Das wär schad...
Scheint aber so zu sein:
"The K8V Deluxe and any board with the Via K8T800 chipset will suffer slightly due to the lack of PCI/AGP bus locks. According to the documentation I have seen the K8T800 chipset is limited to a 1/6 divider. That means that even at the small overclock we achieved here out PCI bus is at 38MHz already. There have been some reports that the PCI bus is locked, but the AGP and HT bus is dependant on the fsb. As explained by Via AGP = CPU/3 therfore we can assume from this formula that with an fsb of 228 (our max stable overclock) our AGP bus would be running at 76Mhz. There still is no clear answer to this. Only time will tell I suppose. It is funny that silk screened onto the motherboard is a list of dip switch settings that show up to a 1/8 divider. Unfortunatly ASUS left the dip switches off the board. If it is possible to get this running, then the Via chipset would be a real winner in the overclocking arena."
So it seems all they did was treat the A64 HT link as an FSB, tagged on a HT->NB chip and then a regular SB as usual. In addition to this, they kept the PCI/AGP clocks at the classical way, synced to the "NB" clock.
Thus AGP is locked at 1/3 of the 200 MHz generator clock, not HT clock (?) which can be divided down by multipliers in the CPU.
Thus they also divide PCI from this, meaning it overclocks with the generator clock.
Duh!
Na dann wirds wohl wiedermal ein K8T800A richten... =)
