In Hive OS, it always sets kernel 1 automatically
Make sure that -J 1 is not passed. The program should autotune, or you can set -J -1 to force autotune.
I tried kernels from 5 to 8 - they work poorly, very few shares are found.
On windows and cuda 11.5 kernel 5-8 gives the best results on RTX cards. The next version will have 16 kernels to try to improve the performance on low power.
You need to find out why your cards in the rig is using 168- 241 watt. Cards seems to trottle. (downclock and perform poorly) They need to run at the same wattage all the time. Did you manage to run them in p0 state?
v1.42 windows 11.5 build
Kernel 1 RTX 2060 31 MHASH
Kernel 8 RTX 2060 33.5MHASH (but needs more power)
v1.43 will be released in a few hours.
I use P0 , tbm 1.42 cuda 11.4 , on cuda 11.5 I have worse results . video cards do not throttle, core frequencies do not drop off, this is out of the question. raising the power does not give an increase in hashrate, ethereum mining does not need a high core value, it only uses memory.
