Here are the benchmark results.
Settings:
- CPU C1E state enabled
- CPU C2 and C6 state enabled
- Balanced power scheme
- Intel Core i7-4930K, OC to 4625 GHz (125 MHz x 37)
- G.Skill RAM 16 GB Kit, OC at 2333 MHz
- Intel RST EFI module 13.5.0.2164
- Intel NVMe driver 1.2.0
- Intel RST driver 13.6.3.1001

left: Intel SSD 750 400GB
mid: 2x Samsung SSD 840 Pro 256GB (RAID-0, write-back cache)
right: 2x WD Raptor Black 500GB (RAID-0, write-back cache)

@ mr_nuub:

Thanks for having done the benchmark comparison tests and for having posted them. Especially the Sequential READ scores of the Intel 740 PCIe SSD are awesome!
Please let us know, how you got the NVMe support working with your X79 system.
Are you able to use the Intel 750 PCIe SSD as system drive and to boot off it?

#93 RE: [Discussion] NVMe BIOS Modules and NVMe Support by mr_nuub 20.06.2015 20:35

I just plugged it in the last PCIe x16 slot, which only provides x8 bandwidth.
I did NOT modify my BIOS with NVMe modules.
The only modifications, that I did are:
- RST OROM
- RSTe OROM
- RST UEFI module
- RSTe UEFI module
- PXE OROM
- ASmedia SATA OROM
- CPU microcodes (SB-E/IB-E)

And I am able to boot Windows 8.1 off the NVMe SSD. As I wrote before, I disabled all SATA controllers in BIOS
and installed Windows using a USB thumb drive. I also used the Intel NVMe driver for the installation, so the MS onenever got used.

Thanks for your quick reply.

None of these BIOS modules has an effect on the support of your Intel 750 PCIe SSD.

This is a surprise for me.

#95 RE: [Discussion] NVMe BIOS Modules and NVMe Support by mr_nuub 20.06.2015 20:58

Yeah I know, that none of these modules have an effect. I just wanted to list the mods that I have done.
It seems that some boards support NVMe and some simply don't.

I am just a lucky bastard :P

#96 NVMe-Support: Only drivers or EFI-modules necessary? by Ludolf 22.06.2015 15:22

Hello folks,

my question is: What is necessary to use NVMe on PCIe-SSDs?
What is known: Drivers in OS are required.

But i don't know, if EFI-update for NVMe-support is mandatory. Is NVMe a module in EFI and always necessary?

Concrete, i do a little Apple Mac-stuff. The old Mac Pro has PCIe-expansion slots and many users upgraded the machine with PCIe-SSDs because lack of SATA-3-Ports (only SATA-2 is possible, thats ok for HDDs, but SSDs are underrated) and it can boot from this drive. The latest OS got NVMe-drivers, but i don't know if it is usable without EFI-modul. The Mac-EFI is very similar to PC-EFI, but much harder to understand, because Apple did their own thing in engineering.

Thanks for discussion!

You cannot boot from the NVMe drive without NVMe module.

I am not sure about that.
>Here< is the report from our Forum member Mr_nuub, who was able to boot off the Intel 750 PCIe SSD wth NVMe support without adding any NVMe BIOS modules.
He has an Intel X79 Chipset mainboard.

#99 RE: NVMe-Support: Only drivers or EFI-modules necessary? by Jest 22.06.2015 16:22

I saw that a few days ago and it is definitely interesting. But, i also saw a few reports, that intel 750 is working on Z77, but is not bootable.

#100 RE: NVMe-Support: Only drivers or EFI-modules necessary? by mr_nuub 22.06.2015 16:53

Indeed it is very interesting.
I have an ASRock X79 Extreme4 board with BIOS version 3.70.
It seems that the ASRock developers upgraded to Intel ME 8.x to support Ivy-Bridge-E.
In turn they updated the UEFI to support Intel ME v8.x and forgot to remove the NVMe driver code.
For further detailes read CodeRush's post >here<.

EDIT: According to Microsofts Device.Storage Requirements, only PCIe 2.0 is requiered (to use the MS NVMe driver, I think...).
The document can be found >here< (scroll down to "Device.Storage.ControllerDrive.NVMe").
So in theory every PCIe 2.0 compliant mainboard/processor can be used to get a NVMe device working as data storage.
To boot an OS off it, there must be an UEFI driver for NVMe (be it integrated in some other module, TianoCore or EDK2 based).

@ Ludolf:

Since there is already a thread about the topic "NVMe Support", I would rather like to merge this thread with >this< one. It would make it easier for visitors to find an answer to their NVMe related questions.
What do you think about this idea?

Thats the point: Is booting possible with NVMe-support? If not, perhaps it is recognized in AHCI-mode and the loaded driver of the OS enables NVMe. I read a few postings, that it isn't possible to use NVMe-based SSDs on some mainboards as a startup-volume until the BIOS got an update.

Fernando, that would be ok. You can merge both threads.

Done!

My mainboard has no dedicated NVMe UEFI modules or legacy OROMs.
Legacy boot is not possible, since it is not detected due to missing OROM.
It is not recognized as AHCI, nor as IDE. There is only an "Intel Corporation Mass Storage Controller" displayed in my UEFI System Browser (ASRock feature).

Since you are talking about an Apple system, I really don't know if it is supported.
AFAIK the 12-inch MacBook (early 2015) is the only NVMe compatible system out there.

hi!
i have an i7-3930k with a sabertooth X79 and as many of you i will buy intel SSD 750
despite of many web reviews that says it is incompatible!

as soon as i wil buy it next month i give you a report!

meanwhile i have found others test on X79 platform

bye!

PS: i think that PCI-E Version intested of 2.5"" as internal nvme efi module as old OROM of classical RAID controller ....
