Wen´s interessiert: Habe ich in einem anderen Forum entdeckt ! Und auch schon im Winchester-OC-Thread gepostet...
Wenn man den Ami-Foren trauen kann,haben sie die gleichen Probs wie wir mit dem Board !
Hatte mir damals geschworen NIE wieder ein VIA-Board...tss,tss,tss...
Hier mal ein Auszug zu den FAQ´s...:

pros
AGP-lock working on all rev1.1 boards up to 250 MHz
port80 diagnostic display
vdimm overvolts to 2.82v on highest setting
tracks vtt, OCZ - booster works
cons
CPU-temp readings way off
mixed results with bh-5 and tccd
mixed results with vcore stability
vtt fluctuates and is very unstable above 2.7v vdimm
weak pcb wich means traces on the boards tend to get damaged very easily if the board gets bent just slightly!
read more about it here
possible incompability of this board and antec psu's?
clockgen can only change multis on this board, not the bus speed?
many rev1.0 boards dont have working locks!
TIPS
TIP: you have to disable cool n quiet when ocing
TIP: use slots 1&2 for BH-5, 3&4 for TCCD
TIP: if you have problems with winchester cores on this board flash to bios 1.5 or newer, 1.6 is recommended by abit
TIP: disable fast writes
TIP: with the XP-120 you will NOT be able to put anything in DIMM slot #1
TIP: use the ocz ddr booster in slot #2
TIP: VTT seems to need a reboot to "re-track" after a change
TIP: this board has a very flexible pcb and a very cheap plastic plate around the cpu socket, be VERY carefull with big heatsinks and dont fasten your heatsinks too tight!
TIP: if you cant get any higher make sure all parts of the board are cooled well enough, then start increasingvnb, vsb and vldt(vht)
TIP: if you can get any higher after that try to set vlink to 4 and the ht multiplier to 4x or 3x (800mhz/600mhz)
TIP: if you have a rev1.0 pro board (the revision number is printed on a sticker close to the cpu socket)
try bios 15 and lock the bus, if it doesnt work abit will rma the board
dann ab dort den FSB erhöht.
