Miner works 5-6 minutes, then crashes at the same settings with ewbf. Gtx 1080x8
This is most likely due to overclocking. You have to readjust it - zm puts a different load on your GPUs.
I completely removed the overclock from my cards, and i still get issues after a few seconds after launch, i think there is something else, and it's across 10 rigs so...
I was wondering how do you deal with intensity inside your miner ? to decide how hard you go on the GPU's ? maybe if you include custom setting per gpu we could find the sweet spot for any GPU depending on making & brand. You miner seems to push extremely hard the gpu's, and maybe "lower" tier ones even of the same model could need some tweakings even if they're not overclocked i dunno. For example i have EVGA's cards that work with your miner as stated in a post before that i consider to be higher tier than the other rigs that use KFA2's, they're both 1070 but the KFA's perform lower than the EVGA's but the rigs consume less power so it all balance out.
Concerning intensity: There is no such thing like intensity which I'm setting to make the GPUs run faster, if this is what you're thinking about. The performance depends mainly on how well you've designed your algorithm and how well the program that implements it is able to utilize the GPU.
If I understood you right, zm fails on cudaMemcpy on some of your rigs. Does a particular GPU fail or do they fail all at once?
