I have a mid-2008 24" iMac and ordered this memory to upgrade from 2 GB to 4 GB. It was a slick install and I was back up and running in no time.

My 2008 iMac is showing signs of age, and to get some of its zip back, I decided to upgrade the memory and operating system, in steps. I upgraded the memory first, from 2 gb to 4 gb. After looking at prices at various stores, found that Amazon has the lowest cost option, and a brand that other Mac users found to work well. So, I ordered the Crucial memory sticks, from Amazon, and was glad to save ~$10 from the next lowest alternative.
Installation was easy, and the computer boots up a lot faster now. I see an appreciable improvement in the time it takes to launch Adobe CS suite applications.

Decided to order through amazon because it was $10 cheaper than through the manufacturer. I contacted the manufacturer who verified it was the same product as Part #: CT817125. I installed it in my Imac, and it was extremely easy to install. Booted right up and faster than before.

I bought this in November of last year. It got to the point where I'll be using 60% of my 2Gigs I was previously using and notice the laptop was stating to slow down. I'm using a Dell Inspiron 1525 with Vista 32Bit that I bought in March 2008. The extra 2Gigs made a huge differences and speeding up my computer right away. Replacement is easy, unscrew the under-panel (have the laptop shut off), push down a little and the old RAM chips lifts up, pull out, push in the new chips and press back in and place the cover back in. Been almost a year and I never had a problem.

Be aware the 32Bit Operation System such as Windows Vista and Windows 7 32Bit would only use max of 3.5GB of RAM and buying something more than 4Gigs for these system won't improve your performance until upgrading the the 64Bit version.

Also when I purchased this back in November 2010, it was around $80 and see is now (as of Oct 5, 2011) it's down to $50.

I expected the performance of my 2008 iMac to improve by upgrading from 2GB to 4GB but I didn't expect such a dramatic and noticeable difference as what I experienced. Wow. Great investment. Programs launch with minimal delay (nearly instantly) now where I would get at least 2 or 3 icon bounces and significant delay before launch before the upgrade. Thinking about installing a SSD next! With just the RAM upgrade, I just added a couple of years onto the usable lifecycle of this 4 year old machine.

My Dell Latitude D630 came with 2GBs of DDR2 Ram: specifically Hynix 2x1 GB 2Rx16 PC2-5300S module which works fine most of the time. However, with avast running in the background sometimes it get bugged down when I am downloading large files such as during Metastock data updates. Following this upgrade everything now runs smoothly regardless of how many programs I am running simultaneously.

My laptop runs Windows XP Professional 32 bits. That of course means that my system only sees 3.49GBs of the 4GBs installed memory. The only way to get the laptop to see the entire installed 4GBs of ram is to upgrade to 64 bits operating system such as windows XP 64 bits or Windows 7 64 bits. Nevertheless, I am happy with the performance of my laptop as it is now.

NB: Upgrading the memory in Dell laptops can be a pain for a non-techie especially the Inspiron and Latitude series. This is because Dell engineers in their infinite wisdom decided to hide module A ram under the keyboard of all places. To get to it you must remove the keyboard. There is a youtube video posted by a user named iftibashir. The title of the post is "Upgrading RAM in a Dell Notebook". It is 8.05 minutes long and clearly shows how to do this even if you are not a geek. Hope this helps.

I purchased this RAM for my iMac Early 2008 model and it works perfectly fine. This type of RAM is $60 on the crucial website but much cheaper here and it's the same exact thing, so if you're curious if this ram will work with your iMac 2008 model, yes it will! It made my iMac much faster.

2gb of ram was fine when I was just sending email, browsing the web, recording TV, and using other iLife apps. However, I picked up some work that required adobe CS5 and realized that I needed more ram. This was very easy to install and my iMac started up as normal, but with 4gb of ram. I have noticed a big improvement in performance running photoshop, dreamweaver, and after effects all open at the same time. I have even noticed a big speed improvement in my iPhoto library. It is quick to load pictures and quick to recognize a camera when attached. If you want better performance without buying a new computer give this a try. If you are still unhappy, then at least you have bumped the specs of your machine which can help it sell.
