I've been mining with ccminer on my GTX 780 over the past 3 or 4 days. However, it has stopped working.
It's been working fine over the weekend, getting around 2000 khash/s. But now, all I get is this error:
GPU #0: result for nonce $00000000 does not validate on CPU!
For reference, here is my .bat:
ccminer35.exe --algo=x11 -o stratum+tcp://220.127.116.11:7903 -u [wallet]+0.001 -p 123 --quiet
I've tried with two different pools, and I get the same error on both. Neither the GPU or the CPU is overclocked.
Using minerd-corei7-avx instead of ccminer works, so there is nothing wrong with the pools. However I only get around 500 khash/s with cpu mining.. I'd rather use ccminer.
I'm also getting artifacts on the windows desktop sometimes when I try to start up ccminer, little green or white dots appear at times then disappears. And sometimes when I try to start up ccminer the screen blacks out and I get a "nvidia driver crashed and has been restored error".
I've been using MSI Afterburner while mining this whole time and set the fan speed to 100%, so temperatures have been low.
All was working fine yesterday... Did my graphics card break or something?
