I’d assume, all PCIe- Lanes, that are in behind of first bent position of a further PCIe-lane and/or behind a twisted PCIe-GND-PIN, where a pin is not in proper alignment, would cause all PCIe- lanes in behind to be switched off.Īnd/or maybe it’s just the PCIe-M.2 adapter and not the slot. Maybe if it’s not the CPU, your PCIe- slot has some pins are not in regular placement. Watching by, comparing with the other slot-pins helped, in which way they are regulary orientated. I never had achieved to bent any pins ofa slot this way, that would cause issues, the board gotten used on ebay had had that issue already.Īfter I carefully bent those pins back (sideway) to inner Position of the hole-side (directed to the inner slot), it solved the issue.
to the outside, but that was too much alredy. The bent pins were only bent max about a half to 1 millimeter max. This caused Memory problem, that pins not having contact to the DIMM’s pad when inswerted, causing RAM-modules in those DIMM slots not being detected. A few pins on two DIMM slots were a little bit bent (sideway) to the outside of the DIMM socket, allthough no DIMM inserted. Sometimes when such pin is bent a bit, it is directed more to the outer side of such hole to the outside wall of the slot, allthough it shouldn’t as long no card is inserted pushing it a bit to the outside.īecause I had a similar potentially problem with two DDR3-RAM-DIMM slots (similar system way as with PCie-slot with those holes and pins). When no card is inserted, those metallic brass- or gold-plated pins normally show within the tiny hole in direction to the card-slot from within the hole’s side. In that holes are the PCIe-slot-pins going through (on the upper) side of the pins, which are elastic and (sprung-loaded). 0.5-1mm little rectangular holes in regular distances from another. Or but first check PCIe slot mechanical issue: At both sides of the PCIe slot at the top-side you see many small max ca. If you’d have a spare CPU you could test if it’s not happening there. If the problematic PCIe slot, and its lanes came from CPU, maybe it’s the CPU (if the lanes on that slot, were really routed from the CPU.).
