Hi and thank you for you words,
That happens to me too. I dont know why, but when you get a lot of GPU RX580 in one simple motherboard with differents settings, some times one of them drops the wattage. I think is not the VBIOS flash you are using, maybe that one needs some special adjustment (Try playing with low or high voltage). In my case, I put it on another worker with different settings and works fine.
Hi thx for the fast reply, I played with the wattage but every time I got the same issue the only thing that I have not do is to put it into an other worker thx for the advice 
.Take care of you bro cheers
hey sir, your rom not accept in my K4G80325FC model cards.
my orginal rom 264 kb, your custom rom 524 kb
could that be the reason?
thanks
that’s weird … I just looked for my original file and is 524.3 kb… maybe you have to use polaris edit bios with you own file, if you change you gonna get the same 264 kb…
Update 2: after an hour and half, started getting invalid shares again
Update: My core state was set to 1, changed to 3 and it’s been stable for more than an hour without invalid shares 
Hi @amackata, I got your bios and your overclock config on a PowerColor RedDragon with Samsung mem, my hashrate is looking good, but I’m getting 1 invalid share every 10 min or so, any tips? The card is at 53w (hiveos panel). Should I play with undervolt? Do you think I should try higher or lower volts?
Hi mespron,
Yeah ! depending your GPU. I can get a stable rig at 31.7 MH with not much invalid share but when I try to pass 32 MH I get more errors and invalid shares…
@dangerover do you have an msi armor card ? if yes share with me your stock bios if you have one it would be very nice from your part.
Happy mining
Hi @dangerover ,
Nop I don’t have. But share your original VBIOS with me and I try to make the modification.
Give me some info about your GPU (brand and serial model)
i not have a msi cards

thank you, now i uploaded your fixed mod on my card 1, but energy consumption 92w, your energy consumption is 60w, what could be the reason?
you have to enable aggressive undervolting in the oc settings
thanks for your answer, when I select the voltage drop it applies this selection to all cards, however I just installed a bios with mods on one card. I guess that’s why the cards are dropping.
yes you can’t apply it for only one card but it will affect all amd cards on the rig (nvidia card wan’t be affected)
i installed bios mod only on a card i guess i need to install vbios on all cards. thank you
Hi, @amackata would you help me? My card is: MSI Radeon RX 580 ARMOR OC 8GB GDDR5. RAM: Samsung K4G80325FC xxx-xxx-xxx My BIOS: BIOS Download
Hi @bill,
Ok. I think it’s the same VBIOS I shared before, but I do it again. You can download here: https://amackata.tk/download/Vbios/RadeonRX580-8G-Samsung_K4G80325FC-MOD.rar
Any way remember this, POLARIS BIOS EDITOR is really easy:
Thank you!
thank you very much
