murrays 0 #1 October 2, 2007 I have 2 512mb sims that I took out of my new Macbook when I upgraded to 3gb. They are 667mhz chips. The label on the back has the following info: Nanya - appears to be the manufacturer PC2-5300S-555-12-A2.512MB.2Rx16.667 If you have a Macbook they would work in or a pc they will work in you are welcome to them for the cost of shipping. Send me a PM if interested.-- Murray "No tyranny is so irksome as petty tyranny: the officious demands of policemen, government clerks, and electromechanical gadgets." - Edward Abbey Quote Share this post Link to post Share on other sites
