No worries, Do you want to run a gpu benchmark, I can authenticate my steam account if you send me the QR code. we just need to coordinate at time. In most cases pci3 is sufficient. this one being TI overclocked could be a bottleneck. Im in sydney time and 8am till 12pm.

The thing that can catch us out is the riser cable. I have had this issue with the BBC running a 4060, At first everything was ok and then it started to glitch out. Main issue with riser cables is that they allow interference on high speed data transfer witch then causes crashes and nasty lag, The way we validated this was to put the GPU in a separate computer, everything worked, then added the riser card and boom. The Riser card should be 4.0 standard, I have checked Azzar site but it doesn't spec either. I have had PC's run on 3.0 standard before but it may have been under favorable conditions. I can't really see the large screen diagnostics you posted.

When you have a gaming laptop do you move it around a lot. Why are you not a fan of what you have at the moment?

That is a very interesting topic, what would really cause people to consider ARM for gaming is when they can cut 256+ arm cores onto a single chip. just raw threading capability or at the least create a bridge capable of joining multiple chips/ram units into a cluster that appears as a single machine like servers host multiple cpu's

There is no way for the GPU to detect that the power supply is inadequate at startup, there is no communication between them. The way they monitor this is to test that both cables are plugged into the sockets provided when we used to have 2 sockets on GPU instead of the new connector. This could indicate a cable has not seated correctly or shaken out of contact during flight. You may not believe it but I have seen first hand parts unplug after a long flight. However at this point I am guessing you have tried to reseat the cables for GPU. One thing that could be happening in a power supply is that 2 sockets are bonded together and then another 2 sockets are bonded together on a separate circuit, its far fetched but you could try moving the one of the gpu cables across to a spare gpu socket.
