if you want, that I check the result of your BIOS modding work, you should give me a link to the (compressed) modded BIOS file.

Next questions:
1. How did you flash the modded BIOS into your HP system?
2. After having flashed the modded BIOS, did/do you see a Disk Drive named "PATA" listed within your mainboard BIOS?
3. Did you install Win10 in UEFI mode as layed down within my guide (= start post)? If yes, what happened?

Hi All,

First of all, thank you for the above guide. I'm now typing this message on a laptop with a supported NVMe drive!

Unfortunately, performance is a lot slower than expected (seq. read around 400mb/s. Whereas 2600mb/s advertised). I have followed other guide in this forum on optimising speed but the only reason I can think for this drastic reduction is my bios is still using the SATA controller rather than the SSD onboard controller. Is it possible to mod bios further to enable (or disable!) the controller and allow the drive to use PCIe? (or am I thinking about this all wrong?)

Any help would be greatly appreciated! Thanks again.

Paul

Laptop spec - Razer blade 2015, i7-4720HQ (I think this is the problem!), American megatrends bios (but named Razer 3.15 in sysinfo)

I couldn't find any information regarding the M.2 interface on your Razer, but based on what little information I found, I would say it's connected to the SATA bus, not the PCIe bus. If so, there's no way to change it to the PCIe bus, as that's determined by the pathways/traces on the motherboard. All you can do is check forums where others have tried the same thing.

Hi guys, thanks for the quick response and doing some digging in my setup. I've had alot of trouble finding info on this laptop too! I've been researching on Razer but unfortunately they don't realise bios updates.i will contact direct on support for NVMe for older mainboards.

As a general question, and perhaps this is something in relation more modern mainboards (mine being 3 years old at this point) but I thought m.2 ports could use either SATA or NVMe bus depending on what drive is inserted (see link below)? m.2 connection having only one slot (physical notch) while m.2 SATA only slots have 2 notches to ensure no NVMe drives are inserted to the board. (Albiet, physical connection to the board doesn't mean the hardware or bios software is there to support it I suppose!)
I will keep digging as well and see if anyone has had success, thanks for the input!

Originally a Lite-ON L9G M.2 SATA was installed and I've replaced with a Toshiba XG3 M.2 (A.K.A OCZ RD400 NVMe) Drive. Apologies I should have spec'd this in my first post.

I feel there are two possible situations with my setup -

One being the SATA controller is hardwired to the M.2 port and all controls are done on this motherboard controller. Hence my speed being limited to 400mb/s or the usual 10 SATA lanes. But this begs the question why the motherboard manufacturer included an NVMe capable slot.

Second, (and i'm hoping this is the case) my bios is not deactivating the SATA controller which is not allowing the on-ssd NVMe controller to be used via PCIe.

Would you guys picture this could be the case or am I confusing the operation between the board and ssd?

Thanks,

Paul

My understanding of the M.2 interface is that it can be used for both NVMe and SATA, but not necessarily both. Check the Wikipedia article on M.2, which is where the statement below is from.

"Computer bus interfaces provided through the M.2 connector are PCI Express 3.0 (up to four lanes), Serial ATA 3.0, and USB 3.0 (a single logical port for each of the latter two). It is up to the manufacturer of the M.2 host or device to select which interfaces are to be supported, depending on the desired level of host support and device type".

From what I found it appears that the 2016 Razer may have NVMe support, but not the older 2015. Razer clearly does not like giving much, if any, information on their laptops other than their basic features. Have you attempted to ask them regarding NVMe support on your laptop?

Hi @Paulos7
I've left a message with razor support, still waiting on a reply. I think you are correct though - the decision is all on the manufacturer as to what features have been included. Obviously NVMe wasn't on Razers feature list at the time - as you indicated the newer 2016 laptop has NVMe support.

Hopefully I can figure out if it is a hardware or software limitation. Will keep you posted if I get a response!

Best,

Paul

hi guys,
as the title says im having a lot of problem with the installation and the usage of S960 EVO as main drive on my crosshair MOBO. im a kind of noob on this things so i really love is u can help me step by step. Anyway till now i did a copy of my OS on my S960 with Samsung Data Migration and im using the ULTIMATE MODDED BIOS posted by Stickmode in his thread but when i restart the PC it saw the SSD as Pata SS on BIOS menu but on dark screen it says " Insert a bootable device and restar ".

My current System:
MB: ASUS Crosshair Formula -Z, CPU: AMD FX8350 BE, Disk Drives: WD WD20EZRX Green 2 TB Samsung 960 EVO SSD 250 GB, Graphics: Nvidia GTX 760 ASUS, OS: Win10 Pro x64

sorry if im posting on a wrong tab this is my first post.
