It was late (very early this morning) and I did something stupid!

With my shiney new AMD 1300/100 on my trusty, ultra-stable Asus A7V rev. 1.02 I was reliably overclocking the FSB at 110Mhz and running Win2K rock solid at 1.43GHz. In a foolhardy moment of passion, I bumped the FSB, via the BIOS, to 120MHz and rebooted. Nothing came up and about 30-seconds later the heat alarm came on so I immediatly cut power to the system. I went to bed.

I woke up early this morning, opened the case and took the A7V off "jumper free" mode and set it for 100MHz FSB and 10x on the multiplier (the CPU is unlocked from the factory) which should be 1.0GHz, nicely underclocked. I give it power and... NOTHING still! I figure I've fried the CPU, and while extremely pissed at myself, I dug out the 800MHz that I replaced, set the appropriate jumers/switches, give it power and... NOTHING again!

Did I somehow fry the A7V? At 120MHz FSB, it drops to 1/4 on the PCI/AGP bus, so I don't think I fried any components.

Is there are "BIOS reset" jumper or purge anywhere on an A7V?

Does anyone have ANY ideas?

 
should be a couple of shorting points on the board to reset your cmos to factory default. alternatively, try temporarily removing the m/board battery!
 
Hanpan is right, just clear the C-mos. There should be a jumper on the mobo for that and then make sure that your FSB is set to 133 and not 100 which would give you 1G instead of 1.3G. I hope thats all it is! Good Luck! BTW If you can get into BIOS just try to set everything to safe defalts and go from there. I think you have to be in "Jumperless" mode though.
 
I want to clear my BIOS but I need to know where the short jumper is so I can so it.

That's the information I'm looking for. The battery is for clock and CMOS. I could remove the BIOS altogether and plug it back in five (5) years later and it would have all of its settings. It's not dependent upon the battery to retain information.

Thanks for the try though.

RTFM.

I know your motherboard came with an instruction manual...
 
Read page 57 of your manual. The sholder point are right beside teh battery. Simply unplug the computer (that means powersuplly is off). IF the powersupply is not off you could ruin your mobo so make sure it is. NEst short the two solder point beside the battery. YOu can use a screw driver etc. Finally plug your powersupply back in and start up your computer.
 
Oh, and before anyone with diminished mental capacity would say anything like:

"RTFM.

I know your motherboard came with an instruction manual..."


You should all that that I scoured the user's manual before I posted the original message. What moron wouldn't do that?!

Naturally, because I posted the message in the first place, there is nothing in the manual about shorting the BIOS.
 
That is possible..

Try setting the jumpers back to jumperfree mode and then reboot..

YOu shouldn;t have really hurt anything..
 
Hanpan;

I just did exactly that and it worked GREAT!

Thanks a million!

Apologies to K_Fac for my touchy attitude. A working system does wonders to alleviate a bad attitude 😀

 
Just look in your manual to see if there is a picture of jumper placements on your mobo and it should list the "clear CMOS" jumper if it has one. BTW the only place that a "clear CMOS" option is even metioned in my manual is on that picture.
 
There was a "CLRTC" by the battery which I figured was the culprit, but when I checked the system itself, it was only a solder nub on the board - no jumper - so I shorted that to no avail. I followed Hanpan's secondary advice above about switching back to "jumper free" mode and that did the trick.
