my config for 2080ti is below:

[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_rtx_31”
[mining.miner_plugin_config.parameters]
device = 0
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024

also I only have 4Gb of ram in machine but 2080ti has 11GB not sure if system ram has anything to do with this.

This issue is sparkpool uses a differnt ports for different algos.
port 6666 - c29
port 6667 - c31
Hope this helps someone in future.
