[NAME] I don't think you mean Intel Speedstep chip but I think you mean that you have Intel Optane memory. Intel Speedstep is not a chip by a system feature that dynamically adjusts the voltage and the core frequency.of the CPU. Intel Optane memory acts as a cache to speed up the hard disk drive. First, you need to disable the Optane memory from caching the HDD. Next, you need to remove the Optane memory and install the SSD. Then you can clone the HDD to the SSD, disconnect the HDD and boot from the SSD. Assuming you are unsuccessful, then you can run the procedure to change SATA operation from RAID to AHCI on the SSD. I prefer running the procedure to change RAID to AHCI on the SSD last instead of running the procedure on the HDD before cloning in order to preserve the HDD in case there is a problem with the procedure. 
I have a new WD BLUE SN550 NVME SSD (1TB) and I want to swap out the Intel Speedstep chip on my XPS8930,, then reinstall WIndows with the Dell OS Recovery on USB.  Will this work?  A little information.  I have tried and (repeatedly) failed to implement the instructions for setting RAID to AHCI. The best I can get after following instructions in these forums is a bootloop with Dell Recovery options. I have work to do so I just go back to RAID so I can work.  Thank you for your time. Robert  
Can I install a WDSN550 SSD NVMe drive in my XPS8930, and reinstall WIn10 with 
recovery USB?
