Thalmes:

I m using Corsair DDR3 1066, 2 pcs 2GB rams on my MBP 13" 2.26mHz SnowLeopard.
Been using since last 3 weeks. Nil problem to any applications. Running all 3 editing programmes....CS4 , Picasa and Lightroom simultaneously...." not really fast and not too slow BUT not hang "...thus satisfy me. Compare to only 2GB running alone, it was too slow ( slow action responding ) when 3 programmes running together.

Price that time I bought : RM 165 for 1 piece 2GB
