After waiting a bit over a week after placing my order they shipped me 2X1GB PC5300 and they have arrived. Not sure if this was mentioned before but they had not finished testing them, even though they were still for sale... couple extra notes: 1. I will let you know how it works when my macbook arrives 2. The ram chips are fairly small about 1.1''X2.4" 3. DMS raised their price from 108 bucks (what I paid ) to 115.
