With 825 core voltage it might crash when you set the core clocm to 1145.
you got nice cards there. 71 watts , dont touch the settings anymore. you mine ETC i presume.
Yes, ETC
Hello
I appreciate all of your responses.
Indeed, it had no VDDCI set
so it marked errors.
I have 2 days with this modification and it gives me 1 or maximum two invalid shares a day, it decreased a lot.
Willdoicu you don’t have VDDCI configured?
My vddci is 800. Remove your dpm states. I got some invalid shares after hours of work due to wrong straps flashed with bios mode but i fixed it after flashing the correct ones and OC woth correct settings.
No, I do not
Samsung ram & one click Polaris flash don’t work that well with each other, try AMD tweak & stock bios…
Hello friend, I am in hiveos.
can be used?
you mean the REF setting and stock bios ?
Yes REF setting between 20 & 30 with stock bios…
well i did 29.29 MHs with REF 200 
and stock bios. i used REF 20 and 30 but got only 29 MHs. With bios mod i do 30.82 now with REF 20 or 30. My GPU is bad but still there is a difference.
That’s great… , what bios mod software did you use…?
polaris bios editor. you should download the original bios, then open it with polaris bios editor and hit the one click timings fix and save it with different name. keep the original file just in case.
flash the modded bios back and OC.
Well, I have that dual rx 580 asus samsung memory that usually gives problems, in one day its invalid shares shoot, others only 2 or 3 and other days none.
The latter I think happen less often.
It is strange because the same oc and bios mod I use it with another 2 rx 580 and they do not mark any error, they are perfect.
The problem is that even if they have the original bios it marks a few invalid.
I begin to suspect that the problem could be in the change of thermal paste or the pads.
Any ideas?
invalid shares are due to bad OC or bios mod. so check the bios mod you made or the OC settings you used.
With biosmod it reaches 31 mhs. but it becomes unstable with or without OC.
Right now I tried the factory bio. So far it does not mark me error or invalid but it gives me 25 and 27.8 with mod.
I do the biosmod with polaris one click.
any solution that you recommend?
Bios mod it with polaris and then start with coservative OC something like 1100 core clock 875 core voltage and 2000 mem clock. If its stable raise with small steps the mem and then the core clock.
Gracias, lo intentaré.
