I have a bh6 version1.0 and a celeron 600 im trying to overclock. I have SS bios but the voltage only goes to 1.60 or something like that. I can get it to 750 mhz but I cant go beyond that due to the limited voltage the motherboard has.
I heard there was a trick when flashing the bios, but im not sure how to do it. Also, would an Abit Slotkey help boost the voltage? If so, how would that be done and would it have to be done in the bios too?
Actually, all the information i can get on this would be of great help. Thanks in advance.

Just get any regular slotket just as long as it has voltage adjustments, with 133fsb support and you are ok. I personally recommend the MS 6905 MASTER slotkey, i have one, and it goes to 2.4v on my ABIT BF6.
I had that same motherboard last summer with a C-566 CPU and Abit Slotket!!! and didn't have any trouble. I used the 1.75 voltage setting on the slotket and then was able to get more voltage settings in the BIOS. I did update my BIOS, but I've heard that others never did and it still worked.
I've flashed my BH6 1.0 board twice with the SS bios each time gaining a little more on the voltage. You need to set the bios to the highest voltage you have available. Then flash the ss bios using this command line: awdflash bh6_ss.bin /cc /cd /cp /py /sn /cks /r. It worked for me as I now have up to 2.1v for my Celly II 600. When you go back in to the bios your highest previous setting should now be the default voltage and you should have a few options above that.

I set my voltage to max then reflashed and it bumped the voltage from 1.70 to 1.90. I did it again and got it to 2.10v. Set the voltage to 1.90 (system default now) and got all the way to Windows @ 901Mhz. Sweet :)
I crashed out with the blue screen of death after about 3 minutes and then I could only post 901mhz. Bumped voltage to 2.00 (more is better, right?) and then my monitor wouldnt come on. Pulled the bios battery and started over then.
Tried 1.85v @100 this time and almost got to windows before lockup. Bumped to 1.90v and actually got a message saying "Windows Protection Error".
Then i did 1.95v and got windows to come up. First thing was "scanreg~1" error, then (sigh) another lockup. Pulled the battery again and left it at the 675Mhz ive had it at for 3 months now.
Now, would ram cause all this? How can you tell which ram is pc100 and which is not? I have 3 strips of ram and forget where I put what...
Ive also got a Goldenorb on the cpu, a fan glued to the case behind the cpu, a fan on the side of the case, a fan in the front of the case, and a fan on top of my HD's.... and 2 fans on the pwr supply. I wouldnt think cooling is the problem, but I kinda wonder what is.
One more thing... I have a 2.1gb harddrive I got WAY back in the day when it was the largest on the market. Its still my primary and I have a 21gb as a secondary. I can only get above 675Mhz with the 21gb as primary. The 2.1gb locks up right after the DMI (?) check. Anyone else hear of this? Im about to make the 21gb the permanant primary :)
(Sorry for the long post... but thanks in advance for any help)
Cool, I knew that bios flash would work. One thing about voltage, more is not always necessarily better. More is sometimes fatal. Most people agree running higher voltages like above1.8v require very good cooling. Is your chip cBo or cCo? My cCo stepping Celeron II 600 runs 901 with default 1.7v and 1008 with 1.95v. I'm cooling it with an Alpha PEP66 and Arctic Silver thermal paste. The Gorb should be adequate cooling to run at 901 provided the voltage isn't raised too high. What thermal paste are you using between chip and Gorb? As I recall the BH6 was notorious for being finicky with memory. You may want to try one or two sticks in different slots to see how it acts. I have only one 128mb stick of Crucial PC133 memory in mine. PC100 memory should be fine to get you to 901 since the memory will then be running at 100mhz.
cool....
does that work on a Abit VH6 too ??

I got BH6 Version 1.0 too with SS BiOS and Sorry to hear that voltage that can't go high on your board. I didn't make any tricks on flash the bios but in my board, I was allowed to select 1.85V !
With Abit boards, the allowable CPU core voltage settings in the BIOS depends on the default voltage of the chip you use. For example, a cB0 Celeron with a default of 1.5v will allow settings up to 1.75v (maybe 1.7v, I don't remember for sure) and a cC0 chip with a default of 1.7v will allow higher settings in the BIOS.

Is this the only way to tell the difference between cB0 and cC0? Everytime i pulled the bios battery, the system defaulted back to 1.5v and I had to reflash to get it back to 1.9v. If it really is a cB0, what kinda speed should i "expect" out of it? Like i said, ive got 675 right now and its more than i paid for, so anymore would just be a plus.
As far as paste, its just some generic paste that I picked up with the cpu. I didnt really think that mattered, but Im sure every little bit helps. I do know that when I went from a stock fan to a Gorb that i was able to go from 675 to 749 as soon as i turned the computer on.
I'll try switching memory around (i know i have a stick of pc100 in there somewhere...) and set the voltage at 1.7v or 1.8v and see what it does. And again, thank you all very much for the help :)
There are a couple programs (like Sandra) that will identify what stepping it is, but sure sounds like it's a cB0 if the default is 1.5v. Don't worry, they're still good overclockers. I have a Celeron 566 cB0 that I can run benchmarks at 978 MHz. With proper cooling and a goose in voltage, I'd be surprised if you can't reach 900.

ive got a abit bh6 rev 1.0 latest bios version, my 400 celeron had the default 2.0 voltage dont remember how much higher it went, today I put in a 633 and the highest it lets voltage go is 1.85
