If you place config.json in same dirrectory with binary or specify path to this file via command line options, miner will update your config, try reduce threads to 32 or lower values.
Example:
"threads": [
{
"index": 0,
"threads": 32,
"blocks": 15,
"bfactor": 0,
"bsleep": 0
}
],
Please write back with threads count it start working, current auto-configuration too much aggressive, I know about it, will fix it soon.
Thank you.

The miner is now working fine with 32 threads and 15 blocks.
Thanks a lot!
Sorry if noob question here, but how exactly do I figure out the best threads/blocks configuration? It can't be like throwing random numbers there I hope.
Seriously, thanks a bunch for your prompt reply and your amazing work. Highly appreciate it.
from xmrig-nvidia.
threads and blocks can vary, important is 32 * 15 = 480, it number of hashed GPU done is one round, there also memory limiting factor 32 * 15 * 2 = 960 MB, looks like you card can't use more than 1 GB of memory for hashing. People with GTX 750 Ti reports same issue.
15 blocks it number of SMX cores (5 in your case) * 3.
So you can try 96x5 (threads/blocks) or 16x30 it should give average same hashrate and equal memory usage.

Thanks for the nice explanation.
A bit off topic, but does this miner also support the cryptonight-light algo?
from xmrig-nvidia.
At this moment no, will be added later.

I added cryptonight-light algo, single binary for both algos.

GTX 950M/960M - 32x15 crashes somehow it is too intense for this cards?
16x15 works but with a poor hashrate.
from xmrig-nvidia.
What exactly error? You can use numbers like 31, 30, ... for thread count, no need half it.

GPU #0: unspecified launch failure
cryptonight_extra_cpu_final line 247
Yes I tried 31,30,... But only around 16 seem to work with a hashrate of 70.
from xmrig-nvidia.
20x15 seems to be perfect for the GTX 950M.
25~26x15 crashes.
The same happens on xmr-stak-nvidia.
Not sure why this happens since the memory usage is below 85%. There should be another limitations at least on the mobile variants.

Not sure if related:
