Title: 2x Sapfire RX 4704Gb OC Hynix Post by: Zlobnui on October 29, 2017, 07:55:23 AM 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.

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 https://anorak.tech/t/anoraks-vbios-collection-optimized-settings-for-performance-power-saving/13 Title: Re: 2x Sapfire RX 4704Gb OC Hynix Post by: fapar on October 29, 2017, 10:11:28 AM Hi!

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) Title: Re: 2x Sapfire RX 4704Gb OC Hynix Post by: Zlobnui on October 29, 2017, 05:09:57 PM 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. Title: Re: 2x Sapfire RX 4704Gb OC Hynix Post by: Zlobnui on November 02, 2017, 04:08:17 PM I just install Blockchain drivers and all is become fine! 27-28 Mh/s from one card. ;)
