Aurora R13, PCIe x4 slot not working?

So, this is following up on the Elgato 4K60 mk.2 capture card not showing up when installed on the top x4 PCIe slot.  Been troubleshooting this with Elgato and at this point they haven't been able to find a reason it why it isn't working in the R13. 

I finally fished out my NVME PCIe adapter, put a working NVME m.2 drive on it, and that isn't showing up at all either.  It's getting power, just as the Elgato card did, but isn't showing up as it does in the other system (same with the Elgato).

I'm on the latest 1.08 bios and I don't see any options to manage the PCIe slots.  Any suggestions would be greatly appreciated.

I am waiting on delivery of a PCIE NIC from Dell for mine. They even asked me the service tag of my machine so assuming this means that the NIC will be supported by the Aurora R13. The NIC is an Intel rather than the ROG that wont work. As mentioned in my other thread, the ROG works fine on a PCIE 4x port on a Dell Precision 3640

I can't pull any pertinent info from Belarc. I don't believe the statement "it's proven to be working fine with other devices". What other devices?!? I put a generic NIC in my system and every single Windows machine I put it in auto identifies it. A NIC isn't specialized hardware. And yet this system simply won't see it. If there is legitimately something else taking the resources for the top PCI slot which essentially disables it, then say that. Tell everyone there is a forced trade off and what that trade-off is. It would have been nice to know that ahead of time, but I can live with a factual statement about the cause.

What I can't live with are generic made-up excuses with zero evidence. I've been hand building computers for almost 40 years since only DOS/Command line was a thing. When a slot on a BUS isn't working, it's a jumper, a BIOS setting, or resources being unable to be shared like IRQ's.

Let's see a fully supported DELL NIC or expansion card working in that slot and show us all that it does work. Or provide a full technical reason as to what is going on, and what, if any, tradeoff there is. For what these systems cost, how do you not provide full disclosure???

Sorry, I missed that it was an ASUS ROG. Is it a combo card with NIC and WiFi AIO? I tried Googling it but couldn't quite tell.

My NIC card is as generic as it can get. I just can't fathom any reason it wouldn't at least be seen as an unidentified device with at least an alert indication in device manager. But if I have to buy a certified DELL Intel NIC then so be it. I just feel bad for the people who have high end video capture stuff or similar because Dell won't have something for them in those cases. But that should be made clear before purchase.

So, thee reply from them is based on the assumption that because the card is getting power and can be used as a pass through device, and the GPU is not installed, that the device is working.  I clarified it a little better for the support teams.

This is with a sata hdd installed, and no nvme slots being used at all.  Just the sata connection and the GPU that came with the R13.

As you can see, there isn't any PCIe x4 usage being shown, as there isn't anything plugged in.

Here is the same configuration, except I added the pcie>nvme adapter with a m.2 drive, installed on the top x4 slot.  The slot is being shown in hwinfo as being populated.

Here is the device, no id, and is not detected by device manager, nor my forensic tools.

So, why is the nvme slot being labeled as a graphics port, when it's for a m.2 device?  Why aren't the other device(s) being identified when they are populating that x4 slot, with or without the nvme slot being used?

So here I am right now...  

 

This is with the m.2 drive that was shipped with the R13, in the nvme slot right above the PCIe x4 top slot.

As you can see, it's for some reason showing that it is in the PCIe 4.0 Graphics Port > PCIe x4 Bus #2.  While the PCIe/NVME adapter with an m.2 drive on it is activating the PCIe x4 Bus #3, but will not show up in device manager, or forensic tools I have.

I am wondering if these slots are being intentionally disabled on higher end graphics configuration or the slot power being limited (despite what HWinfo says) because of the load limit of a 3080/3090 config is approaching the limit of the 750w PSU. I do know that the elgato 4k Pro Mk2 has a draw of 6W (they don't specify if this is load or idle). So maybe if people with working Slots could post their configs it would confirm or deny this hypothesis.

hello,

i've got a similar problem : I bought an ADATA XPG S70 BLADE NVMe SSD.
It is not detected by the ADATA TOOLBOX software, neither is the integrated Western Digital NVMe that was integrated by Dell in my PC.

The only disk that the software detects is the SATA SSD I added to the PC.

It seems there is something in the software blocking the access to those devices connected on the PCI interfaces

That could be an explanation. These cards should draw up to 75 Watts from the PCIe slot, so maybe that is why it is disabled.

It's not being disabled per se.  The slot is still getting power.  Also, it's not limited to higher end GPU.  I put a 980ti (max 250w) and the results are the same.  I've been sending a lot of info on how the board is handling each slot, etc., and the engineers have the info and are taking a hard look at it to see what's causing the problem and working on a solution.

Same.  I already did that as well.  We know the card is being detected because it's showing up as populated in hwinfo.  What we don't know yet is why it's not being identified by the system.  Also, if you look at the screens I posted, the SSD is showing up as being in the x4 Graphics Port, which it isn't.  It's supposed to be labeled as Solid-state drive slot (M.2 PCIe SSD0).  The second nvme slot is being named that, and it should be Solid-state drive slot (M.2 PCIe SSD1).  So, there's something going on for sure.  They are aware of this info, and they are looking at it.

I got this from support: Could you check if the device you are connected shows up on the diagnostics test. <-- (Link to a YouTube video explaining) Once the test is done, click on the arrow that will come up on the bottom left corner of the screen to access the Advanced Menu and then go to the Configurations tab. Check if the device is seen on the X4 ports and let me know.

Having the same issues with an ElGato 4kpro installed on the PCIE slot directly and not showing up at all. I can passthrough it fine, as it gets electricity, but not recognized by the PC or anything. Funny enough like another user on this threat, I also ADATA Blade s70 drive and it wont be recognized under a PCIE/NVME drive either. I'm guessing this is probably a bios issue - but in BIOS we cant even change any settings for those slots

I agree with the bios issue, and I hope that's what the engineers are seeing as well.  I just got an update and they are working on it and hope to update me in the next few days.
