    So, you are building a pc or just want to upgrade your old desktop or laptop and you
    need RAM!
    So let's check it out!
    If you don't care about what exactly RAM does and what role it has in your system,
    then you can skip to the time shown on your screen right about now.
    If you want to find out, keep watching.
    Ok, are they gone?
    Good, now let's get into it.
    RAM or Random Access Memory is somewhere in beween the speed of your Hard Drive or SSD
    and that of Cache memory.
    If we were to make an analogy to something that everyone has done at least once, we would
    use food.
    The CPU wants data, so that is your stomach, which wants food.
    The fastest and most readily available place where it can get food is your mouth.
    That would be the cache memory.
    Now, the problem here is that neither your mouth nor cache memory can really store a
    lot of food or data at any time only a few megabytes.
    On the other hand, a hard drive can store a lot of information.
    In our analogy, that would be a fridge.
    There is a lot of food in the fridge, but it would really slow down your eating if every
    time you wanted to put something in your mouth (or cache memory) you had to go, open up the
    fridge and dig around for whatever it is you're craving.
    Here's where the RAM comes in.
    The RAM is the plate sitting in front of you on the table.
    It stores things that your CPU system is currently using or that it is planning to use in the
    near future.
    Similarly, the plate holds the food that you are currently planning to eat, because it's
    more readily available that if it were in the fridge and it isn't feasible to put
    everything in your mouth all at once.
    OK, so now that we know what RAM does, it's time to figure out if it will work with the
    rest of your rig.
    When it comes to RAM compatibility, it almost always relates to your motherboard in some
    way, so before you get going, you want to find out what motherboard your system has.
    If you're not sure how to go about that, I have a video on that topic that you can
    find by clicking the card in the top right corner of the video.
    Go watch that and then come back here.
    Alright.
    First up let's make sure that you are getting the right generation of RAM, which is usually
    expressed "DDR" and then a number.
    Your motherboard will specify what type of RAM it supports and it will most likely be
    DDR4 or DDR3.
    DDR2 is really old and unless you have a PC that has seen quite a bit of history, it's
    unlikely for you to have that.
    You could also find motherboards that simply say they support DDR.
    That is basically DDR1, the original version, which is incredibly outdated by now.
    Now that you know the generation of RAM that you can get, let's ensure you don't get
    too much of it.
    Every motherboard has a maximum amount of RAM that it supports.
    Whether it is 32, 64, 128, 256GB or whatever other amount, make sure you don't get more
    than that, because that would just be a waste.
    It is also worth checking how many DIMM slots your motherboard has.
    Those are where you plug your RAM in.
    There's usually 4 of them on normal size ATX motherboards, but their number goes anywhere
    from 2 on compact boards to 8 or even more high performace premium boards.
    For example, if your board has 2 slots, don't buy 4 sticks of RAM, obviously.
    Speaking of more than one DIMM slot: if you are trying to upgrade a system, you want to
    make sure that you aren't mismatching RAM.
    Ideally, all of your sticks should be completely identical.
    You need to find out what RAM is already installed in that computer and see if you can get your
    hands on more of the same ram modules.
    If that is not an option, make sure that the Frequency (also known as Speed of the RAM),
    Capacity and Latency is the same for the RAM you are buying and the one that you want to
    pair it with.
    One other thing that is easily overlooked is RAM clearance.
    Here's what I mean by that: If you have a particularly compact board, a really huge
    CPU cooler or super tall and bulky RAM, you might find that the CPU heatsink will overlap
    the DIMM slots, not letting you plug your memory in.
    To prevent this, you can do a quick google search for the CPU cooler that you are looking
    to pair with your motherboard and RAM and see if you can find people complaining about
    RAM clearance issues.
    While on the topic of size, it is good to know that if you want to buy RAM for your
    laptop, then you need to look for SO-DIMM sticks.
    Laptops use SO-DIMM slots unlike the usual computer DIMM slots for DIMM sticks.
    It's just a different size format and other than that the whole compatibility side of
    things is the same, so everything we've said before still applies here.
    So, to summarise, here's what you need to check when buying RAM: is it the right generation?
    Am I getting the right size format (DIMM for PC's and SO-DIMM for laptops)?
    Do i have enough slots on my motherboard?
    Does my motherboard support the amount of RAM that I am planning to get?
    Will my CPU Cooler leave enough room for my RAM to be mounted?
    Am i getting modules that have the same specs?
    If the answer to all of those questions is YES, then you are good to go!
    And that's about it!
