In that thread above a poster said:

"If you short out pin A1 and B17 on the x16 slot the motherboard will not power on. You MUST short out pin A1 and B81 - B81 is the second to last pin at the very end of the slot."

So from the picture in this demonstration how would I do it in a 16x slot?
https://bitcointalksearch.org/topic/list-of-motherboard-that-require-shorting-pin-a1-b17-for-pci-e-1x-to-work-36061

Would I do the same put one side in the pin A1 and the other in pin b17 or would I do pin A1 and then the send to last pin of the 16x slot.

Thanks

In what devices or cables can I find those wires and what do they look like lol


Can anyone answer this since I have same question and prefer not to fry my MB. Thanks in advance.

Thanks for the link.

I use the wires from a CAT-5e networking cable. Gotta sacrifice a cable to get 'em, but they're just about perfect. Have fun fitting them in the holes!  Tongue

Same pins need to be shorted be it 1x or 16x.

Where were you able to buy the Asrock motherboard? Can't find them anywhere.

Hey guys I was curious on how to jump a PCI-16x slot on my motherboards.

The motherboards seem not to recognize the GPUs using a powered riser in the 16x slot.
I have found 1x slot jumper instructions but not the 16x. My 1x slots work fine without needing to be jumped. I currently have 5 GPUs running on both. With 2 power supplies on each.

Motherboards:
- Asrock H81 BTC Pro
- MSI Z87-G45

Thanks
