5090 FE PCIe Issue Need Help!

[Quartz]

So it’s dead, I managed to get a hold of a 5070 temporarily and booted straight up.

You need to verify this by trying the 5090 in another machine. Another possibility is that the 5090 isn't getting sufficient power from the PSU.

The problem you might have now is that seeing the scummy company that is selling the FE cards in the UK and how they are not at all customer friendly they may reject the RMA as you have had the cooler off, especially if it had a sticker over one of the screws. You didn't tell them you water blocked the card did you?

The FE has no stickers on any of the screws. The RMA is directly with NVIDIA.

It went from code 99 now to code 94 now. I’m fairly certain it’s a PCIe issue on the GPU side. But I agree, this is a possibility too, although quite unlikely.

Just verified, PSU working fine

Hi guys. I have an issue, possibly with my 5090 FE. The issue:

- I am running a water cooled system, the 5090 FE is in a waterblock
- I keep getting code 99 on my x870e Nova as it’s booting. It indicates a Super IO initialization error with something in the PC.
- I’ve unplugged every USB device and slowly added them back on but narrowed it down to the GPU.
- It boots fine if the GPU is unplugged and I boot on integrated graphics
- I took my card out cleaned the pcie connector and slot. Put it back in and worked for hours, I gamed and worked no issues. Powered down, tried powering up again and it went back to getting stuck at code 99.
- It is on a riser cable this might be the issue. I forced Gen4 didn’t make a difference.
- It’s weird, every 10 to 20 boots, 1 boot will get me to desktop and PC will work fine through the GPU
- In Minidump files they showed 2 errors such as: 0x116 VIDEO_TDR_FAILURE error and 0x50 PAGE_FAULT_IN_NONPAGED_AREA

Only possible remaining solutions I can think of troubleshooting (waiting for soft tubing to arrive to sort as running acrylic tubes):

- Plug GPU directly in the PCIe slot: riser cable broken if it works consistently (soft tubes needed, I don’t to bend another acrylic tube for a while lol)
- If top did not then plug riser into lower PCIe slot to check if top one is busted
- Ask NVIDIA if I can buy a replacement PCIe connector, that may be the bit that is failing
- If solution above worked or didn’t work a new motherboard and verify that motherboard itself was not compromised PCIe (although I feel this one is highly unlikely)
- Something gone wrong with my GPU, RMA with Nvidia (but it does not explain that it can work for hours and then not initialise properly on following boot)

Sorry if this was a long one, but don’t want to spend more if I can resolve. If any has had any issue like this, some tips would help

i had a super IO problem in the end it was a set of led strips on the back of my tv that wouldnt let the pc post removed the usb from the tv and pc never should super IO ever again . might not help you but it helped me..
