( edit ) The multimeter's probe head is too fat to reach down the back of the connector.

FYI, if you don't have needle tips for your probe leads, then a short croc-clipped test lead and a T-pin change the probing lead to a needle tip. Handy to get down into the backside of a leaded connector.

After a good month of behaving the same error has arisen ( same host ), again with only the gamma ray pulsar binary work on the GPU. For example :

.... which blew off 193 units before I caught the problem. Notably it started just after a reboot required for new/major flatpak updates ( but not the video drivers ) for the operating system. Another reboot has solved the problem ie. the units are completing rather than aborting after a few seconds and one has validated. Go figure !

Cheers, Mike.

( edit ) Actually I think that may imply that the process of updating, say, the ICD loader runtime (libOpenCL.so) could be the issue here. I now recall that I didn't shutdown BOINC before rebooting after the flatpak downloads, IIRC the update is not complete until after reboot. Subtle, see this diagram :
