so Vlink 8x is the cause?I have an idea, let's put the nice blue head sink on SB from NB, and get a fan to activly cool the NB (there are 2 holes around NB for the fan)
AGP 8x is directly link to memory, have anything to do with the Vlink?
Vlink is to transform all system IOs' data from SB to NB, and According to VIA, the Vlink have a fix freq at 266Mhz. If fsb increase, Vlink should remain same otherwise ABit must do something wrong. Still no idea how it crush the agp.
maybe we can suggest Abit to lock the Vlink speed. If fsb get higher, it doesnt have impact on system.
I now know that our initial assumption is wrong, the Agp lock gives us so many
trouble, we start with incorrect point. Damn to the Abit, there engineer can not make the lock work perfectly, so when we are exceeding the 266MHz fsb the biggest ration of 8:2:1 can not make the AGP stay at 66MHz, but I know the chipset is still trying to make it work at 66Mhz again and again until the system hang and we have to reboot it. So unlucky. :-(
