Compatibility PCI EXPRESS 16x and PCI EXPRESS 16x 2.0

DDR5.0
No problem pull. The difference in versions PCI-ex feel only top-end graphics card, like 1070, you and 470 for the eyes and the ears, and even 1050ti will be a lot
And Yes... all PCI-ex compliant

DDR5.0
Guys, you kidding or what? A Google on that, not necessarily to create a theme, I don't mind not argue, but the question I want to buy a graphics card with built-PIII Express 16x 2.0 - connector is known, the same motherboard - asus M3N78 PRO, googled, came out, according to the specifications of this motherboard: expansion Slots: 1xPCI-E has support for PCI Express 2.0. It's not difficult, right? And much easier than to register and create theme.
Meanwhile, but the current graphics card Interface PCI Express Version 2.1 version above.

If you don't know what to write? Just kind of something to crow (still iron that is not yours) and the type of show what a clever and really just a noob :) Although all PCI Express are backwards compatible but the rx 470 will not work on PCI Express 1.0

really? this is documented?

SUSUL1
Don't know about documented but users who had PCI Express 1.0 wrote that is not working. According to the documents they have is one PCI Express 3.0.

Do not want to intervene, but I decided to Google the result under the spoiler. However, for data marked graphics cards PCI Express 3.0 x16, but it is noted in the documents in all modern graphics cards. As we already know, RX 460 absolutely does NOT work on PCI Express 2.0 and below (NO. works, but problems with food). But RX 470/480, it is strange, because there is additional power, and why not.
I found only atkstate, RX 460 graphics card used for data transfer only 8 lines PCI Express 3.0. However, we do not know whether this is a limitation of the GPU itself and whether those implementations, RX 460, which physically have a full set of pins in the connector, half of the signal contact is not involved (in some products, judging by the photos of the boards, the way it is). In any case, for a GPU of this class it should not matter — perhaps with the exception of systems with PCI-Express 1.0, which are more limited by the performance of obsolete CPU than bandwidth of the system bus.
In fact, common sense says shall, except for the RX 460, she's got power from the slot, and because her problem was on 2.0.

Yes, 460й really a problem with PCI 2.0, but people wrote that solves them by raising the frequency of the bus, apparently with the frequency and voltage increases.
In General, the old card the same ate 75W from pci-e and not what didn't happen. Apparently the new cards are not correctly recognized by old BIOS
