sorry for delay guys, but here's the deal :

-no overvolt jumper. mem upto 2.8v / vcore upto 1.85v. however this board clocks much better at lower volts than kd7 / 8k9a2+. memory voltage mod should be easy. i think v-mem controller is located in upper right corner of mobo. if DDTung asks i can give some more details.

-bios is full of o/cing goodness. ram timings from cas1/1/1/1 to cas3/3/3/8. agp lock at 50mhz,60,66,67,68,69..... upto 100mhz in one mhz increaments. agp 8x can be disabled in bios as well. i tried it with ti4200 agp 8x.

- i was able to o/c 2700+ (unfortunately locked on this mobo) upto 13x191 ram@2.8v / v-core 1.85v. on air cooling.

- ram can be ran at insane speeds. 166fsb+ ram 33,66,100,133,200% !!! find me any ram able to at least post at over 300mhz/600ddr.

- agp voltage 1.5/1.6/1.7 which really helped this ti4200 to operate at 100mhz agp.

- IMO, this mobo is more stable than kd7. i think it's the first decent mobo from Asus, lol.
