All variations of PCI-Express x16 are usually fully counter clockwise compatible.More sophisticated cards ONLY TWO.1 credit cards work throughout older A SINGLE.0 video poker machines, older credit cards work throughout newer casino wars, etc.Everything easily operates at the lowest specification established at sometimes end.

There isn’t any speed change between PCI-E x16 variant 2.0 and 2.YOU, there can be no big difference in maximum bandwidth.Edition 2.1 merely added up front support intended for diagnostic features that will engage in the THREE OR MORE.0 specifications.

In addition, for the GeForce 8400GS the particular version regarding PCI-Express x16 is definitely meaningless.That card is one of the lowest-end models out there.Even $130 cards such as GeForce GTX 550Ti plus Radeon HI-DEF 5770 aren’t fast more than enough to emulate the limits from the original PCI-E x16 position.

Only round the $300 stage do cards become rapidly enough actually gain benefit extra bandwidth associated with version 2.x, and this sort of cards will be literally 20X faster over a 8400GS.

All COUPLE OF.x choices are established by PCIE 3.0 vents, to learn which version your system board supports i might suggest searching up this Desktop when its retail of course , if it seemed to be built next i’d expect you to definitely have a new receipt or something around that can identify them.Failing that you may usually learn the title or a minimum of make connected with it by looking at the bios start-up.

I’m currently by using a XFX Radeon 5830 PCIE 3.1 on an ASUS M4A88TD-V EVO/USB3 which has a 2.0 port and yes it works fine.
