lioness tech tips is over 10 years old
now so
it's easy for us to forget that many
viewers
may be encountering the world of pc
building for the first time
and while there's lots of great pc
building tutorials out there
there are also some that verge on
misinformation
so in this video we are going back to
basics
with episode two of how to basics
installing a cpu
[Applause]
[Music]
ugh
the hex gears impulse mechanical
keyboard comes with rgb lighting
and ip56 water resistance so in the
event that you do spill on your keyboard
you shouldn't even need to interrupt
your game check it out at the link below
so let's start then from the very
beginning
it's a good place to start what do you
install the cpu into the cpu socket
where's the socket on the motherboard
where's the motherboard
well here's where we get to step one on
top of a
non-metal non-conductive surface like
the box that it came in
now if you don't have the motherboard
you're going to want to go back a few
steps
and pick one of those up first that's
pretty important
now there are two main types of cpu
sockets that you should probably know
about in 2019
and actually for years to come lga style
sockets
and pga style sockets intel primarily
uses
land grid array or lgas meaning that the
socket itself
is made up of a grid of pins so these
touch gold-plated flat contacts or pads
on the bottom of the cpu and that is
what allows your pc to
run all of your spreadsheet simulators
amd on the other hand
uses more commonly a pin grid array or
pga configuration that means that the
pins are on the cpu
instead of on the socket so pga sockets
are simply a grid of holes
that the cpu drops into with no force
required
now this makes it much safer to handle
the motherboard
without worrying about damaging the pins
which can be
pretty much the end of your cpu
installation endeavor
but it also means that you have to be
extra careful with the cpu
intel actually originally used pgas
but they switched to lga around 2002
presumably because processors are
generally more expensive than
motherboards
and if you're going to accidentally bend
or break a pin
you want your new paperweight to be as
cheap as possible
with that said it's not impossible to
repair socket pins
it's just extremely difficult and
extremely easy to cause even
further damage to other pins while you
try to fix the one that's
bent so your best bet is to send it to
an experienced technician
if you run into this no pressure
but anyway you aren't just concerned
with the type of socket
but also the number of pins so intel's
main consumer socket lga 1151 has
1151 pins while their 2066 socket
which is geared more towards enthusiasts
has 2066 pins
on the amd side am4 has 1331
so if amd was using the same naming
scheme as intel it would be
pga 1331 i guess and then their tr4
socket which is actually an lga
well that one has 4094 pins
which is where things get pretty
confusing because sometimes amd does use
lgas now some of these sockets have been
around for a few years
and may continue to be used by intel and
amd
so something you need to note is that
just because a cpu
physically fits into a particular socket
does not necessarily mean it will be
compatible
and this was a lesson that riley who
prepared this episode
learned all too well in our cheapest
amazon pc video
now sockets are different from chipsets
a specific configuration of hardware and
software that allows the processor
memory and the peripherals in a system
to communicate with each other
processors often launch alongside
compatible chipsets
but sometimes they'll be forwards or
backwards compatible with the next or
previous generation
the thing though is this might require a
bios update in order to work
so you will need to consult your
motherboard manufacturer's website
in order to know 100 for sure which cpus
work and which motherboards and if a
bios update is required
okay so now that we've done our homework
we know our processor is compatible with
our motherboard
it's time to drop that sucker in except
don't actually drop it because as i said
the pins regardless of what they're
attached to are extremely fragile
and susceptible to damage now these
following steps
apply broadly to both of intel sockets
and to amd's am4 socket while tr4
amd's enthusiast socket for threadripper
does do things a little bit differently
before you begin you're going to want to
grab an anti-static wrist strap that's
connected to a ground
or you're going to want to keep your
feet stationary and touch a metal part
of your case or power supply
with your power supply plugged into the
wall to discharge any static buildup
on your body now if you're upgrading
your cpu on an existing system
the first thing you're going to need to
do is unplug your cpu's cooler
so find where the fan cable plugs into
the header on the motherboard
and just pull it off for intel systems
it's pretty common to see these
tool-less plastic pins
installed around the socket simply
rotate them in the direction indicated
pop them open and pull the cpu cooler
off
on the amd side of things you should
find a little lever like this
on one side of the processor socket pull
it up
and the latches on either side of your
cpu should loosen
so you can pull them off the little
hooks on the side and
remove the cooler be careful though it's
not uncommon
for the cpu to get pulled off with the
heatsink
exposing its fragile pins it's not a
huge problem
as long as you don't bend anything
though if you're doing a new
installation rather than upgrading
though
intel lga sockets will have a socket
cover in place
leave this where it is as it will come
off by itself when you lock in the cpu
instead lift up the retention arm or
arms on the side of the socket
this will allow you to lift up the
socket lid next
hold your processor being careful to
only touch the edges
if you touch the contacts on the bottom
not only can this
interfere with electrical contact but it
can actually cause corrosion
over the long term next look for an
arrow in one corner of the cpu
this will line up with a similar marking
on one of the corners of the socket
there may also by the way be notches on
the sides of the cpu
these should line up with tiny nubbins
in the side of the socket
if you're not 100 sure about your arrows
once you've determined the correct
orientation
lower the cpu into the socket gently
there's no need to push
or apply any force
though i do recommend giving it a tiny
wiggle just to make sure that it's
seated properly
and to let it know that you still love
it no matter what
next lower the socket lid over the cpu
making sure that it fits back under the
screw or bracket that held it in
originally
then push the retention arm down and
under the hook so it stays into place
if you've got two arms they'll be
designed so that one goes down
first and then the other just like this
now that process is pretty similar for
most consumer boards and cpus for the
last
10 almost 20 years but amd's tr4 socket
that one's a little more involved your
threadripper cpu will actually
come with the torx screwdriver that you
need to install it
first loosen the three screws holding
down the socket lid
it'll say which order to loosen them in
so don't just unscrew them all
willy-nilly
once you've got them loosened those
screws will stay inside the socket lid
which will pop up on its own
because it's spring-loaded so that's
pretty fun
under the lid you will find another lid
which has a plastic tray inside
lift this lid up holding it by the sides
then slide the plastic tray upward and
then put it away to the side
next is the actual socket cover which
protects the pins
we're just going to leave that there for
the moment now threadripper cpus
come pre-installed into an orange
plastic housing
do not try to remove it it is supposed
to be there
holding it by the tab on one side slide
the cpu
into the rails in that second lid with
the bottom
facing the socket until it kind of
clicks into place
then you can remove the socket cover
from the actual pins
by pinching the grab points in the
middle and then
lower the second lid containing the cpu
now
onto the socket gently push and it will
secure itself into place
at which point you can then lower the
first lid and start screwing the screws
back into place now that torx
screwdriver that's included
is designed specifically for these
screws so once they're threaded in a
little
you can tighten them in the order that's
specified on the socket lid
until the tool clicks and that's it your
cpu is installed
but it won't last very long without a
cpu cooler
now if you have a third-party cooler
that's probably going to come with its
own instructions detailing
how exactly to mount it if it has no
pre-applied thermal paste
you're going to need to add your own to
the top of the cpu before installing
just remember guys that when it comes to
thermal paste
less is more you only need to fill the
small imperfections between the cpu
and the heatsink there's no mystical
pentagram of thermal paste required to
summon the pc gamer gods
that's only going to end up with a whole
bunch of thermal compound all over your
motherboard
which probably won't damage it but it'll
be really messy to clean up
gamer's nexus's modmat actually has a
great guide
for how to apply thermal compound to
most modern cpus
so consumer chips just the small ones a
simple line down the middle is perfect
for intel enthusiast cpus four smaller
dots in each corner will do your wonders
and for thread ripper you want to make
an x with four dots in between the lines
to help fill in the gaps the thing is
that the larger the actual cpu die
under the heat spreader on top is the
more thermal compound you need to make
sure that you get full coverage
because any dye area that doesn't have
thermal compound is going to result in
hot spots on your cpu
which at the very least can limit your
overclocking potential
now mainline processors usually come
with a cooler
while enthusiast ones sometimes do not
now many coolers come with pre-installed
thermal paste on the bottom
in which case there's no need for extra
if you do have a stock cooler
simply line up the four mounting pins
with the four holes on the motherboard
socket
if you're reusing it by the way you will
need to reset those pins
back to their original location and then
push down
on the opposing sets of pins until they
click into place
as for amd it's the same process in
reverse from removal
where we simply hook the side of the
cooler without the latch first
then the latch side and close the arm
now it can sometimes take a little bit
of force
but if you feel like you're overdoing it
then you should probably check the
bottom side
and make sure that nothing's interfering
after your cooler is secured you can
connect your fan
plug into the closest 4-pin header on
your motherboard which will usually be
clearly labeled
cpu fan now that we've got our cpu
installed we could just say
ah that's great let's call it a day but
we won't
because we're professional technicians
it's good practice to make sure that
your cpu is actually
seated correctly and just because the
system boots
doesn't mean that it is so you're going
to want to go into your motherboard's
bios
which is normally accessed by pressing
delete or
f2 when you first power on your system
to make sure that all of your ram sticks
show up it is very common especially on
thread ripper cpus
for some of the pins to not make perfect
contact which can cause
one or more of your memory slots not to
function correctly
if you do run into this it's okay
probably nothing is damaged just go
ahead and take it out
reinstall it and try again and then
that's really it
your cpu is installed the brain of your
system some might call it
treat it well my friends treat it well
