Kingston's modules come shipped in their traditional pack which have a black backing and clear cover so as you can see the modules inside. This package is the same one they use to ship all of their HyperX series, with the paper sticky band that seals the modules to the package. On the band you get a model number, unfortunately if you want to find out the specs of the modules you need to understand the code that Kingston uses on their packages or go to their website.
Unpacking the modules from of the box you get a slightly better view. The heat spreaders used resemble some of the older aftermarket coolers which have double-sided tape to hold onto the memory chips as well as brace clips to keep the heatsink on when the RAM chips begin to generate heat.
Lastly we come down to the sticker that Kingston places on the modules. Kingston places the info in a cryptic code, so if you don't know how to read the code you won't know much about it. The modules are rated for 1375MHz using 7-7-7-20 timings but you need to use 1.7v to run this, as these modules are designed for 1066MHz operations at 1.5v, they have just been juiced up to run up to 1.7v with 1375MHz.
