hey everyone welcome back to another mining chamber video in today's video i'm going to show
you how to bios mod your rx 580 card i will be showing you two methods to do that and this will
help you if you're having around 22 to 26 mega hash on your polaris cards this will help you get
around 30 mega hash and this guide will work with any 400 or 500 series gpus so now let's get into
the guide right after the intro to bias mod your polaris cards you have two different methods that
you can use the first one is the temporary method and that is through using command line arguments
for changing your memory timings so that will be the first method that we will cover and that
method will be good if you're using it on your gaming pc and you don't want to permanently bios
mod your gpu you can just use this method and will work fine for you although the performance
won't be as good as using the second method and that second method being through the polaris
bias editor and that will be a permanent bios mod both of these methods are very simple to do
and they won't take that much time for the second method i'll show you how to do it on windows 10
as well as on hive os or any linux based mining operating system and then for the first method
you can follow the same instructions on windows 10 or any linux based mining operating system and it
will be completely fine so now let's go ahead and get started with the first method so here in this
rig i have one rx 580 plugged in and as you guys can see i already have some overclocks put in so i
have 11 30 for the core clock and then 850 for the core voltage and all these overclock settings can
be found on miningchamber.com i just did reduce the core clock just a little bit because this card
is not stable at 1150. so the first step you want to do is you want to go ahead and open up your
startminer bat file or if you guys have no idea how phoenix miner works then i recommend checking
out the video i've recently released on phoenix miner we talked about different command line
arguments and what they do so the two important commands that you want to keep in mind when you're
running your polaris cards are dash mt and as well as dash rx boost 20. so the rx boost 20 will help
you achieve a little bit more hash rate and then the dash mt this is basically bios modding your
card without having to actually bios mod them so when you run this miner it will only change the
memory timing temporarily and then when you turn it off it will go back to default so now one thing
that's very interesting is if you guys check in the radeon settings you'll notice here you also
have memory timings in the radeon settings and you have memory timing level one and level two and
in phoenix minor they have option number one in option number two so if you do option number one
or option two it will automatically change in your memory timings for your radeon settings so now
since the rx 580 that i have running has a high next memory type i will be running memory timings
number two because that worked better for me but before i go ahead and run the memory timings and
the rx boost i am just going to go ahead and get rid of both of these commands and run it without
the memory timings or the rx boost so you guys can see how much hash rate i'm currently getting
so as you guys can see here we are getting around 19 mega hash on phoenix miner this is just with
the overclocked so we don't have anything else in there and then what that's telling me is that
i definitely need to bios mod this gpu so i can have the full potential which is an additional
10 mega hash or 11 mega hash on this card so now i'm going to go ahead and close the miner and then
we can try it with the memory timings so what i need to do here is just add these back you have
memory timings 2 and then rx boost 20 and just save your file and always make sure you run your
miner as an administrator because if you don't run it as an administrator you won't be able to
change your memory timings or your rx boost and plus it will give you less issues along the way
so just make sure you run it as an administrator now before i also run it i want you guys to notice
the memory timings here on the right side for the radio and settings so as soon as i run my
miner it will change the timings right away as you can see here set vm timing to level 2
and then you can see on the right side for the radeon settings your memory timing level was set
to 2. so what that means is you guys don't need to put it from the command line arguments instead
you can do it from the memory timing level on the radio settings itself so now let's go ahead and
give the gpu some time to tune and then after tunes it should be around 28 to 29 mega hash
so now that it just finished tuning you guys can see here that it did find the best gt value so
this is the auto-tune value and it says 61 so what that means is now i can go ahead and close this
miner and then instead of have it auto-tune and take forever to do that i can just put here gt61
so now the next time i run phoenix miner with this gpu it will automatically run it on gt61
so now that it's right with the gt value it doesn't take forever to auto tune and it's
right away at 28 to 29 mega hash now with this method of modifying your bios i was not able
to get the car to 30 mega hash but with the other method that we will try which is the polaris bias
editor you should be able to get it to 30 mega hash this one is just a quick fix if you're for
example using this gpu on your main pc and you don't want to change your bias at all you can
just do this instead and you'll be fine with just 29 mega hash rather than 30. you can also try to
play around with the overclocks a little bit like i did here but it still didn't take me that far
just be careful when you're messing with the overclock settings for example when i had this
gpu run on 1150 core clock it was taking around 200 watts off of the wall with the entire system
and just the gpu was taking around 170 watts so you don't want to push the core clock too much
and when i put it back down to 11 30 it started taking only 170 watts off the wall for the entire
system and then for the gpu only it was 140 watts because the system takes around 30 watts idle
so changing the core clock too much will end up causing you to draw a lot way more power than you
should be drawing because your gpu is not going to be able to support it with just 850 under volt
because your gpu under volts will not be able to support the core clock you want to put in
it and also your memory type does play a role in this so if you have a different memory type like
samsung or micron then you might have different flexibility into your overclock settings or you
might be stricter on them so just keep that in mind as well so that is it for temporarily
modifying your bios now let's go ahead and get started with modifying your bios with polaris
bias editor so the first thing you need to do for this method is you have to install three different
applications that we're going to use the first one being amd vb flash and that's what's going
to flash the modded bios on your gpu and then the second thing you want to install is polaris
bios editor and that's what's going to modify your bios by just one click and it won't take
that much effort at all and then the last thing you need to install is tech powerup gpu-z you're
going to use this to save your original bios you can also use ati flash to save your original bios
but it will be easier through this way and then optionally there is also the patcher the patcher
is good if your card ends up giving you a code 43 after modding it and then you can just run
the patcher and then it will refresh the card and it will be all set so if you do get a quote 43
then come back to this video install the patcher from the descriptions below and then you'll be all
good to go so the links for all these applications will also be in the descriptions below so now once
you install all the three applications that i mentioned in this video you should have something
like this polaris bias editor tech powerup gpu-z and as well as the ati flash folder so the first
step in this process is go ahead and open up your tech power of gpu-z and once you have your tech
powerup gpu-z opened you guys will be able to find here your gpus so if you have one graphic
card plugged in you'll only see one here and i honestly do recommend doing it one at a time
unless you're doing it on hive os or a linux based mining operating system but if you're doing this
on a windows 10 system then do one gpu at a time so you don't mix between the different biases and
then you'll end up running into a lot more issues like that i will show you guys later on how to do
it in hive os it's much easier to just download the bios from there and modify them on your system
and then upload the bios back to hive os so now in windows 10 we're doing it here with just one
gpu like i mentioned and the first thing you want to do in gpu z is you want to go ahead and click
on this icon right here and what that does is save your bios on your system so just do save
to file and then you guys can pick wherever you want to save it so i've already saved this bios
on my system and as you guys can see here i've named it rx 580 hynix and 20 mega hash that's
because that's how much hash rate i'm getting on this gpu now for you if you bought these gpus new
you can put your serial number of this card here so you know which bios belongs to which card but
for me since i only have one card that i need to bios mod i don't need to worry about mixing the
bios or anything like that but if you have more than one gpu then make sure that you put something
that can be distinctive between every card you can even just put a number on the card itself with a
marker and then name the bios based on that number and also the memory type you guys can find your
memory type here so it says hynix gddr5 now that's the biggest difference between different cards so
if you have even the same rx 580s one might have a different memory type than the other and that
does impact your performance as well so just make sure that you save your bios and in this case i've
saved it into the ati flash folder you guys can save it wherever you want but to have the process
easier just put it in your ati flash folder for now until you finish the bios modding and then you
can take it out of there so after you have your bio saved the second thing you want to do is you
want to go ahead and open up polaris bias editor so go ahead and double left click on that it will
ask you if you want to copy something to clipboard just say no and then you'll get to this screen
right here and now you just need to go ahead and open the bios the one that you just saved so if i
go back to desktop and then the ati flash folder i'll find my bios right there and then just open
that into the polaris bias editor you guys will see multiple different things here you don't need
to worry about any of this all you need to do in this screen is just click on one click timing
patch and then just hit yes on whatever it shows you and after that it will automatically apply the
patches for you so as it says here hynix memory found at index number two now applying universal
hynix mining timings and then after that your bios is modded and that's all you need to do so
now the third step would just be saving your bios mod and then you can just rename the one that you
currently have saved the stock bios just add the mod to it at the end you can name it whatever you
want but just like i said make sure that you know which bias belongs to which card and always make
sure that you keep the original bios if anything happens wrong or if you ever want to sell your
card or give it to someone you can just flash that original bios back onto the card so now let's go
ahead and save that modded bios and then after we save it we can go ahead and close the polaris bias
editor and now the fourth step which is the last step you just want to go ahead and open up command
prompt as an administrator so run a command prompt as an administrator and then after you do that
go to your ati flash folder and then just right click on the amdvb flash.exe go to properties and
then copy the location for that file so now after you copy the location to your amdvb flash go back
to your command prompt and type in cd which is change directory and then paste in the path that
you just copied so now if i hit enter it will take me to that path where i have ati flash and
then all the flashing tools as well as the bios in there now that i'm in the ati flash folder all you
need to do is type out amd vb flash and then dash i and that will show you your gpu that's plugged
in so here it shows that on adapter number zero i have a polaris card plugged in and then the rom
size as well as the test test so if everything for you looks normal here then you're good your gpu is
plugged in and everything's showing properly and you know that your card is on index number zero
and now you want to refer to that index by saying amd vb flash dash p which is for flashing and then
you select the index which is zero and then after that you select the rom file that you want to
flash on your card so in our case we have the rx 580 hynix 20 mega hash mod so what i need to do is
type out rx and then you guys can hit tab and it will automatically autofill so whatever name you
have in it will just autofill the closest thing to what you typed out but you can also just type it
out fully without hitting tab so i can just say 580 hynix and then the 20 mega hash and all the
rest of the title so after typing out your bios file or hitting tab to autofill you can just go
ahead and hit enter and then after that you guys will see here it will flash the card and it will
say it's successful and then it will ask you to restart your computer and just make sure that
when you're doing this step that you're actually flashing the modded bios so if you do the stock
rom instead of the modded rom then you won't see any difference so just make sure that you do flash
the proper bios onto your gpu the one that's modded to avoid any mistakes you can feel free
to move the stock bios into a different folder and then you can just keep the modded bios in here so
just make sure that you have it flashed and then after that when you see the restart system to
complete the bios update then you know that you've done it successfully so now i'm going to go ahead
and restart the system and then we can see how much hashtag we're going to get with the modded
bios so now i went ahead and restarted the rig and the bios mod is complete so what that means is i
can go ahead and run phoenix miner or any mining software without putting any parameters and then
i should be getting around 30 mega hash instead of 20 megahertz so if i go ahead and edit my phoenix
miner bat you guys can see here all i have is just dash rx boost 20. this is recommended to
have whether you buy a smart your card or not so now before i run my phoenix miner scripts
i first need to set my overclocks again because after bios modding your card your overclocks will
reset so as you guys can see here the voltage is at all the way at 11 50 and the memory is not set
properly and what i did is i saved the profile for my overclocks from before so i'm just going
to go ahead and load my overclocks and then from there it's all ready so you guys can save your
profile as well just by hitting save for file and then after that you can just load them every time
without having to change every value by itself so now like i mentioned before this card was
having troubles at 11 50 core clock so i'm going to do 11 30 core clock that doesn't mean it will
apply for your scenario as well you can try 1150 and if you're drawing way too much power then you
can try 1130 instead and then my memory clock is at 2150 so it's the exact same overclocks that i
had running with the memory timings and now i can go ahead and apply changes and go back to
my phoenix miner and run my phoenix miner as an administrator so now let's go ahead and
give it some time so that it tunes up and then it shows us how much hash rate we should be getting
so as you guys can see here we're getting around 31 mega hash from phoenix miner with the bios mod
so it's a lot better than we first started which was around 20 mega hash so that is basically free
10 mega hash that you can get with your polaris card without having to do much work and no bios
modding does not hurt your card it won't kill your card at all actually the power draw is basically
the same as we started and if you guys want to learn more about bias modding or overclocking in
general there's different gpu overview articles that we have on miningchamber.com as well as a
full video that i've done about overclocking and bios modding and how they affect your gpu
and just remember you can use the same exact steps for your polaris cards whether you have rx 480 470
or 570s and you're most likely also going to be able to use this on the 590s but the overclocks
might differ slightly so if you want to run the overclocks try to just tune down the settings a
little bit and see if it works with you eventually i will be able to have all the overclocks on
miningchamber.com so you guys can just bookmark the website then you'll find different settings
coming out very frequently in the mining chamber articles now tobias mod your gpus on hive os
you could do it much easier so what you need to do is you can just have your rig running for
example here i have four different rx 580s and then you guys can see three of them are modded
and then the third one does not need modding is just a riser is kind of busted so i might need
to fix that and then it should be running fine now to mod your gpus in hiveos you first want to
access the cards list here now after you access your cards list i'm going to go ahead and select
the rx 580s so i only get the rx 580s here and then you guys now can see all the different rx
580s i have in different mining rigs so all you need to do when you get to this page you just
need to go ahead and download the v bios so that's your gpu bios and then after you download it you
can save this bios on your hive os storage which i recommend doing so you can have a backup there
and then you can also download it to your system so after you download it to your system you can
follow the exact same steps whether it's on your personal computer or anywhere that you want to do
it and then just run this bios through the polaris bias editor and everything like that and then you
can go ahead to your v bios rom storage and then you can do add bios and you can choose the file
that you modded and upload that modded bios to your hiveos account and after that you can just
go back to your cards and then from your cards to select vbios and then select the modded bios
so as you guys can see here i only have the 5700 xt gigabyte mod bios but in your case you'll have
multiple different ones for the rx 580s and then you'll also have your original bios for
every card saved to your v bios from storage now the benefits of doing it that way is you
don't have to do it one card at a time instead you can just download the bios of every card
on your hiveos account and then from there you can just modify them one by one again just make sure
that you save the original bios and save it in a way that's distinctive between every card so you
know which card belongs to which at least even mention the memory type on the cards so here i
have all samsung memory types so just keep that in mind and then hopefully you should be good to
go with hive os so that will be it for the video guys i hope this video helped you out and you're
able to get an additional 10 mega hash on your gpus if you have any questions or any feedback
