Abit BM6, can't o/c Celery2 to 100 FSB

[Maxis]

Bummer,
Just got my Celery 566 (cB0) yesterday, lapped the stock HSF, put some AS2 and drop it to the socket. Runs fine with 66 FSB up to 83 FSB. However, it failed on 100 FSB... I got a blank screen upon restarting, doesn't even go to the BIOS screen.

Settings: multi @ 8.5, FSB 100 (1/3), Sel100/66 @ high, AGP 2/3, Speed Error disabled.

Am I doing something wrong? 100 FSB should be more stable than 83 or even 75 right?

Other information:
BM6 w/ latest BIOS, TZ
ATI Expert 128 (Rage 128 chipset) AGP
2 Dimms @128Mb, all at least PCI-100 compliant (running CAS 2)
CPU Temp @ 83 FSB is about 40c (still waiting for my Alpha PEP66 to arrive)

Any help will be very appreciated!

Forgot to add:
on 83 FSB, I use 1.5V (default) and ran it just fine
on 100 FSB, I tried using up to 1.65V to no avail.

**Reading Abit's manual** Resetting the comp doesn't do anything good, so is rebooting the comp over and over and over again.

Crap

BURN IT IN...a good mantra. run it back at 66fsb or even 83 if it is stable, crank up the voltage (watch temps!) and run benchmarks etc. check out the cpu section, there is tons more info over there.. have fun!

Ok, I can get the BIOS to start in 100 FSB using 1.7V. But Windows still failed to start (hung on the loading screen).

What should I do now? Re-burn BIOS to get more voltage?
Burn-in the CPU?

(btw, in Sandra, what exactly should I choose?) I am running the Burn-in wizard for CPU Benchmark and while having SETI constantly. If my goal is to have 100 FSB stable, is running those two for hours (or days) with 83 FSB and 1.7V enough (CPU temp 42c)? Or do I have to crank-up the voltage even more for burn-in?

Thanks,

okay, a little more detail... go into bios, put it back to 66 fsb, and choose a high voltage, run windows and a few benchmarks to make sure you are not overheating. if overheating, go back and lower voltage, and if you have a some room go back and up the voltage. once you get the highest voltage that won't toast the cpu run benchmarks etc. periodically go back and test higher fsb's. it may take hours, may take days, may take a month, but gradually it will be stable at higher fsb's. probably it won't take too long.

Ok, have done as you've said. Problem is, the highest I can go is 1.7V. I tried the re-flash BIOS trick to get higher voltage that others were talking about to no avail. Does the trick applies only to older BIOS versions (I have the latest)?

I want more voltage, my cooling is sufficient.

As far as I know, the bios flash trick only works on the BH6 and either the BE6 or BX6. Too bad cuz it's a nifty little trick. I used it on my BH6 twice to get voltage selections up to 2.15v. Sorry.

I think you need to burn in just a little bit longer give it two weeks, and keep hunting for a way to increase CV you can also try vidpinning to increase your CV but if you get to high with CV youir going to need a better HSF

vidpinning work fine with me board and it was not that hard to do! check out some post on the section.
