Like this Superpi 1M score!

Huh? Does it really take over an hour? Pentium MMX only takes 15 minutes.
I reckon Skyscraper benchmarked it at 33MHz.

I recently tried Windows 7 on a Cyrix MII-233GP and managed to get running, even with Aero working, but in the practice, it was too slow to be usable

Machine specs:
Cyrix MII-233GP (200 MHz)
EPoX EP-MVP3G2 Motherboard
384 MB RAM
Geforce 6200 AGP
Realtek RTL8139 LAN card
2x 80 GB HDD

As well, i tried some newer software on 6x86 P166+ using Windows 2000 w/ BWC extended kernel since XP won't boot on it, these tests were done without the CPUID hack

Machine specs:
Cyrix MII-233GP (200 MHz)
EPoX EP-MVP3G2 Motherboard
384 MB RAM
Geforce 6200 AGP
Realtek RTL8139 LAN card
Soundblaster Vibra 16S
2x 80 GB HDD

Known not working or begin broken:
Windows Media Player 9
Microsoft Office 2003
.net Framework 2.0
Firefox 10esr+
3DMark99/2000/2001SE/03 (99 MAX FPS counters are broken, 2000 complains CPU lacks MMX and closes istelf, 2001SE complains as well and starts anyway, but first test fails, 03 starts but not all tests can be done and sometimes triggers 0x1e BSOD)
Palemoon 27.9.6 XP Mod IA32 port
Seamonkey 2.40
FRAPS 3.4.7

Office 2003 and XP work just fine on my MII-433.

I had a Cyrix 233mhz 75x2.5 for many years

At one point I upgraded to a Ss7 sys598 and ran the bus 2x95mhz gave a nice speed boost

Now I find out many motherboards had undocumented and stable 120mhz and 133mgz FSB settings

If the old Cyrix chips can do 1x would be interesting to run an old pr200 on a 133mhz fsb.

I was able to get the original Cyrix 6x86 chips to run with 1x, but which SS7 boards have a stable 133 MHz FSB setting?

In my testing of the original 6x86 processor, I have found them to be rather problematic, as they are missing some pentium features.

The 6x86MX/MII processor, on the other hand, showed excellent compatibility and I have not found any problems with them running software.

Gigabyte GA-5AX (rev 5.2) supports 135 and 140 mhz,but not 133. ASUS P5A only does up to 120 mhz. No idea if other boards have that setting though.

I can say FSB >100 MHz is really questionable on a Super 7 system because of the external cache and the PCI/AGP clocks not begin able to cooperate. at 133 mhz the cache wouldn't handle it and the AGP would be running at the astronomically high clocks of 89 mhz plus i don't think they have an 1/4 PCI divider like 440BX boards generally have

BX has the pci divider but agp also runs at 89mhz when overclocked to 133fsb. It is not a problem for many many cards. But I do agree on the cache, overclocking with working cache is around 110mhz fsb on a p5a/p5a-b and benchmark stable you can try 115mhz fsb with working cache (and need luck).

My GA-5AX (5.2) worked with external cache enabled up to 125 MHz and without cache 135 MHz. 😈

My m598 would run 133mhz FSB creatively using cpucool (with cache)
