Hi! Can you help me? After few time mining i have problem, that mining reconnect and my hash falling from 28 to 24-25 Mh/s. Se my screens. And i add bios.

And what about your cpu / ram / PSU ?
If they are both ok, this is probably too high timings or to aggressive clocks for your GPU's. Or a temperature issue. You should try to restore default clocks and stock bios and try it, after that changing everything step by step. also you could find some bioses here

Hello!
It's unclear why the DAG file was generated a second time
After that, there was a drop in speed.

What timings and frequencies do you use?
Try these:
777000000000000022C39C00AC595A3D90550F12B84C8408004006007E0514206A8900A00200312 0100F292F94273116 // 1167(cclock)/1980-2070(mclock)
or
999000000000000022C39C00AC595A3D90550F123CCF530C004006007E0514206A8900A00200312 0100F292F94273116 // 1167(cclock)/2050-2150(mclock)
or
777000000000000022339D00AC595A3D90550F1230CB440900600600740114206A8900A00200312 0150F292F94273116 // 1167(cclock)/1880-2040(mclock)

I use this timings:
777000000000000022C39C00AC595A3D90550F12B84C8408004006007E0514206A8900A00200312 0100F292F94273116 // 1216/2000

Unfortunately i dont know what timings were in stock. I bought cards not in shop. They were already overcklocked. I tried modifie bios and got much bad results. Around 20-23 Mh/s/

Yes, this happens after the DAG file is generated. And it can be and vice versa, first 24-25 Mh / s and when generating a new DAG file, again, 28 MH / s. Gpu not hungs. Clocks are the same. Different only power consumation. On 24 Mh/s it is less.

I just install Blockchain drivers and all is become fine! 27-28 Mh/s from one card.
