Dell M.2 / NVME Specifications And Upgrade Requirements For Latitude, XPS, Precision Mobile and Optiplex

@Tuchivi,

I will try to find out the number of lanes on Vostro 5468 and get back with you.

As for the detection problem it's probably not a matter of lanes. When you say the drive isn't detected, where exactly are you discovering that? Is it during an operating system install? Or have you gone into the BIOS and found that the drive is not listed there?

If the drive is listed in the BIOS then you need to make sure you're using the Samsung driver for proper drive detection and performance. That driver is found here: www.samsung.com/.../Samsung_NVMExpress_Driver_rev11.zip

If you need help regarding how to install this driver reply back and I'll see what I can do.

@Tuchivi,

I heard back from a source who advised that the M.2 port on the Vostro 5468 is wired as SATA M.2, not PCIE M.2. So you actually could have an issue with drive type, like you had assumed before. I don't know if the Samsung NVME drive is backwards compatible with SATA M.2 ports. You'll have to contact the manufacturer to find out.

Interesting...  how about the M.2 port on a Precision 3620 tower?

I plugged a Samsung 850Pro 1TB NVMe drive into one and the 3620 doesn't see it, even in the BIOS settings.

@Justin C,

I have a Dell E7470 with default M.2 Lite-on module. I try to upgrade it to Plextor M8PeGN for the last 4 months, but I can't get it working. First I was thinking the module was the issue. The bios reconise the module. In the Windows 10 Pro setup I see the Module and can install Windows without any issues. Only after first boot the boot partition is not find.

After try a new install from Windows I see the old partitions and see also the data. Only it issn't possible the format a partition or delete them. After this I can't do anything anymore.

I use the latest bios, try latest sata drivers in windows setup. For the rest no idear anymore.

I understand from Plextor that the module is compatible with E7470, but is this correct?

Anybody else with the same issues? I can't find anybody with Plextor Module and E7470.

Another question is the Samsung 960 Pro working with the E7470?

Hi Darr.Darr,

The Precision 3620 comes with a PCIE 4X slot.

I can't say why the Samsung 850Pro 1TB NVMe isn't detecting but I think you're probably seeing a compatibility issue.

I can only offer support for drives we sell with systems. For example: Part number W53CK - 1TB PCIe PM951 for Precision 3620.

@Justin C Thank you very much for the info you offered.

Until this Morning, I knew from your info, E5470  with I7-6820HQ' s slot M2.0 supports PICE 3.0X2 only. But E5570 supports X4 while H CPU. Can I ask you if Dell's team could issue a new E5470 BIOS to support the same as E5570?  

Thanks for your help in advance and Best Regards

HI! Justin C

Thank you very much for your infos.

Can I know if Dell's support Team could issue a new Bios for E5470 with H CPU supporting M2.0 to PICE 3.0X4? In General, E5570 is similar to E5470 while the offical M 2.0 configration is not.

Thanks for your kind help in advance.

Best Regards

Justin C,

Yes, my 3620 has an empty 4-wide PCIE slot, as well as an empty x16 PCIE slot (the main x16 PCIE slot being occupied by an nvidia quadro K620), and even a legacy PCI slot. It also had an empty M.2 slot... I even see an empty header on the motherboard for a (non-existent) second M.2 slot...

Anyway, I procured a 512GB samsung PM951 (actual capacity 476.8GB), and after swapping out the 1TB samsung 850 the PM951 does indeed show up in the BIOS just fine.

Thanks.

any update for the latitude 7370?

just wonderin if i can put 2nd ssd on the wwan mpcie slot?

Thanks

My screen suddenly went black. But my laptop is working fine.

I restarted several times, still no solution.

If your system is running and screen is black or blank.

Just wipe your RAM and you could able get the screen back.

Its all about the ram usage.

Thanks for the solution.

Hi

Can you post information about the M.2 support of Inspiron 7460?

Regards

Did you find out anything on the 950 pro? I put one in my XPS 15 9550 with no problems. I've ordered one for my latitude e7470 bUT now I'm seeing something where ithe can't run the nmve to its full potential. Basically only x2 instead of x4. Then I've also read that there is a way to get it to run x4....so I've been looking EVERYWHERE to find some answers.  Any luck?

> Did you find out anything on the 950 pro?

I returned mine to amazon, since the answer I received here indicated Dell might not support them. From info I've found elsewhere, its full speed potential requires the Intel Rapid Storage Technology driver... and it's my understanding that driver doesn't load if you set the SATA controller (in BIOS) to use AHCI instead of the (typically default, if installed) hardware RAID.  Is that driver offered in your XPS's Drivers and Downloads page, and do you have RAID enabled?

You mention the XPS 13 9350 is x4 capable in the M.2 slot.  

The specifications manual shows the PCIe data rate as 8 Gbps.

Are the two statements compatible?  Is the M.2 PCIe drive limited for some other reason other a PCIe lane limitation?

There are many ways to look at numbers, but what I see is x4 with PCIe 2.0 is 16 Gbps and PCIe 3.0 is 32 Gbps.  When I see a speed rating where a SATA drive is 6 Gbps and a PCIe drive is only 8 Gbps, I am a little disappointed.

Thanks... just trying to decide if I need to go with a PCIe drive rather than SATA.
