GA-990FXA-UD3 R5 - issues with pci-e X1 slots

[sabotag3x]

Hello miners,

So, I've a GA-990FXA-UD3 R5 and my PCI-E X1 slots aren't working

Error 43 or the device doesn't shows up on device manager.. That only happen on the PCI-E X1 slots..

Isn't the risers, windows(10), BIOS & video drivers are updated.
Isn't the PSU, I've a wattmeter and isn't on the limit.

I've tried to connect all GPUs or just the X1 + X16, I've tried to enable/disable IOMMU, ehci and xhci as well.. Tried to disable everything that I don't use like audio and the result is the same..

I'm using NVIDIA cards btw..

Any tips?

Thanks!

So, you haven't found any successful configuration where a card connected to a physical x1 slot is correctly detected?

You may want to look into the A1-B17 pin shorting that was necessary on a good handful of older motherboards.

Back around 2012, I had an ASROCK n68s-UCC motherboard that needed it in order for the x1 slot to be used with a riser.

I don't know what happened, maybe I've burned both x1 slots?

If the x1 slots used to work fine without an A1-B17 connection, then I don't think shorting them will solve your dilemma.

What has changed since they were working?
