Question able this riser - are the pins bridged?

[Rent-A-Worker]

Hi all, question for those familiar with PCIe pins and gpu riser, I have question about this riser I bought from ADT (official seller)

 

There seems to be a strip that connects alternating PCIe pins, on both side of the riser. This appears different from a riser I bought from them before. Pictures attached below.

 

Should I try using it? Is there a safe way to test it without frying my motherboard?

 

Thanks in advance!

 

PS. The first two are images of the riser in questions from either side, and the third is comparing the new and old riser.

Looks like a grounding trace for the ground pins, why it is down there I don't know. It shouldn't be an issue though, because none of the pins in the slot will touch the trace when properly installed.

Edit: I checked with a pinout diagram, the bridged pins are all ground.

Interesting. Could you share the pinout diagram here? Or point me in the right direction? I’ll like to learn more. Thank you

https://en.wikipedia.org/wiki/PCI_Express that should provide you with a good overview.
