@Wickedt - That's not how people in PC world speak, and if he used that as an excuse in court a lawyer would tear him up. "Works at x16" means just that to anyone that sells/uses these things
Someone with similar drive and working x8 or x16 adapter would need to test for you to find out what you should expect and PCIE 2.0 vs 3.0 while also limited at x4 vs x8/x16 etc.

Did you try the BIOS I posted for you and adjust lane widths and recheck to see if you can get more than x4
I do see your speed look nearly what people describe you should expect from PCIE 2.0 x4, maybe a little slower though, based on these two pages

I would play around with the BIOS I made for you and see if you can get x8 working or not.
With that BIOS, you could also limit an x16 graphics card to x8 or x4, to confirm the settings per the slot you want are working and the setting you are adjusting is the correct slot you wanted. I'd do that first, so you know which setting option is which slot

Bios updated to v7
Changelog:
[Changed] - EFI LAN Intel PRO/1000 UNDI v8.4.09 -----> v8.5.21
>ASUS-Crosshair-V-Formula-Z-2201 MOD v7 (2018-11-25)<

A 970 evo is 4 lane pci-ex device putting it in 8x slot is not going to magically change it into 8x lane device. So in a Crosshair Z with only pci-ex 2.0 you are only every going to get about 2GB/s.
I knew this before hand so i bought a cheaper pci-ex ssd for it, though I am very happy with a 2GB/s boot anyway :up:

The adapter cards are passive devices that just route wiring and change slots...no active conversion is going to happen

@Bitey

You are right. I didn't know the specs of the 970 Pro and i don't have one but i was assuming that it was able to run at more than 4x. But now that i saw the specs of the 970 Pro, i can see that it is officially capable of running at a maximum of PCIe 3.0 x4.

So this means that the Crosshair Formula (Z or not) can reach a max speed of PCIe 2.0 4x with this drive.

Thanks to @SpaceRanger1 for sending me the specs of the 970 Pro by pm to clarify that point.

The literature on both my PCIe cards also tell me in the PCIe 2.0 (Z) motherboard I have. I'll only get 16g Max.... Now the PCIe 3.0 motherboards will get the FULL 32g.
Anyways (PHOENIX48) Thank you for ALL your help with my moding...Its been a test of my abilities and you whizzed me threw it with GREAT success!! Much
appreciated!!!!

Looks like you were able to provide a solution for some people. Sadly it isn't working for me. I flashed my Bios with the USB Flashback feature and it installed it correctly as far as I can tell but the motherboard isn't able to display me the PCIe card with the nvme SSD in Windows nor as a Boot option in the UEFI.

Then I tried the SSD in my old Foxconn Flaming Blade and it showed me the SSD properly even though it is much older.
The SSD which I tried to connect is the Viperteq gaming series 512gb M.2 SSD.

@Geist

If the NVMe module don't seems to detect and support your drive, you may try to change it by replacing it with an older version of it. It can sometimes change the compatibility. The module in the current v7 Bios is the latest NvmExpressDxe_4. But you may try to replace it with any of the 3 older versions of the module. It is kind of a long shot that may not work either but this may be worth a try.

More details about the module and how to change it can be found here.

So quick question. This is my first time ever flashing your bios mod and i jumped straight to v7 is that okay and will I get all the other updates included in v1 up to current v7? Also is there anyway to tell if the mod is working or just as long as it flashed and booted afterwards? Thank you!

@Poolshark28

All updates since the beginning are included in the last version v7.

You know it is working when it boot. As for another way to know if it is working, it depends what your system was before and after a Bios flash. Example: A system still on original Bios before will know right away that the new bios is there because the new AMD AHCI module will show up at boot (assuming your drive use AHCI).

Awesome, I should be good then because mine now flashes a black screen with white achi writing when first booted for a split second then PC boots up normally

@Geist - NVME wont show up as bootable device or by name in the BIOS, only PATA or PATA SS, and then your install source must be GPT partitioned USB and then make GPT partition on the NVME once you get there (or before with diskpart)

Also, for someone interested to update the ASmedia 1042A USB controller I'll post the latest firmware (140124_10_10_04), thanks to Fernando for dumping it and Staveley to fix its size. This mobo has 3 ASM1042A USB controller chips, with current firmware 130704_10_02_01. This update helps with file transfer speeds, you have to create a bootable USB stick drive or SD card (for DOS) and paste the contents of this file. Then, you just run the included bat file to upgrade your firmware (u.bat to update & d.bat to check the firmware).

Here's the file:


Edit: Don't forget to disconnect all your USB devices (except your USB pen drive) before flashing...

Possible this mod could be don for the Asus M5a97 r2.0 also?
like the ahci module and nvme stuff?

@fr0tch

You are not the first person to have this problem but you are the first person that i know of to have this problem with the Z version... I explain:

Usually, but rarelly, once in a while there are some people reporting having a 1042A chip in a Formula (non-Z) instead of the usual 1042 chip. Everyone always assumed that Asus run out at some point of 1042 and put some newer 1042A untill either the 1042 stock got up again or untill the production of the Formula was completed and replaced by the Formula-Z.

Anyway, all this to say that you are the first that i am aware of that it is the other way around with a Formula-Z instead of a Formula.

In any case, because the problem is more frequent and already well known with the Formula, i suggest you see the last part of the first post in the Formula (non-Z) thread instead. everything you need should be there.

@empilein

As long as your AMD SATA AHCI controller is reported in Windows as being DEV_4391 then yes, the AHCI option rom can be added if it is not already present in the Bios.

As for the NVMe module, it is more only a question to see if there is enough free space in the Bios to put it there. It is usually, in most cases, not a problem.
