hey everyone and welcome back to another mining chamber video in
today's video we are going to go over your bio settings and everything you need to know
when it comes to your bios so let's go ahead and get into the video right after the intro
setting up the proper settings for your bios is an important part of building your mining rig
now most of the time if you have a mining dedicated motherboard you don't have to change any
settings everything is automatically set properly for you but in some scenarios you'll have to open
up your bios settings and troubleshoot from there if you're running into any issues that can lead to
your mining rig not running properly or some gpus not showing up on your mining software
now the first thing i want to mention is all the bios are not the same so you might have different
settings you might have different wording for your settings but ultimately the options will be
very very similar so if i go over something in this video and you don't have exactly the same
words just try to look for something similar to it and now let's say worst case scenario
you've accidentally put a wrong settings on your bios and then you can't post anymore
you can always do a cmos reset and that's basically resetting your bios to default
settings so this is something really good to know because it's usually the fix for a lot of problems
if your motherboard is just not posting at all and you're not getting any display and it's not a cpu
compatibility issues or any hardware issues then a cmos reset will most likely help you out to do a
cmos reset it's very simple all you need to do is you want to unplug your power supply from the wall
make sure there is no power coming to your rig at all and then from there you just want to take out
that little battery on your motherboard there is a little trigger next to it where you push it in and
then the battery will just pop out and after the battery pops out just put it to the side for now
and then you want to hold the power button while the rig is off for 30 to 60 seconds
i usually just hold it for 60 seconds to make sure that it successfully reseted your bios settings
and then after that you can go ahead and put the battery back in and then you can plug in
your power supply back into the wall now with having that done it basically reseted the memory
for your bios settings on the motherboard and then everything is back to stock so now that's
enough about the cmos reset now i hope you guys understand what it is and know when to use it
now we can go ahead and move on to the settings so the settings will be in three different parts
first you have the essential settings these are the ones that you definitely want to keep an
eye on and make sure you have them set properly the second ones will be optional settings that can
benefit you if you choose to use them and then we also have the usb booting settings and that's for
people that want to use a usb for their operating system whether it's ibos or any other mining
linux operating system and that section will be especially helpful if you're also planning on
running another hard drive with it or an ssd with a different operating system for example for your
personal computer so in this video i'm using my msi z270 gaming m5 motherboard as an example for
the bios settings now like i mentioned earlier you might have some different wordings and you
might have a fully different layout for your menu but don't worry it should be the same concept now
to get into your bios you want to figure out what's your bios hotkey you can find that in
your motherboard's manual or you can just look up your motherboard's name and then hotkey for bios
usually it's the delete or escape key so in my case it was the delete key and all you have to do
is the moment you turn on your rig start spamming your delete key just keep hitting on it until you
see that menu pop up and then once that menu pops up you're good to go there is also another menu
called the boot menu and if you get that boot menu instead of the bios menu you might find an option
there that says enter setup so just navigate to the enter setup and then you'll be good to go
so the first settings i want to look for is the pcie gen speed as well as the mining mode for my
motherboard and i was able to find those in the pcie subsystem settings so after i open
up my pcie subsystem settings you guys can see here i have the pcie graphics card max
link speed so this is where you select the gen speed for your graphic cards to be running on
now generally it's usually on auto but if you're planning on running more than two graphic cards
i would usually recommend setting it on gen 2 and that should work most of the time and if you
still have troubles if you're trying to run for example 13 cards you can try to set it on gen 1.
now the reason for the settings is because your graphic cards don't need to run on the full gen
speed they can run on a lower gen and they'll be completely fine for mining now i'm not sure if it
will affect your gaming performance but you can feel free to try it and then change it whenever
you want so here in this motherboard i have two places where i have to set them to gen 2.
you might have more than two places but just look around for any places that have auto and
gen 1 and gen 2 and 3 and then just change them to gen 2. there is also the pcie latency timer option
and usually you don't have to change that one at all having it as default is completely fine but
in some scenarios if you're having troubles with your gpus and for example when you're running your
mining software as soon as you make the dac file it starts crashing or acting weird then this is
one of the settings that you might want to go back to and try to change it ideally you can put it
up to 94 or higher and what that setting does is just controls how long each pcie device can hold
the bus before another one takes over so like i mentioned you don't need to focus on the settings
unless you're running into issues so just leave it as default for now and come back to it if it's the
last option you have and then after that setting you also have the mining mode or 4g decoding
sometimes they are two different options but in this scenario they're both together so mining mode
and 4g decoding needs to be on if you're planning on mining with more than just one gpu and even if
you're mining with just one gpu just turn them on it won't affect your motherboard or your gaming
performance in any bad way so just have that setting on and then you should be good to go
in some scenarios when you're booting your mining rig and you just see a pitch black screen and you
don't even see the bios it can sometimes be due to the 4g decoding to being turned off so in that
case you want to unplug all your gpus except one and then boot into your bios turn on 4g decoding
or mining mode and then plug in the rest of the gpus after you turn your rig off make sure when
you're unplugging and plugging off gpus your rig is completely off and handle everything with care
now the last essential settings is the one that deals with your display so usually you want your
display to come out of your motherboard rather than the gpus it makes everything a lot easier you
can just troubleshoot your gpus freely and unplug them and plug them back in without having to worry
about the display so not every motherboard and cpu has this capability you first need to make sure
you have integrated graphics and to do that you just want to look at your motherboard if you have
any display output such as hdmi or dvi then that means you most likely have integrated graphics
so the next step you want to do is you want to go through your bios settings and then you want
to find your graphics settings and set that to igd which also stands for integrated graphics now peg
stands for pcie graphics and that's for the gpus so it's better to just have that resource come out
of your motherboard and cpu rather than from your gpu and it's especially useful when you're trying
to bios mod and all that stuff as well so now that wraps it up for the essential settings and now we
can go ahead and move on to the optional settings the first setting we have in the optional settings
is the ac power so what this option does here is a good example for it let's say you live somewhere
where the power goes out very frequently so if the power goes out your mining rig will turn off
so having this option set as on or power on or last state based on what bios you're using what
it will do is the moment you get power again the rig will turn automatically right on so the moment
your motherboard gets power who will turn on without you having to turn it on manually now if
you decide to shut down your rig manually it won't turn on right away so you don't need to worry
about that but this can be pretty useful if you just want to plug your rig it turns on right away
and if you're worried of power loss and then you just want it to turn back on right away then this
is a good option to keep on one of the best tricks i found with this option was using smart plugs
especially if you're mining on hive os you can just have a smart plug connected to the rig and
then you can turn the rig off and on just through your phone by turning off the smart plug and then
turning it back on in a way it will resemble your electricity turning off and then it's turning back
on and that can be useful if your rig is stuck and on hive os it's showing offline then you can
just try to reboot it that way and then it might work completely fine so other than the ac power
there's other multiple options that people decide to turn off for example your audio controller on
your motherboard and what that does it just turns off the actual physical ports on your motherboard
and i don't know exactly why people do it i think it's to reduce the power usage but at the end
of the day it won't take that much you can feel free to turn off anything that's not being used
so for example your audio controllers all these additional usb ports and a bunch of these sata
ports as well but again i don't think it will make that much of a difference so you can feel free to
leave it on it's not a problem at all now in the optional settings there is also flashing your
motherboard's bios and usually you don't have to flash your motherboard's bios but if you do have
a really outdated motherboard bios or you did all the troubleshooting steps and you're still having
troubles then you can try to resort to flashing your motherboard's bios all you need to do is just
go to your motherboard support page find the latest bios put it on your usb stick and then
come to the bios and then choose the flashing utility if you need more information on that
every motherboard has a specific guide to it to do it on their manual so feel free to check that out
so now that wraps up the optional settings now we can talk about the usb booting settings so these
settings are only if you're planning on using a usb stick to boot into it so if you have hive
os flashed on a usb stick or any other mining operating system then you want to check out this
section of the video if not then you can feel free to skip to the outro now the first thing you want
to look for is the boot mode and in the boot mode you want to make sure you have legacy and uefi
set sometimes you'll have this differently for example you might have a completely different
option that will say legacy support or csm support and you just want to make sure you enable that
and in some scenarios you will also have an option that says usb boot support so you also want to
enable that as well and then after that you also have your boot order priority in your boot order
priority it's basically what your mining rig will look for when it's booting in so if you
put your first option as a usb stick for hive os your mining rig will always go to that one first
and if it doesn't find it it will go to the second option so this is very useful if you're doing dual
booting and you have windows ssd as well as a hive os on a usb stick so like that you can tell your
rig to boot into which one you want first and then from there you move forward this topic is heavily
documented on the internet if you have any further questions just look up your motherboard's model
and then the question you have and i'm sure you will find the answer so now that covers the bias
settings i hope you guys have now a better idea of what to do when you're in the bios and what
to change when you're in there as well so let's go ahead and wrap up the video the next video
that will be coming up will be which operating system should you be using which will be the
best next step from this video and if you haven't built your mining rig yet then i highly recommend
checking out the mining rig build guide which is the video that came out before this one the link
for it will be in the descriptions below now that wraps up the video thank you guys for watching
this video if you have any questions leave them in the comments below and i'm curious to know if you
had any settings that you needed to change to get your mining grid going please let me know in the
comments as well i'm sure there's a lot of things i could have covered but i just didn't come across
and if you like this video please leave a thumbs up and if you're not subscribed make sure to
subscribe this video is focused on the basics as well as the next one but i will be posting a lot
more entertaining content very soon so thank you guys again and i hope you have a wonderful day
