Good day! Does anyone know of a good way to identify which PCI Lane is assigned to each physical PCI slot. Scanning system logs, System Info, etc. it is easy to correlate which PCI lane, GPU #, GPU serial number, etc. fell off the bus. But is there a way to correlate PCI Lane to actual PCI slot? Short of me logging the GPU serial number as I add each card to the board, It would be nice if there was a one stop shop to display GPU PCI slot information.

I don't believe that they are assigned sequentially during system boot up because I have seen lane assignments go from 1, 2, 5, 6, 7, 8. It would really help in troubleshooting riser problems if physical slot assignment was easily found.

I have learned over the years that riser board version type really does not matter (even though I have seen several posts that claim v6 is better, v7 is better, C vs. S, etc.). It all depends on where each lot is manufactured and if they had any kind of quality assurance check prior to shipment. Heck I have an allotment of v1s from the BTC mining days that still work great. Some riser boards work fine if the card is not overclocked too high. But it is never the same across the board.

Whether the risers are purchased from eBay, Newegg, Amazon, Craig's List, etc., it all seems to be a crap shoot. And returning products across the ocean is real pain in the a$$. My recommendation is find one vendor that has not failed you and stick with them (regardless of the wait time)...and order EXTRAS! Does anyone know of a US, UK or Asia based reliable vendor?

Just some food for thought from an extremely happy nvOC user.

I identified them by setting all fans to 0 and popping them up to 100 one at a time.

This is a good method; I am going to start using it.
