^^There's no guarantee what the corsair will do. It all depends on what chips are there on it. Kingston and Corsair use the cheapest available ICs on their memory so its a hit or miss as to what you'll get. My advice, get Twinmos instead. Cheaper and you are guaranteed those MTec chips which do pretty well. LOL you were saying they are CL3, the Twinmos CL2.5 chips CANNOT DO CL3. However the CL3 chips are a different animal and crappy elpida ones.
