Not the driver but hardware failure.

are we really sure this is a hardware failure?

after updating to this driver i get tasks stuck trying to upload over and over again.

i noticed that they were using old and new driver so i assumed that was why it failed and aborted the tasks.

but now i also get new ones only run on the new driver to fail.

in case this is relevant: i did do a hardware change because i now have two gpus in one machine. i dont think that can be the problem because they get enough power and keep cool.

edit: there's a 527.37 now. i will try that and report back if it fixes things

updating to 527.37 did not solve the problem.

genefer tasks still get stuck at 0.06 MB upload.

pps uploaded just fine
