Title: Tsiv's XMR Miner? Post by: Turbo2 on September 25, 2016, 02:41:43 PM Hey guys, is there anyway to limit the amount of GPU resources tsiv's (v0.17) ccminer uses?
I am getting a good hash rate from my 2GB GTX750 Ti, but since it is my main and only GPU, it is slowing down my Windows 7 too heavily to let it run 24/7. I've tried to use the bfactor and bsleep commands but they only help a little. If I could say, tell ccminer to only use only 80% of my max GPU power (or limit it via Windows), that would solve everything. Any ideas? :) Title: Re: Tsiv's XMR Miner?

If that doesn't work you can try lowering the launch config. For 750 Ti I think it's 8x40 by default. Title: Re: Tsiv's XMR Miner?

To what values for example? 8x40 is the default bfactor value, so I am not sure what "launch config" you are referring to? Regardless of how high or low I set those values, I was not able to get GPU usage below a constant 95% :-\ Title: Re: Tsiv's XMR Miner? Post by: bathrobehero on September 25, 2016, 08:38:25 PM Launch config is different from bfactor:
-l, --launch=CONFIG launch config for the Cryptonight kernel. a comma separated list of values in form of AxB where A is the number of threads to run in each thread block and B is the number of thread blocks to launch. If less values than devices in use are provided, the last value will be used for the remaining devices. If you don't need to vary the value between devices, you can just enter a single value and it will be used for all devices. (default: 8x40) Try something like -l 8x30 or -l 8x20 I guess? I don't know I haven't used launch configs for cryptonight, only for scrypt-based algos. Your hashrate will be reduced by a lot though. Title: Re: Tsiv's XMR Miner?

Title: Re: Tsiv's XMR Miner? Post by: antantti on September 25, 2016, 11:26:37 PM -l 8x60 used to give best hashing performance on W7 with 750ti, far from responsive computer though. Play with -l 2/4/6/8 x 20/25/30/35/40/45 to find what works for you.
If on W8, 8.1 or 10 8x60 crashes. |
