Hi
I have the same problem. I install more two memory (equal memory 2666mhz) but the frequency drop down for 2400Mhz. Why and I can resolve?
Be sure to use matching Dell OEM memory sticks, not retail unmatching memory.

Did you ever get this resolved?
If so what was the outcome. Currently experiencing the same issue.
Thank you!!
