My old Z77 Intel motherboard actually allows PCIE hotswapping. I wouldn't expect and GPU to connect without some work though considering how low level the drivers are, but a sound card or SSD work just fine.
If you use motherboards that are designed to do that, yes. In which case you'd use server/mainframe parts anyways, and I'm assuming you are talking about standard ATX MBs, so no, since those standards are not designed for multiple boards connected together. However, with enough time, effort and budget, you could modify a board to boot 2 machines as one, but that would probably just end up being a more janky version of rack modules.
You would need a sata cable adapter that runs one sata into 2 satas. Or you'd need a harddrive with 2 data connection ports. But I think neither one of those has been made
Also, a "supercomputer" can be made with one board, if it has enough pci-e connectors. Some have been made already, connecting co-processors to the slots
@@burner2894 you're talking about one drive being used by 2 computers? You could do that by setting up one of them as a storage server and connecting them via ethernet
I'd love to actually see what happens if you cut the power during a bios update. I know it makes the motherboard unbootable but I'd love to see what would happen when you turn it on.
I work in IT for a school district and I have seen this happen to one of our desktops before, it’s pretty anti climatic. Pretty much when you try to turn the computer on the screen starts to turn on, but never reaches post (no dell logo or etc. shows) before it turns off. Depending on the computer you may have the power button indicate a sort of Morse code using different colors and different lengths of led pulses to indicate a troubleshoot code. Typically it’s orange and white for Dell. May also give a little chirp on the on board speaker.
@Keep Looking Up If you want to start as an intern you may be able to check the school district's technology department's website for any job postings as they may be listed there. If you cant find it give them a call and ask if there are any intern positions which are currently open or may be opening sometime in the future. If you wish to skip being an intern I would recommend getting an associates/bachelors degree, IT certificates such as the A+ cert, or experience within the IT field elsewhere. This will set you apart from the other people also applying for the position. (They may not require the degree or certs but this will increase your chance of getting hired over someone else greatly). I would recommend getting your A+ cert if you can. I worked for the technology department as a paid intern during the summer before going back to college for the school year. After doing that a few times they ended up offering me a full time position. One thing I will say is many school districts like hiring past students who attended so if the one you are interested in is the same one you attended, make sure to let them know you went there! I wish you the best of luck!
To some PC's you can, meanwhile the older computers might lack hardware to take more than 1. I got an older PC that could take a 2nd card just doesnt fit in the current tower its houses in
Okay but.. why? That isn’t even interesting, it’s just.. taking away any shot at cooling. The IHS is just a slab of metal that lets the thermal paste and CPU cooler do it’s job. You’d get the same effect of taking the IHS off, just by using it normally without any cooling.
As a software developer that makes super much sense. Anything else would be architectural crazy. Imagine the system uses resources and has to scan constantly for an appearing connection. The bus probably gets initiated at startup, since it’s a bidirectional communication.
I do this at home, all the time. Built computers for over 20 years; never experienced an issue hot swapping a live destkop. Anything on PCI is safe to do this, power cords and all.
Expect some 30% chance Vcc and Data will gain connection before Gnd, and as result full current will flow through data lines totally evaporating these nanometer paths in the integrated circuits. It's totally luck-based.
you need to not forget that PCI express was made for hot plugging. it is like your usb3 type c for your smartphone. In this case, the only problem we can have is like for the graphic card: what the component nood for working.
(Not an Expert) There are a number of reasons on why the second didnt show up but did power up, power alone is provided to all lanes reguardless of anything. 1) The bios can configure the PCI lanes automatically upon boot. lanes not in use get dropped by bios and thus cant be used after boot. My old board does this but can be set to manual to keep these lanes active. (Example: lane 1 might get x16 lane config on boot while the rest get x0 resulting in that lane to get no attention and the focus being the one with a gpu) 2) The drivers upon boot probably expect to see the graphics card then. Since it was after the drivers wont link to the new card cause it was not expected that a new card was to be added 3) I have before plugged in wireless network cards before while running and would show up however i think the graphics lanes handle things differently as per previous explanations. 4) it could even be the time it took for all the pins to make contact resulting in an error being thrown and the computer or gpu bios yo refuse to continue to interact with the card. If anything you sgould check device manager to see if windows even sees it. even if it the gpu doesnt show in task manager it should show up in device manager as something, may or may not be classed as a gpu but maybe classed as an unknown device. if windows doesnt see it at all then that means the bios side is the cause where recourse allocation already took place. (back to my example above below 1)
I think Linux it would actually work because gpu driver will be in a kernel module and not in the kernel itself. So as long as you restart the module it should run fine
you can try and call it by going into device manager, right click computer name and select 'scan for hardware changes' Depending on how the PCIe bus it set up, it may install.
go to device manager and physically click scan for hardware changes... you'd be surprised how many things don't natively spring to life without actually manually searching for it. More than half the time you'd be able to get a default Microsoft driver to run without reboot.
This is in part because BIOS is only read during bootup. PCIe on its own cannot be hotswapped, you need something like thunderbolt to plug in a GPU to a running PC
on my 486, i had a drive that wouldn't recognize, unless i plugged it in while the pc was on. Basically shows you how long ago this work, he didnt need to reboot either, just device manager and scan.... then install.
PCIe only detects new devices during post, except for when it is configured to look for hot plugged hardware continuously. The fans spin up because power is still applied through the pins on the slot.
Consumer-grade motherboards don't support hot swapping video cards, but this is possible on servers where you simply can't shut down the entire system just to change one card.
Take out the second one after putting it the same way just want to see if it will act like nothing still or if it will crash also try removing it agein after a reboot to see if it crashes even though it has another gpu
As expected anything to be detected needs a reboot.
If you runs Linux with compiled in kernel hot-plug GPU option, it initializing just in time.
the BIOS is the first thing to detect it and pass it to the Windows
