I put two copies of the memory card on a DELL Inspiron dated end of 2012 totaling a total of 8 GB of RAM. They operate at a frequency of 1600 MHz.
The bar is known from the start, I see a glaring difference from before (I had 2 strips 2GB 1333 MHz), especially at the start of Windows 7 (Home Premium Edition 7) and the opening of the majority of the most used applications (Photoshop, Word, Excel, Chrome, Firefox, Evernote).
At the games is also more comfortable and responsive (it has less lag choosing the details of "good"). Too bad I could not test on recent games (my graphics card is quite limited).
Nothing to say about this bar is that quality (as all Kingston memory cards that I tested). It boosts the overall performance at an attractive price and allowed me to put off buying a new laptop.
