A7V-133 POST problems....

[bullterror]

I have an asus a7v-133 with an amd duron 800 and I also have an athlon axia 1333
My duron runs great at 950mhz [email protected]
my athlon runs great at 1400 [email protected]
I set the speeds in the bios, and it runs great until I reboot
then it won't post and I have to power down, run it at a lower speed for a bit, then set the speed back up.
Temps are not a problem... Everything runs great until I reboot
Why would this happen?

I believe you have to set the jumper on the mainboard for the FSB to 133. That way when it boots, it starts at 133 instead of the default of 100. That's why the Duron probably reboots at the same speed but not the T-bird.
The problem is in the default boot speed for the CPU and the BIOS will not save the 133 FSB selection.

I tried that. It's not just the athlon, it the duron too
the duron will run great at 950 for hours, I reboot, and then it won't post
the athlon will run at 1400, semi-stable (I need to get a good fan) and then when I reboot, no post.
it does it if I set the speed and voltage on the mainboard, too

Mine did the exact same thing. Would run completely stable but if I changed the vcore from auto to 1.65 - 1.75 it wouldnt ever post on a hot reboot. I could never get it to work so I said screw it and went with the KT7A from ABIT. I still got the board if I may want to scre with it more, but I seriously doubt it.

Same here, i believe the problem is using jumper free mode with the a7v133, apparently it dosen't control the voltages well. I can run in 11 x 133 with auto-voltage and run fine, but if i try to set the voltage to manual, i can't reboot... It would be really nice to control the voltage manually, because as it is, i run with 1.85-1.87 vcore on "auto" mode and it makes my tbird run hot. I'm SURE i could run fine with only 1.84-1.85 but i have yet to figure out how to do this consistently. Any thoughts? L7's??

Maybe I should start a small web page to document this issue so we could raise this to the attention of asus? but I'm gonna need alot more accounts of people having the same problem.
