locate your nvidia config file inside you XMR STACK folder and open it . You'll see something like this
"gpu_threads_conf" :
[
// gpu: GeForce GT 750M architecture: 30
// memory: 1694/2048 MiB
// smx: 2
{ "index" : 0,
"threads" : 64, "blocks" : 6,
"bfactor" : 6, "bsleep" : 25,
"affine_to_cpu" : false, "sync_mode" : 3,
},
],
Reduce the # of threads by 50% for example 128 = 64, increase your bfactor to 8 if it isn't already. Save and restart the miner, let me know if you still have issues.
If that didn't help you and you keep having issues, increase "bfactor" to 8, "bsleep" can be increased to help as well.
Also, you need to adjust the "threads" and "blocks" to get optimum performance from your card. (Adjust, settings, save, run miner and check hashrate after a minute, then shut it down and adjust again, etc.)
You can also right click on the Start button and open a command prompt (shell?), cd <path to your mining software>, then xmr-stak --help. This will give you all the commands you can use to start xmr-stak in a .bat file.
Thank you, @guidedcrypto bro and @ghostferret bro problem solved...
Happy to hear you got it resolved.
Keep on mining brother!
