Hence why Linux sais "Kernel Panic: Not syncing". It's not syncing to the disk because something has gone catastrophically wrong (e.g. you are dereferencing a NULL Pointer in Kernel-Mode) and it would be unsafe to keep going.

I had a situation about a month ago where one of my RAM sticks was dying and the behaviour you described when "yanking" a RAM stick was very similar to what I was experiencing some times. At first I thought it was the MOBO going kaput but thankfully it was just a single stick. In all due honesty, nobody's going around yanking their components but faulty components can sometimes act like they're disconnected so knowing what it looks like when those things happen is quite useful.

In modern PCs, the CPU isn't who commands the system to turn on (at least not when fully off), it's actually a couple of chips on the motherboard that do: the "SuperIO" along with the "chipset". In my experience, removing the OS drive in Windows doesn't blue screen immediately; instead appears to keep running but simply programs and basic OS UI elements begin to not respond; then the unresponsiveness gets worse over time that the computer becomes unusable. Mouse pointer never freezes, no BSoD, simply becomes so unresponsive that becomes unusable.

Since Windows 8, Windows actually attempts to survive a temporary main drive disconnect. The kernel intentionally hangs practically all processes for a few seconds and sees if the drive comes back online. If the drive comes back, it keeps going as if nothing happened. Only after the drive reconnect window times out do you actually get the BSOD. Presumably, this safeguard was implemented as part of Windows To Go. Windows To Go is a feature of Enterprise versions of Windows that assists users in installing Windows to external, removable storage. It requires fairly beefy, fast USB drives that can tank Windows' space requirements and constant disk activity. As a result of effectively providing official support for installing Windows to external storage, they had to make it reasonably resilient to the boot drive dropping off the bus. Of course, this only works on the internal storage if the system BIOS/UEFI handles SATA/NVMe hotplug. Otherwise Windows is not informed that the drive actually disconnected and instead receives corrupt data, which either crashes or hangs, but the system basically can't recover then. The OS kernels (both Windows and Linux) also support running with less than the total available RAM for debugging purposes. Then, removing a stick of RAM should be safe if it is completely unused by the software and firmware. And whether or not removing the GPU (or any PCIe devices) is safe relies mostly on the hardware and firmware not shitting their pants, and properly reporting to the OS. Assuming the motherboard supports PCIe hotplug, the drivers mostly handle it fine. After all, eGPU drivers come from the same codebase as their PCIe siblings. Linux even supports securely ejecting PCIe hardware the same way it does for USB devices.

It doesn't actually limit you, it's just that the manufacturer (AMD and Intel in this case) have only tested the socket to work for ~10 insertions. It may still work after 100, even 1000, it's just that they never actually cared about making the socket endure this many insertions. At worst, you might not get a warranty replacement if you did it that many times.

Not exactly the same, but related. There’s a technique for reading RAM on a PC that is locked by quickly removing power, powering back up, and then booting into special recovery software. It relies on the RAM not completely losing data for something like a second or two (I forget the actual avg timing). Because of this, there is a chance that you could pull the RAM and very quickly get it into a homebrew device to keep it powered until you get it somewhere safe

I remember the video of Linus doing PCIe hotswapping and the problems it entailed... The only things I know of that really cannot be hotswapped are things like PS/2 keyboards/mice and M.2 drives. PS/2 hotswapping doesn't cause any problems other than the fact that you have to restart the computer. In situations where PCIe, CPUs, RAM and SATA need to be swapped, daughter boards are used and are designed to prevent damage. Even things like power supplies, in servers, can be hot swapped, but you require at least one PSU to be active at all times (which is why redundant PSUs exist).

@redpheonix1000

My experience, mostly with computers that are 20+ years old at this point, is that PS/2 can actually handle being hot swapped and will work just fine after, though this is usually only at the BIOS.

Matter of fact, the channel replied to another comment saying the exact same thing we are. Notice how the three of us also never specified a number - different mobos will have different socket ratings, but even with the scarce amount of research I did (thank you comment/replies :D), the consensus seems that 10 and 20 are the most common values for a given CPU socket rating. It all depends on the mobo. If anything, just another detail to think about when working with PCs :)

the damage is usually caused by a spark that is created for a short amount of time a high potential difference will be generated to damage FET transistors (which are very sensitive), diodes and possibly capacitors therefore a protective circuit is used in external ports to avoid this spark that can damage those components

The CPU will work perfectly fine because CPUs usually have duplicate pins

Well, I happened to know that the LGA 1155 socket used for Ivy and Sandy Bridge was rated for 20 insertions, and that there was a lot of talk when LGA 775 came out about processors no longer being user-serviceable because they don't use PGA anymore... LGA was touted as a reason why only technicians should be installing or removing CPUs now, and people were up in arms about it. Did future processors become that much more fragile? I wouldn't expect LGA 1150, 1151, or even 1200 to be a lot more fragile... but maybe with 1700 pins, now it is so fragile that it can't be replaced more than 10 times.

In the 70s, I programmed on a small main frame, the power went off from lighting, the computer used core memory. When the power came back on, the computer continued processing where it left off with no loss of data.

I used to unplug hard drives and plug them back in immediately to jump start a dead hd, sometimes it worked but more often than never, freezing the hard drive and then hot plugging it in did the trick.

I’ve done this before. I pulled my ram stick out while pc was on. Computer froze but remained completely on with out any problems. Shut pc down removed all power and put ram back in. Started up fine. This is why I love micron ram. I was 14 when I did this by the way. I am 36 now :)

thank you for saving me some experimentation time this weekend.

I must of changed my CPU about ten times before the pins started to bend (Intel S1151), had to try and straighten them again and it can be done, but it's not easy. Also blew up a GPU (years ago, maybe a AGP slot) by not plugging it into correctly, the end of the slot, and one of the pins was burnt.

This is the sort of question I expect my non-techie friends to ask me out of sheer boredom. I'd probably tell them what a dumb question it is, but secretly be like "but what happen though? 🤔"

I really like your videos as I’m not too good with tech things but recently got into learning about them and you explain it very clearly.

For the people gasping at the low rating numbers. These sockets are fragile. They are RATED at these low numbers because the manufacturer can't guarantee the component beyond this many insertions. It will work just fine if you use the slot more times than this on most occasions, but the metal pins may warp and the connections may become less reliable. Especially on LGA sockets.

Once I was wondering why Cities: Skylines was all of a sudden very slow and really bad at drawing light rays like it had to draw them but didn't have any shaders to customise the rending of them. Turned out the HDMI cable was plugged into the CPU rather than the GPU because the monitor was being hot swapped for laptops back them.

I've pulled SATA-DATA from System's (Win10) drive by mistake yesterday, due to poor connection. System wasn't responsive, but was able to start browser and even task scheduler. This data was probably cached in RAM anyway, and a few minutes later completely froze, even tho the cursor was moving. No BSOD appeared. The system was a haswell-based desktop I believe. I'm surprised you've mentioned U.2, but not SAS or IDE.

Ahh yes the age old question

Wow .. only 10 insertions over its whole lifetime? That's rough.

Back in the day, I used to plug 1060 to a laptop using a riser cable to mini pcie. Hotplug worked if plugged in while in bios or in bootmanager os select list (I.e before os boot).

Never found out why it sometimes worked and other time didn't.

The system crashed and would not power on until i unplugged it.

When it comes to sudden removal of the GPU the ability for the OS to recover is dependent on the PCI Express controller being able to notify the operating system that a card has been removed.

The risk depends on how good the protective circuitry around the PCIE lanes is.
