Product: Envy X360
Operating System: Microsoft Windows 10 (64-bit)

I am upgrading my M.2 SSD to a 512 GB Samsung 970 EVO Plus and don't see the option to change from sata mode to pci-e mode to take advantage of the greater speed. Anyone have any solutions? I am working on a HP ENVY x360 Convertible 

15M-cp0012dx with the Ryzen 7.

That is not something you need to do in the BIOS. The system either is designed to work with an NVME/PCIe M.2 disk or it is not. The specs for your model say the existing M.2 delivered from the factory is NVME/PCIe so you can upgrade it to a larger capacity Samsung Evo 970 without issues or needing to adjust the BIOS.

I guess I will find out Staurday when I switch them out. Currently the bios says the drive is running in sata mode.

I do not have a BIOS simulator for that model but I have not seen a "mode" setting in the BIOS for M.2 SSDs. Can you confirm the model of the SSD from device manager which will tell us for sure that you have an NVME M.2? Maybe a screen shot of the BIOS setting you are talking about?

The current M.2 drive installed is a Toshiba KBG30ZMV256G. Not sure how to screen shot from the bios.

That is an NVME M.2 and I suggest you run Crystal DiskMark (free download) on it. If it were in SATA mode transfer speed would be about 550 Mbps and as NVME you should get something over 2000 Mbps. Anyway if the Toshiba works and is recognized the Samsung 970 Evo also will work and be recognized and then the only issue is whether its performing as it should. I have seen some complaints that Ryzen systems seem to be locked into an x2 PCIe mode instead of x4 but that would mean your disk read speed would be more like 1200 or so rather than closer to 3000 in x4 mode.

According to the OCZ/Toshiba SSD Utility the sequential read/write is 923/779, and the random read/write is 286/155. I hope the system is not limited to pci-e x2, but it seems that way.

I agree. If you google around you will find a few instances of this. I believe an updated AMD chipset driver might fix it but I have never actually had a Ryzen system.

Just finished installing my 970 Evo Plus, and indeed I am limited to x2 pcie. Still a great improvement over the original Toshiba drive. Now I am getting 1782/1654 sequential read/write.
