random access memory.
00:10
In this demo, we will look at random access memory, or RAM.
00:14
More specifically, we will be looking at the primary system RAM called Dynamic Access Memory, or D Bram,
00:22
although for the majority of this demo we will refer loosely to it as RAM or memory.
00:28
RAM comes in several shapes and sizes, and it is important to understand the types of ram that are out there.
00:34
Therefore, in this devil, we will briefly examine some of the types of ram you are likely to encounter.
00:40
We will also look at how to install RAM in a typical desktop PC motherboard.
00:46
Last, we will examine how to verify that the installed Graham is detected by the operating system and how to test the ram for any issues.
00:55
First, let's look at a stick. Aram. This is an example of DDR two e c C synchronised D ram,
01:02
which would typically be used in a server.
01:04
Ram, comes in many types.
01:07
Most modern systems use synchronised D ram or SD ram.
01:12
SD RAM acts much like de Bram,
01:15
except that it sinks with the system clock.
01:18
Hence the name synchronous.
01:21
This stick of ram is an example of SD Ram,
01:23
the D D R stands for double data rate.
01:26
The two represents that it uses DDR to a successor to the first DDR
01:32
note. DDR two is not compatible with regular DVR. Both DDR and DDR two are considerably faster than regular SD ram.
01:42
However, they rely on a dual channel architecture. This means that two identical sticks of DDR RAM should be used together and you need to pair them by placing them in the appropriate slots on the motherboard.
01:55
E. C. C stands for air correction code. This particular stick of RAM has support for E. C. C, and therefore can detect if there are incorrect bits and fix the errors on the fly.
02:06
Ram sticks can have differing configurations and numbers for the connection contacts these air, most commonly referred to as pins.
02:15
This stick of RAM has 240 pins
02:17
which are located on the front and backside.
02:21
However, there are many potential configurations, including those with 100
02:27
144 168
02:30
1 72 1 84 200
02:34
to 14 to 40 and 244 pins.
02:38
Also, take a note on the slot, dividing the groups of pins and the slots on both the right and left hand side of the ram.
02:47
These will be important when installing the ram.
02:51
We will examine these aspect shortly.
02:53
Further. It is crucial that when ordering or installing Bram, you consult the manual for the motherboard or device you are working with.
03:01
It will provide information on which types of ram or compatible.
03:06
Let's look at a few more examples of common types of ram.
03:09
These two pieces of RAM are from laptops thes air, both examples of DDR two so dim memory with 200 PIN connections,
03:19
the sodium stands for small outline duel in line memory module.
03:24
This basically has a smaller form factor than regular ram sticks and instill a type of SD ram.
03:31
Both examples do not have eric correction codes support like our previous example.
03:37
Likewise, the remainder of the examples on this light are non E. C. C, which is common for work stations in laptops.
03:45
The next stick of Ram is an example of DDR SD RAM
03:50
notice the difference and the density of the pins on this stick of ram compared to the one below it.
03:55
This stick of RAM has 184 pins.
04:00
In the next section of this demo, we will examine how to install this stick of RAM in a typical desktop PC motherboard.
04:08
The last example is of a stick of DDR. Three SD Ram
04:13
D or three is a successor to both Dior and DDR two and supports triple channel architecture.
04:20
It also uses 30% less power than DD or two.
04:25
However, like DDR two DDR three RAM is not compatible with others, including DDR and DDR to RAM.
04:34
Also note that this RAM has 240 pens,
04:39
notably, it also has an aluminum heat spreader that encloses the memory modules and helps remove heat.
04:46
Next, we will look at how to install RAM.
04:49
Specifically, we will examine installation of a stick of ram in a desktop PC motherboard.
04:56
To do this, you will first need to locate the proper slots for the RAM.
05:00
If needed, consult the manual for the motherboard.
05:04
It will contain information on what types of ram are compatible with your board.
05:10
As you can see for this motherboard, there are two empty slots for Ram.
05:14
You should also consult the manual of the motherboard to determine which slots are optimal for installation of the ram that you have available. For example, RAM with dual channel support can require that the ram sticks be identical.
05:29
Furthermore, some motherboards require that RAM is placed in certain paired slots.
05:34
You may also need to consider if you wish to insert on additional odd number of RAM sticks.
05:42
In some cases, the dual channel mode can be deactivated when there are not completed pairs of RAM sticks.
05:49
Let's look a little closer at the Rams slots.
05:53
First, note the tabs on the left and right sides of the slots.
05:58
When Aram Stick is fully inserted into a slot, the tabs will move inwards towards each other and click into place and the slots on the side of the ram sticks.
06:09
Next, we will insert the rams. Take carefully into one of the slots When handling the ram or any other component. It is important to make sure you wear an anti static bracelet and ensure all power sources have been disconnected.
06:25
Here. You should know a couple of important things. First, the Ram's stick will align with the slot and can be lowered in vertically from above,
06:33
However, there is a problem.
06:35
We have not properly aligned the ram steak with the slot.
06:40
Note the groove in the Ram stick and consider the divider in the slot
06:45
before inserting a ram stick. Take extra care to make sure the pens will align correctly and do not forcefully insert a ram's stick.
06:54
If we turn around the ram's stick,
06:56
the pins and this lot will align properly.
07:00
Apply firm but not excessive force to the top of the Rams *** pushing the stick into the slot.
07:06
Make sure to engage the tabs on the sides of the Ram stick.
07:12
When you have fully seated the Ram's stick and have engaged the times, the ram should appear as shown.
07:17
Now that we have installed the Ram, it is time to see how we can make sure it shows up with the computer's operating system
07:25
and tested for any potential errors or issues.
07:30
In order to verify the installed ram,
07:32
we can see that it is detected by the operating system. Additionally, we can run memory testing utilities to verify that there are not any defects.
07:44
We will look at how it's a verify the amount of RAM installed on a computer using the Windows eight operating system. We will then look at an example of how to run the Windows Memory diagnostics tool and Windows eight to see if there are any issues with our RAM.
08:01
First, let's take a look at how to verify the amounts of RAM installed on the system
08:07
in Windows eight. First, perform a search for the available applications.
08:13
You can get to this menu by hovering the mouse in the upper right hand portion of the screen
08:18
in the search box. Type the text system Information
08:24
as you are typing the text on icon for the program should appear as shown.
08:28
Click on the system information icon and the program will open.
08:33
We want to examine the contents of the system summary
08:37
to do this select system summary on the left hand side of the screen has shown.
08:41
Next, look through the entries on the right and find the entry installed Physical memory as shown
08:48
as you can see here. The entry indicates four gigabyte of ram are installed.
08:54
Next, we will examine how to use the Windows Memory Diagnostics tool
09:00
to check of our Ram has any issues
09:03
In order to use the Windows Memory Diagnostics tool, we need to first locate the application
09:09
again. We will use the search feature to locate the application
09:13
in the search box type Windows Memory Diagnostic
09:18
as you are typing the text on icon for the program should appear as shown.
09:24
Once you have click the Icon, you will see the following pop up window for the Windows Memory Diagnostic program.
09:31
Click the restart now and check for problems Button
09:33
and the system will restart.
09:37
Once the system reboots, it will load the windows Memory Diagnostic Tool has shown
09:43
You may need to wait a while while the test complete,
09:48
the program will run and automatically restart the computer. When complete, you won't need to log in. Normally, we will then look for the test results.
09:58
Once you have logged in, name Papa will appear in the Windows Notification area, indicating results are available from the Windows Memory Diagnostic tool.
10:09
One example of the pop official.
10:11
You can see it in the summary that no memory errors were detected.
10:15
If you click on the pop up, you can see a more detailed report.
10:18
However, it's sometimes hard to catch the pop up in time
10:22
so we will examine on alternative approach.
10:26
You can access the results from the test through event viewer To access the event viewer, do another search and type in event viewer, the AP should appear Russia.
10:39
The Windows Event viewer program showed open as shown
10:43
in the Windows Event viewer Expand the Windows Log folder and select system as indicated
10:50
next, Examine the log file entries in the middle top portion of the window.
10:56
The log file we're looking for are the ones with the source I d memory diagnostics results
11:03
note. The test was ran twice by the utility so we have two results with the event I. D. S 1101 and 1201
11:16
Looking at event 1201 You can see the diagnostic completed without detecting errors.
11:22
This completes our demo examining random access memory
