Unfortunately I cannot help you with your problem. But I have one request for you. I think many users are interested in the performance of your quite expensive 6700 XT with gpuowl.

I need the software timings (iteration times in µs/it) for for the first 300000 iterations for a specific exponent.
I am currently creating a benchmark list in (.ods) format, which better reflects the performance for gppuowl than mersenne.ca which is better suited for CudaLucas You can use Linux or Windows-version, the values ​​should only differ by a few percent. The Linux version is around 5-10% faster. The windows version works without any further installation effort.

gpuowl -iters 300000 -prp 77936867

Fastest Windows Version (with Proofs) for most FFT sizes
