About 12 good Mississippi seconds should do it

Give the BCM more time to take control before powering on your computer and/or try using the open drivers.

I'd check your power cables to ensure they are fuly seated and the pcie cables, clean em a bit if you have to.

I'm using Ubuntu 24.04.3 LTS, NVIDIA-SMI 570.195.03, Driver Version: 570.195.03, CUDA Version: 12.8

Yeah, was a boot sequence issue mostly, the BCM needs time to take over the sxm5 card

That did not work :( I was able to download the VBIOS

If he gave me that as a reference to what others have done, this might be a DGX H100, i've tried dumping the rom to get more clues but it seems pretty locked down, im going to try and use that nvflashk in a live iso and see what i can do. Anyone have access to the latest H100s DGX rom files?

I'm having a hard time finding out what the original OEM manufacturer was. It has to be one of these and most of the links go to firmware. Some packages, not all have independent firmware files that maybe(?) could be flashed? OEM Firmware Downloads But like I said I still have no idea what...

I contacted the seller, he said people had success when flashing the VBIOS, so I am looking into how i can do that.

You know what? When I was working on those V100s, I tried using this 3090 and they would just not work together at all. I removed the 3090 and all of a sudden everything worked. I think im going to return this thread-ripper for one with onboard graphics

Was sold as "They have no way to treat it" lmao, should have known. Can't return, talked to ebay already. I unmounted it to look at the pins, they look good. do I need a VBIOS flash? I don't have an enterprise account. Screenshot-20250304-231935-Gallery hosted at ImgBB https://ibb.co/G4Szp011

I can't not use the 3090 this threadripper doesn't have onboard graphics. I think the motherboard should be able to handle it, its a server class board WRX90E SAGE

tried both drivers, you can see the H100 up top there from the previous lspci command https://ibb.co/qYBzncTZ https://ibb.co/ynSTbnvV

oooh i'll give that a go

I've tried both open and proprietary. really picking them at random now, kind of like whack a mole at this point seeing if one works. I have to use an additional GPU because my Threadripper doesn't have integrated graphics, Looking at the NVIDIA driver descriptions, it should support 3090 and...

The PCI subsystem only has resize rebar support and sriov support. turning sriov support on and off does nothing different. I've tried poking around and I just asked ASUS where above 4g encoding is at, they are escalating my question and will get back in 2 days or so. I will look at the IOMMU...

yeah i tried the .run file after a good purge, still no go.

he modified it for 12v. you can see the 48v on top still there, 12v on side

System Setup: GPU: NVIDIA H100 (GH100) on an SXM5-to-PCIe adapter Motherboard: Pro WS WRX90E-SAGE SE PCIe Slot: Using a PCIe 5.0 x16 slot Power Configuration: Adapter card powered by two 8-pin CPU power connectors (Per Jungles recomendations) Operating System: Ubuntu 24.04 LTS Kernel Version...

So as some of you know, before I did the SXM2 over PCIE board with 4 V100 gpus and it was a success, that @CyklonDX initially theorized and helped a lot with. Now I pushed my cards all in and bought a H100 from a secondary market (ebay) and a SXM5 to PCIE adapter from a reputable source, Jungle...
