Envy 750se capable of M.2/NVMe use?

just did a clean windows install to the disk - however now the situation is even more strange.  I'm able to boot but it takes literally 2 minutes of staring at the HP logo and then the machine boots to the NVMe 950 pro!!  Once it boots it seems to be really fast but the startup time is killing me...should I enable RAID in the bios rather ACHI?  Don't know what else to do...

Envy 750se capable of M.2/NVMe use?

Take a look through this thread.  Folks there are trying/have accomplished replacing their drives with various devices.  PCIe, NVMe, etc.  IF this MoBo supports NVMe, I think you'll find the answer in there.  Please keep us updated.  I am having more issues with the XPS so it has taken my time away from the Envy.  I have had no issues with the 750se other than a fan constantly speeding up/slowing down at an idle.

Envy 750se capable of M.2/NVMe use?

boidsonly,

 

I ordered a 750se almost identical to yours I think (6700k, 16GB RAM, GTX 970, 512GB SATA SSD) and am looking to swap out the 512GB SATA SSD for a 512GB  m.2 SSD  (either PCIe or NVMe).

 

Do you know if that is possible? Is it even necessary or is the machine "fast enough" as-is?

 

EDIT: The 750se uses a Thimphu motherboard, whose spec says "Expansion slots: One M.2 socket 3, key M". I believe Key M means support for PCI Express SSDs with up to 4x lanes of bandwidth. If correct, the 750se might support a PCIe 4x SSD (not as fast as NVMe much faster than SATA SSD).

 

EDIT 2: The latest generation of PCIe SSD have come out in the last couple of weeks. They use PCIe 3.0 4x as opposed to PCIe 2.0 4x. These are benchmarking at faster speeds than NVMe.

@AndySm99

 

Your edit2 information is somewhat confusing and not totally accurate. NVMe performance is generally faster than non-NVMe performance.  While it's possible for non-NVMe devices to hop over some NVMe devices, the non-NVMe devices will have a limited performance future as the transfer protocol is not efficient at the higher throughput rates.

Envy 750se capable of M.2/NVMe use?

I'm trying to iron out all the issues with an XPS 15 I purchased so I haven't done any work on the 740se.  I was kind of hoping the question would have been solved/answered by the time I turned my attention back to the Envy.

  Mine came with a 2tb HDD, not an SSD; so it is imortant to me to, hopefully, have the question answered so I know what to replace the HDD with.  If it is still an open issue when I can get back to this, I'll buy whatever is available at the time and see what happens.

I know there are issues with AHCI/RAID and SSD/NVMe options, making it easy to get it wrong when setting the PC up for one or the other.  Seems to involve RST/NVMe drivers, etc.  Too much to tackle right now.  And if that were not enough, I'd like to have it ironed out BEFORE I perform a fresh install of Win10Pro.  LOL...

 

On an aside, I have Win 10 running on my HP DV6-6112nr with no issues (even have WiFi!).  Took a little research and work but it was worth it.

Yes, my Edit 2 was not good, I'll try again: The 750se motherboard/bios probably doesn't support PCIe 3.0 SSDs that use NVMe. However, the motherboard might support PCIe 3.0 SSDs that use AHCI (and these will be almost as fast, and in some instances faster, than their NVMe cousin).

Envy 750se capable of M.2/NVMe use?

i ended up getting the Phoenix 860st (i think it uses the same motherboard as the 750se.) The Samsung 950 pro M.2 works really well with it as a boot drive (for Windows 10) using NVMe for sure (Windows is indicating it is using the NVMe driver for this drive.)  It works great actually. The only annoying thing is the M.2 port on the board wasn't easy to reach and i needed to remove the graphics card (among many other things) to reach it. and there was no screw to attach the M.2 drive (it didn't come with any,) had to find one myself.  other than that, great.  I was installing Windows 10 in UEFI mode, and it was the only place the drive shows for me, it wasn't listed in the BIOS otherwise (which scared me for a little while.)

 

Please note this is my personal experince on the Phoenix 860st and not a professional opinion of what would and wouldn't work for you on 750se.

Nice build and well done.  I assume you have the NVMe in RAID as opposed to AHCI?

T_B_K,

 

Nice work! I got my 750se yesterday.

 

My rig came with 512GB SSD. Windows 10 takes 5 seconds to boot. I thought of buying a 950 Pro as well but reducing boot time from 5 seconds to 2-3 seconds is not worth the time/effort to me.

 

And probably real world speed difference between SATA SSD versus PCIe NVMe is barely noticable.

@T_B_K

 

What is the product number for your 860st? 

 

What BIOS level is your PC running?

 

What is the model number of the Samsung Pro 950 that you used?
