Question: Is it compatible with my iMac
Document: My System:iMAC Mid 20072.4GHz IntelModel MA877LL - 20 inch 320GB HDWorks great with my iMAC... I was concerned about it being compatible, so I went to Crucial.com and talked to live customer support and confirmed it would work for my specific system.Pros: Noticeable performance with the 4GB from the previous 2GB I had. Opens software, loads pictures and any information at an instant! before I would wait seconds to load. The "stuttering" or "Pauses" between applications is gone.
Easily installed some months ago, they've performed as advertised with no issues. We would certainly recommend them for others with compatible notebooks.
Compatible with my Macbook 4,1. No problems, but in Windows 7 32-bit, only 3.2gb are recognized. This is a limitation in 32-bit operating systems, not the RAM.
*Which is the max that the 32 bit OS the Dell was running could recognize, so it was a success. *The increase in speed was quickly apparent as there were programs on the computer that were struggling to run prior to the upgrade that ran with ease afterwards. So if your looking to increase the memory in a Dell Inspiron 1721, these are definitely compatible.
Recently was in need of increasing the RAM in someones Dell Inspiron 1721. While the Crucial site does say that the PC2-6400 version of this same sick is compatible after the Bios has been updated and flashed, we discovered that only 1 out of 2 PC2-6400 could be loaded. The computer just didn't have enough juice to run 2 sicks of the 6400 (it did with only one, we tested).
The RAM was perfectly compatible with my mid-2008 MacBookPro. One piece of advice- you need a Philips Size #00 screwdriver to open the door on the RAM compartment of the MacBookPro. I had to search all over town and eventually bought one at a small electronic supply store. Do yourself a favor and just order one at the same time if you plan to put this RAM in your MacBookPro.
Selecting the correct (compatible) RAM can be a daunting task. Crucial make it easy with their system scanner. Just go to the crucial site, let it scan your system, pick the option you want, cut and paste the description into Amazon and you're done. Crucial also has video tutorials showing exactly how to upgrade/swap and you can't beat a lifetime warranty!
I was in a panic on Monday because I'm a Medical Transcriptionist and one of my clients updated their software rendering my computer obsolete! I use a MacBook that I bought in 2007. It has a dual core Intel processor and I set up a virtual PC because most medical facilities aren't compatible with Mac software. Bottom line...I needed more RAM! When I started to research this, it seemed like my MacBook was maxed out with 2 gb of RAM.
I ordered this pack of memory for my MacBook. It worked like a charm. Works as advertised just like it should. I felt the need to tell everyone that I purchased "Mac Compatible" memory from Best Buy and one 1 of 2 sticks would recognize. I exchanged it for another pack thinking that it was just a bad batch that I got ahold of. Same thing happened again. After reading some reviews and seeing th Crucial guarantee I purchased this and am satisfied. Don't make the mistake that I did.
Beefed up my iMac with no effort at all.
Answer: I bought it to upgrade my iMac approximately 2007 year model.  I believe the packaging says for laptop but my iMac needed this type/size.  I successfully installed it myself, easy to do.  It does depend on your model.  The link already shared looks like the place I used to get information to decide if it would work for mine, http://support.apple.com/kb/HT3011.  Hope this helps!
