Help! Trouble!..pushing the FSB to high!
 
I read a lot about overclocking the bad axe2 and it seem easy to crank the FSB.

I reduced the multiplier to 7 and crank the FSB frequency to 400. :doh: At 400 MHz, I turn on the computer; the fans turns on and at then no display, and 3 long beep (according to the book mean No Memory!).
I try to boot with a Bios recovery disk, was able to read the floppy but then ...3 beeps!

So it looks like the computer can't see the memory! What can I do to fix it!:help:

Reset CMOS, there should be a jumper to reset your bios back to "stock", popping you battery out does the same thing.

I removed the battery, wait 2 minutes, put it back and I have the same 3 beeps!:doh:

...the reset sw is not on-board.

Try puttin one stick in @ a time, try different slots.
Was the system up and running fine before?

The reset jumpers are right beside the onboard power switch.

Unplug the power cord, press the power button to drain the caps, then move the jumpers from pins 1+2 to 2+3, let it sit there for 30 seconds or so, and return them to 1+2.

This should reset you to default paramaters.

If for some reason the bios has become corrupted, you would need the proper recovery disk and the pins are completely removed from the block.

And you should take this as a lesson learned to not just turn the FSB up to 400 without starting off slow and steady and testing for stability. 975x boards do not like high FSB speeds and there is little to gain from running a higher FSB.

well your half right. you shouldn't just jump the gun to 400fsb and try it. but you are wrong about the higher fsb are worethless. even if you lower the cpu multi and run a higher fsb, you'll still be getting more bandwith, and thats a good thing.

Mmmmmmmm Bandwidth.

I knew it had to have jumpers, I mean WTF board doesn't nowadays?

Guaranteed it was the timings to tight or a small goose in volts needed, myself I find the highest speed it will run then work down from there, lowering the volts and tightening the timings.

Correct, you get more bandwidth. But the little bit to gain is not a good reason for the stability lost. You can get a 5% or so boost from more bandwidth. Google it. That is a big common misconception that it is worth pushing the FSB too high. Same for ram. I never run my ram over 1:1 because the minor performance gains are not worth the possible instabilities and issues.

..I did try that..one stick at the time but I didn't try different slot..
