It seems like my memory isn't what it used to be. The two "1133MHz" pentium 3 coppermine chips I claimed to have are in fact 1100MHz SL5QW Coppermine Pentium 3's. 100Mhz FSB too. Weird chips.
And perhaps even better chips in a way. These would make for some awesome 440BX upgrades 😋
I think the fastest P3 @ 100MHz FSB I have is like 850MHz or so?
Ok so I tried to get the SL5QW to run in a 440BX board with a slotket as per your recommendation but I didn't get very far.... 🙁 Here's what I was able to do today:
The base test system is a Abit BE6-II board / Pentium II 333 @ 500MHz / 256MB PC133 SDRAM @ 100MHz CL2 / Creative 3D Blaster Annihilator 2 PRO / 20Gb Quantum Fireball HDD / 350W HP PSU with -5V / Creative AWE64. What I did first is swap the P2-333 for a slot 1 P3-1000 (FSB133 unfortunatly) I had in my CPU box just to check if the board would run correctly with a coppermine CPU - so far so good, the system posted, and I was able to run at 750MHz (7.5x100) stable (tested in 3dmark 2000 and quake3 - several runs). I did try 1GHz (133x7.5) but the Geforce 2 didn't like that and would bsod when loading windows. Then I got sidetracked and tried my new Chinese Geforce FX5500 PCI witch worked a treat.

After loosing an hour on that, I started going trough my slotket box, but it's pretty slim pickings in there. I don't have anything as fancy as a Tualatin compatible slotket, but I do have a couple of coppermine ready slotkets - specifically something silkscreened with AA370TS. Don't know the manufacturer, but one was in an AT form factor slot 1 board with a VIA 694 chipset running a 850MHz SL5Q Coppermine Celeron while the other came with my Asus P3B and a 750MHz / FSB 100 SL462 Pentium 3.

I tried the slotket with the 1100Mhz P3 and no dice. The BE6 would not post. So I reset CMOS and installed the 750Mhz SL462 in the slotket. Still no POST. I took the slotket out, washed the goldfinger with IPA and ran it over with a bit of 1000 grit sand paper, then washed it again with IPA and the BE6 poseted. I was able to boot into windows and run Quake 3 and 3DMark 2000. Results were in line with the slot 1 P3 1000 running at 750Mhz.
I then moved on to the SL5QW, and the system still refused to POST. Only after swapping the RAM stick for a double sided PC133 stick I was able to post.

I was able to boot into windows... and the PC froze. Tired it a couple of times. The second time it froze before loading desktop icons and the 3rd time it froze at the win98 loading animation. I rebooted, went into bios and checked voltage and temps.... the CPU was already at 55 That's a bit hot for a pentium 3 as far as i know 🙁 . I then bumped up the voltage from 1.75v to 1.8, and was able to load windows, but as soon as I launched 3DMark it would freeze again. This time BIOS was showing 58-60C.... So I stopped testing.
I'm guessing either my Abit doesn't like the chip, the chip is overheating with that dingy cooler, or my slotket is crap. After testing the SL5QW in my Asus P3B and getting similar results I was leaning towards the latter... since the chip worked fine in my MSI master dual socket 370 board and in my Asus CUVX-M. But it did so with MUCH BEEFEER cooling.... in the CUVX-M at least I used an 80mm socket A cooler, otherwise it would climb up to 68C while gaming...
As to not de-rail this thread, I'll open a new one after I have time to do a bit more investigation.
