Why is the default settings for cores always set to one core?

[Aqian1]

On youtube there is this guy called ThioJoe and most of his videos are just clickbait and fake videos. However on one of his videos he said that that default settings for PC's were set to 1 core in order so that in the future once that 1 core died you would be able to use the other stored ones. He also said that using more cores would eventually damage them but would give you better performance. Im not sure if this is true or not but if you guys could give me some insight that would be great.

Consider the source. Why would you consider this any more valid than his clickbait and fake videos?

BTW, it's not true. The BIOS will detect all cores. Look at the Task Manager Performance tab on the machine you are using now. How many cores does it show? Did you have to change some setting to make those extra cores show up?

At first I thought it did not but it turns out after I changed it to my maximum of (8 cores) back to the unchecked default box that they use the same number of cores and processors. But would it be bad for my cpu if I used all of my cores? Would any damage be done to my computer? Sorry I am not very good with computers and am trying to learn.

What a bunch of crock !!! Cores are there to be used, everything is made to work like that and there's no spare cores.
It's amazing how much pure bullshit you can find on Youtube !!!
I must look at that, need a good lough !!!

I don't know what box you are checking or unchecking but yes, you could damage the machine if you don't have sufficient cooling to run 8 cores at the same time.

For heaven's sake guys, if MB is made for and supports 8 cores it's made for it and it's totally safe. Also in case of AMD processors 4, 6 and 8 core processors of same series have same TDP,
FX 4300, 6300 and 8300 all have TDP of 95W so if you turn off 4 cores in 8300 you'll still have same TDP as 4300. They all use same voltage at same frequencies no matter how many cores are active so TDP stays same. Just because you turn a core off in bios it doesn't mean it's not powered on.

Thanks for the response. I have a i-7 4790 processor so I am pretty sure I can run the 8 cores.

Except it doesn't have 8 real, physical cores but only 4 and 8 threads so it uses power for 4 cores only.
