>> Welcome to the CompTia A+ 220-1001 Module 2.
00:01
This is Lesson 3.5: Troubleshooting and Installing RAM.
00:01
Installing RAM and recognizing problems
00:01
that can occur if not installed correctly.
00:01
I'm instructor Bill Price.
00:01
Our lesson objectives for this lesson
00:01
is RAM installation overview,
00:01
installing the RAM, and troubleshooting RAM.
00:01
Let's go and jump right in.
00:01
First, let's start off with
00:01
a little RAM installation overview.
00:01
Now, one of the easiest upgrades that you can make to
00:01
your system is installing or increasing the RAM.
00:01
Nine out of 10 times,
00:01
this is going to be
00:01
the only reason that you're going inside
00:01
of your case except for if
00:01
you were adding in a hard drive or tenure
00:01
hard drive or other add-on
00:01
cards like a NIC card or anything like that.
00:01
For the most part,
00:01
the most time that you're going to be inside of
00:01
your case is installing memory or upgrading your memory.
00:01
Before you start your installation,
00:01
make sure that you consult
00:01
your motherboard manufacturer to make
00:01
sure what type and how
00:01
much RAM your motherboard could take.
00:01
You don't want to get into a problem
00:01
where not knowing for sure and
00:01
going into the installation only to find
00:01
out that it does not work with your motherboard.
00:01
Again, consult your motherboard manufacturer
00:01
to make sure what type
00:01
of RAM that your system can take before
00:01
ordering it and installing, of course.
00:01
Let's go ahead and jump into the lab.
00:01
I will be installing a RAM module in
00:01
a desktop motherboard as well as a mobile device.
00:01
Let's go ahead and jump in and
00:01
have a look over in the lab.
00:01
Here we go with our motherboard here in the test lab.
00:01
I'm going to show you how to
00:01
install a sticker RAM into our motherboard.
00:01
What you want to do is you want to go
00:01
directly on top of
00:01
the slots and install your RAM that way.
00:01
We will see the slots
00:01
that I have right here that I'm going to be
00:01
installing my bank RAM in this first slot right here.
00:01
You can notice that the tabs are down.
00:01
But watch when we insert the RAM.
00:01
Again, we're going to take the RAM and
00:01
go straight in this way,
00:01
fit it into the grooves.
00:01
Making sure that again,
00:01
you've already checked your motherboard
00:01
manufacturer's paperwork and documentation,
00:01
so you know have the right type of
00:01
RAM that will fit your motherboard.
00:01
As you can see here,
00:01
my memory module lines
00:01
up with my slots on my motherboard.
00:01
If you want to zoom in and look at that,
00:01
you can see that those slots line up.
00:01
We want to go straight in,
00:01
making sure that's aligned,
00:01
and we press the memory modules
00:01
straight in just like that.
00:01
As we push that in,
00:01
you can see that on the side here that
00:01
these tabs fold in and lock the memory module in place.
00:01
Before they were down,
00:01
but when you press the memory module in,
00:01
they close in and make sure that they're locked in,
00:01
so that memory module is ready to go.
00:01
Let's do that again. I'm going to pull
00:01
these tabs down just like this,
00:01
and like so and I slide my memory out.
00:01
Those tabs lock that memory module in place.
00:01
Again, I go straight down into
00:01
those slots lining my memory module in, then I press.
00:01
[NOISE] Those tabs lock that memory module in place.
00:01
We've just installed a stick of
00:01
RAM into our motherboard,
00:01
and we're ready to go to add additional memory modules.
00:01
Or if that's all the memory
00:01
that we're adding, we're done.
00:01
It's just a simple as that.
00:01
Troubleshooting steps here.
00:01
If you were to boot your computer up and of course put
00:01
a monitor and a keyboard
00:01
and power supply in this motherboard,
00:01
and you boot it up and see
00:01
that it doesn't recognize the memory module,
00:01
then you know, it's probably not seated correctly.
00:01
You probably didn't get those clicks,
00:01
that memory module is not all the way in the slot.
00:01
It could be just a few other things.
00:01
It could be the wrong type.
00:01
If you didn't consult
00:01
your manufacturer's motherboard documentation.
00:01
If this was the only RAM in
00:01
this board or only memory module in this board,
00:01
and you did not seat this properly,
00:01
your computer will give you
00:01
a warning signal, a warning tone.
00:01
We learned about those in earlier lessons.
00:01
The BIOS beep codes.
00:01
When you boot up your system,
00:01
all manufacturer's systems have some type of system of
00:01
letting you know if something is wrong with the memory,
00:01
if it did not read the memory correctly,
00:01
or some type of system information letting you know
00:01
what type of and
00:01
how much memory that you do have in your motherboard.
00:01
What if I was installing
00:01
a memory module to
00:01
a mobile device such as this laptop right here.
00:01
It's pretty much the same straightforward setup,
00:01
but it may be a little bit differences,
00:01
depending on the manufacturer of your mobile device.
00:01
On this laptop right here,
00:01
you can see that I have the battery move.
00:01
On this particular model,
00:01
there is a compartment here at the bottom of
00:01
the laptop that the memory is installed in.
00:01
Some laptops, you may have to remove
00:01
the entire board here at the bottom.
00:01
But this particular model, we're just going
00:01
to be removing this door right here.
00:01
It's two simple screws that I will be
00:01
removing off, like so.
00:01
[NOISE] Removing that door.
00:01
There you have it. That is
00:01
the memory module that's inside of that laptop there.
00:01
If you can see there's still
00:01
those two tabs or two notches
00:01
a little bit differently on
00:01
a laptop than it is on a desktop,
00:01
but it's still the same principle.
00:01
There's a notch here and a notch here,
00:01
and they hold these memory models in place.
00:01
If you remember from
00:01
our earlier lesson that
00:01
this is the SO-DIMM or the SODIMM.
00:01
Those two notches are holding that in place.
00:01
If I wanted to remove or install more,
00:01
I would take these two notches and pull
00:01
them apart like that
00:01
and you can see that the memory module raises up.
00:01
You would remove the old module
00:01
and replace it with the new module, just like that.
00:01
Get it into the correct slot in the groove,
00:01
like such, press down
00:01
and those two notches right
00:01
there holds that memory module in place.
00:01
Of course, you would replace your door,
00:01
put your battery back in and boot your laptop on.
00:01
After you boot it up again,
00:01
you'll still check the operating system
00:01
to make sure it recognized your memory.
00:01
But straightforward, very simple to do
00:01
as far as installing
00:01
more memory into your laptop or mobile device.
00:01
Now that we've installed the memory modules
00:01
into our devices, like I said before,
00:01
a lot of modern systems on
00:01
the market now you can be able to go into
00:01
the UEFI BIOS to see
00:01
your memory if it was taken or so forth,
00:01
and it will register here,
00:01
as well as the operating system.
00:01
You can go into the operating system on
00:01
any modern operating system like Windows 10, Windows 7,
00:01
even the earlier Windows operating systems,
00:01
or other operating systems,
00:01
and it will tell you how much RAM that you do
00:01
have now installed into that particular system.
00:01
RAM installation tips, consult
00:01
your motherboard manufacturer for
00:01
your systems RAM type and limitations.
00:01
Again, I can't stress enough, this is very,
00:01
very important that you do consult your manufacturer of
00:01
your motherboard again to make sure
00:01
what type of RAM and its limitations.
00:01
Line up the notches or
00:01
the notch on the RAM module to the socket,
00:01
make sure it lines up.
00:01
Make sure that your RAM is fully installed or
00:01
seated and that the channels are properly filled.
00:01
Again, we learned from our earlier lessons
00:01
about channels sometimes you have to,
00:01
depending on your motherboard type and
00:01
manufacturer, match your channels.
00:01
Some channels, may be A, B, C, D,
00:01
it may be AA, BB, CC, DD, and so forth,
00:01
or it may be 01, 02, 03.
00:01
Depending on the configuration,
00:01
if you had a dual-channel, triple-channel,
00:01
you'd have that installed matching sets of RAM,
00:01
two in the B channel,
00:01
two in the C channel, and so forth.
00:01
Make sure that the channels are properly filled.
00:01
That's number 1 problem
00:01
or a main problem that can happen,
00:01
as far as when you have problems
00:01
with your system not installing RAM,
00:01
or you may get beep codes.
00:01
Watch when your system boot up to see if
00:01
the system was properly installed.
00:01
It may boot up,
00:01
and you may see that you were trying to
00:01
install 32 gig and only see 16.
00:01
What happened to the other 16?
00:01
You'd have to go back and
00:01
shut the system down and go back in to
00:01
see if it was properly seated or could
00:01
have been speed mismatch or something like that.
00:01
Troubleshooting RAM installations.
00:01
Every monitor system will have a way of
00:01
displaying the amount of RAM in your system.
00:01
Like I said, if it's either in
00:01
the BIOS or the operating system,
00:01
it will show you the amount of RAM
00:01
that you have installed at that current moment.
00:01
If you're not seeing the amount of
00:01
RAM that you installed most of the time,
00:01
it's a simple installation error.
00:01
It could be a channel problem, like I said before,
00:01
it could be mismatched or not properly filled.
00:01
It could be a speed issue,
00:01
meaning the rated speeds so
00:01
the memory models may be different or mismatch.
00:01
Make sure you check that as well.
00:01
Or it could be that the RAM module
00:01
is not properly seated.
00:01
If any of these problems happen,
00:01
check your installation and make sure
00:01
that your RAM is seated properly.
00:01
That was a quick lesson where we
00:01
installed RAM into our motherboard.
00:01
We installed it into
00:01
a desktop motherboard as
00:01
well as a mobile device, a laptop.
00:01
We started off with a RAM installation overview,
00:01
installing the RAM,
00:01
and troubleshooting the RAM installations.
00:01
That is it for this lesson,
00:01
and we will see you in the next lesson.
