Otherwise it seems pretty good, not too expensive, 1600 MHz with 7-7-7-22 timings which are pretty good, although I'm not why the seller says CL9 when he's running them at CL7. Although the memory chips aren't from a generic brand, I'm not too sure about the actually RAM itself...
cheers for the reply that is indeed good ram i have now narrowed it between 2 gskill products both with free delivery, and decided not to bother with the ebay no guarantee's.
one has timings of 7-8-7-24 £100
one has timings of 9-9-9-24 £92
