Duron and A7V multiplier problem

[Tom999]

Hi,

I have an asus a7v with the latest bios and a duron 700. I unlocked my duron cpu using a silver pen and checked with a magnifying glass that the connections for L1 bridges are all there and that they are not crossing over into each other. I set my jumper from jumper free mode to Jumper mode. I then proceeded to alter the dip switches for my Freq. multiplier (to 8X100) and also for the voltages (at 1.6V) and I reached 777mhz, I realized that this was a strange number so I put all the jumpers back to normal (the computer went back to normal at 700). I then tried to overclock again, I tried various combinations with the jumpers, even replacing jumpers with new ones and also the previous combination but the computer would not even start up. The only time the computer will start up is if I set the multipliers and voltages to default and I leave it on jumper free or jumper mode. In jumper free mode I get 700, but in jumper mode I get 777. This is really strange ... my cpu is not overheating - I used arctic paste and a chrome orb = 35 degrees celcius. What is the problem?

I hope someone can help.
I've spent hours.

you did not mention that you used the "dipswitchs", the jumpers are for voltage change and the dipswitchs are for fsb and multiplyer change.
this can also be done in the bois.
read the Asus manual that came with the board carfully, set it to default and get the system to boot-up, shutdown and then set to the next highest (7.5x).
you may also need to change the voltage up alittle with the jumpers.
aways go up in small changes and get the system to boot up and run in windows stably.
if all of this fails(from the beginning), then pull the chip and redue the L1's. "good luck" :)
