@Fernando
i am pretty sure that it have been mounted exactly the same way in the M2 slot as with the second attempt. It has to be some micro-movement on the contact. Anyhow Windows is without any issue bootable.

Hello. I do everything according to the instructions, I reached the moment of installation in the BIOS through the "MMTool 4.50.0023" file " NvmExpressDxe_Small.ffts" and I get the message "file size exceeds the volume size". With the file " NvmExpressDxe_4.ffs", the same thing. I attach screenshots of errors and the BIOS file. I hope for help. Thank you in advance.

Thank you so much, everything worked out. It's good that there are people like you. I wish you success in the future.

DrQuake,

What is the motherboard model you have?

Hi all,

First of all, this is a great forum on which I already gathered a lot of knowledge for the past two weeks, but still not able to get my ssd PCIe working :(

The ssd seems to deconnecting itself when writing a huge amount of data to it.
Have no clue what is causing this behavior. So created an account and here is my first post :)

Some specs of my system:
Motherboard ZH77A-G43
Intel 7-series
SSD Toshiba KXG50ZNV256G NVMe PCIe M.2 256GB (PCI Express 3.0 x4) connected on a PCIe 3.0 x16 card
Previous my graphical card was added into that PCIe slot, but removed it temporary from my computer to exclude any impact.
2 HDD sata drives (one with windows 10 professional as booted system and another one with data connected to SATA3)
Installed the "pure 64bit OCZ NVMe driver v1.2.126.843 mod+signed by me (at 07/28/2019)"
Installed >64bit Intel RST(e) AHCI/RAID Drivers v13.1.0.1058 WHQL<

I updated the BIOS to the newest version and added the NVMe modules as my motherboard was not NVMe compatible.
This change was successful as I could see the ssd in the boot options overview.

The next step was making a clone from my hdd to the sdd drive. This was running fine until reaching around 1 GB. At that point it was hanging my system and mentioning bad sectors (used several clone progs).

I have also tested both hdd and ssd on bad sectors, but everything is fine so don't think the drives are causing the issue.
ALso tried the clone program via USB boot whitout luck.

I have also read something about issues when working with SATA and PCIe/m2 together in one system.
So I disconnected the SATA drives and tried booting from usb to install a clean windows 10 installation on the sdd.
I succeeded after several attempts. Booting from ssd went fine, but after some minutes windows 10 was freezing again :(
So cleaned the ssd and tried again, but didn't succeed anymore in installing a clean windows 10 on the sdd.

Booted windows 10 again from the hdd on SATA3 and created a simple volume on the sdd drive.
Copy small data to the ssd works fine, but copying data of around 2-4GB will disconnect the drive.

As last step, I tried checking the ssd using CrystalDiskInfo. The read on the ssd gave me around 2700MB/s which looks fine, but the write will again disconnect the drive.
In the windows error log I could see an error like "Device raidport1 has been removed".
Not sure if this is meaningful as my BIOS SATA is set in AHCI mode and not in RAID mode (or I am using wrong drivers...).

Also did some other tweak which I found on this forum as disabling LPT, but without change.

This is like my last resort to get this issue solved before smashing the ssd as I am out of ideas :)
Any help is very appreciated.

Already thanks!

Hi @Fernando, @lfb6

Installed the new BIOS version as described in your guide and indeed I can see PATA in the bootable discs.
So far so good I thought as writing/reading to the sdd (pc booted from SATA HDD wibndowas 10 Pro) is still freezing my pc.
Currently using the standard windows AHCI and NVMe controller.

I tested the write with CrystalDiskMark. Writing small files to it is no problem at all.

I will do some more testing and see if I can get some logs...
Any ideas already?

Thanks in advance,
Andy.

Good evening everyone!
Here is my problem to solve:
Recently I've bought SSD Adata XPG Gamming S11 Pro, 1 TB and one NVMe/PCIe adapter. My motherboard is GA-P85-D3 and hasn't native M2 slot. The SSD is visible in Windows 10 but not in UEFI BIOS I have. When I try to install W10 on it an error pop-up, informing me either my disk is in GPT and W10 can't be installed there, either (after I made it MBR) - it's not possible unless I activate the relative controller in BIOS. But I am not sure which controller and setting it should be that... So I've end it here as last resort, to make a modified BIOS.
I've downloaded all tools and two .ffs files but when I try to insert .ffs, for bigger ones I am receiving message "The file size is too big", and for smaller ones - "Error inserting". Followng instructions I will upload here my latest BIOS file and hope someone could help me with that.

Thanks in advance!

Hi Dieter, nice to see you respond so fast, thank you!
I've been following the first post instructions and obviously didn't see this option... Now I tried again and it worked! So I hope everything with flashing to be OK and to have my new SSD working as it's to be.
Once again - you have my gratitude!
I'll post again after successful flash. I hope...:)

@Bigbobby753 ,
I have the same motherboard as you, but I don't succeed in getting my ssd nvme properly working and it is keeping me busy now for a while :(
The problem is that my ssd is disconnecting itself for god knows which reason. Even a bench testing is freezing my windows 10.

I already flashed my BIOS with the same version as yours and tried again, but no luck either.
So I was wondering if you came across this kind of issue?
Also maybe you have done some tweaks in your BIOS?

Thanks in advance,
Andy.

EDIT by Fernando: Unneeded fully quoted post removed (to save space within this already very voluminous thread).

I suggest u do a clean install of the OS on ur new NVMe, reseting bios values, setttings for NVMe booting as described in guide, standard NVMe driver from MS and IRST 13.1, no other attachaded drives, i presume ur using slot 1 above 1st PCIex16, use the 2nd PCIex16 instead, only this way u can trace HW/Driver, resource allocation issue on a fresh OS, ur M.2 PCIe adapater...wich we dont know...is also a suspect on the list. is there any avaiable FW to ur TOSHIBA M.2 NVMe?...check it.
