[Music] what's going on everyone welcome Rabid here and today we're going to be building the most
powerful CPU mining rig on the planet well you know maybe it's not anymore three or four years
ago it might have been this is a beast but there are some thread rippers there's some new epics
out that are 96 cores so they're crazy the thread rippers do have higher base clock speeds so those
are a little better with the same amount of cores but this thing is going to be a beast so what we
got here is the Epic 7742 this does have 64 cores 128 threads and 256 megabytes of L3 cache which
means we can fully utilize this CPU on pretty much every algorithm for CPU mining minus Haven because
that one does need four megabytes per thread so we're only going to be able to use about half of
this but you know no one really Minds that coin on a CPU anyway but you never know anyway moving
forward let's kind of look at some parts here so I got eight sticks around because the epics
actually do support eight channel memory unlike consumer grade where you're only running dual
Channel memory so that's pretty insane to think of uh Rhonda Max for example it does have like a
limit based on each channel so opening up even more channels will allow for more hash rate so
that's crazy for thermal paste here I actually got this in here this is from Mod my mods I'll have a
link down in the description they sent this out to me for you know a while ago and I haven't had
a chance to try it but it looks pretty sweet here we'll see if this thing will keep this thing cool
so this will be a good test for this thermal paste so again mod my mods sent this one out to me so
we'll see if it actually works or not and kind of review that out in here for a cooler I did get the
4u cooler so this is a 4u cooler here what that means is its height will take up four slots and
like a server rack you can get them down to three to you I'm not sure if there's a one you but the
bigger they are the quieter they are this has a larger fan with a lower RPM so it won't be as loud
if you go down to like a 2u scale it's that's more like you know your Jazz miners actually that'd be
a one U and it has a slower fan but very very fast spinner to keep it cool so you can put that in a
small platform type of thing in a small server rack but the fan will be very loud not really
recommended for them home miners out there but yeah so that's what we got going on here the
CPU is pre-installed if you were to install this you know you got your own motherboard separately
as well as that the epics actually need a torque wrench and you got to torque it to the right specs
in the proper order almost like changing a tire here you know maybe a lot of you guys skip the
torquing part but there is torque specs there and you're going to want to add the proper torque so
it is pre-installed everything was tested so everything should work in theory once we get
this going so if you know if I fry something it's on me and I failed but let's get this thing built
and take a look at it okay so let's just kind of have a look I did sit this down on a bunch
of 3D printed little stands here I don't have the upright stands printed for this yet but I
will get that done once I decide where to put it when I'm done on my testing so I got some time to
get that ready but look at this motherboard it's looking pretty much brand new it's definitely in
good condition now I don't know what the torque specs really are on this but it's looking all
right I'm not even sure where to put the thermal paste when it comes down to that point now I think
there's a line of something going on in here and then there's a set of chips in each corner here so
I might have to do like a line in the middle and then a DOT on each side again I'm not 100 sure
I'm gonna do this AMD I think recommends an X for their thread Rippers and stuff so maybe I'll try
that but you know we'll worry about it when we get to that point but look at all the slots for
the round that is crazy we got our M2 slot right here I do have mine already I ordered it up it's
here I flashed and Hive a couple days ago it's ready to go I just got to get this thing booted
up but I wish all motherboards were like this so look we put the M2 in here and then we simply
instead of having a screw you just set that on top like so and then simply put that back in so
bam you know nice and easy that'll lock it in instead of having a small screw to mess around
with but yeah so far everything's looking pretty good on this motherboard so I'm pretty pumped for
this as for the ram I am going to be using this is Samsung Ram I'm not sure the latency on it lower
latency is best for coins like random X where other coins it doesn't really matter and I'm going
to be testing out single sticks versus two sticks versus four versus eight and get down to you know
what the numbers look like in some later videos but we got Samsung memory this is 266 megahertz
Ram ddr4 now you can get 3200 megahertz but that does cost a lot more so you know it all depends on
what your your bank account kind of looks like for this point so I went with a little cheaper here
but it should still be pretty good for what we're going to be using it for and size as well does not
matter these are 16 gigabytes per stick I think about 128 gigabytes total but when it comes to CPU
mining the size that doesn't matter you can get the smallest amount that you can find but if you
start to do like server operations obviously maybe proof of useful work who knows you're going to
really want to ramp up your RAM and get as much as you possibly can alright so I'm going to get this
RAM installed but I did want to point something out when it comes to these epics and stuff in a
simple way to kind of know where to put your RAM end in the slots as we know with ddr4 we do have
a longer side and a shorter side ddr5 on the newer stuff it's pretty close to the middle but it is a
couple pins longer on one side regardless the easy way to kind of point out how epic Ram goes is this
label here with the sticker and on the back side you can see the chips and stuff but this label
here will always face the CPU itself so as we can see here we're going to put the back side here
this will fit in this slot right here if I can kind of get this one hand it's not really going
okay that sucks there we go there we go all right I fail I'm failing okay anyway you can
kind of see it lines up this way and if we went to do that over here it won't line up so we'd
actually have to flip it making that label always face towards the CPU so that's the easy way to
kind of get it here label towards the brain all right so we loaded it up with ram everything is
installed looking good clicked in nice now one of the scariest times of ever putting things together
with a CPU rig is installing that Ram because a lot of the boards are really flimsy and flexible
and they almost feel like they're going to break but this is a super micro motherboard here and it
was very very firm and stiff so I didn't have any issues installing that Ram nothing was concerning
me at all about any type of bending so that's pretty sweet here another thing with super micro
um I don't think we're gonna have like CPU voltage control and stuff so this is probably only going
to be running at stock which is normal for epics anyway and I believe the Boost clocks only work if
you're not using the full CPU and we're going to be mining with this so we're going to be all core
all the time 100 percent so we're not going to have any overclocking capability so it's all based
on the clock uh the base clock speed of these CPUs also there is no battery you know I will pull one
out of maybe my test bench or something and throw it into here if we have to do any bios setting
changes we only need the battery to save changes if we're running everything default we might just
be fine without any type of battery but again you know we'll get over that hurdle once we get to it
and check out the BIOS and crazy stuff like that but yeah Ram is now installed we're going to get
to the thermal paste and get this cooler installed all right so it's coming down to thermal paste
time and I do want to point something out with this mod my mod stuff here it has a nice plug
here that all you got to do is simply unscrew like that and when you're done screw it back in
and then you just put in your little ordilio here for the actual nozzle so we're going to screw that
in and that's like that so that's pretty sweet at the bottom they also have like these condom
things looking happening down there so that's pretty crazy but I went over the AMD stuff and
on the website they had a video for their epics is they like to put an X and then like a little
dot on each corner here so I guess I'm just going to follow that and we'll see what happens if it
overheats we got to pull off the cooler and try something else and now the focus is kind of being
all messed up so let's just kind of do this and see what it looks like so let's get this thermal
paste in here pushing it down hopefully I got enough in here we should just quite a bit here
so we oh there it's coming out so here we go doing a big fat ax wow this CPU is so huge
yeah my uh thermal paste skills kind of suck that's not really the straightest
X I've ever done so now we're gonna do one here hopefully I'm not using too much
that seems like it's a lot but they also say you know you need a lot of thermal paste to cover
these so then we're going to put like a DOT here dot in here we're going to need a little bigger
dot in here and something like that over there so hopefully hopefully this works this is kind of a
pretty bad hack job and I use half the I pretty much used it all wow okay that sucks but how much
did I have here so it's actually one millimeter I think I had about 0.8 so I probably used like 0.6
millimeters worth of the thermal paste on this thing so this thing is a thermal paste hog so
now we gotta dip into our cooler and this is going to be interesting because it also said you need a
torque wrench for this but I don't actually have one all right so now for our cooler it does only
go on one way if we actually look at the bottom of this we can see that there are four holes here
obviously but these two are wider than these two and if we look at our motherboard we can see that
these two are at the far end and these two are actually in a bit so there is only one way that
this cooler will actually fit and it looks like the back side of the heat sink so the fan will be
facing to the wide side so we're gonna have the fan blowing out that way or at least situated
over here with the back of the heatsink right here so that's how we're going to have to put
this thing on okay so I'm gonna slowly put this thing in here and line it up something like this
looks like we got the holes all lined up here yes it's looking like it so now I'm going to
need a screwdriver you can't really see what I got going on here now so I'm going to move my camera
up and we can see we got things kind of lined up there but I'm gonna need to take my screwdriver
here and slowly Buckle it down and I'm going to start here then go to the opposite side here and
then over here and kind of go in that star type of order because we want a nice even push downwards
all right so I do have this installed and my torque specs are unknown so I guess we'll see
what happens it's pretty tight I just really really loose all the way till it pretty much
stopped and you know that's that so that's what I went with and now I did put it into fan one I
went all around the motherboard checked the manual online there's nothing that's labeled CPU fan so I
just went there and extended this over to Fan one and hopefully that will work for the CPU fan I'm
sure anyone will work we can just set manually in the by us how you want it to run and so on
but I am going with fan one here if I'm wrong let me know down in the comment section so I also got
the M2 installed right here as we can see it was very simple with that little plastic thing I wish
every motherboard had that that is awesome now there's jumper cables here to enable VGA and all
that that might just be onboard VGA detection this right here but we'll see what happens we
see there's jumpers for all sorts of things to enable disable and so on so that might bypass
bios control and doing it through jumpers again I don't know I'm new at this style server stuff
so about to play with it again no battery but now I'm going to install the power supply here so we
need our 24 pin we're gonna need eight pins here also going to need a four pin I believe this four
pin here Powers other components so it may not a hundred percent be necessary I am going to plug
them both in just to see what happens hopefully nothing blows up but uh yeah so we're gonna get
24 8 Pin and then a four pin here so I'm going to use my Corsair 1000 watt that's hanging out
on my test pack inch there because well I haven't used my test bench for quite some time so I'm not
going to need it for a while but hopefully we will be able to need it soon because we need gpus to
pick up again but for now you know we're dealing with this CPU so I'm going to plug this in get
the ethernet plugged in and I'm just going to see if this thing will automatically detect And Hive
OS all by itself all right so here we go I got the 24 pin right there the cpu8 pin is right here then
the second eight pin for the CPU is split into four and that is right here ethernet is plugged
in there's two other ethernet plugs as well to go into here I'm using the big one here we'll
see what happens and I got my power switch set up to the far end hopefully I think I'm at the right
pins maybe I gotta switch it around I don't think it'll matter and we're all plugged in so I'm going
to turn on the power to the power supply so far nothing happened oh that's spinning I see some
stuff happening there oh it automatically turned on I didn't need the power switch unless it was
pushed down from the weight here so I see green lights there I'm seeing a 104 Watts there 75 is
going from 73 to 104. the fan is seemed yeah the fan is spinning in there green light everything's
looking good so now let's see if it detects in Hive os I'll play with the BIOS stuff later but I
don't see if this thing is going to show up right off the get-go all right so it does look like we
are detected in Hive OS we can see the motherboard here the h11ssl-i super micro rev 2.1 here uh CPU
is 128 thread it's an epic 7742 64 core processor AES and then my I got the SSD in here because I
couldn't actually get my M2 to detect I think I have an incapable cheap little M2 that wouldn't
work with this you know same thing happens with three and 5000 series a lot of those m2s weren't
actually compatible with the 7000 series so I'll look into it but right now an SSD works just fine
especially just for some Hive OS action here but yeah things are looking pretty good we're detected
within Hive OS okay so we are all detected in Highway West and it I went through a couple issues
trying to get it detected and we're going to kind of run through some things right now and I've been
learning quite a bit since I've had some Hands-On with this and I thank everybody in Discord that
has been helping me out as well you know you guys are used to server stuff and stuff remember I'm
not an I.T person I'm just a minor and this stuff is new to me so it's fun to play with but yeah
let's kind of go through some things here first you can see the M2 drive it's not there I don't
think the one I actually had was compatible with this motherboard so maybe I'll look into
another one I did take the SSD drive out of my test bench that's working just fine here I'll
probably just leave it with this one but here you can see there's three ethernet cables here
or at least plugs here not cable so a originally I had it plugged into this one right here and it
wasn't detecting anything I was like what's going on it's given a lot of time to boot going through
all sorts of things nothing's working that's when I was playing with my M2 the SSD nothing would
work then finally I had the SSD on I just pulled this out put it into this one and then all of a
sudden bam it was in Hive OS so I was like okay so I went back tried the M2 you know backboard that
didn't work end result M2 is no longer in there because it doesn't work with this motherboard
at least the one that I have so I got the SSD on there so this one here is actually full ethernet
and ethernet only and this one here is actually ethernet and that I am IBM imbm Pi ipbi IP you
know something ipmi so this has ethernet and ipmi and ipmi actually is like a user interface like
you would connect to your Asics and stuff so this one here is ethernet and that ipmi and this one
is ipmi only so I can actually run normal ethernet you can run another cable here just for a kind of
logging in into this on its totally separate thing but again this one here runs both so I
got it plugged into that instead of using more ethernet cables it's kind of doing the same thing
so that's pretty cool we have a nice graphical interface within that interface is also where
your fan control and stuff is as well which is very interesting now again this board I am waiting
for to hear back from the seller to see you know if we can tweak out the memory and stuff as far as
I know super micro cannot change voltage as well as CPU clocks so it's currently running at 2.1
when it should be about 2.23 and it's doing about 1.1 volts when I kind of want to bring that down
to one see if I can go any lower so but we'll see what happens once we can figure out some tweaking
I got a lot of coin testing to do in the future with multiple sticks of ram less RAM and so on
but you know I've been learning a lot about this thing and these epics you know they got a lot of
features other than you know massive horsepower under the hood so I was just talking about that
dashboard and here you can kind of see uh what it looks like so I'm just in the the sensor readings
right we see our CPU temp is 71 our system temp is 63 our peripheral temp is 46 and so on voltages
and stuff now it this might this isn't actually that warm this is pretty good temperatures on 71
I believe in all core in the 7742s high loads sits around 80 to 85 degrees in a lot of the testing so
you know being in the low 70s is pretty good not to mention that right now it's like 34 degrees
down in my basement right now as an ambient so it's also hot as an ambient temperature for
coolness so I think we're doing pretty good on the temperature case uh but we go into configuration
we see we got alerts date time all sorts of stuff here we can go into fan mode and this is how you
actually it's a pretty simple interface here but I just set fan to full speed click it save good
to go and this is what I was waiting for and this is what a lot of people in Discord were helping me
get into because I was running to a lot of issues where the passwords weren't working and all sorts
of stuff so we actually had to do some magical Linux work and get this thing you know defaulted
to a new user and everything so you know thank you everyone again for helping me do that because you
know uh it wasn't easy for me you know for you guys it seemed like something very simple but
again I'm not an I.T anyway guys so the Epic 7742 is live I appreciate everyone checking
out this video I will see you all in the next one we got a lot of testing coming up Rabid Out
thank you [Music]
