I bought an iMac last month with 4gigs of RAM. I wanted to increase the RAM so I looked over and stumbled on this one. Ordered 2 of these. Thanks to Flipkart's super fast service, I got it within 36 hours even though I live in Gujarat and product was shipped from Bangalore.
These RAMs are high quality. It took me less than 5 minutes to install them on my iMac and voila, I am now running a 12GB monster. I can actually feel the speed. I have like 20 tabs running in Firefox, Photoshop running in full swing, songs playing continuously and a local server that runs almost 24/7 and these RAMs are taking up all the load like a boss!!!
