We are quite confused as to why VIA would go ahead and release a new motherboard based on a slower chipset then what is currently available, namely in their Pentium 4 power-house P4X333 chipset. I just got an email from VIA talking about the release of their new P4PB motherboard based on the older (and slower) P4X266E chipset which only offers official memory support of DDR-266, compared to DDR-333 of other VPSD based motherboards.
During our testing over the last month we've had major issues with the SiS Xabre400 not functioning properly on P4X333 motherboards, maybe this is why... Just food for thought. In any case if you are interested, I have posted the complete Press Release regarding the release of VIA's P4PB motherboard in the VIA section of our forums.
I very much doubt anyone from VIA will attempt to give confirmation, wonders never cease to amaze though.
