My needs:

I bought this memory module for my Sony lappie a couple of months ago. The laptop was pretty old, and I was considering replacing it completely until I read about this customised new laptop RAM from Kingston. Saw it on a couple of tech blogs. Thought I'd check it out. The price looked good and it would save me the trouble of purchasing a new laptop. I picked this up from Flipkart, and I have zero complaints so far.

I thought my 2 year old SONY vaio( (E Series, VPCEH18FG with 4GB RAM) was getting slower and I decided to upgrade to 8GB RAM. I bought this Kingston 4GB RAM which fitted nicely into the 2nd RAM slot. Now I have my laptop upgraded to 8GB RAM and I can readily see a great performance improvement. I highly recommend this product!
