Later revisions of the ASUS P2B could als be set at fsb frequencies up to 150 MHz via jumpers. Like for example revision 1.10:

Agreed that 133MHz FSB on a 440BX is overclocking . That said, my 440BX based P3B-F 1.03 is stable running at 133MHz with an FX5900XT , as are many other P3B-F boards .

The Abit BX133 was obviously marketed as being 133MHz capable and I doubt they had to resort to binning chipsets.

My guess would be that 133MHz FSB on the 440BX chipset itself just works, even if out of spec, and that stability issues on certain boards are implementation dependent .

I wonder if I'd be able to overclock my 440BX-based GA-6BA board. What's the highest speed slot 1 CPU available?

Although being a Socket 370 Board, My DFI GCB60-BX/C1 Will run my modded Tualatin Chip at 140fsb with no problems. 150fsb would boot into windows but crash when doing a 3DMark run.

According to this http://www.cpu-world.com/Sockets/Slot%2 ... C242).html and excluding the recalled 1133MHz one, the fastest slot1 CPU is 1GHz P3 with 133MHZ FSB (7.5x multiplier) . The fastest slot1 100 MHz FSB CPU is a P3 at 1GHz (10x multiplier). That last CPU is quite rare and expensive, AFAIK .

Top: 100Mhz FSB -> 1100 MHz (SL5QW) nevermind only with slocket

Been working on my Via C3 1.2ghz Nehemiah Machine the past week and its making good progress. Windows 98 Installed. I'm playing about with Setmul/CPUSPD and Rayers SMB. Hoping to write some batch files for certain CPU speeds. Running a Awe32 with a Dreamblaster X16/SW60XG/TB Maui in the sound. GF2 GTS for Gfx. Really enjoying this machine so far.

Very nice cabling.
And the ODD/FP's match and fit perfectly!

Got busy with literally every computer I've got at home.
Currently I'm moving all my computer stuff out of the computer room.

Spent hours having "fun".

Best thing is your to come: in a week or two I can move all my stuff back, when I finished my new laminate floor and put in some new cabinets.

Current Ikea cabinets were made of some cardboard, bending down quite a bit. Not so solid after all... or they just can't handle 40 hard drives and 15 cd/dvd drives on ones shelf :')

Not sure aboutOC'ing but I think you need a revision 3.x board for the best 100MHz support (up to 1GHz). My revision2.5a board is limited to 800MHz (850 at a push but not too stable)

Out of curiosity, how did you get an 8x AGP video card to run in a 1x/2x AGP slot?

Geforce FX cards are universal AGP capable . They can run in a3.3 volt AGP 1.0 slot at AGP 2X speed .

Also, I just checked, and my GA-6BA board is Rev 3.0. It should support 133mhz FSB CPUs?

I'm having friends over tomorrow evening for some retro gaming on multiple computers, so I've been going through and testing everything that I'm going to be using is in working order -
IBM XT 5160
Dell OptiPlex 486 DX2-66Mhz
Sinclair ZX81
Commodore VIC-20
Sinclair ZX Spectrum +2A
Acorn BBC Micro Model B
Acorn Electron
Amstrad CPC 464
Commodore 64
Commodore Amiga 1200

+ assorted peripherals for each system.

Also came up with a nifty idea for the BBC & Electron whilst they're not in use on their respective screens - coded a simple on-screen message in BASIC, making use of flashing colours.

Additionally I made some finishing touches to a simple Welcome Presentation that I coded in BASIC on the ZX81. With a silly interactive Easter Egg included in the code. 🤣

I know Woodgrain 486s are probably a dead fad at this point, but I couldn't help myself.

I got my VLB IDE card to finally play nice. Apperently it doesn't like the second IDE channel even so much as being touched. So I hooked the CD up to my soundcard instead.

a 16mb ram and 5/4 floppy disk drive update are on the way. But otherwise this DX4 build is pretty much done ^^

LGR approves of the Woodgrain 486. Got my Socket 7 system up to speed by adding the aweutil /s at the end of the games.bat file when the exit key or after the game is done to reset the AWE32 music sound font.

After receiving some sewing machine lubricant in the mail, and to a lesser extent getting bored, I decided to go around and give my old fans some love. In the case of my 98 machine, it didn't change too much thanks to there mostly being old tiny CPU fans in use in that, it had a rather nice impact on my old Macs. Specifically, I managed to get the single fan inside my 400MHz G3 to be audibly quieter. In the case of my DP 1.42GHz G4, I managed to bring the temps down rather nicely along with making it just a wind tunnel, instead of having it be a loud wind tunnel

Above is the pre-lubed temps after a few minutes on the desktop.

And here is where they are now, following geekbench benchmarking.

I had no idea the 1GHz 100MHz chips were so rare - I got given a handful of these a few months ago and currently only have one board that will accept them!

They are certainly nice, but I still prefer an adapted Tualatin 1400 512K on a capable slot 1 board. Even if run at only 1050MHz (100MHz FSB), it should is quite a bit faster than a 1000MHz 100MHz FSB P3 .

The only slot one board I have that's P3 compatible past 450mhz (thx intel se440bx) is a QDI Brillianx 1s/2000 which I don't think supports the tualatin at all?

No slot1 board officially supports a Tualatin CPU, AFAIK .

AFAIK, most Coppermine capable slot1 440BX boards can run a Tualatin CPU with an appropriate (usually modified) socket 370 to slot1 adapter to
a) adapt the slightly different pinout (always required)
b) provide the lower voltage that a Tualatin CPU requires (some boards have VRMs that can already do that, others require a socket 370 to slot1 adapter with its own VRM. The PowerLeap IP3/T is the only adapter with an integrated VRM) .

EDIT: Even the SE440BX can work with a Tualatin with an adapter (more recent BIOSes probably have lockouts, knowing Intel), and so can the QDI Brillianx 1s/2000, according to this --> https://web.archive.org/web/20060202072822/ht … mpatibility.htm

EDIT2: There is a big gap between what board manufacturers officially supported and what can work safely with the proper adapter .

EDIT3: Additional cooling to the VRM circuitry is a good idea if running a VRM at lower voltage than expected by the board manufacturer (the extra voltage drop generates more heat). See http://duhvoodooman.com/powrleap/LFL/Slot-T_1.htm
