In your first post you mentioned an Inspiron 7559, and in your latest post you mentioned the 7557. I'm not sure which you're asking about (or even if both exist), but if you want to find out about NVMe support, one usually reliable way is to go to support.dell.com, search the model of your PC, and then go to the Manuals & Documents section. In there you'll find usually find a few documents. Sometimes you'll find just a User/Owner Manual, and sometimes you'll see that as well as a Service Manual and a Specifications document. Different models are different here, but at least one of those will have a Specifications section in the document that will usually tell you if the system supports NVMe/PCie SSDs. That's generally something you want to check BEFORE you buy an NVMe SSD, though.
Additionally, there have been multiple reports of the 970 Evo specifically being a problem with some Dell systems, even systems that work fine with the 960 Evo. I've remember that some XPS 13 models seem not to work with the 970 Evo, although someone else recently installed a 970 Evo into his Dell G5 laptop and it worked fine. I would check the "System summary/information" of your BIOS Setup interface. If the 970 Evo isn't listed there, then changing between AHCI and RAID mode won't make a difference. The system simply won't support it at this point, and unfortunately at the moment it's unclear what the underlying cause of this issue is for other systems where this has been observed. Could be system firmware or SSD firmware, but to my knowledge there hasn't been a fix yet.
Disable Secureboot, enable AHCI, and when you install Windows 10 make sure that the hybrid drive is disconnected before you start the system. Install Windows 10 with only the NVME drive connected. And I would only use the Windows 10 USB that was setup with the Microsoft Media Creation tool. Is the drive detected in the BIOS? Restart the system and at the Dell splash screen start tapping F2. Look in the BIOS to make sure the drive is detected. Now having said that, I have the Inspiron 5575 and my M.2 drive is not detected in the BIOS, yet Windows 10 installed without a hitch and boots and runs perfectly...so go figure.
Thank you very much. I will do that soon. I have one question, How can I learn that if my laptop 7557 supports NVME or not? Is there an official document about that for a specific model? Regards
It is 7559. I made what you suggested.also created usb as it is suggested in the links.windows starts from usb now hopefully to install itself to the system however the windows installation doesnt detect any harddrive except the usb itself ( i unplugged hybrid one,left only nvme)
I am grateful for your answer but there is a design stupidity in samsung evo models. If there are two different protocols for ssd why the slot pins for these ssds are same? I can plug that thing to my laptop but i cant run it. This is so stupid. Ide and sata slots are different so you can not make a mistake.why these butchers( i wrote it wrong knowingly) changed the slot design? I guess this fault is shared by dell designers also... dont know the percentage.
Anyway, thank you. I guess since the ssd fits, this can be fixed with a firmware update to bios.
If it doesn’t support NVMe now, a firmware update definitely won’t add it. Supporting NVMe requires having PCIe lanes wired to that slot, and if the system had that, then there wouldn’t be a reason not to support NVMe already — so if it doesn’t, it’s probably because it only has a SATA interface routed to the a slot, not PCIe. As for using the same slot type for different interfaces, there are other examples of that in the PC industry, but actually M.2 NVMe and M.2 SATA are slightly different. M.2 SATA SSDs have two notches in their connector, whereas NVMe SSDs only have one. That means that motherboard manufacturers that have M.2 slots that only support SATA could add two plastic tabs in the slot so that NVMe SSDs won’t fit, but it seems not everyone does that.
I’m still waiting for a universal external adapter for these SSDs. Right now there are M.2 SATA to USB adapters (and enclosures) and M.2 NVMe to USB adapters and enclosures, but none I’ve found that support both, and I want maximum versatility because I would use them for data recovery and migration scenarios.
Just as a check, there were issues with the 970 and windows 1809 Oct 18 upgrade that Samsung had fixed with a firmware update. would this have anything to do with the 970 having issues in the systems mention in this thread?
