Diifferences XFX 709i Bios P05V2 & P05

Does anyone know the differences between XFX 790i P05 and P05V2?
fyi -
I have two of there motherboards that are freezing at P05.
We are clean XP installs with the same hardware in two different machines.
We have tried many different BIOS settings, etc but things are no better than default settings.
P05 is much better that P04, but we are still getting random freezes.
Since P05 was pulled from the XFX website, that is not a good sign.

All I need to know is if anyone knows the differences between the BIOS versions...
(the XFX website does not list differences and there support is difficult to get a hold of)
<or>
If anyone has installed the new version P05V2 successfully.

Thanks!
