How to tune miniZ performance at low power? (--f11, for 144,5 only)[Deprecated]

This option is no longer useful. We keep the FAQ in case someone is using older miniZ versions.


miniZ includes a command line argument for improving performance at lower power values. When you’re adjusting your power and OC setting values you can play around with the optimization option --f11. This is only useful for Equihash 144,5 algo.

You can set it to levels [0-2], however 0 and 1 are the interesting ones. --f11=1 is the default value and the best for stock settings.

Usually, at low power --f11=0 produces better efficiency.

For the 1070 Ti  (PL = 90 W, core clk = +230, mem clock = -250) we get:

With --f11=2:
[ 0d 0h24m51s|17:21:32] 0>GTX 1070 Ti ` 100% [52°C/45%]*26.05 I/s 52.3(52.3)Sol/s 89( 88.4)W

With --f11=1:
[ 0d 0h24m52s|16:14:24] 0>GTX 1070 Ti ` 100% [53°C/45%] 25.38 I/s 51.1(50.7)Sol/s 91( 89.2)W

With --f11=0:
[ 0d 0h24m52s|16:40:05] 0>GTX 1070 Ti ` 100% [52°C/45%] 26.19 I/s 53.0(52.3)Sol/s 91( 89.5)W

As you can see, in this case there is a significant performance improvement by setting --f11=0. You should check this for your own settings and GPUs.
