T7600 - NVMe supported?

The Precision T7600 parts page shows the following SATA3, 2.5'", 7mm SSD so we know that they are supported as boot drives =

KTM9M 256GB Micron

HHCWG 512GB Liteon M3S-M
2XFM1 512GB Liteon M6S-T
HN71H 512GB Liteon M9S
3YYV3 256GB Liteon L9S
DFVVG 256GB LiteOn Vangogh
X9HG1 256GB Liteon Vangogh
WKFTG 256GB LiteOn Vangogh
XFJWX 256GB Liteon M6S 
W18WD 128GB Liteon Vangogh

P4GHK 512GB Samsung SM841
V622H 256GB Samsung PM830
YRK2P 256GB Samsung SM841N
FFKNK 256GB Samsung PM841

Not sure about the two you listed though.

Thank you very much for your response..

Yes indeed SATA III is supported (Although dedicated to optical drives, while HDD drives are SATA II.. Don't understand why???)

But the models I'm asking about are NVMe PCIe 3 x4 drives (one with adapter, the other without..) So they're not using SATA, and they need NVMe, and I don't know if that's supported in the T7600 bios or not, and if the drives will actually succeed to be boot drives..

The documentation says the Bios can be either legacy or UEFI (the latter is requred for NVMe) but doesn't specifically say any thing about NVMe being supported or not..

Unknown. This system is from 2012 and I do not see any notes about NVMe on its internal documentation.

Thank you very much for all your effort, I really appreciate it..

I'll have to wait and see if someone has a more definitive answer..

Nothing built in 2012 will have NVMe support.

You CAN use an NVMe drive but will need to install it in a PCI slot.

Short answer is No and there are no UEFI NVME Bios settings. You also do not have PCI-E 3.0 bus.

Thank you for your responce @SpeedStep,

According to the spec sheet - he model supports PCIe III:

, and regarding UEFI this is a quote from the "users Guide of the T7600 - page 48:

Thank you for your response @ejn36 , Yes - I realize that I need to Use PCIe slots, the SSDs I asked about one of them uses the PCIe directly (the Intel 770), and the other (950 pro) needs an adaptor..

I know that the drives can be used, the question was more about whether or not they can used as Boot Drives..

It is possible to have Class 1 or Class 2.0  UEFI.   Class 2.3.1  or 3 UEFI isnt the same. The INTEL C600 Series Chipset does not support DUAL X16 slots AND NVME PCI-E 3.0.  You do not have INTEL97,99, 100 Series Chipset and therefore the answer is No you don't have it and No you never will.

Using an NVMe device to boot a computer system requires the following:

• A system BIOS configured to enable uEFI* version 2.3.1 and support NVMe boot
• A system based on an Intel® Z97 or X99 Chipset
• A 64-bit operating system that supports UEFI 2.3.1  Windows* 7, 8 or 8.1
• For Windows 7, the CSM in the system BIOS might need to be set
• The Intel® NVMe driver

UEFI 2.3.1 is only 1 required piece.   The chipset being 97,99 or 100 series is not optional.

The XPS 8900 has NVME and UEFI 2.3.1.

NVME is not native to windows until 8.1 and that came out in 2013.  The e in NVMe  is express as in PCI-E 3.0  the chipset on the 7600 is PCI-E 2.0

Thank you very very much @SpeedStep For all the info, I really appretiate it..

But I'm a little confused though.. these are some snapshots from the BIOS settings, maybe they can shed some more light on the matter:

I don't know which UEFI version is it ??

Again I'm really grateful to you for taking all the time and effort..

Speedstep, you are partially incorrect. You do not need specific chipsets. I boot NVMe on a Precision T5500 using Tianocore UEFI emulator. This machine doesn't even have PCIe 3.0, so i do lose some performance. You can boot this from a drive, cd, or USB. However, I have tested it on the T5600 and the built in UEFI conflicts with the Tianocore UEFI so it hangs. This is probably true for the T7600 as well. I just wanted to clarify for the other readers that NVMe is in no way dependant on a chipset. In fact there is a guy named Juha I believe who ripped the bios chip off the T5600 motherboard and inserted the 3 minuscule lines of code that enable NVMe into the BIOS and re-attached the chip. If Dell didn't sign their BIOS we could have just flashed it and everyone could enjoy NVMe. It's really sad that these older machines are left in the dark because Dell can't make a minor bios update, when in reality they are great machines. My T5500 with 2x X5690's destroys most 6th gen i series CPUs with ease, the PC feels so fast.
