Please help on making the 8th GPU M.2 working on ASUS PRIME Z270 A

[a1b1C22]

Hi, Ive installed successfully everything on an Asus prime z270-a, 7 1070 gtx are working, the 8th one is not shown,
in device manager I cannot see any unauthorized device.
the 8th one is installed on one of the M.2 ports. The othet M.2 has my SSD drive. I tried both M.2 porths for the SSD drive and both are OK.
I followed setup of bios as described in many threads here(M.2.1 has auto and M.2.2 has X2).
thanks for any suggestions.

Most likely your M.2-to-PCIe adapter card is misaligned in the connector. The ones I had to deal with had the alignment notch routed too wide. At least wide enough so that it lands either too far left or too far right and the contact pads don't align.

It takes a bit of effort and really steady hands to stick it in in such a way that it lands properly. One way to check is to look closely for the notch and it's relative position to the plastic "pin" in the connector. In my case the proper alignment was achieved when the plastic "pin" was not touching either side of the notch on the adapter card and was sort of sitting in the middle with air gaps on both sides. Had to use a magnifier and a flashlight for that. This position is unstable, so you have to hold it in place wile tightening the screw. And don't try to realign it when fully inserted or you can bend the pins in the connector or strip contact pads on the card. Just pull it out and try to shove it back in until it lands with the pin right in the middle.

Hope this helps.

I'm glad it worked!  Those no-name M.2 adapters are real garbage
