Yes gold mining decreases every year. It is harder and harder to find gold now. Eventually we will asteroid mine it, but that won't be feasable or cost effective for decades.
I'm not sure that's true.
our calculations point towards gold production peaking at some point between 2022 and 2025
There have only been a few short periods in history where production has declined.

However, we are certainly approaching a period where gold extraction is going to sharply decrease irreversibly for the first time.
at current rates of extraction... known gold reserves worldwide would be depleted in about 17 years.
cant get it running get all time an cuda error at GPU 5 on 2 different rigs with 6x GTX 1070. tried over clock and non overclock same result.
CUDA error DRIVER: '2' in func 'bminer::cuckoo::CuckarooSolverCuda::Initialize' line 122
[FATA] [2019-01-22T21:10:50-05:00] Fatal cuda error in GPU 5. Terminate soon...
Raven mining runs super stable 8 days uptime.
any ideas
Windows 10 actual geforce driver 4 GB ram 24 GB virtal memory
Seems a bit low on RAM. I would try bumping virtual memory to 40-50GB, disconnecting half of the GPUs, and then re-adding them one at time.
Indeed, you're fighting the minimum ram requirements. If increasing the paging file size doesn't fix it, you could try switching to an older version of windows, switch to linux, or wait for them to reduce the ram requirements on the miner.
Nvidia 6GB cards and AMD 8GB cards supported. 6GB cards in Windows10 may not work as WIndows steals some of the memory.
