Thanks, and I did look into OWC, but figured why pay when my IT guy at work hooked me up with new RAM already.

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.

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.

Where is the cheapest place to buy 8gb ram upgrade for my early 2009 iMac?

Where is the cheapest place to buy 8gb ram upgrade for my early 2009 iMac, I have bought before but current upgrade is causing mac to crash randomly!? Need to know a place I can buy Ram which is confirmed to work my my mac model, the current upgrade is working but Mac is very unstable.

I meant more reasonable priced than apple
That'll be almost anywhere else then!
Yes, if it is made by Crucial and confirmed as suitable for your model of mac you will be fine. You can also buy direct from Crucial:

Ram upgrade for mac Book Pro mid 2009

Hi, I just bought 2x Kingston 4GB ram upgrades for mid-2009 MacBook Pro. First I don't notice any difference in speed. Second, the computer (in about this mac, activity monitor) doesn't seem to acknowledge it now has 8gb of ram not 4gb. Why would these be so?

You should be able to install 8GB I would check to make sure it has a secure connection. Maybe one of the RAM sticks is bad, or the port itself is bad.
13-Inch Mid 2009: http://support.apple.com/kb/sp541
15-Inch Mid 2009: http://support.apple.com/kb/sp544
They both state that they can support up to 8GB of RAM.

Processor Upgrade for iMac G3

Hello, I didn't see any particular posts specifically pertaining to the slot loading iMac (Graphite)..I hope someone can help me out.
I have a G3 Graphite iMac, upgraded RAM currently running Tiger. I used to use it but wiped it clean, re-installied the OS and created a separate account for my 8y/o son, so essentially there aren't many apps on there. For some reason it's running slower than it should, even with just Safari open. Is there a fix or possibly a processor upgrade for this model (I keep seeing that there isn't, but I want to be sure).
It's either that or constantly hearing my son complain of the lagtime and ask for our laptops instead...

According to Mactracker at one point there was a 700 MHz model available in Graphite & Snow. If you could find a 700 MHz G3 CRT iMac logic board on eBay it might be possible to upgrade the processor speed. You could also install a Matshita SR-8184 or SR-8186 DVD-ROM drive.
There's firmware available for both drives that allow them to be flashed to RPC1 or region free meaning they can play DVDs from any region in the world. Normally the drive is restricted to being able to only play Region 3 DVDs from the US. If you order a Matshita SR-8184CD optical drive from www.welovemacs.com call their 800 number listed on their website & be sure to ask for Jessica or Faith since some of the optical drives they sell don't have RPC1 firmware available for them.

Hard Drive and RAM upgrades for latest 15" MBP

I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
I like this Hard Drive...
http://www.compu2000.com/index.php?l=product_detail&p=6433
And this RAM upgrade...
http://www.a-power.com/product-10937-311-4
If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
So, does my plan hold water?

You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
Again, you're on your own for support once you do this, so weigh that in your decision.

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.

802.11n upgrades for iMac & MacBook

For any who have been waiting for upgrades for older intel machines Quickertek has new user installable 802.11n cards for iMacs & MacBooks.
http://www.quickertek.com/80211N_upgrade.php
2 GHz Power PC iMac G5 Mac OS X (10.4.9)

This has been said many times, but I'll say it again: Unless you're having them do the installation, the QuickerTek cards are a rip-off. You can save $100 by buying a Mac Pro Airport Extreme Upgrade card for $49. It's the same card that QuickerTek is selling for their MacBook, MacBook Pro, and iMac upgrades, which means they're getting about a 200% markup.

Happy to report (Ram upgrade for Mac mini))

Hello All,
I would like to share this info with you, just in case someone wanted to add more Ram to their Mac mini.
I purchased 2X4GB Kingston DDR3 Ram and followed instructions that I found on YouTube and other sources to replac my 2GB Mac mini.
The Kingston ram is very cheap KVR1066D3S7/4G but you should evaluate how much Ram you will need.
If I knew that I will only need 4GB then I would have saved my money in a warmer place (my pocket).
Anyway here is the info of my Mac mini after the RAM upgrade:
Hardware Overview:
Model Name:          Mac mini
Model Identifier:          Macmini3,1
Processor Name:          Intel Core 2 Duo
Processor Speed:          2 GHz
Number Of Processors:          1
Total Number Of Cores:          2
L2 Cache:          3 MB
Memory:          8 GB
Bus Speed:          1.07 GHz
Boot ROM Version:          MM31.0081.B06
SMC Version (system):          1.35f0

I'm not sure what your point is here. How does one actually "evaluate" how much RAM you think you need?         I think most would agree that a RAM upgrade is one of the best performance boosters for the money and the simple rule is the more RAM the better. I have a new Mac Mini with 2.3 GHz i5 processors and upgraded to 8GB of RAM from Crucial.com (complete with instructions so you don't have to search YouTube) and noticed an immediate performance increase when working with multiple applications and while playing iTunes, etc. The Crucial upgrade was only $59.99 for 8GB kit and I think the 4GB kit was only $20 cheaper so it doesn't make sense to not get thte 8GB kit.

Maximum RAM upgrade for Mac Mini mid-2010?

Hi,
I have a Mac Mini mid-2010 (Model 4.1). I purchased it with 4 Gb RAM, and I am now considering a RAM upgrade.
I currently am running OS 10.95 - and not particularly happy with the sluggish performance that has been the hallmark of my 'upgrade' to Mavericks on this machine. I figure that increasing RAM can only help what has become a sometimes teeth-gnashingly slow computer.
In any case, the Apple tech specs document says that the maximum RAM for this machine is 8 Gb. However, the macmemory.com web page for this model Mac Mini says it can handle 16 Gb so long as the OS is 10.7 or greater.
Is this true? Anyone tried this?
Thanks,
HJ

RAM upgrade for MBP 2.2 GHz Intel Core 2 Duo

I have a MBP 2.2 GHz Intel Core 2 Duo currently with 2 GB of RAM and with all the work I do on it I would like to upgrade to 4 GB. Purchasing the RAM through Apple is out of the question because it so expensive.
I would like to know what is the best brand to buy and on what website.. Is an upgrade to 4 GB possible for my MBP? It looks like I have my "Bank 0/DIMM0" filled with 1 GB DDR2 SDRAM 667 MHz and my "Bank 1/DIMM1" filled with the same thing. Does this mean that both of my RAM slots are full AND if I want to upgrade my RAM I'll have to purchase 2 sets of 2 GB RAM? Please help as I am new to all of the tech stuff...
Another side note... I've noticed that some discussions have stated that some MBP are only upgradable to 3 GB of RAM, but I'm pretty sure that I can upgrade mine to 4 GB of RAM. Can anyone shed any light on this?
Your help is much appreciated...

yes, both of your RAM slots are full, so to get 4GB you will have to get 2 2GB sticks. Having the same model I can safely assure you that it will recognize all 4GB of the new Ram.
as for brands, there have been many I have seen recommended on this board, but one name seems to pop up consistently is Kensington, I picked up my ram from the store I bought my laptop at, so I couldn't recommend a site, sorry

Ram upgrade for 2010 15" MBP

8GB Ram Upgrade for 27" iMac (Not Quad Core)

Hey guys, I have an iMac 27", not the quad core though. I want to know, what is the best UK retailer to buy 8GB of Ram for my iMac. I have 4GB at the moment, and I want to run FCP, and After Effects more efficiently, speed up Render time etc.
Where can I buy some from a shop that could be found in the Trafford Centre, so Curries/PC World , The Apple Shop, Selfridges, etc.
Any ideas about how much it would cost?
Also how much more would 16GB of RAM be?
Is it easy to install?
Thanks guys
-Bob
