A:AnswerNo. That device uses DDR3. This memory is DDR4. I could not find any information on it that system had a refresh change to include DDR4 memory compatible motherboards. I highly suggest not purchasing this memory as it most definitely will not work.
A:AnswerHello Shell,
I'm only seeing 2400, 2666, or 3200 being recommended for that system. Please confirm with your manual, and do reach out with any other questions: support.corsair.com
