Mikhailtech has posted a Crucial 512mb PC2100 SODIMM review

So I decided it was time for the final upgrade. With a maximum capacity of 1024mb, I was going to turn my Dell into a real monster. This time Crucial decided to help out by sending over one of their 512mb SODIMMs, the largest capacity currently available for notebooks. Reason being?
