I just received two of these to put into my 20" alu iMac upgrading it from 1gb to 4gb to coincide with an upgrade to snow leopard. WOW! what a difference it has made, really fast loading times of applications, photoshop CS3 is so much faster and even surfing the net is quicker. Can't recommend enough. Don't buy the official Apple items, get these and save yourself a fortune :-)
As been stated before this is not just for macs as i have just installed in with in 2 minutes on my year old laptop and it is reporting that i have 3gb installed (i already had a 1gb stick in). The price is great for a good manufacture and you can not go wrong with the warrenty
As for people saying that it only recognizes 3gb instead of 4gb on vista 32bit this is not entily true. Your laptop will still recognizes and use all 4gb but Vista will only report that you have around 3gb, this is problem microsoft plan to resolve with vista sp1. You will need a 64bit OS if you want anymore than 4gb
What can i say about it? It's very cheap on here, especially for the brand and size, on Crucial you would pay £32.89 (without P&P) saving you around a fiver
I received the RAM well wrapped, maybe a little to much used - a bit of a waste, but all is good!
I bought one of these to add to my iMac 20", making it 3GB with the 1GB already installed. It was recognized instantly by Mac OS X, and made everything a whole lots faster :)
Ordered two of these for use in a HP NC4400 & Acer Aspire 5051, both work a treat first time. Doddle to install just a couple of screws on each Laptop covering the memory. Removed the 512MB Chip and added the 2GB. Now have 3GB in each machine and running like a dream on XP Pro.
Thx Play.com even got free next day delivery once dispatched. Ordered over the weekend delivered Tuesday Morning.
