I had been looking for a new bios for my old Lucky-Star 6ABX2V for quite some time and I couldn't find it anywhere.
I managed to find thier homepage (this was almost a year ago) and it was a mess and stayed that way for 6 months or so when suddenly they updated it (these people still have BX-boards in their NEW section)
I found a bios with the right name allthough the info in the site was incorrect and I could just as well have ruined my board.
But it had been sitting on a shelf for ages so I thought why not.
To my surprise, it worked, and even better...
It gave me higher fsb settings!
I had been unable to get more than 133fsb (which is still higher thatn most of these boards will allow) and I just knew that my 550mhz p3 was just waiting for more work.
With the new bios i get 140 and 150mhz settings!
I'm still confused wether it has any higher pci dividers or not but I think that 1/3 is the highest but I have now tried booting at 140 and it startet ok.
I can't test any more now since I still have stock cooling and the board is hanging out from an old AT-case that doesn't fit very well at all.
hoping I can reach 825MHz since that's the highest I can get with 5,5*150 then.
We shall see.
Really nice this is, more WU's.
 
140fsb works fine now when I finally got it working right with all hardware in.
150 is still unstable.
Maybe I should lower memory timings a little...
 
Wow, 140MHz FSB is pretty good for 440BX. Last time I used that chipset was with my Abit BX6 and I was running a 103MHz FSB on my Celeron 300A. Ahhh, the good old days.:)
 
bx chipset will never die...i've got tualy celeron running at 150fsb in my bx board right now. the board will rock at high fsb, you are already getting a great overclock out of that cpu, if you can up the voltage you may get 150. or as you thought, it may be the ram. i had some pc166 that would not run above about 140! so you never know...
 
Well I can't be the ram, I set all timings low and it still gets messy when running Prime and superPI.
How do I get the voltage up then?
There are no jumpers on the board, pin mod maybe or should I voltage mod the regulator as you do on modern boards?
 
I only found voltage mods for the old Deschutes at Katesch (yeye) Pentium 2 slot-1 cpus not for coppermine.
My 550E has 1.65v as standard and I want to bring it up a few notches if possible.
Whick pins is it I need to cover?
Anyone?
