Any Good Tutorials?

Hello Forums,

I find that Linus often talks above my ability to follow. My knowledge has always been rather spotty on the pc building side, but I would really like to learn more. I have quite a bit of entry level general technician knowledge, so I am not completely computer illiterate.

Does any channel have a playlist of absolutely everything you need to know? Something that just goes sept by step through every single part of a computer, and explains it in great detail. Like I watched a non LTT video recently were it said that that is no benefit to above 3000mhz ram outside of overclocking, but then what about ram latency? And then it was talking about single vs dual bank and I am still not even sure what that is exactly. And I know that whenever Linus build a PC he puts like 8 noctua fans in it, but I am not sure if that is how everyone should be building PCS, or noctua just pays him to do that.

That's the problem with watching something and not truly understanding it or filtering what he says.

 

There's no benefit to above 3000 Mhz on SOME PROCESSORS / ARCHITECTURES. The advice may not apply to future processors released. In technology things change.. and change often.

 

For example, a lot of Intel processors don't show any noticeable performance increases when you configure memory above 2666-2933 Mhz.

Ryzen processors however are designed differently, and do benefit from higher frequency ram... there's a noticeable performance increase from 2666 to 3000, there's a less noticeable performance increase from 3000 to 3200, and still some performance increase but quite small from 3200 to 3600 mhz.

Ryzen 1xxx had difficulty using ram up to 3200 Mhz, Ryzen 2xxx series improved ram support and compatibilty and can handle 3200 Mhz just fine and even does 3600 well on majority of motherboards, and Ryzen 3xxx and 5xxx actually work best with 3600 Mhz memory... but as the performance jump is not that high, using 3200 mhz memory would be acceptable. 

 

single rank and dual rank ... how the tiny memory chips are arranged on the ram stick ...  a ram stick is 64 bit wide, and each tiny ram chip is 8 bit wide, so you need to use 8 tiny ram chips or multiples of 8 tiny ram chips to form a ram stick.

If you have 16 ram chips on a stick, you can group the ram chips in two ranks of 8 chips and the memory controller inside the cpu can work with each rank independently. For example, it can send a command to fetch some data to both ranks knowing it takes a few nanoseconds for the data to become available and as soon as it's done transferring data from one rank, it can start fetching data from 2nd rank without delay.

Dual rank sticks are harder to control / drive by the memory controller and are often less good at overclocking. You may have situations where you can easily achieve 3600 Mhz on a budget motherboard with just two sticks installed, but when you install 4 sticks you may only be able to do 3200 mhz or even 3000 mhz. 

 

fans... you need to make some air flow through the case. You don't need lots of fans, you just need to be figure out how much heat components generate and how to position at least a fan to push air through the case. Warm air rises, so even a single fan is enough to generate some air currents through the case.

if you have some cheap low power video card and a cheap 65w tdp processor, you don't need 8 fans, because those two parts don't produce enough heat to even cause issues without fans installed.

So couple of things. You have two sides of things. There's the "What does X mean" side. Which is pretty much why Tech Quickie exists. Here's the playlist, but you need to go back to beginning for those level-0 videos https://www.youtube.com/playlist?list=PLQMVnqe4XbictUtFZK1-gBYvyUzTWJnOk

Time to time they do make other videos talking about something, explaining stuff. Like this one about motherboard features:

 

From other youtubers, this one is older, but explains some basic stuff about BIOS options:

 

My own knowledge comes from reading. Back then it was magazines, and I've learned PC building from written guides. You pick up stuff by just being curious and reading.

 

PS. Here's video about how many fans you would ever need https://www.youtube.com/watch?v=8OmkmluAYAQ

Do you have any specific recommendations, I am open to non-video sources. Been working my way through tech quickies slowly.

The problem with such things is they can change.  For 9th gen intel that memory is very arguably true.  There was testing done on Ryzen2 that showed what looked like useful upticks in performance up until 3600 MHz.  There currently often isn’t a really useful gain to be had by m.2 drives over sata SSD, that is expected to change though.

Pick a review site and start reading. AnandTech, TechPowerUp etc. The reviews and news usually go through in-depth about technology besides actual performance. Like I said, my knowledge comes from time before Youtube and when actual printed magazines were a thing. Back then even Wikipedia was not option.
