Subject: x670e - Can't get 1070ti's working in pci 5.0 slot

New system build december 2023:

- Asrock steel legend x670e (firmware 2.02 and latest ASRock drivers)
- AMD ryzen 9 7900x
- Gskill trident z5 neo cl30 6000 2x32gb non rgb
- Samsung pro 990 4TB m.2 incl. newest firmware
- windows 11 incl. update jan 12 2024

I can't get my MSI GTX 1070ti Gaming X or my EVGA GTX1070ti FTW2 to work in the pci 5.0 slot. I only can get my MSI GTX 1050ti to work in the pci 5.0 slot and do benchmarks. All cards work fine, incl benchmarks in the pci 3.0 slot and in my old i7 4770 system.

The MSI 1070ti starts windows but crashes hard with benchmarks and just starting rocket league.

Error messages with the MSI 1070ti are always the same loop
- volmgr event 161
- kernel power event 41 (63)
- event log 6008

The EVGA 1070ti doesn't even boot up windows, or show BIOS.
Steel legend has red "boot" and "vga" LED's on when that happens.

I've switched 3x 80plus gold powersupplies (730w, 750w, 1000w) thinking it might be inefficient power to the gpu's, but all 3 cards work fine in my old i7 4770 win10 system with the 730w and 750w psu's.

The system works fine with the iGPU, cinebench 2024 and cinebench R23, rocket league (played for an hour) etc.

BIOS settings:

I've tried setting the PCIe x16 link speed from auto to Gen3, didn't solve the problem
I've tried setting the PCIe/GFX lane configuration for x16 from auto to x8x8 and x4x4x4x4, but didn't solve the problem.

I rechecked the manual which states the pci 3.0 slot is used for x4 (pci 3.0 16x) graphic cards. But the problem is I do not have room to put a big GFX card there since the PSU is in the way and this isn't a tiny case (BeQuiet pure base 600 silver midi tower).

PCIe 5.0 should be backwards compatible, especially when I manually set it to GEN3 speeds but I think I might be erroneous here.

I used to solve most of my computer problems back in the day but this one I do not understand yet. Any help is very much apreciated !

A friend suggested disabling "fast boot" but that didn't make any difference.

1. boot up using EVGA 1070ti in pci 3.0 slot
2. change bios settings "fast boot -> disabled"
3. boot long to windows, due to bios change
4. after boot restart from windows, boot is faster than step 3
5. change EVGA 1070ti to pci 5.0 slot
6. try to boot.

No post, VGA led on steel legend x670e is red. But the boot led is not on.

The EVGA card might need the NVidia firmware update:

https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/" rel="nofollow - https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/

Put the card back in the old system to run the firmware update check.
The early 10xx series graphics cards used VBIOS, but need the newer GOP firmware before they will work with modern UEFI mode motherboards.

Thanks, according to the NVidia firmware updater it was already up to date unfortunately on the EVGA 1070ti, same with the MSI gtx 1070ti I checked yesterday on the other system.

I can run the card fine in the pci 3.0 slot in the new system, outside the computer case, if you missed that info. I'm using the system right now. But not with the 1070ti in the pcie 5.0 slot.

The MSI 1050ti worked right away first try in the pcie 5.0 slot, no problem.

Wasn't there something about pci 3.0 goes straight to the CPU and the pci 5.0 goes via the chipset or the other way around ?

Might the difference be that the msi 1050ti just goes to a maximum of 4gb of Vram but the 1070ti's go further to 8gb of Vram ?

Maybe that's why the msi 1070ti works in the beginning, but instantly crashes when giving it work to do (benchmark, gaming). The EVGA 1070ti handles it memory different or somethign sop it doesn't work from the startup in pcie 5.0.
I'm just wildy guessing.

I just want this system to work as I intended so I've just ordered an RTX 4060ti 16gb, which will be here in 3 days. If that card works fine in the pcie 5.0 slot I will be totally flabbergasted. If not, this mobo must be a defective one and I'm back to the shop the next day.

The only other thing I can think of is to check if there is an option to set the motherboard PCIE5 slot to use PCIE3 in the BIOS/UEFI.
You would not lose any transfer speed because the 10xx cards use PCIE3.

Apologies, just realised that you said you tried this already in post 1.

Here is a post by someone with the same motherboard, they had graphics card issues starting in BIOS version 2.0 but earlier versions worked better for them.
Not sure if you have tried one of the earlier versions.

I just got my RTX 4060ti 16gb and it works fine in the pcie 5.0 slot.
Now benchmarking. Looks like just a minor +36% increase in FPS for 470 euro compared to the 1070ti's, but that's a whole other discussion.

Thanks for finding that but unfortunately I had the exact same problem running out of the box firmware v1.28. That's why I upgraded to v2.02

Anyway, the good thing is, I know the gtx 1050ti and a new 40xx series RTX card works just flawless in this pcie 5.0 slot. So I guess the motherboard is fine ?

The bad thing is, I'm going to need to find a way to change the location of the psu, so I can put the GTX 1070ti in the lower pcie 3.0 slot, until I buy a newer videocard in the future.

For the rest I think I'm out of options now. I like the steel legend x670e in many ways, so a bummer to have to use this unexpected workaround until upgrading. I've been searching for/trying out different solutions for over a month now.

Several weeks later, I purchased an ASUS RX 7800 XT TUF videocard since I wanted a better gaming card anyway.

I get always crashes/freeze screens after a few minutes, can't even play Rocket League. Very strange behaviour aswell. The first 15 seconds I started a game before freezing the FPS was 15-60 everywhere, glitching like crazy. Then freeze, then full green screen or black.

I hot switched the HDMI cable to the igpu and got image again. That seems to be working always, even when the dedicated videocard in the pci 5.0 slot stops working. So windows itselfs isn't crashing, only the videocard/driver/pci 5.0 hardware.

Important info I might have not mentioned, all tests are done via HDMI, not the display ports. But that shouldn't matter much imho, just 60hz frame capping while gaming.

Extra info for previous post, I haven't used any AMD dedicated gfx card before on these systems. When installing the RX7800xt drivers on the 7900x system it noticed it already had radeon drivers for the iGPU but mentioned an update, which I installed.

I retested the RX 7800xt in the pci 3.0 slot on the x670e steel legend, which did work (completing benchmarks + gaming), but had some weird GPU spikes just sitting idle on the desktop with taskmanager open. I saw a video just now about the AMD adrenalin software doing both game recording and continues desktop screen recording, which makes it draw 100+ Watts all the time, maybe this explains the weird behaviour. Needs to be unchecked in the adrenalin settings apparently, but I did not get to that before dismantling the system.

To double check the RX 7800xt is fine I installed it in my old win10 i7 4770 32gb ram (4x8) system in the pcie 3.0 slot. Not using AMD adrenalin software, just only installed the AMD newest driver.
It worked fine, not sure if it was bottlenecked much by the cpu/mobo/ram, the rx7800xt crushed the 1070ti in compute but FPS wasn't (yet) doubled which is my goal. The most important part was it performed every task without any problem, benchmarking (unigen 4.0, cinebench 2024 GPU, passmark 2d & 3d). Zero glitches and no weird behaviour, so I guess this videocard is not a problem.

The steel legend x670e motherboard is now back at the store, from which it will be send to Asrock (hi, if you're reading this) to check if it is user (bios) error or a hardware default which can be fixed or replaced with a new board. I will respond in a few weeks when I know more.

Recap:
Videocards that worked (gaming + benchmarks) in pcie 5.0 slot: RTX 4060 ti 16gb, GTX 1050 ti
Videocards that did not work (gaming + benchmarks) in pcie 5.0 slot: 2x GTX 1070ti, RX 7800xt

The biggest difference I can think of is powerdraw, or something. But every videocard got dedicated power from sufficient PSU's all the time and all videocards work fine in my old system.

My (possible) bad, I remember I forgot to reset the bios when installing the RX7800xt, if that would make any difference. But the last videocard in the system was the RTX 4060ti 16gb, which did work and is also a pcie 4.0 card.

Solved ! One tiny bend pin (BD 3) on the cpu slot, which controls pcie.

I got an email from the store, I can go pick it up. Both myself and the guy from the store who took the board in did not see any bent pins at first glance, but rechecking my own photo's from the first day just before building I can see a different glare on the lower left pin. Did not know it was a bend, because it is so small. This was before I inserted the CPU.

Glad it got resolved fast. I know motherboard manufacturers weren't happy the pins were moved from the cpu to the motherboard, being fragile this way

Wow, good news that it is now working.

When I get an AM5 motherboard I shall have to get the magnifying glass out for checks before starting the build.

when looking for bend pins posts I found another one on reddit with the same motherboard and videocard problem:
