De gynaecologen van TweakTown hebben een Pentium 4 moederbord, de VPSD P4XB-RA die zwanger was van VIA's P4X266A DDR chipset, in de stijgbeugels gehesen en aan een inwendig onderzoek onderworpen. Hieronder een hap uit hun diagnostische bevindingen:
Well, this is what P4 and DDR is supposed to be; fast, reliable and fun. VIA has really shown that they not only have the goods, but why they are the leaders in the DDR race. Now I know a few might be wondering about the fact that our results for the P4XB-RA did come out slower than our SiS 645, but we must remember that the SiS board is running the memory at 333MHz while VIA got almost identical scores with 266MHz RAM. When 333MHz is supported by VIA, then we will have ourselves an ever better looking picture. As for the board itself, its layout, speed and stability were well designed. While there were a few gripes, there was nothing to get into a tizzy about.
