On my AMD system, I can only get them to run 1600 MHz 8-8-8-24.
To get them to run at this speed I had to set them manually.
The original product desription said that they were made for Intel systems, so I'm not surprised they top out at 8.
I love the memory, it is reliable, it runs cool, and it looks even better.
For the price, I would not buy any other RAM 1600 MHz.
