XtremeComputing posted a review on the Gskill F1-4000BIU1 PC4000 2gig kit

Today we are looking at the F1-4000BIU1-1GBHV 2-gig memory kit, this kit aims to deliver 500 MHz with 3,3,2,8 timings and I believe it would, going on the current buzz in the community. I think these should be up to scratch, but with lower timings than the Corsair we recently looked at, I do not believe there is going to be much clocking.
