PCI to PCI-e x16 adapter?

Is there any adapter on the market that is PCI when it connects to the motherboard and PCI-e x16 when you connect something to it? If yes please give a link if available.

  2. Or he can be taking about this

    https://www.ebay.com/sch/i.html?_odkw=PCI+Express+x1+To+x16+Adapter&rmvSB=true&_sop=15&afsrc=1&_osacat=0&_from=R40&_trksid=m570.l1313&_nkw=PCI++To+x16+Adapter&_sacat=0

    but if its for a graphics card, it will not work, and if it did, you will not get idea performance

    Cause i asked that question almost a decade ago, looking to turn a old pc to a gaming computer, and the conclusion was trash it and go buy something that atleast use ddr3 ram (back then ddr2 ram was double the price of ddr3, and slower/less capacity).

    If you're truly talking about PCI and not PCI-e, then sorry, definitely not compatible or adaptable to PCI-e x16 or any other PCI-e size. PCI is from 1990, while PCI-e is a considerably newer standard. MSI had the gall to put 2 PCI slots onto my brand new B350 board (probably because they ran out of lanes to do anything useful) and the only thing I could use those slots for was a USB 2.0 expansion card, sound card, or a slow Ethernet adapter. It's a dead standard. They should have put a PCI-e x4 in for roughly the same bandwidth load and it would have been way more useful.

    This is a helpful primer to learn more about it. I guess the newest PCI is still 2x the bandwidth of PCI-e x1, so it's not total shit.

  4. hmmm if latest pci is near pcie-x2 i wonder do they make a entry level gpu on it, and it won't be bottlenecked since low performance and modern architecture for efficiency, but gpu manufacturers would think its useless since new igpu's are probably faster, but yet people using a pci slot most likely have a gpu on their chipset on the motherboard and is very slow. hmmm

  5. I do not consider it buying it, by the way. it was purely for curiosity. If there's PCI to PCI-e x1 and PCI-e x1 to PCI-e x16, technically you can connect a PCI-e x16 device to PCI, right?

    Just because the plug fit, doesn't mean the components will actually works.

  7. Makes sense. But I really want LTT to try it out. He's crazy enough to try it.
