Its not about good or bad, although Corsair is a top notch company.
I didn't see that kit on the compatibility list... That does not mean it wont work, just that we have not tested it. Do you have access to another kit, or even single stick, just to test with?
Edit: I don't ever recommend buying new stuff just for troubleshooting, although sometimes it comes down to that. Lets see if we can confirm that's the problem before you spend any $
