+1 as well. Almost a year and no official response from Dell.

May be their profits are to high - no need to communicate with ordinary customers... 

+1 ... please Dell respond

Has anybody experienced Nvme pcie on Dell XPS 13 9343?

Windows 10 is supposed to have drivers for this protocol.

I just got a XPS 13 9350 with the 256GB Samsung PM951 NVME SSD.  Not sure if it is doing PCIe 2.0 x4 or PCIe 3.0 x2, but I am getting the expected speeds:

Of course. Dell is probably never going to enable 2.0 x4 operation on the 9343, and instead is just going to expect everyone to upgrade to the 9350 if they want faster SSD speeds.

Please can a Dell representative comment in this thread if PCIe 2.0 x4 will ever be enabled for SSDs on the XPS 13 9343? The hardware is capable, and all we need is a BIOS update.

There are enough pins wired up in the M.2 slot for x4 (as required by the M.2 standard; there are no M.2 slots in existence wired only for 2.0 x2, only 2.0 x4 and 3.0 x4) and the Broadwell PCH chipset supports enough PCIe lanes (2.0 x16 total; x2 of which is used by the WiFi+Bluetooth card, and x2 for the SSD). The reason it's limited to x2 lane width is solely due to "power saving" mode code in the BIOS that can't be disabled except by a BIOS update.

I am asking for Dell to allow us to disable this mode in the BIOS.

The sm951 NVMe can be seen by Windows 10 on the 9343, but the Computer is not able to boot from the device.

@Dell: Will there be a boot support for SM951 NVMe in future BIOS?

Any update on this?

Thanks for your information first.

Recently, I desire to upgrade my stock SSD to SM951, but the recognizing problem put me in deep consideration.

My 9343 is running BIOS version of A07. Does it compatible with the SM951 512GB?

Your precious information will mean the world to me.

Thank you.

Hey there, any news with the A07 BIOS?
