Title: one of the gpu has a low mh/s value Post by: Serdal on December 28, 2020, 07:35:25 PM friends, I have 5 rx 580 8 gb. 4 of them 29.5 mh / s but one of them 25 mh / s. why is this happening, can you help me. motherboard: asus strix h270f gaming Title: Re: one of the gpu has a low mh/s value Post by: smoolae on December 28, 2020, 09:44:49 PM friends, I have 5 rx 580 8 gb. 4 of them 29.5 mh / s but one of them 25 mh / s. why is this happening, can you help me. motherboard: asus strix h270f gaming Hi! Download GPU-Z and open it. There is a "Memory type" slot there where it shows what RAM your GPU uses. It might be that 4 of them are Samsung and the 1 is Elpida/Hynix/Micron. Also, download MSI Afterburner and take a look what is the memory/core clock on your GPUs.

I also adjusted the MSI afterburner settings. it was always 1 gpu less mh / s.

Ie where is the monitor plugged into. i view screen onboard vga Do all of the GPUs have the same memory type? How did you do the flashing, did you use right timings? What are the temperatures of the GPUs (are they different)? Have you tried to change the riser?

This doesn't sound like a raiser issue.With a faulty raiser, the hash rate would be much lower, or it would change over time. 25 mh / s is the default hashrate for this video card.

Have you tried to change the riser? and wmy rig working now 143mh/s but ethermine i see this rig dont work until 40 min. ethermine does it for the 4th time today. why is this happening all of gpu same memory type i flashed all of them same all of gpu tempurates 55-62 Title: Re: one of the gpu has a low mh/s value Post by: batsonxl on December 29, 2020, 07:46:10 PM What else programs are you using? amdmemtweak, overdriventool? tell all your system and progs you are running with?

That card can be more mining friendly if you don't overclock but instead downclock, if you have update the bios this is the only thing left to try
