How to Unlock the NVMe Performance on the Lenovo Y700

In previous blog posts about the Lenovo Y700 where we added a high performance NVMe SSD in my case a Samsung 950 pro, others have since added Samsung 960 evo's and pro's. The draw back was that performance was capped at ~1600MB/s which leaves a fair amount of performance unavailable on these high performance SSD's. The issue was tracked down the DMI link speed being set to PCIe 2.0 speeds, this was what was causing the performance cap or around 1600MB. 

After Lenovo refused to change the setting, their is finally a work around to set the DMI link to full speed (PCIe 3.0) this fully unlocks the performance for these SSD's. Thanks to our friends over at MDL.
