi card. For the life of me, I can't find the exact model # of wifi card I will need. Only that I need "AirPort Extreme (802.11g/n)," but when I search for that, I get all sorts of different shaped and sized cards that meet those specs.

I would try giving them a call at their support number. They may be able to help both identify the correct part and know where you can get a replacement. In addition, you may also want to consider getting a wireless USB adapter. You would use this instead of the internal card. There are a number of vendors providing these as well.

DVD-RAM support for iMac (late 2006)

Hello,
according to the thread:
http://discussions.apple.com/thread.jspa?messageID=4755862
I have a iMac C2D 2,16GHZ and a Pioneer DVR-K06 DVD Drive
According the pioneer specifications this drive supports DVD-RAM read and write.
( http://www.pioneerelectronics.com/vgn/images/portal/cit3424/310207082POVDVR-K06.pdf )
But it isn't possible. Why? DVD-RAM is ideal to backup data. It can be rewritten over 100,000 times (DVD±RW approx. 1,000 times)
It is possible that Apple supply a firmware update that allows to read and burn DVD-RAM?

Thank you and SG for your responses.
Several of my TV's DVD Recorder features are not available with the use of a regular DVD disc and require a DVD RAM disc (chapters, etc.) So I decided to do some experimenting and cross checking of the DVD Recorder and my computer DVD-RAM supported DVD burner/Premiere Elements with regard to disc types for DVD-VIDEO. That is what got us to my question.
Several months ago, I got involved in someone else's issue where he could not rip content from a DVD disc which had its origins in a camcorder that recorded to either a DVD-R or DVD-RAM disc. I suspect that my mini test ran into similar issues, that is, DVD-R with the recording format of DVD-VIDEO and DVD-RAM with the recording format of VR. (I added this explanation to clean up my previous misspoken comment about DVD-VIDEO format having a different folder/file structure depending on whether a DVD-R or DVD RAM was involved.)

Visit this link, I have used this memory in various mac and windows computers. If you do not wish to use this manufacture the scanner they provide will still tell you the memory you need.
