I have the same motherboard, an ASUS P2B Revision 1.02 with BIOS 1011. I have an Intel Pentium III 600MHz Katmai (not the B) running at 100MHz FSB and it works perfectly fine. I also have 2 sticks of 128MB PC-100 EEC SDRAM (single-sided, 9 chips) giving me 256MB of RAM.

I checked and it seems that the 600B you are talking about uses the same 2.0v core voltage and is also based on the 250nm Katmai lithography. Theoretically, it should work at 133FSB, but your board wasn't MEANT to run at 133MHz in the first place. You'd be overclocking your RAM and your Northbridge, as well as your AGP and your PCI bus speeds to push it that high. When I read about people overclocking on this board, the most I've heard being stable was 112MHz FSB. You might want to consider all of this when dealing with this motherboard.

That´s the point, the 133Mhz FSB. If that means stressing out RAM, Northbridge, AGP and PCI, then my interest for that CPU become none. I´ll discard that 600B model and problem solved. The last thing I want for my old hardware is overclock.

I think RAM for 440BX simply needs to be a Dual Sided 256MB module* (not sure if there is anything more needed than that).
*in other words, Low density (like @up said)

1GB didn't worked from start, however trying few things make it work (manually setting stuff with one DIMM and then adding more after each restart, checking each DIMM slot by itself - is also a good start).

You sure this is BIOS file, because it is other type, and as far as i know BIOS files for socket 462 boards are BIN, and will that file work on Award winflash ?

Socket 462 = Socket A = AMD, BX2000+ is Slot-1 😉
You get flasher inside .zip with that beta BIOS.
I think changing file to .bin from .fdc should make it work on any flasher.

PS. Side note :
High End LGA 775 boards don't like high density 4GB DDR3 modules, ie. those that use chips with over 256MB capacity (ie. over 2GB/side) 😁

Well i see overall slot 1 motherboards having trouble running some memory. For example i did try double sided 128 and 256 MB modules on ABIT BE6-II, Gigabyte BX2000, ASUS P2B, (all of the memory for the test was working) and for example 256MB Adata dual rank with HyniX chips wont work on most boards, and similar things to the others, the x3 256MB Micron memory i have is working very well on ABIT BE6-II, but the same memory does not work on the Gigabyte BX2000... I have also AOpen DX34R-U is great dual Tualatin board, but that damn board wont even post, if the memory is not the exact ones that are working on that board, not sure why. So im starting to think there is general problems with the compatibility on the SDram based slot 1 board, maybe the BX4400 chipset or other...

That great board is working only with that x2 types of memory, no other memory did post the board...

So it needs ECC,,, or you've got ECC set in CMOS setup and aren't clearing it each time to test.

Yeah, don't mix ECC ram sticks with non-ECC ram sticks. ECC will have 9 chips per side / non-ECC will have 8 chips (a gap in the middle where a chip could fit but is empty).

I think in the user manual the memory was just SDram, did not see to say only EEC memory. It did say the board is working with ECC as well, but it is working with normal memory as well, or at least the manual says that...

And that's fine. But you can't mix your RAM types. Either use ECC or non-ECC memory. The board can handle EITHER ONE, not both.

P2B is a kickass Slot 1 motherboard.
I have a Rev. 1.10 and it supports the very high end Coppermine. And for those who say to stick to a Pentium II, here is a nice boot image of mine...

Looking at your pics, it looks like the slotket has some kind of VRM on it. For slotkets without any voltage adjustments, Coppermine will not work on P2B <= 1.12.

If you have a PowerLeap iP3/T adapter, you can put a Tualatin 1.4GHz Celeron and run it on any P2B. Technically Tualatin Pentium 3 1.4Ghz will work, but 133FSB is overclocking the AGP bus.

No VRM. My previous cpu was the 1GHz slot 1. And my board has the newer voltage regulator HIP6019BCB that goes down to 1,3V.

Yes, it is. But I have an older revision and maybe it doesn´t fit newer CPUs so well, at least those with 133Mhz FSB. Nothing I´m particulary worried, on the other hand.

The hell where did i say im trying to mix ECC and no ECC ?
Only a retard will do that... What i say is that board should work with both ECC and non ECC memory , but it posts only with the ECC based ones no idea why...

Maybe a stupid question, but I need to clear my thoughts up: would a PIII with 133FSB works fine with 100FSB? For example, my PIII 600B runs at 133/4.5x multiplier. Would it run at 100Mhz/6x? Or a PIII 800 FC-PGA 133/6x at 100/8x.

The multiplier is fixed, so the 600B would run at 450MHz and the 800 at 600MHz .

Thanks, I had totally forgotten the fixed multiplier. My fault.

Unfortunately, it doesn´t boot even with 100/4.5x. Maybe the CPU is faulty or simply the Asus doesn´t like it 🤣 . Either way, I need to test it with another board.

Wish I could come up with a name or keyword to find that old P2B website that had on the board voltage regulator mods and hacks and other tricks.

This thread was just bumped in another one, so here I am 1 month late.

I think you mean this website. It might be helpful to OP if (s)he's up for some modding!
