Kingston: sometimes good, sometimes bad.

Maybe just a coincidence, but for me at least one module was not detected correctly. BIOS update, exchange modules to each other, and so did not bring anything. Immediately to the older model (blue HyperX) exchanged, and these were immediately recognized and run as far as clean. Not everything that is new is equal better, and these variations in quality are at Kingston nothing new.
Congratulations to Amazon, since the whole exchange was very fast and hassle free!
