00:00:06.400 --> 00:00:14.639
Linus tech tips is over 10 years old now so it's easy for us to forget that many

00:00:12.240 --> 00:00:19.760
viewers may be encountering the world of pc building for the first time and while

00:00:17.440 --> 00:00:26.160
there's lots of great pc building tutorials out there there are also some

00:00:22.800 --> 00:00:29.760
that verge on misinformation so in this

00:00:26.160 --> 00:00:33.360
video we are going back to basics with

00:00:29.760 --> 00:00:34.559
episode 2 of how to basics

00:00:33.360 --> 00:00:37.719
installing a CPU

00:00:45.440 --> 00:00:48.440
ugh

00:00:59.359 --> 00:01:06.240
the hex gears impulse mechanical keyboard comes with RGB lighting and

00:01:03.120 --> 00:01:08.400
ip56 water resistance so in the event

00:01:06.240 --> 00:01:12.159
that you do spill on your keyboard you shouldn't even need to interrupt your

00:01:09.840 --> 00:01:17.119
game check it out at the link below so let's start then from the very beginning

00:01:15.280 --> 00:01:23.759
it's a good place to start what do you install the CPU into

00:01:20.799 --> 00:01:29.200
the CPU socket where's the socket on the motherboard where's the motherboard well

00:01:26.720 --> 00:01:34.479
here's where we get to step one on top of a non-metal non-conductive surface

00:01:32.320 --> 00:01:38.240
like the box that it came in now if you don't have the motherboard you're going

00:01:36.159 --> 00:01:42.880
to want to go back a few steps and pick one of those up first that's pretty

00:01:40.320 --> 00:01:46.880
important now there are two main types of CPU sockets that you should probably

00:01:44.799 --> 00:01:53.439
know about in 2019 and actually for years to come

00:01:49.439 --> 00:01:56.880
lga style sockets and pga style sockets

00:01:53.439 --> 00:02:00.320
Intel primarily uses land grid array or

00:01:56.880 --> 00:02:02.880
lgas meaning that the socket itself is

00:02:00.320 --> 00:02:09.200
made up of a grid of pins so these touch gold-plated flat contacts

00:02:06.159 --> 00:02:12.080
or pads on the bottom of the CPU and

00:02:09.200 --> 00:02:17.360
that is what allows your pc to run all of your spreadsheet simulators

00:02:14.319 --> 00:02:21.040
AMD on the other hand uses more commonly

00:02:17.360 --> 00:02:23.680
a pin grid array or pga configuration

00:02:21.040 --> 00:02:29.520
that means that the pins are on the CPU instead of on the socket so pga sockets

00:02:26.879 --> 00:02:34.879
are simply a grid of holes that the CPU drops into with no force required now

00:02:32.480 --> 00:02:39.360
this makes it much safer to handle the motherboard without worrying about

00:02:36.879 --> 00:02:44.480
damaging the pins which can be pretty much the end of your CPU installation

00:02:41.599 --> 00:02:50.959
endeavor but it also means that you have to be extra careful with the CPU Intel

00:02:47.760 --> 00:02:54.080
actually originally used pgas but they

00:02:50.959 --> 00:02:56.239
switched to lga around 2002

00:02:54.080 --> 00:02:59.360
presumably because processors are generally more expensive than

00:02:57.840 --> 00:03:04.159
motherboards and if you're gonna accidentally bend or break a pin you

00:03:02.080 --> 00:03:09.519
want your new paperweight to be as cheap as possible with that said it's not

00:03:06.480 --> 00:03:12.800
impossible to repair socket pins it's

00:03:09.519 --> 00:03:15.360
just extremely difficult and extremely

00:03:12.800 --> 00:03:21.040
easy to cause even further damage to other pins while you try to fix the one

00:03:17.680 --> 00:03:22.959
that's bent so your best bet is to send

00:03:21.040 --> 00:03:27.599
it to an experienced technician if you run into this no pressure

00:03:25.760 --> 00:03:33.200
but anyway you aren't just concerned with the type of socket but also the

00:03:30.239 --> 00:03:40.640
number of pins so Intel's main consumer socket lga 1151 has

00:03:36.440 --> 00:03:43.480
1151 pins while their 2066 socket which

00:03:40.640 --> 00:03:51.120
is geared more towards enthusiasts has 2066 pins

00:03:45.440 --> 00:03:52.959
on the AMD side am4 has 1 331 so if AMD

00:03:51.120 --> 00:03:59.360
was using the same naming scheme as Intel it would be pga 1331 i guess and

00:03:56.959 --> 00:04:05.840
then their tr4 socket which is actually an lga well that one has 4094 pins which

00:04:03.920 --> 00:04:10.720
is where things get pretty confusing because sometimes AMD does use lgas

00:04:09.120 --> 00:04:15.280
now some of these sockets have been around for a few years and may continue

00:04:13.040 --> 00:04:21.600
to be used by Intel and AMD so something you need to note is that

00:04:18.000 --> 00:04:24.400
just because a CPU physically fits into

00:04:21.600 --> 00:04:28.639
a particular socket does not necessarily mean it will be compatible

00:04:26.800 --> 00:04:35.199
and this was a lesson that riley who prepared this episode learned all too

00:04:31.440 --> 00:04:38.000
well in our cheapest amazon pc video now

00:04:35.199 --> 00:04:42.080
sockets are different from chipsets a specific configuration of hardware and

00:04:40.320 --> 00:04:45.520
software that allows the processor memory and the peripherals in a system

00:04:44.080 --> 00:04:50.240
to communicate with each other processors often launch alongside

00:04:47.759 --> 00:04:55.040
compatible chipsets but sometimes they'll be forwards or backwards

00:04:52.880 --> 00:04:59.919
compatible with the next or previous generation the thing though is this

00:04:57.520 --> 00:05:04.479
might require a BIOS update in order to work so you will need to consult your

00:05:02.080 --> 00:05:11.039
motherboard manufacturer's website in order to know 100 for sure which cpus

00:05:08.240 --> 00:05:15.840
work and which motherboards and if a BIOS update is required

00:05:13.680 --> 00:05:19.759
okay so now that we've done our homework we know our processor is compatible with

00:05:17.840 --> 00:05:24.960
our motherboard it's time to drop that sucker in except don't actually drop it

00:05:22.479 --> 00:05:29.840
because as i said the pins regardless of what they're attached to are extremely

00:05:27.199 --> 00:05:35.520
fragile and susceptible to damage now these following steps apply broadly

00:05:32.560 --> 00:05:41.600
to both of Intel sockets and to AMD's am4 socket while tr4 AMD's enthusiast

00:05:39.120 --> 00:05:45.199
socket for Threadripper does do things a little bit differently before you

00:05:43.360 --> 00:05:49.520
begin you're going to want to grab an anti-static wrist strap that's connected

00:05:46.960 --> 00:05:54.400
to a ground or you're going to want to keep your feet stationary and touch a

00:05:51.520 --> 00:05:58.800
metal part of your case or power supply with your power supply plugged into the

00:05:56.160 --> 00:06:03.039
wall to discharge any static buildup on your body now if you're upgrading your

00:06:00.560 --> 00:06:07.600
CPU on an existing system the first thing you're going to need to do is

00:06:04.800 --> 00:06:12.960
unplug your CPU's cooler so find where the fan cable plugs into the header on

00:06:09.440 --> 00:06:15.919
the motherboard and just pull it off

00:06:12.960 --> 00:06:21.039
for Intel systems it's pretty common to see these tool-less plastic pins

00:06:18.800 --> 00:06:26.479
installed around the socket simply rotate them in the direction indicated

00:06:23.520 --> 00:06:28.720
pop them open and pull the CPU cooler off

00:06:29.199 --> 00:06:36.639
on the AMD side of things you should find a little lever like this on one

00:06:34.479 --> 00:06:41.440
side of the processor socket pull it up and the latches on either

00:06:39.039 --> 00:06:46.080
side of your CPU should loosen so you can pull them off the little hooks on

00:06:43.120 --> 00:06:51.600
the side and remove the cooler be careful though it's not uncommon for the

00:06:48.240 --> 00:06:54.240
CPU to get pulled off with the heatsink

00:06:51.600 --> 00:06:58.080
exposing its fragile pins it's not a huge problem as long as you don't bend

00:06:56.240 --> 00:07:02.400
anything though if you're doing a new installation rather than upgrading

00:06:59.680 --> 00:07:06.000
though Intel lga sockets will have a socket cover in place

00:07:04.400 --> 00:07:11.759
leave this where it is as it will come off by itself when you lock in the CPU

00:07:09.039 --> 00:07:16.880
instead lift up the retention ARM or arms on the side of the socket this will

00:07:14.319 --> 00:07:22.160
allow you to lift up the socket lid next hold your processor being careful

00:07:19.680 --> 00:07:26.880
to only touch the edges if you touch the contacts on the bottom not only can this

00:07:24.639 --> 00:07:32.639
interfere with electrical contact but it can actually cause corrosion over the

00:07:29.039 --> 00:07:34.319
long term next look for an arrow in one

00:07:32.639 --> 00:07:40.319
corner of the CPU this will line up with a similar marking

00:07:36.720 --> 00:07:40.319
on one of the corners of the socket

00:07:41.520 --> 00:07:48.639
there may also by the way be notches on the sides of the CPU these should line

00:07:46.560 --> 00:07:52.240
up with tiny nubbins in the side of the socket if you're not a hundred percent

00:07:50.479 --> 00:07:56.000
sure about your arrows once you've determined the correct

00:07:53.680 --> 00:08:01.919
orientation lower the CPU into the socket gently there's no need to push or

00:07:59.199 --> 00:08:05.680
apply any force though i do recommend giving it a tiny

00:08:04.160 --> 00:08:08.879
wiggle just to make sure that it's seated properly

00:08:07.199 --> 00:08:14.720
and to let it know that you still love it no matter what

00:08:11.599 --> 00:08:16.720
next lower the socket lid over the CPU

00:08:14.720 --> 00:08:21.280
making sure that it fits back under the screw or bracket that held it in

00:08:18.800 --> 00:08:24.560
originally then push the retention ARM down and under the hook so it stays into

00:08:23.680 --> 00:08:32.640
place if you've got two arms they'll be designed so that one goes down first and

00:08:29.199 --> 00:08:34.560
then the other just like this

00:08:32.640 --> 00:08:37.680
now that process is pretty similar for most consumer boards and cpus for the

00:08:36.719 --> 00:08:42.560
last 10 almost 20 years

00:08:39.760 --> 00:08:48.240
but AMD's tr4 socket that one's a little more involved your threadripper CPU will

00:08:44.959 --> 00:08:50.720
actually come with the torx screwdriver

00:08:48.240 --> 00:08:55.279
that you need to install it first loosen the three screws holding down the socket

00:08:52.880 --> 00:08:59.040
lid it'll say which order to loosen them in so don't just unscrew them all

00:08:57.120 --> 00:09:03.680
willy-nilly once you've got them loosened those screws will stay inside

00:09:01.519 --> 00:09:07.279
the socket lid which will pop up on its own because it's spring-loaded so that's

00:09:06.000 --> 00:09:12.720
pretty fun under the lid you will find another lid

00:09:09.920 --> 00:09:18.480
which has a plastic tray inside lift this lid up holding it by the sides then

00:09:16.000 --> 00:09:23.040
slide the plastic tray upward and then put it away to the side

00:09:20.480 --> 00:09:26.640
next is the actual socket cover which protects the pins we're just going to

00:09:24.959 --> 00:09:33.279
leave that there for the moment now threadripper cpus come pre-installed

00:09:29.920 --> 00:09:35.760
into an orange plastic housing do not

00:09:33.279 --> 00:09:41.360
try to remove it it is supposed to be there holding it by the tab on one side

00:09:38.320 --> 00:09:43.839
slide the CPU into the rails in that

00:09:41.360 --> 00:09:47.600
second lid with the bottom facing the socket until it kind of clicks into

00:09:46.480 --> 00:09:52.480
place then you can remove the socket cover

00:09:50.080 --> 00:09:58.160
from the actual pins by pinching the grab points in the middle and then lower

00:09:55.440 --> 00:10:02.080
the second lid containing the CPU now onto the socket

00:10:00.000 --> 00:10:06.880
gently push and it will secure itself into place at which point you can then

00:10:04.399 --> 00:10:10.959
lower the first lid and start screwing the screws back into place

00:10:09.040 --> 00:10:15.440
now that torx screwdriver that's included is designed specifically for

00:10:13.279 --> 00:10:19.600
these screws so once they're threaded in a little you can tighten them in the

00:10:17.279 --> 00:10:24.399
order that's specified on the socket lid until the tool clicks and that's it your

00:10:22.640 --> 00:10:29.360
CPU is installed but it won't last very long without a CPU

00:10:27.440 --> 00:10:33.760
cooler now if you have a third-party cooler that's probably going to come

00:10:31.279 --> 00:10:37.839
with its own instructions detailing how exactly to mount it if it has no

00:10:36.000 --> 00:10:41.839
pre-applied thermal paste you're going to need to add your own to the top of

00:10:39.680 --> 00:10:46.720
the CPU before installing just remember guys that when it comes to

00:10:43.760 --> 00:10:52.160
thermal paste less is more you only need to fill the small imperfections between

00:10:48.800 --> 00:10:53.279
the CPU and the heatsink there's no

00:10:52.160 --> 00:10:57.440
mystical pentagram of thermal paste required to

00:10:55.279 --> 00:11:00.000
summon the pc gamer gods that's only going to end up with a whole bunch of

00:10:58.800 --> 00:11:04.880
thermal compound all over your motherboard which probably won't damage

00:11:02.079 --> 00:11:09.120
it but it'll be really messy to clean up gamer's nexus's modmat actually has a

00:11:07.120 --> 00:11:14.880
great guide for how to apply thermal compound to most modern cpus so consumer

00:11:12.560 --> 00:11:19.760
chips just the small ones a simple line down the middle is perfect for Intel

00:11:17.200 --> 00:11:24.160
enthusiast cpus four smaller dots in each corner will do your wonders and for

00:11:21.839 --> 00:11:28.880
Threadripper you want to make an x with four dots in between the lines to help

00:11:26.399 --> 00:11:34.079
fill in the gaps the thing is that the larger the actual CPU die

00:11:31.600 --> 00:11:38.560
under the heat spreader on top is the more thermal compound you need to make

00:11:36.160 --> 00:11:43.440
sure that you get full coverage because any dye area that doesn't have thermal

00:11:41.200 --> 00:11:49.200
compound is going to result in hot spots on your CPU which at the very least can

00:11:46.959 --> 00:11:54.560
limit your overclocking potential now mainline processors usually come with a

00:11:51.920 --> 00:11:57.760
cooler while enthusiast ones sometimes do not

00:11:55.600 --> 00:12:02.560
now many coolers come with pre-installed thermal paste on the bottom in which

00:11:59.519 --> 00:12:04.959
case there's no need for extra if you do

00:12:02.560 --> 00:12:08.880
have a stock cooler simply line up the four mounting pins with the four holes

00:12:07.040 --> 00:12:12.880
on the motherboard socket if you're reusing it by the way you will need to

00:12:10.560 --> 00:12:17.519
reset those pins back to their original location and then push down on the

00:12:15.279 --> 00:12:21.279
opposing sets of pins until they click into place

00:12:18.800 --> 00:12:25.920
as for AMD it's the same process in reverse from removal where we simply

00:12:23.440 --> 00:12:30.480
hook the side of the cooler without the latch first

00:12:27.279 --> 00:12:31.279
then the latch side and close the ARM

00:12:30.480 --> 00:12:37.120
now it can sometimes take a little bit of force but if you feel like you're

00:12:35.040 --> 00:12:40.720
overdoing it then you should probably check the bottom side and make sure that

00:12:38.880 --> 00:12:44.560
nothing's interfering after your cooler is secured you can

00:12:42.639 --> 00:12:50.079
connect your fan plug into the closest 4-pin header on your motherboard which

00:12:46.399 --> 00:12:52.000
will usually be clearly labeled CPU fan

00:12:50.079 --> 00:12:55.760
now that we've got our CPU installed we could just say

00:12:53.200 --> 00:12:59.760
ah that's great let's call it a day but we won't because we're professional

00:12:57.360 --> 00:13:04.240
technicians it's good practice to make sure that your CPU is actually seated

00:13:02.000 --> 00:13:07.600
correctly and just because the system boots doesn't mean that it is so you're

00:13:06.480 --> 00:13:12.560
going to want to go into your motherboard's BIOS which is normally

00:13:09.680 --> 00:13:17.760
accessed by pressing delete or f2 when you first power on your system to make

00:13:14.720 --> 00:13:20.079
sure that all of your RAM sticks show up

00:13:17.760 --> 00:13:25.519
it is very common especially on Threadripper cpus for some of the pins to not

00:13:22.560 --> 00:13:30.000
make perfect contact which can cause one or more of your memory slots not to

00:13:27.760 --> 00:13:34.800
function correctly if you do run into this it's okay probably nothing is

00:13:32.560 --> 00:13:39.839
damaged just go ahead and take it out reinstall it and try again

00:13:37.600 --> 00:13:43.519
and then that's really it your CPU is installed the brain of your system some

00:13:42.000 --> 00:13:47.279
might call it treat it well my friends

00:13:45.680 --> 00:13:50.480
treat it well normally these sponsor spots are pretty
