See thats what i dont understand, since getting everything secured and deleting all connectors that i can... and soldering the wires my riser issues have pretty much dissipated... most of the issues ive had in the past was from sag on the gpu's over time in the pcie slot and the pcie adapter coming loose from viberations... between clips i printed and hot glue... everything is running smooth as butter....
My "mining shelf/rack" doesn't have sag issues.
Vibration .... not sure yet, but the weight of the GPU helps hold it IN the slot and the slot does latch on one end - the MB end of the risers doesn't see much vibration.
Those clips look like an interesting idea to cure THAT issue, too bad I don't have a 3d printer.....
A small polish company produce the clip in volumes and is willing to ship overseas.
Do not buy myself but hear lots of positive feedback.
