and dose the realtec nic do hyperV properly
it will run 16x top 1x bottom if a 1x card is run with 16x card


if you use 8x on bottom and 16x on top you will run 8x 8x


Note:
My 3870x2 enables in PCI-E 16x 2.0 on this mobo..

On the M3A79-T i only could only run PCI-E 16x 1.0 .

Gigabyte did a goodjob at tweaking the PCI-E/2.0/1.0 lane switch on the UD4P.




The only way a 3870x2 can run in PCI-E 2.0 is if the Mobo set the correct code for it. Gigabyte is the only Mobo i have seen @ 2.0 spec while running a 3870x2.

All my other Mobos set PCI-E 1.0 16x...and would keep the card locked in ANOLOG switch mode.This was a big problem with the PLX 1.1 bridge chip and running DVI with Bioses when 3870x2 first came out.

The 4870x2 dose not have this problem, since it uses a different Revesion PLX chip for its bridge.

This UD4P has given me more than i could ask for with the hardware im using ATM.

I havnt even messed with HyperV so i cant comment.....

Im shure someone will know.
