What is ECC Computer Memory? Should You Get It?

Should You Get ERROR CORRECTING Memory for your computer?

ECC Memory, or Error Correcting Code memory for a computer, is a special type of RAM that is meant to detect and fix "flipped bit" errors, where one bit in the RAM is spontaneously flipped for any reason. This doesn't happen often, but sometimes it can cause a total crash of the system, or it can corrupt data. On a regular consumer computer, a flipped bit isn't a disaster, it usually just means you have to restart the computer. But for a mission-critical server, like for finances or scientific analysis, a computer crash or data corruption could be disastrous.

Should I delete system32? I’ve heard it frees up disk space.

There is some special case where you have to use registered ECC memory: registered ECC memory sticks can have higher density than non-buffered ones. There are 16GB sticks of DDR3 memory, but only in registered ECC form. If you have a high core count machine that you intend to run a bunch of VMs on (like LTT's 10-gamer-one-PC rig) you may have to use those high density memory modules so each VM still have enough dedicated RAM

Ram prices have just been disgusting the past few months

[ThioJoe]

Ugh don't you hate when your computer gets all these errors and viruses?

Thanks ThioJoe for this video. I'm learning how to put a server together, and your tutorial on ECC memory was very helpful. Your speech was clear, and you showed a certain mastery of your craft.

No, deleting system32 is more faster and safe.

Crashes due to memory corruption are one issue for which you want ECC memory, but that really misses a very important, if not the most important reason for using ECC memory: corruption of 'in-transit' data.

Changing a few bytes of some spreadsheet or such 'in memory' won't crash your computer, and will initially go unnoticed in many cases, but will end up corrupting your data when saving the file regardless. That is a much more important reason for using ECC memory.

Accidentally clicked on your video because your thumb nail looks like linus from linus tech tips, hope I don't make this mistake again.

As long as I can play free online games at 60 fps, I don't care what RAM is...

[GermanWarrior]

It would probably also be useful in a workstation for airflow simulations so that the aircraft you built won't crash or something like that :)

4:28 Are you saying 00111000 Binary is 8 Decimal? According to my math, it's 56. 8 would be 00001000 and 9 00001001.

I just taught this topic in my lecture today. This video is pretty accurate!

14:02 - 14:07 For a moment, I thought that they were VHS Tapes.

It's not just the motherboard, but the CPU has to support ECC too, and a lot of consumer CPUs like the i5 and i7 don't. Some i3's and Pentiums do though, you have to check Intel's spec page.

[Interestingworld]

But can it run Crysis at 60 FPS and at 4k?🤔🤔

[itzdailymaxis]

Huh, just learned this in school today. So I learned nothing in school I wouldn't have learned 5 hours later. FML

the fun part about knowing how computers work is that you get smart enough to figure that all processors are made up of nano-meter sized transistors. they are gates of electrical flow. there are "and-gates" and "or-gates." depending on whats triggering the signal, whether it should be a 1 or a 0, the CPU stores the data in the Random Accessible Memory Module for it to run programs and more. the data/bits are stored in the hard drive first then the ram. correct me if im wrong with anything.

[PaulTurley]

I have ECC memory in my consumer product motherboard that supports ECC memory in my FreeNAS Server's

If the EU can legally force Apple to switch to USB-C. Why can’t we force manufacturers to make ecc a legal standard?
