I can now confirm that by making settings changes to the bios <advanced> <amd cbs> <zen common options><global c-state control> to "disabled" has ended my mysterious freezes/crashes on the ASUS Zenith Extreme motherboard with the threadripper 1950x that occured during seti@home project outages.

hi, u can now try to use the command line option to speed up your GPU app ;)

The command line depends on the exact model of AMD gpu that you have. The original discussion here was with a Vega 56. You appear to have a

MD AMD Radeon HD 7700/R7 250X/R9 255 series (Capeverde) (1024MB) driver: 1.4.1848 OpenCL: 1.2

Mike is still the best choice for getting advice.

If I have the right entry for this gpu, it is less powerful than the Vega 11 gpu. If that is true, then while you can improve it some. It is not going to get massively faster.

Let me look at my command lines for the Vega 11 and post it here. BRB.

-edit--

-sbs 256 -spike_fft_thresh 2048 -tune 1 2 1 16 -tune 2 2 1 16 -tt 1500 -period_iterations_num 1

You will probably have upto 3 mb_commandline_*,txt files in your seti@home directory under the "ProgramData" hidden windows directory. You will want to put the above in all three versions of the mb_commandline*.txt files.
The above is working for me. However, if your screen/mouse/keyboard response slows down too much (aka: laggy) then increase the "period_internations_num". I think the default is something like "20".

HTH,

mine is okay thanks for your answer ^^

my command line is

-no_cpu_lock -hp -high_perf -high_prec_timer -period_iterations_num 1 -tt 3400 -unroll 8 -sbs 512 -ffa_block 2048 -ffa_block_fetch 1024 -tune 1 64 4 1

with few lags and run well ;) but it don't take the ffa_block section, but all the fft pass are in 3 way ..

-tt 1800 is okay for BLC but not for Arecibo, i have to go up to -tt 3400 ;)
